Description

  The present invention relates to distance learning such as distance learning and self-study education, and more particularly to an apparatus and a program for authenticating whether or not a viewer is viewing an actual distance learning program.

  In distance education, through the provision of programs using radio wave media such as TV broadcasts and radio broadcasts, magnetic and optical recording media such as VTRs, CD-ROMs and DVDs, paper media such as books and booklets, and electronic media such as the Internet, Students are learning. Conventionally, in distance learning such as distance learning, self-study education, etc., students are given examination questions and submitted answers to confirm the level of understanding of the content, which is used as a criterion for the student's learning level.

  FIG. 22 is a diagram showing an audiovisual authentication method in the case where distance learning is performed using satellite broadcasting as a radio wave medium. In the figure, 1 is a video material of a program, 2 is a broadcasting station, 3 is a broadcasting satellite, which may be a geostationary orbit satellite, or a low orbit satellite. 4 is a satellite broadcast receiving tuner and 5 is a television. A communication line 8 may be a public line or a dedicated line. 12 is an answer sheet, 13 is a facsimile, 14 is a mail, and a courier service by a private company may be used. Reference numeral 15 is a distance education management center.

  In the distance education thus configured, the video material 1 as an educational material is broadcast as a program via the broadcast station 2 and the broadcast satellite 3. The viewer views the program from the television 5 via the satellite broadcast receiving tuner 4. After viewing the program, the viewer enters an answer on the answer sheet 12 and sends it to the management center 15 by the facsimile 13 via the communication line 8 or sends the answer sheet 12 to the management center 15 by mail 14.

  However, in the conventional distance learning, the presence or absence of the viewing of the student cannot be surely captured. That is, although a confirmation test is performed to confirm viewing by distance learning, there is a problem that it is not known whether or not the program is actually viewed only by confirming the degree of understanding of the answer to the test question. Even if the student does not watch the program, he / she can give a correct answer if he / she knows it.

  In addition, there is a problem that it is not possible to verify the identity of the answer sheet 12 submitted as an answer to the test question.

  Furthermore, since the collection of responses is by mail 14, facsimile 13 or the like, there is a problem that it takes time to confirm viewing.

  As an invention for solving these problems of conventional distance education, an invention disclosed in Patent Document 1 is known. In Patent Document 1, a viewing confirmation code consisting of a predetermined character string unique to the audiovisual program viewed by the viewer of the audiovisual program is transmitted to the audiovisual authentication subject by the viewer, whereby the audiovisual program by the viewer is transmitted. Disclosure of the invention for authenticating the viewing of

On the other hand, the viewer of the audiovisual program receives a viewing confirmation code consisting of a predetermined character string. When transmitting to the audiovisual authentication entity through the audiovisual terminal operated by the viewer, it may be necessary to remove the line of sight from the audiovisual program being viewed by the viewer and check the viewer's hand operating the audiovisual terminal There was a problem. In particular, it is effective to perform viewing authentication by an audiovisual authentication entity at the timing of presenting an important information portion in an audiovisual program, but the viewer is presented to the viewer in an important information portion in the audiovisual program. As a result of the viewer removing the line of sight from the audiovisual program in order to enter the viewing confirmation code to the audiovisual terminal operated by the viewer, the viewer misses the explanation of important video or subtitles presented in the audiovisual program. It is possible to point out the possibility of end.

  The present invention has been made to solve the above-described problems. An audiovisual terminal, an audiovisual authentication system, and the like suitable for performing audiovisual confirmation of an audiovisual program by a viewer, particularly for audiovisual authentication in distance learning, and the like. An object of the present invention is to provide a program for controlling the apparatus.

  In order to achieve the above object, the audiovisual terminal of the first aspect is, for example, an audiovisual terminal 20 operated by a viewer of the audiovisual program shown in FIG. 1; reproduction means 21 for reproducing the audiovisual program; and the audiovisual terminal Based on the “operation instruction information 101” (see FIG. 3) specific to the audiovisual program in which the program providing entity that provides the program requests the viewer to perform a predetermined action at a timing specific to the audiovisual program. Action instruction means 22 for instructing the action; each time the action is instructed by the action instruction means 22 for transmission to an audiovisual authentication entity that authenticates that the viewer is viewing the audiovisual program normally. A motion sensor 23 for detecting a response action of the viewer performed by the viewer; and an audiovisual authentication system possessed by the audiovisual authentication entity to obtain the authentication of the viewing of information output from the audiovisual terminal 20 40 (see FIG. 8); a transmission means 29 for transmitting the information obtained from the detection result detected by the motion sensor 23 into a signal that can be transmitted by the transmission means 29. Means 24.

  For example, the reproducing means 21 shown in FIG. 1 presents the audiovisual program provided by the program providing entity to the audiovisual terminal 20 operated by the viewer by video and audio. The reproduction means 21 has a liquid crystal display screen (see FIG. 6) and an air conduction speaker (not shown), and presents an audiovisual program to the viewer by video and audio.

  For example, the operation instruction means 22 shown in FIG. 1 includes “operation instruction information 101” specific to an audiovisual program in which a program providing entity that provides an audiovisual program requests a predetermined operation from the viewer at a timing specific to the audiovisual program (FIG. 3). To the viewer). The operation instructing unit 22 instructs a sample of a predetermined operation to be performed by the viewer on a part of the liquid crystal display screen (see FIG. 6) of the reproducing unit 21 by animation or characters (see FIG. 6). In addition, a notification sound is generated by an air conduction speaker (not shown) included in the reproduction means 21 in order to alert the viewer.

  For example, the motion sensor 23 shown in FIG. 1 receives the viewer every time the operation is instructed by the operation instruction means 22 in order to transmit to the audio-visual authentication entity that authenticates that the viewer is normally viewing the audio-visual program. It is a detection apparatus which detects the response action of the viewer who performs. Here, the movement refers to the movement of the viewer's body or a part thereof, particularly the hand itself. This movement is one-dimensional, two-dimensional or three-dimensional. In other words, it can be detected by the motion sensor 23. The motion sensor 23 includes, for example, a three-axis six-degree-of-freedom acceleration sensor (not shown) and an auxiliary camera (not shown) that detects the viewer's response operation by photographing the viewer.

  For example, the transmission means 29 shown in FIG. 1 transmits the information output from the audiovisual terminal 20 to the audiovisual authentication system 40 (see FIG. 8) possessed by the audiovisual authentication entity in order to obtain viewing authentication. Specifically, the transmission means 29 is an information communication device (wireless LAN communication device (router)) (not shown) that performs information communication by connecting wirelessly to a public wireless LAN (Local-Area-Network) (not shown). is there.

  For example, the signal converting means 24 shown in FIG. 1 converts “information relating to the viewer's response operation” obtained from the detection result detected by the motion sensor 23 into a signal that can be transmitted by the transmitting means 29. The signal converting means 24 first acquires the detection of the response operation of the viewer detected by the motion sensor 23 as a detection result (primary information) based on an “authentication standard” determined by the audiovisual authentication subject. Further, the signal generating means 24 creates secondary information (derived information) that is information obtained by indexing the response action by the viewer from the detection result (primary information) based on the “authentication standard”. Further, the signal generation means 24 creates tertiary information (derivative information) that is an authentication result from the secondary information that indexes the response action by the viewer based on the “authentication standard”. In this way, the signaling unit 24 transmits “information related to the response operation of the viewer” obtained from the detection result detected by the motion sensor 23 based on the “authentication standard” determined by the audiovisual authentication subject, by the transmission unit 29. Signal as possible signal.

  With this configuration, the viewer of the audiovisual program can reproduce and view the audiovisual program by the reproduction means that reproduces the audiovisual program provided in the audiovisual terminal operated by the viewer. In addition, the program providing entity that provides the audiovisual program instructs the viewer to perform the operation based on the operation instruction information specific to the audiovisual program that requests the viewer to perform a predetermined operation at a timing specific to the audiovisual program. By the operation instruction means, it is possible to grasp the operation requested by the program provider who provides the audiovisual program as the instruction of the operation instructed by the operation instruction means. In addition, the viewer performs the operation every time the operation is instructed by the operation instruction means to transmit to the audio-visual authentication entity that authenticates that the viewer is viewing the audio-visual program normally. The motion sensor that detects the response motion of the viewer can detect the response motion performed by the viewer as detection by the motion sensor. In addition, the information output from the audiovisual terminal is transmitted to the audiovisual authentication entity by transmission means for transmitting the information output from the audiovisual terminal to the audiovisual authentication system of the audiovisual authentication entity to obtain the authentication of viewing. can do. In addition, the viewer response detected by the motion sensor by the signalizing means for converting the information related to the response operation of the viewer obtained from the detection result detected by the motion sensor into a signal that can be transmitted by the transmitting means. The motion detection can be converted into a signal that can be transmitted by the transmission means as information related to the viewer's response motion obtained from the detection result detected by the motion sensor. For this reason, based on the information about the response operation of the viewer obtained from the detection result detected by the motion sensor transmitted by the transmitting means, the viewer by the audiovisual authentication subject has viewed the audiovisual program. You can get certification about.

  Further, the audiovisual terminal of the second aspect is the audiovisual terminal of the first aspect. For example, the signalizing means 24 included in the audiovisual terminal 20 shown in FIG. 1 is the response operation and operation of the viewer detected by the motion sensor 23. When it is recognized that the operation instructed to the viewer by the instructing means 22 matches with a predetermined standard, an “operation authentication” that recognizes that the response operation of the viewer is a valid response operation is output. Has an authentication unit 24a (see FIG. 2).

  For example, the signal converting means 24 shown in FIGS. 1 and 2 has a predetermined standard (for example, an audiovisual authentication entity) that determines the response action of the viewer detected by the motion sensor 23 and the action instructed to the viewer by the action instruction means 22. , “Certification criteria” that stipulates that “the motion is the same when the difference in acceleration is at most a predetermined value (index value) (eg, 1.2 G (1.2 times the gravitational acceleration on the earth))” ) And an authentication unit 24a (see FIG. 2) for authenticating the matching. In addition, the operation authentication unit 24a included in the signal converting unit 24 uses a predetermined reference determined by the audiovisual authentication entity for the response operation of the viewer detected by the motion sensor 23 and the operation specified by the operation instruction unit 22 to the viewer. In the case of authenticating a match, “operation authentication (audiovisual terminal) 103a” (see FIG. 5) (tertiary information) is output.

  With this configuration, the viewer of the audiovisual program can use the signalizing means provided in the audiovisual terminal operated by the viewer by the response operation of the viewer detected by the motion sensor and the operation instruction means. An operation authentication unit that outputs an operation authentication that recognizes that the response operation of the viewer is a valid response operation when the operation instructed to the viewer is found to match with a predetermined standard; Accordingly, it is possible to obtain the operation authentication that recognizes that the response operation of the viewer is an effective response operation. Further, the operation authentication can be transmitted to the audiovisual authentication system possessed by the audiovisual authentication entity by a transmission means provided in the audiovisual terminal. Therefore, based on the operation authentication, it is possible to obtain authentication that the viewer has viewed the audiovisual program by the audiovisual authentication subject.

  Further, the audiovisual terminal of the third aspect is the audiovisual terminal of the first aspect. For example, the signalizing means 24 provided in the audiovisual terminal 20 shown in FIG. 1 is the response operation and operation of the viewer detected by the motion sensor 23. When it is recognized that the operation instructed to the viewer by the instructing means 22 coincides with a predetermined standard, the viewer recognizes that the response operation of the viewer is a valid response operation. ) 103a ”(see FIG. 5), the total number of motion instruction information 101 (see FIG. 3), and detection of the viewer's response motion detected by the motion sensor 23 The response authentication unit 24b that outputs “viewing authentication (audiovisual terminal) 105a” (see FIG. 5) based on the “operation response rate” when the “operation response rate” for comparing with the total number satisfies a predetermined criterion. 2), and a clock 28 that outputs a time at which the audiovisual terminal 20 performs control processing, and the clock 28 outputs from the time when the operation is instructed to the viewer by the operation instruction means 22 output by the clock 28. “Time required for response by the viewer” up to the time when the response operation of the viewer is detected by the sensor 23 satisfies a predetermined criterion. The authentication unit 24c (see FIG. 2) for outputting the authentication (audiovisual terminal) 104a ”(see FIG. 5); and having at least one authentication unit selected from the group consisting of the three authentication units Based on the authentication result output by the authentication unit, “information relating to the response operation of the viewer” is output, and “information relating to the response operation of the viewer” is signalized.

  For example, the audiovisual terminal 20 illustrated in FIG. 1 includes a clock 28 that outputs a time at which the audiovisual terminal 20 performs control processing.

  1 (and FIG. 2) includes a response authentication unit 24b (see FIG. 2) and a time authentication unit 24c (see FIG. 2) in addition to the above-described authentication unit 24a (see FIG. 2). 2).

  For example, the response authentication unit 24b (see FIG. 2) included in the signalizer 24 shown in FIG. 1 (and FIG. 2) performs the total number of “operation instruction information 101” (see FIG. 3) and the viewer detected by the motion sensor 23. The “motion response rate” (secondary information) for comparing the total number of detected response motions with the predetermined action (for example, “motion response rate”) "Authentication criteria" defined as "Authenticate when" is greater than or equal to a predetermined value (for example, "80%") ")" Viewing authentication (audiovisual terminal) 105a "(Fig. 5) (tertiary information) is output.

  For example, the time authentication unit 24c (see FIG. 2) included in the signalizer 24 shown in FIG. 1 (and FIG. 2) is configured so that the time when the viewer's response operation is detected by the motion sensor 23 output by the clock 28 is the clock 28. Within a predetermined time range determined by the audiovisual authentication entity from the time when the operation is instructed to the viewer by the operation instructing means 22 (for example, “the time required for the viewer to respond based on“ authentication criteria ”). If the time is within a predetermined value (for example, within a range of 3 minutes), “the time required for the viewer to respond” (secondary information) is deemed appropriate. “The viewer required the response “Time authentication (audiovisual terminal) 104a” (see FIG. 5) (tertiary information) based on “time” is output.

  For example, the signaling means 24 shown in FIG. 1 (and FIG. 2) includes an operation authentication unit 24a (see FIG. 2), a response authentication unit 24b (see FIG. 2), and a time authentication unit 24c (see FIG. 2). It has at least one authentication unit selected from the group consisting of three authentication units, and based on the authentication result output by the authentication unit, “information related to the viewer's response operation” (for example, “operation authentication”). , Response information, positive information that satisfies all the authentication criteria of time ", or negative information that" does not satisfy the operation authentication criteria ", for example) (tertiary information) Create and signal.

  With this configuration, the viewer of the audiovisual program has a clock that outputs a time at which the audiovisual terminal operated by the viewer performs control processing, so that the audiovisual terminal output by the clock performs control processing. On the basis of the time when the audiovisual program is performed, it is possible to obtain authentication that the viewer has viewed the audiovisual program by the audiovisual authentication entity. In addition, the signal converting means included in the audiovisual terminal is one in which the response operation of the viewer detected by the motion sensor and the operation instructed to the viewer by the operation instruction means match in accordance with a predetermined standard. The viewer's response operation is an effective response operation, and the viewer's response operation is an effective response operation. Acknowledged operation authentication can be obtained. In addition, the operation authentication can be transmitted to the audiovisual authentication system possessed by the audiovisual authentication entity by the transmission means provided in the audiovisual terminal. Therefore, based on the operation authentication, it is possible to obtain authentication that the viewer has viewed the audiovisual program by the audiovisual authentication subject. In addition, the signalization means included in the audiovisual terminal has a response rate that compares the total number of the operation instruction information and the total number of response operations detected by the viewer detected by the motion sensor satisfying a predetermined criterion. Further, by providing a response authentication unit that outputs viewing authentication based on the operation response rate, viewing authentication based on the operation response rate can be obtained. Also, the viewing authentication based on the operation authentication rate can be transmitted to the audiovisual authentication system possessed by the audiovisual authentication entity by the transmission means included in the audiovisual terminal. Therefore, based on the viewing authentication based on the operation response rate, it is possible to obtain authentication that the viewer has viewed the audiovisual program by the audiovisual authentication entity. Further, the signal converting means included in the audiovisual terminal is configured such that the time when the response operation of the viewer is detected by the motion sensor output by the clock is detected by the operation instruction means output by the clock. If the time required for the response by the viewer is appropriate when the time is within a predetermined time range from the time when By including the authentication unit, time authentication based on the time required for the viewer to respond can be obtained. Also, time authentication based on the time required for the viewer to respond can be transmitted to the audiovisual authentication system of the audiovisual authentication entity by the transmission means provided in the audiovisual terminal. For this reason, based on the time authentication based on the time required for the viewer to respond, it is possible to obtain authentication that the viewer has viewed the audiovisual program by the audiovisual authentication subject. Further, the signaling means included in the audiovisual terminal is one or more authentications selected from the group consisting of the three authentication units including the operation authentication unit, the response authentication unit, and the time authentication unit. And output information related to the viewer's response operation based on the authentication result output by the authentication unit, and signal the information related to the viewer's response operation. It is possible to obtain authentication that the viewer has viewed the audiovisual program by a derivative composite audiovisual authentication entity based on operation authentication, viewing authentication, and time authentication information.

  Further, the audiovisual terminal according to the fourth aspect is the response of the detection result detected by the motion sensor 23 included in the audiovisual terminal 20 shown in FIG. 1 in the audiovisual terminal according to any one of the first to third aspects. A response operation recording means 25 that records as “operation history”; a detection result that is detected last by the motion sensor 23 and a detection result that is detected last by the motion sensor 23 in the “response operation history” that is recorded by the response operation recording means 25. Response operation comparison means 26 for comparing with other detection results except for; and based on the result of comparison by the response action comparison means 26, the detection result last detected by the motion sensor 23 is included in the “response operation history”. When it is determined that the detection result matches with a predetermined standard, the program providing entity of the audiovisual program is set as the target of the audiovisual program. Authenticate as the viewer himself that and a viewer authentication means 27 to output the "audience Authentication".

  For example, the response operation recording means 25 shown in FIG. 1 records “operation response information 102” (see FIG. 4) that records the detection result detected by the motion sensor 23 as its configuration information (“response operation”). This is a database management system for recording in the response operation history database 31 which is a mass storage device (hard disk / memory) connected to. The response operation history database 31 can record information of “operation response information 102” including the detection result detected by the motion sensor 23 as its configuration information (“response operation”) as “response operation history”. In the “motion response information 102”, a detection result (primary information) in which a response motion of the viewer is detected by the motion sensor 23 is recorded as “response motion” information constituting the “motion response information 102”.

  For example, the response action recording means 25 shown in FIG. 1 has the “response action history” recorded in the response action history database 31 (that is, the detection result (primary information) detected by the motion sensor 23 as the response action of the viewer). Information of “operation response information 102” (see FIG. 4) included as information can be searched and extracted by an arbitrary search condition. Specifically, for example, the response action recording unit 25 searches and extracts another detection result ("action response information 102") based on an instruction of the same action performed by the same viewer from the "response action history". .

  More specifically, the detection result detected by the motion sensor 23 shown in FIG. 1 (information of “response operation” constituting the “operation response information 102” (see FIG. 4)) is related to the related information by the signalizing means 24. By being added, it is recorded in the response operation history database 31 as “operation response information 102”. As information constituting the “operation response information 102”, “operation instruction information 101” (see FIG. 3) that is information corresponding to the “operation response information 102” is recorded. Further, as information constituting “operation instruction information 101”, information of “viewer ID”, “instruction operation”, and “instruction ID” is recorded. For this reason, the response action recording unit 25 searches that the individual information of the “viewer ID” and the “instruction action” constituting the “action response information 102” is the same and the information of the “instruction ID” is different. By searching for “response operation history” as a condition, other detection results detected by the motion sensor 23 based on an instruction of the same operation performed by the same viewer are searched and extracted.

  For example, the response operation comparison unit 26 shown in FIG. 1 includes the detection result (information of “response operation” constituting the “operation response information 102” (see FIG. 4)) detected by the motion sensor 23 and the response operation recording unit 25. Compared with other detection results (information of “response operation” constituting “operation response information 102”) searched and extracted by. The response motion comparison means 26 quantitatively grasps the difference (secondary information) in the detection results detected by the motion sensor 23 by comparing a plurality of “motion response information 102” with each other.

  For example, the viewer authentication means 27 shown in FIG. 1 has a predetermined standard (“authentication standard” (FIG. 1) that determines the difference (secondary information) in the response action quantitatively grasped by the response action comparison means 26 (See 3)). The viewer authentication means 27 includes the detection result lastly detected by the motion sensor 23 (“response action” information constituting the “action response information 102” (see FIG. 4)) (primary information) and the response action recording means 25. The difference (secondary information) from the average value of the other detection results (information of "response action" constituting "action response information 102") (primary information) retrieved and extracted by When it is recognized that it is within the range of the standard to be established (for example, based on the “certification standard”, the maximum difference in acceleration is within 1.2 G (1.2 times the gravitational acceleration on the earth) or less) Finally, the viewer who has performed the response operation related to the detection result detected by the motion sensor 23 is authenticated that the program providing entity of the audiovisual program is the viewer who provides the audiovisual program. The viewer authentication means 27 performs “viewer authentication (audiovisual terminal) 106a” (see FIG. 5) (tertiary information) when authenticating that the viewer who last responded is the viewer himself / herself. Output. The output “viewer authentication (audiovisual terminal) 106a” (tertiary information) is transmitted by the transmission means 29 to the audiovisual authentication system 40 (see FIG. 8) of the audiovisual authentication entity.

  With this configuration, the viewer of the audiovisual program can use the motion sensor to record the detection result detected by the motion sensor included in the audiovisual terminal operated by the viewer as a response operation history. The detected detection result can be recorded as a response operation history, and the detection result detected by the motion sensor can be searched and extracted under an arbitrary condition. Also, a response operation for comparing the detection result detected last by the motion sensor with other detection results other than the detection result detected last by the motion sensor in the response operation history recorded by the response operation recording means. The comparison means can quantitatively grasp the difference between the last response action performed by the viewer and the previous response action performed by the viewer. In addition, when the result of comparison by the response operation comparison unit is recognized that the detection result last detected by the motion sensor matches the other detection results included in the response operation history according to a predetermined standard The viewer is authenticated by the viewer authentication means for outputting the viewer authentication for authenticating the viewer as the viewer who is the target of the provision of the audiovisual program. It is possible to obtain the viewer authentication for authenticating that the program providing entity of the audiovisual program is the viewer who is the target of the audiovisual program according to the specified authentication standard. Further, the viewer authentication can be transmitted to the audiovisual authentication system possessed by the audiovisual authentication entity by a transmission means provided in the audiovisual terminal. Therefore, based on the viewer authentication, it is possible to obtain authentication that the viewer has viewed the audiovisual program by the audiovisual authentication subject.

  The audiovisual terminal according to the fifth aspect is the audiovisual terminal according to any one of the first to fourth aspects. For example, the operation instruction means 22 provided in the audiovisual terminal 20a shown in FIG. 20 provides the audiovisual program. The program providing entity requests the viewer to make a predetermined touch based on “touch instruction information” (not shown) specific to the audiovisual program that requests the viewer to make a predetermined touch at a timing specific to the audiovisual program. A touch screen detection means 35 for detecting a touch on the audiovisual terminal 20a performed by the viewer every time the touch is instructed by the operation instruction means 22 for transmission to the authentication subject; Reference numeral 24 designates “information about the viewer's touch” obtained from the detection result detected by the touch screen detection means 35 as a signal that can be transmitted by the transmission means 29. Configured.

  For example, the operation instruction means 22 provided in the audiovisual terminal 20a shown in FIG. 20 is similar to the operation instruction by the “operation instruction information 101” (see FIG. 3) described above. The viewer is instructed to make a touch based on “touch instruction information” (not shown) specific to the audiovisual program that requests the viewer to make a predetermined touch at the timing. The touch screen detection unit 35 provided in the audiovisual terminal 20a performs a predetermined touch on the audiovisual terminal 20a that is performed by the viewer to transmit to the audiovisual authentication entity every time the operation instruction unit 22 instructs the predetermined touch. To detect. Further, the signal converting means 24 included in the audiovisual terminal 20a obtains “information related to the viewer's touch” obtained from the detection result detected by the touch screen detecting means 35, similarly to the “information related to the viewer's response operation” described above. The signal is converted into a signal that can be transmitted by the transmission means 29.

  With this configuration, the viewer of the audiovisual program can make a touch unique to the audiovisual program in which the program providing entity that provides the audiovisual program requests the viewer to perform a predetermined touch at a timing specific to the audiovisual program. Based on the instruction information, the operation instruction means for instructing the viewer to perform the touch, the touch that is instructed by the operation instruction means for the touch that the program provider providing the audio-visual program requests the viewer. Can be grasped as instructions. In addition, the viewer performs the viewer every time the touch is instructed by the operation instruction means to transmit to the audio-visual authentication entity that authenticates that the viewer is viewing the audio-visual program normally. By the touch screen detection means for detecting the touch of the viewer, the viewer's touch performed by the viewer can be detected as detection by the touch screen detection means. In addition, the viewing detected by the touch screen detecting means is converted into a signal that can be transmitted by the transmitting means to information relating to the viewer's touch obtained from the detection result detected by the touch screen detecting means. The detection of the user's touch can be signaled into a signal that can be transmitted by the transmission means as information relating to the viewer's touch obtained from the detection result detected by the touch screen detection means. In addition, the information output from the audiovisual terminal is transmitted to the audiovisual authentication entity by transmission means for transmitting the information output from the audiovisual terminal to the audiovisual authentication system of the audiovisual authentication entity to obtain the authentication of viewing. can do.

  For this reason, for example, the viewer performs the instructed operation in response to the operation instruction by the operation instruction means and responds to the touch screen in response to the touch instruction by the operation instruction means. When it is easier or appropriate to respond by performing the instructed touch to the detection means in light of the situation of the viewer, the user selects to perform the touch on the touch screen detection means included in the audiovisual terminal. Can respond. For example, when the viewer is temporarily in a crowded place or the like, or because the viewer is in a library, etc., the user does not want to gather the attention of others by performing an action for the response In such a case, it is possible to respond silently by selectively performing the touch on the touch screen detecting means in response to the touch instruction. Therefore, based on the information about the viewer's touch obtained from the detection result detected by the touch screen detection means transmitted by the transmission means, the viewer by the audiovisual authentication subject has viewed the audiovisual program. You can get certification about that.

  In the audiovisual terminal according to any one of the first to fifth aspects, for example, the audiovisual terminal 20 shown in FIG. 1 can be provided as a portable terminal possessed by the viewer.

  For example, the audiovisual terminal 20 shown in FIG. 1 is particularly reduced in size and weight by using an electronic circuit integration technique. For this reason, a viewer who operates the audiovisual terminal 20 can easily operate by holding or holding the audiovisual terminal 20 with one hand.

  With this configuration, the viewer of the audiovisual program can determine the time and place where the audiovisual terminal is used by providing the audiovisual terminal operated by the viewer as a portable terminal possessed by the viewer. The audiovisual program can be viewed using more opportunities that the viewer has without being greatly limited in terms of conditions. In particular, when the viewer uses the audiovisual terminal to view the distance learning program and the distance education by the program providing entity providing the distance education program is performed, the viewer has more than the viewer has. The distance education can be performed using the opportunity. Further, since the viewing of the distance learning program by the viewer who is a student of the distance learning program can be objectively authenticated using the audiovisual authentication system possessed by the audiovisual authentication entity, the viewer and the viewer A program providing entity that provides a distance education program can preferably realize the distance education such as distance learning and self-study type education.

  Further, in the audiovisual terminal according to any one of the first to fifth aspects, for example, the reproduction means 21 included in the audiovisual terminal 20 shown in FIG. 1 is configured to receive and reproduce the broadcasted audiovisual program. can do.

  For example, the reproduction means 21 shown in FIG. 1 is an audiovisual transmission that is transmitted by a broadcast or satellite broadcast performed by a program providing entity of an audiovisual program via a broadcast communication satellite, a radio wave tower provided on the ground, or a wired communication cable. It has a tuner (not shown) that can receive a program and information broadcast of “operation instruction information 101” (see FIG. 3). For this reason, the received audiovisual program can be reproduced by the tuner included in the reproduction means 21 and presented to the viewer. In addition, the operation instruction unit 22 can instruct the viewer to perform an operation by transmitting the “operation instruction information 101” received by the tuner included in the reproduction unit 21 to the operation instruction unit 22.

  With this configuration, the viewer of the audiovisual program is configured so that the playback means provided in the audiovisual terminal operated by the viewer receives and plays the broadcasted audiovisual program. By using more opportunities that the viewer has, the broadcasted audiovisual program and the operation instruction information can be received and the audiovisual program can be viewed.

  In the audiovisual terminal according to any one of the first to fifth aspects, for example, the reproduction means 21 included in the audiovisual terminal 20 shown in FIG. 1 reproduces the audiovisual program recorded on the reproducible recording medium. Can be configured.

  For example, the reproducing means 21 shown in FIG. 1 includes a CD-R (Compact-Disc-Recordable), a DVD (Digital-Versatile-Disc), a magneto-optical disk (Magneto-Optical-disc), and a ROM (Read-Only-Memory). And a multimedia player (not shown) that can reproduce the audiovisual program provided by the program providing entity of the audiovisual program recorded in the electromagnetically or optically reproducible recording medium. In addition, information on “operation instruction information 101” (see FIG. 3) is also recorded and provided in advance on a reproducible recording medium by an audiovisual authentication entity. Therefore, the reproducing unit 21 reads “operation instruction information 101” from a recording medium that can be reproduced by the multimedia player included in the reproducing unit 21, and sends the “operation instruction information 101” from the reproducing unit 21 to the operation instruction unit 22. Can be handed over. Thereby, the operation instruction means 22 can instruct the viewer of the operation.

  With this configuration, the viewer of the audiovisual program is configured such that the playback means provided in the audiovisual terminal operated by the viewer plays back the audiovisual program recorded on the reproducible recording medium. The audio-visual program and the “operation instruction information” recorded on the reproducible recording medium can be reproduced and used. Therefore, the audiovisual program can be played back and viewed using more opportunities that the viewer has.

  Further, in the audiovisual terminal according to any one of the first to fifth aspects, for example, the reproduction means 21 included in the audiovisual terminal 20 shown in FIG. Can be configured.

  For example, the reproducing means 21 shown in FIG. 1 also has an information communication device (wireless LAN communication device (router)) that can be connected to a wide area network (WAN) (wire-area-network) by wireless communication or wired communication ( (Not shown). For this reason, the reproducing means 21 also uses the information communication device (wireless LAN communication device (router)) for the audiovisual program enabled to be transmitted by the audiovisual authentication system 40 (see FIG. 8) possessed by the audiovisual authentication entity through the telecommunication line. Can be used to reproduce the audiovisual program and present the audiovisual program to the viewer. Further, “operation instruction information 101” (see FIG. 3) can be obtained through the telecommunication line. In particular, the information communication device (wireless LAN communication device (router)) included in the playback means 21 is streamed (stream distribution) when the viewer can use the audiovisual terminal 20 by connecting it to a high-speed telecommunication network. By using information communication technology such as progressive download and the like, an audiovisual program that can be transmitted through a telecommunication line can be reproduced and presented to the viewer.

  With this configuration, the viewer of the audiovisual program is configured so that the playback means provided in the audiovisual terminal operated by the viewer plays back the audiovisual program that can be transmitted through the telecommunication line. Thus, the information of the audiovisual program and the operation instruction information that can be transmitted through the telecommunication line can be obtained. Therefore, the audiovisual program can be played back and viewed using more opportunities that the viewer has.

  The audiovisual terminal according to the sixth aspect is the audiovisual terminal according to any one of the first to fifth aspects. For example, the transmission means 29 provided in the audiovisual terminal 20 shown in FIG. The transmission is performed while the program is being viewed.

  For example, the transmission means 29 shown in FIG. 1 includes information (primary information, secondary information, and tertiary information) output from the audiovisual terminal 20 at any time even when the audiovisual program is being viewed by the viewer. It can be transmitted to the audiovisual authentication system 40 (see FIG. 8). For this reason, when the audiovisual terminal 20 can perform bidirectional high-speed information communication using a high-speed telecommunication network, it is particularly preferable that the transmission means 29 is an audiovisual authentication system possessed by an audiovisual authentication entity at any time. Information (primary information, secondary information, tertiary information) output by the audiovisual terminal 20 can be transmitted to 40 (see FIG. 8).

  With this configuration, the viewer of the audiovisual program is configured such that the transmission means provided in the audiovisual terminal operated by the viewer performs the transmission while the audiovisual program is viewed by the viewer. Thus, the information output from the audiovisual terminal can be transmitted to the audiovisual authentication entity at any time. Therefore, at the same time as viewing the audiovisual program, it is possible to obtain authentication that the viewer has viewed the audiovisual program by the audiovisual authentication entity.

  The audiovisual terminal according to the seventh aspect is the audiovisual terminal according to any one of the first to fifth aspects. For example, the transmission means 29 provided in the audiovisual terminal 20 shown in FIG. The transmission is performed after the reproduction of the program is completed.

  For example, there are cases where the audiovisual terminal 20 shown in FIG. 1 cannot be connected to a high-speed telecommunication network. Specifically, this is a case where the audiovisual terminal 20 is connected to a narrow band, so that the audiovisual authentication entity cannot view the audiovisual program using streaming (stream distribution) performed in the WAN. Even in such a case, the viewer can view the audiovisual program transmitted via the broadcast or reproducible recording medium by the audiovisual terminal 20.

  For example, the recording means 32 included in the audiovisual terminal 20 shown in FIG. 1 outputs information (primary information, secondary information, and tertiary information) output by the audiovisual terminal 20 while the viewer is watching the audiovisual program. The audio / visual authentication system 40 (see FIG. 8) possessed by the audio / visual authentication main body is recorded at any time without being transmitted.

  In addition, after the playback of the audiovisual program is completed, the viewer records the audiovisual terminal 20 shown in FIG. 1 in accordance with a manual operation by the viewer using the transmission means 29 in a state where the audiovisual terminal 20 is connected to a high-speed telecommunication network having sufficient communication capability. The information (primary information, secondary information, and tertiary information) output by the audiovisual terminal 20 recorded in the means 32 is collectively collected in the audiovisual authentication system 40 (see FIG. 8) possessed by the audiovisual authentication entity. Send at times.

  With this configuration, the viewer of the audiovisual program is configured such that the transmission means provided in the audiovisual terminal operated by the viewer performs the transmission after the reproduction of the audiovisual program by the viewer is completed. Thus, even when the audiovisual terminal cannot be connected to the high-speed telecommunications network, after the viewer reproduces and views the audiovisual program on the audiovisual terminal, the information output from the audiovisual terminal by the transmission means is displayed. , And can be sent to the audiovisual authentication entity at once.

  The program of the eighth mode is a program for controlling the audiovisual terminal 20 (see FIG. 1) operated by the viewer of the audiovisual program, for example, as shown in FIG. 7, and reproduces the audiovisual program.

A process for detecting the response action of the viewer performed by the viewer with the motion sensor 23; a signal capable of transmitting “information about the response action of the viewer” obtained from the detection result detected by the motion sensor Process and for signaling; a parallax information hearing terminal output is configured to perform a process of transmitting the audiovisual authentication system having the authentication entity of the visual hearing in order to obtain a certification of the view.

  For example, if the control program shown in FIG. 7 includes main processing for controlling the audiovisual terminal 20 (see FIG. 1), the control program reproduces the audiovisual program using the reproduction means 21 (see FIG. 1) (step M01). ). Further, based on the “operation instruction information 101” (see FIG. 3), the operation is instructed to the viewer using the operation instruction means 22 (see FIG. 1) (step M02). Further, the response operation of the viewer is detected using the motion sensor 23 (see FIG. 1) (step M03). Further, the detection by the motion sensor 23 is converted into a signal by using the signal converting means 24 (see FIG. 1) and acquired as a detection result (primary information). (Step M04). In addition, based on the detection result (primary information) acquired using the signal generation means 24, “operation response information 102” (see FIG. 4) is created and signaled to a signal that can be transmitted by the transmission means 29 ( Step M05). Also, the “operation response information 102” is transmitted to the audiovisual authentication system 40 (see FIG. 8) possessed by the audiovisual authentication entity using the transmission means 29 (see FIG. 1) (step M06).

  By configuring in this way, the program can reproduce and present the audiovisual program to the viewer by appropriately controlling the audiovisual terminal operated by the viewer and reproducing the audiovisual program. . In addition, the program providing entity that provides the audiovisual program instructs the viewer to perform the operation based on the operation instruction information specific to the audiovisual program that requests the viewer to perform a predetermined operation at a timing specific to the audiovisual program. Through this process, the viewer can be instructed to perform a predetermined operation requested by the program provider. In addition, a response action of the viewer performed by the viewer every time the operation is instructed to transmit to the audio-visual authentication entity that authenticates that the viewer is normally viewing the audio-visual program. By the processing detected by the sensor, a response action performed by the viewer using the motion sensor can be detected. Further, the viewer's motion response obtained from the detection result detected by the motion sensor by processing the information related to the viewer's response motion obtained from the detection result detected by the motion sensor into a signal that can be transmitted. Can be acquired or created as a signal that can be transmitted to the audiovisual authentication entity. In addition, by the process of transmitting the information output from the audiovisual terminal to the audiovisual authentication system possessed by the audiovisual authentication entity to obtain the authentication of viewing, the audiovisual authentication possessed by the audiovisual authentication entity is output from the audiovisual terminal. Can be sent to the authentication system. For this reason, it is possible to obtain authentication that the viewer has viewed the audiovisual program by the audiovisual authentication subject based on information on the response operation of the viewer obtained from the detection result detected by the motion sensor. it can.

  Also, the audiovisual authentication system of the ninth aspect is an audiovisual authentication system 40 that authenticates, for example, that the viewer of the audiovisual program shown in FIG. 8 is normally viewing the audiovisual program; Program transmitting means 41 for transmitting to the audiovisual terminal 20 (see FIG. 1) operated by the viewer in response to a request from the viewer; and a program providing entity that provides the audiovisual program at the timing unique to the audiovisual program Operation instruction information creating means 42 for creating “operation instruction information 101” (refer to FIG. 3) unique to the audiovisual program, which is made up of information requesting a predetermined operation from the viewer; and the audiovisual terminal 20 operated by the viewer “ Operation instruction information transmitting means 43 for transmitting the operation instruction information 101; and an audiovisual terminal 20 operated by the viewer, which is sent back to convey that the viewer is normally viewing the audiovisual program.

  For example, the audiovisual authentication system 40 shown in FIG. 8 is a dedicated server possessed by an audiovisual authentication entity connected to a WAN (Wide-Area-Network). The audiovisual authentication system 40 has a dedicated “information provision homepage” (not shown) created in the HTML language (HyperText-Markup-Language) that can provide audiovisual program information to the viewer. The audiovisual authentication system 40 receives the “program transmission request 100” (see FIG. 10) from the viewer through a dedicated “information providing homepage”. The audiovisual authentication system 40 also determines whether or not the viewer who has transmitted the “program transmission request 100” is a viewer who provides the audiovisual program as a program providing entity that provides the audiovisual program. Present and confirm the “provided homepage (viewer simple authentication page)”. The viewer himself / herself has both the “viewer ID” (see FIG. 3) issued by the audiovisual authentication entity in advance and the “password” (viewer simple authentication information) (not shown) unique to the “viewer ID”. Have been notified. The viewer inputs both the “viewer ID” and the “password” information in an appropriate input field of a dedicated “information providing homepage” published by the audiovisual authentication system 40.

  For example, the program transmission means 41 shown in FIG. 8 is the viewer himself / herself by the audiovisual authentication system 40 (see FIG. 8) simply using the “viewer ID” (see FIG. 3) and the “password” (not shown). A streaming server connected to the WAN, which transmits the audiovisual program to the audiovisual terminal 20 (see FIG. 1) operated by the viewer based on the “program transmission request 100” (see FIG. 10) from the viewer who has been authenticated. It is. The audiovisual program information is recorded in the program database 51 connected to the program transmission means 41.

Specifically, for example, the response action recording unit 46 searches and extracts other detection results (primary information) based on instructions for the same action performed by the same viewer from the “response action history”.

  More specifically, for example, the detection result (primary information) detected by the motion sensor 23 (see FIG. 1) is received by the receiving means 44 shown in FIG. 8 and the received information processing means 45 processes the information. Are recorded in the response operation history database 52 as “response operation” information constituting “operation response information 102” (see FIG. 4). Further, as the information constituting the “operation response information 102”, “operation instruction information 101” (see FIG. 3) corresponding to the “operation response information 102” is recorded, and “operation instruction information 101” is recorded. As information constituting “”, information of “viewer ID”, “instruction operation”, and “instruction ID” is recorded. For this reason, the response action recording means 25 searches the “response action history” using the search condition that “viewer ID” and “instruction action” are the same and the “instruction ID” is different, thereby making the same It is possible to search and extract other detection results (information of “response operation” constituting “operation response information 102”) (primary information) based on the instruction of the same operation performed by the viewer.

  For example, the response operation comparison unit 47 shown in FIG. 8 is similar to the response operation comparison unit 26 (see FIG. 1) provided in the audiovisual terminal 20 (see FIG. 1) operated by the viewer, as described above. ) Is the last detected result (information of “response operation” constituting “operation response information 102” (see FIG. 4)) (primary information) and other information retrieved and extracted by the response operation recording means 46 The detection result (information of “response operation” constituting “operation response information 102”) (primary information) is compared. The response motion comparison means 47 quantitatively compares the difference (secondary information) in the detection result (primary information) detected by the motion sensor 23 (see FIG. 1) by comparing a plurality of “motion response information 102” with each other. Can grasp.

  For example, the viewer authentication means 48 shown in FIG. 8 is quantified by the response operation comparison means 47 in the same manner as the viewer authentication means 27 (see FIG. 1) provided in the audiovisual terminal 20 (see FIG. 1) operated by the viewer. It is an authentication device that evaluates a difference (secondary information) of “response operation” (primary information) that is grasped in accordance with predetermined criteria determined by an audiovisual authentication subject. The viewer authentication means 48 detects the detection result lastly detected by the motion sensor 23 (see FIG. 1) (“response operation” information constituting the “operation response information 102” (see FIG. 4)) (primary information) and The “response operation” (primary information) with other detection results (information of “response operation” constituting “operation response information 102”) (primary information) retrieved and extracted by the response operation recording means 46 When it is recognized that the difference (secondary information) is within the range defined by the audiovisual authentication subject (for example, based on the “authentication standard”, the “acceleration difference is 1.2 G or less maximum”) Finally, the viewer who performs the response operation is authenticated as the viewer who provides the audiovisual program. When the viewer authenticating means 48 authenticates that the viewer who last responded is the viewer himself / herself, “viewer authentication (audiovisual authentication system) 106b” (see FIG. 5) (tertiary information) Is output. The output “viewer authentication (audiovisual authentication system) 106b” is recorded as information constituting the “authentication record 107” (see FIG. 5) by the authentication recording means 53.

  With this configuration, the audiovisual authentication entity can be detected by the motion sensor included in the audiovisual terminal operated by the viewer received by the reception unit included in the audiovisual authentication system included in the audiovisual authentication entity. Record the detection result detected by the motion sensor as a response operation history by the response operation recording means for recording the result as a response operation history, and search and extract the detection result detected by the motion sensor under an arbitrary condition. Can do. Further, a response operation comparison for comparing the detection result last detected by the motion sensor with other detection results excluding the detection result last detected by the motion sensor in the response operation history recorded by the response operation recording means. By the means, it is possible to quantitatively grasp the difference between the response operation last performed by the viewer and the response operation previously performed by the viewer. In addition, when the result of comparison by the response operation comparison unit is recognized that the detection result last detected by the motion sensor matches the other detection results included in the response operation history according to a predetermined standard The viewer is authenticated by the viewer authentication means for outputting the viewer authentication for authenticating the viewer as the viewer who is the target of the provision of the audiovisual program. It is possible to obtain viewer authentication for authenticating that the program providing entity of the audiovisual program is the target audience of the audiovisual program based on the authentication standard that is defined. Further, the viewer authentication can be recorded as information constituting the authentication record by an authentication recording means provided in the audiovisual authentication system. For this reason, it is possible to authenticate that the viewer has viewed the audiovisual program based on the viewer authentication.

The received information processing means 45 included in the audiovisual authentication system 40 is similar to the above-mentioned “information related to the viewer's response operation”, and the “viewer has viewed the audiovisual program” based on the received “information related to the viewer's touch”. It is processed into “information to authenticate”.

  With this configuration, the audiovisual authentication entity is unique to the audiovisual program that includes information that the program providing entity that provides the audiovisual program requests the viewer to make a predetermined touch at a timing specific to the audiovisual program. The touch instruction information for requesting the viewer to make the touch can be created by the operation instruction information creating means for creating the touch instruction information. The touch instruction information can be transmitted to the audiovisual terminal operated by the viewer by the operation instruction information transmitting means for transmitting the touch instruction information to the audiovisual terminal operated by the viewer. The detection result detected by the touch screen detecting means provided in the audiovisual terminal output by the audiovisual terminal operated by the viewer, which is sent back to convey that the viewer is normally viewing the audiovisual program. Receiving information related to the viewer's touch obtained from the detection result detected by the touch screen detecting means included in the audiovisual terminal operated by the viewer. Can do. Further, the received information processing means for processing the received information related to the viewer's touch to information for authenticating that the viewer has viewed the audio-visual program is detected by the touch screen detecting means included in the received audio-visual terminal. The information related to the viewer's touch can be processed to obtain information for authenticating that the viewer has viewed the audiovisual program. Therefore, the audiovisual authentication system can authenticate that the viewer has viewed the audiovisual program.

  Further, in the program of the fifteenth aspect, for example, as shown in FIG. 10, the viewer of the audiovisual program used to control the audiovisual authentication system 40 (see FIG. 8) normally views the audiovisual program. A program for controlling an audiovisual authentication system that authenticates the audiovisual information; a process for transmitting the audiovisual program to the audiovisual terminal 20 (see FIG. 1) operated by the viewer in response to a request from the viewer; Processing for creating “operation instruction information 101” (refer to FIG. 3) unique to the audiovisual program, which includes information requesting the viewer to perform a predetermined action at a timing specific to the audiovisual program, by the program providing entity providing the program A process of transmitting “operation instruction information 101” to the audiovisual terminal 20 operated by the viewer; and a reply for transmitting that the viewer is normally viewing the audiovisual program, A process of receiving “information related to the response operation of the viewer” obtained from the detection result detected by the motion sensor 23 (see FIG. 1) provided in the audiovisual terminal 20 output by the audiovisual terminal 20 operated by the listener; Processing the “information regarding the response operation of the viewer” into “information for authenticating that the viewer has viewed the audiovisual program”; analyzing the received “information regarding the response operation of the viewer”; Processing for identifying the viewer's response operation; processing for recording “information for authenticating that the viewer has viewed the audiovisual program” output by the audiovisual authentication system in order to authenticate the viewing; It is comprised so that it may perform.

  For example, if the control program shown in FIG. 10 is a main process for controlling the audiovisual authentication system 40 (see FIG. 8), the control program transmits the program transmission means 41 (in response to the “program transmission request 100” from the viewer). 8), the audiovisual program recorded in the program database 51 (see FIG. 8) is transmitted to the audiovisual terminal 20 (see FIG. 1) operated by the viewer (step S01). Further, the operation instruction information includes “operation instruction information 101” (see FIG. 3) unique to the audiovisual program, which is composed of information requesting a predetermined operation from the viewer at a timing unique to the audiovisual program. It creates using the creation means 42 (refer FIG. 8) (step S02). Further, the “operation instruction information 101” is transmitted to the viewer using the operation instruction information transmission means 43 (see FIG. 8) (step S03). In addition, “information related to the response operation of the viewer” obtained from the detection result detected by the motion sensor 23 (see FIG. 1) provided in the audiovisual terminal 20 output by the audiovisual terminal 20 operated by the viewer to whom the viewer replies is received. It receives using the means 44 (refer FIG. 8) (step S04). Further, “information related to the viewer's response operation” (primary information, secondary information, and tertiary information) obtained from the detection result (primary information) detected by the received motion sensor 23 is received information processing means 45 (FIG. 8) is processed into “information for authenticating that the viewer has viewed the audiovisual program” (primary information, secondary information, and tertiary information) in accordance with the “authentication standard” defined by the audiovisual authentication entity. Output. At this time, the “response information of the viewer” received using the motion analysis specifying unit 45a (see FIG. 9) of the reception information processing means 45 is analyzed to specify the viewer's response operation. (Step S05). Further, “information for authenticating that the viewer has viewed the audiovisual program” output by the audiovisual authentication system is recorded using the authentication recording means 53 (see FIG. 8) (step S11).

  With this configuration, the program appropriately controls the audiovisual authentication system of the audiovisual authentication entity, and transmits the audiovisual program to the audiovisual terminal operated by the viewer in response to the viewer's request. The audiovisual program can be transmitted to the audiovisual terminal operated by the viewer. In addition, the program providing entity that provides the audio-visual program generates operation instruction information unique to the audio-visual program, which includes information requesting the viewer to perform a predetermined operation at a timing specific to the audio-visual program. The operation instruction information for requesting the operation to the person can be created. Further, the operation instruction information can be transmitted to the audiovisual terminal operated by the viewer by the process of transmitting the operation instruction information to the audiovisual terminal operated by the viewer. In addition, it is obtained from a detection result detected by a motion sensor provided in the audiovisual terminal that is output by the audiovisual terminal operated by the viewer, which is sent back to convey that the viewer is normally viewing the audiovisual program. By the process of receiving the information related to the response operation of the viewer, the information related to the response operation of the viewer obtained from the detection result detected by the motion sensor included in the audiovisual terminal operated by the viewer can be received. . Further, by processing the received information relating to the response operation of the viewer into information for authenticating that the viewer has viewed the audiovisual program, the viewer can check the authentication criteria set by the audiovisual authentication entity. An authentication result for authenticating that the audiovisual program has been viewed can be obtained. In addition, by analyzing the received information on the response operation of the viewer and specifying the response operation of the viewer, the motion of the audiovisual terminal or the viewer is determined based on the detection result detected by the received motion sensor. By specifying the response operation, it is possible to specify the response operation of the viewer who operates the audiovisual terminal and to realize information processing by the received information processing means. In addition, in order to authenticate the viewing, the viewer views the audiovisual program by a process of recording information for authenticating that the viewer has viewed the audiovisual program output from the audiovisual authentication system. This information can be recorded as information constituting the authentication record recorded by the authentication recording means included in the audiovisual authentication system. Therefore, it is possible to authenticate that the viewer has viewed the audiovisual program based on the authentication record.

  The audiovisual terminal of the sixteenth aspect is, for example, an audiovisual terminal 60 operated by a viewer of the audiovisual program shown in FIG. 11; reproduction means 61 for reproducing the audiovisual program; reproduced by a reproduction operation by the viewer The “reproduction authentication point 110” (see FIGS. 12 and 13), which is a signal provided in the audiovisual program at predetermined time intervals, is detected from the audiovisual program by the program providing entity that provides the audiovisual program. A reproduction detection means 62 for performing; a clock 63 for outputting "the time when the reproduction authentication point 110 is detected" by the reproduction detection means 62; and an audiovisual for authenticating that the viewer is normally viewing the audiovisual program. In order to communicate to the authentication subject, the audiovisual authentication subject has the detected “reproduction authentication point 110” and “the time when the reproduction authentication point 110 is detected”. Objective and transmitting means 65 for transmitting to the authentication system 80 (see FIG. 16).

  For example, the reproducing means 61 shown in FIG. 11 presents the audiovisual program provided by the program providing entity to the viewer who views the audiovisual program with video and audio. In addition, the reproducing means 61 is a recording medium that can be broadcasted or reproduced or an information transmission medium of a telecommunication line as in the reproducing means 21 (see FIG. 1) included in the audiovisual terminal 20 (see FIG. 1). The audiovisual program transmitted through the network can also be provided to the viewer. In addition, in the audiovisual program information provided by the program providing entity, the program progress time of the audiovisual program provided at predetermined time intervals by the program providing entity is defined for the purpose of confirming the viewing of the audiovisual program by the viewer. The “reproduction authentication point 110” (see FIG. 12), which is a signal to be transmitted, is provided at each position on the time axis in the audiovisual program (see FIG. 13), and the audiovisual program is provided to the viewer. Further, the period information provided with the “reproduction authentication point 110” is encrypted as “period information” which is the information constituting the “reproduction authentication point 110” by the audiovisual authentication subject, and the “reproduction authentication point 110” is encrypted. Is recorded in the information.

  For example, the reproduction detecting unit 62 shown in FIG. 11 includes an audiovisual program provided at predetermined time intervals in the audiovisual program by the program providing entity that provides the audiovisual program from the information of the audiovisual program reproduced by the reproducing unit 61. The “reproduction authentication point 110” (see FIG. 12), which is a signal that defines the program progress time, is detected.

  For example, the clock 63 shown in FIG. 11 outputs “the time when the reproduction authentication point 110 (see FIGS. 12 and 13) is detected” by the reproduction detection means 62. The time output by the clock 63 is recorded in the information of “reproduction authentication point 110” as information of “detection time” (see FIG. 12) that is information constituting “reproduction authentication point 110”.

  For example, the transmission means 65 shown in FIG. 11 includes an audiovisual authentication system 80 (see FIG. 16) in which the audiovisual authentication entity has “reproduction authentication point 110” (see FIGS. 12 and 13) and “time when the reproduction authentication point 110 is detected”. ). Therefore, the audiovisual authentication entity that has received the “reproduction authentication point 110” and “the time when the reproduction authentication point 110 is detected” reproduces the time when the audiovisual program is reproduced by the audiovisual terminal 60 operated by the viewer and the audiovisual program. The program playback time based on the recorded time can be grasped.

  With this configuration, the viewer of the audiovisual program can reproduce and view the audiovisual program by the reproduction means that reproduces the audiovisual program provided in the audiovisual terminal operated by the viewer. In addition, a reproduction authentication point, which is a signal provided in the audiovisual program at predetermined time intervals, is detected by the program providing entity providing the audiovisual program from the audiovisual program reproduced by the reproduction operation by the viewer The reproduction authentication means can detect the reproduction authentication point from the information of the audiovisual program. In addition, by the clock that outputs the time when the reproduction authentication point is detected by the reproduction detection means, the information of the time when the reproduction authentication point is detected is output and the information of the time when the reproduction authentication point is detected is viewed. Can be used to obtain authentication. In addition, in order to transmit to the audio-visual authentication entity that authenticates that the viewer is normally viewing the audio-visual program, the detected audio reproduction point and the time when the reproduction authentication point is detected are By the transmission means for transmitting to the audiovisual authentication system possessed by the authentication subject, the detected reproduction authentication point and the time when the reproduction authentication point was detected can be transmitted to the audiovisual authentication system possessed by the audiovisual authentication subject. Therefore, it is possible to obtain authentication that the viewer has viewed the audiovisual program by the audiovisual authentication entity.

  Also, the audiovisual terminal of the seventeenth aspect is the audiovisual terminal of the sixteenth aspect, for example, from the time when two or more “reproduction authentication points 110 (see FIGS. 12 and 13) shown in FIG. 11” are detected. Viewing analysis means 66 for analyzing and outputting “reproduction operation history” by the user; the transmission means 65 includes “reproduction operation history (audiovisual terminal) 111a” (see FIG. 14) output by the viewing analysis means 66. In order to authenticate the viewing, it is further configured to transmit to the audiovisual authentication system 80 (see FIG. 16) possessed by the audiovisual authentication entity.

  For example, the viewing analysis means 66 shown in FIG. 11 has a “playback operation history” that is a history of playback operations of audiovisual programs by viewers from two or more “time when playback authentication points 110 (see FIGS. 12 and 13) are detected”. "Is analyzed and output. The “reproduction authentication point 110” is provided at a fixed period (on each point 110a shown in FIG. 13) with respect to the program progress time by the audiovisual authentication entity based on the determination of the program providing entity, The point 110 "records the program playback time (" detection time ") (see FIG. 12) output by the clock 63 as a result of viewing the audiovisual program by the viewer.

  For this reason, the viewing analysis means 66 refers to the “period information” and the “detection time”, which are individual information constituting the “reproduction authentication point 110” (see FIG. 12), thereby determining the program progress time and the program reproduction time. Can be compared. Also, the viewing analysis means 66 can grasp the playback speed of the audiovisual program by the viewer by comparing the program progress time and the program playback time. In this way, the viewing analysis means 66 can grasp the time at which a specific playback portion of the audiovisual program provided with the “playback authentication point 110” is played back by the playback operation together with the program progress time. By comparing the program progress time and the program playback time, the playback speed at which the viewer played back the audiovisual program can be calculated as the “playback operation history”.

  Further, for example, the history of the playback operation by the viewer analyzed by the viewing analysis unit 66 shown in FIG. 11 is output as “playback operation history (audiovisual terminal) 111a” (see FIG. 14). Further, the transmission means 65 transmits the “playback operation history (audiovisual terminal) 111a” to the audiovisual authentication system 80 (see FIG. 16) possessed by the audiovisual authentication entity.

  With this configuration, the viewer of the audiovisual program analyzes the playback operation history by the viewer from the time when the two or more playback authentication points included in the audiovisual terminal operated by the viewer are detected. The reproduction operation history by the viewer can be output and obtained by the viewing analysis means for outputting. The transmission means included in the audiovisual terminal is configured to further transmit the reproduction operation history output by the viewing analysis means to the audiovisual authentication system possessed by the audiovisual authentication subject in order to authenticate the viewing. Thus, the reproduction operation history can be transmitted to the audiovisual authentication system possessed by the audiovisual authentication entity. Therefore, it is possible to obtain authentication that the viewer has viewed the audiovisual program by the audiovisual authentication entity.

  In addition, the audiovisual terminal of the eighteenth aspect is the audiovisual terminal of the seventeenth aspect. For example, the audiovisual terminal 60 shown in FIG. 11 is based on the “playback operation history (audiovisual terminal) 111a” (see FIG. 14). "Viewing authentication (audiovisual terminal) 114a" (based on the "playback operation history (audiovisual terminal) 111a" that authenticates that the viewer has viewed the audiovisual program for a predetermined time at a reproduction speed within a predetermined range ( 14 includes a viewing authentication unit 67 that outputs “viewing authentication (audiovisual terminal) 114a” based on the “playback operation history (audiovisual terminal) 111a” output by the viewing authentication unit 67. Further, it is configured to transmit to the audiovisual authentication system 80 (see FIG. 16) possessed by the audiovisual authentication entity.

  For example, the viewing authentication means 67 shown in FIG. 11 is based on the “playback operation history (audiovisual terminal) 111a” (see FIG. 14) output by the viewing analysis means 66, and the viewer falls within a predetermined range determined by the audiovisual authentication entity. "Reproduction operation history (audiovisual terminal) 111a" for authenticating that the audiovisual program has been viewed for a predetermined time (for example, "60 minutes or more") at the reproduction speed (for example, "reproduction speed less than double speed"). "Viewing authentication (audiovisual terminal) 114a" (see FIG. 14) is output. Further, the transmission means 65 has an audiovisual authentication system 80 (see FIG. 16) in which the audiovisual authentication entity has “viewing authentication (audiovisual terminal) 114a” based on the “playback operation history (audiovisual terminal) 111a” output by the viewing authentication means 67. Send it to

  With this configuration, a viewer of an audiovisual program can perform the viewer for a predetermined time based on the playback operation history provided in the audiovisual terminal operated by the viewer at a playback speed within a predetermined range. The viewing authentication unit that outputs the viewing authentication based on the reproduction operation history for authenticating that the audiovisual program has been viewed can be obtained by outputting the viewing authentication based on the reproduction operation history. In addition, the transmission unit is configured to further transmit the viewing authentication based on the playback operation history output by the viewing authentication unit to the audiovisual authentication system possessed by the audiovisual authentication entity, so that the playback operation is performed. The viewing authentication based on the history can be transmitted to the audiovisual authentication system of the audiovisual authentication entity. Therefore, based on the viewing authentication based on the reproduction operation history, it is possible to obtain authentication that the viewer has viewed the audiovisual program by the audiovisual authentication subject.

  In the audiovisual terminal according to any one of the sixteenth to eighteenth aspects, for example, the audiovisual terminal 60 shown in FIG. 11 can be provided as a portable terminal possessed by the viewer.

  For example, the audiovisual terminal 60 shown in FIG. 11 includes a reproduction unit 61, a reproduction detection unit 62, a clock 63, a recording unit 64, a transmission unit 65, a viewing analysis unit 66, a viewing authentication unit 67, and a microprocessor that controls these devices. Although it is a high-function audio-visual terminal equipped with (MPU) 70, it is particularly reduced in size and weight by using electronic circuit integration technology. For this reason, a viewer who operates the audiovisual terminal 60 can easily operate by grasping or holding the audiovisual terminal 60 with one hand.

  With this configuration, the viewer of the audiovisual program can use the audiovisual terminal operated by the viewer as a portable terminal possessed by the viewer, so that the time and place where the audiovisual terminal is used, etc. The audio-visual program can be viewed using more opportunities that the viewer has without being greatly restricted. In particular, when the viewer uses the audiovisual terminal to view the distance learning program and the distance education by the program providing entity providing the distance education program is performed, the viewer has more than the viewer has. The distance education can be performed using the opportunity. In addition, viewing of the distance learning program by the viewer who is a student of the distance learning program can be objectively authenticated using the audiovisual authentication system possessed by the audiovisual authentication entity. The program provider that provides the educational program can preferably realize the distance education such as distance learning and self-study type education.

  The audiovisual terminal according to the nineteenth aspect is the audiovisual terminal according to any one of the sixteenth to eighteenth aspects. For example, the audiovisual terminal 60 (see FIG. 11) has the function of the audiovisual terminal 20 (see FIG. 1). The audiovisual terminal 60a shown in FIG. 18 operated by the viewer of the incorporated audiovisual program; the program providing entity that provides the audiovisual program requests a predetermined operation from the viewer at a timing specific to the audiovisual program. Based on the “operation instruction information 101” (see FIG. 3) unique to the audiovisual program, operation instruction means 22 (see FIG. 1) for instructing the viewer to perform the operation; and the viewer normally views the audiovisual program A motion set that detects the viewer's response action performed by the viewer each time the operation is instructed by the operation instruction means 22 (see FIG. 1) to transmit to the audio-visual authentication subject that authenticates that A signal 23 that converts the “information related to the viewer's response operation” obtained from the detection result detected by the motion sensor 23 into a signal that can be transmitted by the transmission means 65 (see FIG. 11). Means 24 (see FIG. 1); the transmitting means 65 transmits the information output from the audiovisual terminal 60a to the audiovisual authentication system 80a (see FIG. 19) possessed by the audiovisual authentication subject in order to obtain the viewing authentication. Is configured to do.

  For example, the audiovisual terminal 60a shown in FIG. 18 in which the function of the audiovisual terminal 20 (see FIG. 1) is incorporated into the audiovisual terminal 60 (see FIG. 11) can be configured. In this case, the audio-visual authentication subject can make the audio-visual program viewer play and view the audio-visual program using the audio-visual terminal 60a in which the function of the audio-visual terminal 20 is incorporated in the audio-visual terminal 60. Strict viewing authentication by the audiovisual authentication entity can be performed without frequently requesting a predetermined operation.

  Specifically, when the viewer uses the audiovisual terminal 60a shown in FIG. 18, the audiovisual authentication entity does not frequently request the viewer to perform a predetermined operation, but the “reproduction authentication point 110” (FIG. 12, see FIG. 13), it is possible to authenticate that the viewer is playing the audiovisual program. For this reason, the audio-visual authentication subject does not need to frequently request a response operation from the viewer to authenticate the viewing. For example, when the viewer views the audiovisual program using the audiovisual terminal 60a, the audiovisual authentication entity determines the number of times of viewing authentication performed by requesting a predetermined operation from the viewer, the beginning of the audiovisual program, the audiovisual program. It is possible to reduce the number of times about three times at the center of the program progress time and the end of the audiovisual program.

  On the other hand, when the viewer uses the audiovisual terminal 60a shown in FIG. 18, the audiovisual authentication entity not only performs viewing authentication using the “reproduction authentication point 110” (see FIGS. 12 and 13). Since the viewer can be requested to perform a predetermined operation for viewing authentication, the viewing can be performed more strictly compared to the viewing authentication in which only the viewing authentication using the “reproduction authentication point 110” is performed. Can be authenticated. In other words, it is possible to detect a case where the viewer has left the audiovisual terminal activated. The case where the parts or functions of the first aspect are incorporated has been described above, but the parts or functions of the second to seventh aspects may be incorporated, respectively.

  With this configuration, the audiovisual authentication entity can perform strict authentication of the viewing by the audiovisual authentication entity without frequently requesting the viewer for a predetermined operation. That is, since the audiovisual terminal 60a shown in FIG. 18 has the function of the audiovisual terminal 60 (see FIG. 11), even if the frequency of operation instructions is low, the “reproduction authentication point 110” (see FIGS. 12 and 13). It can be used to authenticate viewing from moment to moment. Therefore, the viewer does not need to frequently perform a response operation that can hinder viewing to some extent during program viewing. Further, since there is a function of the audiovisual terminal 20 (see FIG. 1), it can be authenticated that there has been no act of leaving the audiovisual terminal in operation. Such a synergistic effect can be enjoyed.

  The program of the twentieth aspect is a program for controlling the audiovisual terminal 60 (see FIG. 11) operated by the viewer of the audiovisual program, for example, as shown in FIG. 15; A process of reproducing and presenting in accordance with an operation of the audiovisual terminal 60 by the viewer; a predetermined program within the audiovisual program by the program providing entity providing the audiovisual program from the audiovisual programs reproduced by the reproduction operation of the viewer Processing for detecting “reproduction authentication point 110” (see FIGS. 12 and 13), which is a signal provided at time intervals; processing for outputting “time when reproduction authentication point 110 is detected”; In order to communicate to the audio-visual authentication entity that authenticates that the audio-visual program is being viewed normally, the detected “reproduction authentication point 110” and “reproduction authentication point 11” There has been configured to perform a process of transmitting the audiovisual authentication system 80 (see FIG. 16) having the authentication entity of the detected time "the parallax hearing.

  For example, if the control program shown in FIG. 15 is a main process for controlling the audiovisual terminal 60 (see FIG. 11), the control program uses the reproduction means 61 (see FIG. 11) in accordance with the operation of the viewer's audiovisual terminal 60. The audiovisual program is reproduced and presented to the viewer (step N01). Further, “reproduction authentication point 110” which is a signal provided at predetermined time intervals in the audiovisual program by the program providing entity that provides the audiovisual program from among the audiovisual programs reproduced by the reproduction operation by the viewer (FIG. 12). , (See FIG. 13) is detected using the reproduction detection means 62 (see FIG. 11) (step N02). In addition, using the clock 63 (see FIG. 11), the reproduction detecting means 62 outputs “the time when the reproduction authentication point 110 is detected” (step N03). In addition, the “reproduction authentication point 110” detected by the reproduction detecting means 62 and the reproduction output by the clock 63 are transmitted to the audiovisual authentication entity that authenticates that the viewer is viewing the audiovisual program normally. The detecting means 62 transmits “the time when the reproduction authentication point 110 is detected” to the audiovisual authentication system 80 (see FIG. 16) of the audiovisual authentication entity using the transmitting means 65 (see FIG. 11) (step N04).

  With this configuration, the program appropriately controls the audiovisual terminal operated by the viewer of the audiovisual program, and reproduces and presents the audiovisual program according to the operation of the audiovisual terminal by the viewer. The audiovisual program can be reproduced and presented to the viewer in accordance with the operation by the viewer. In addition, a reproduction authentication point, which is a signal provided in the audiovisual program at predetermined time intervals, is detected by the program providing entity that provides the audiovisual program from the audiovisual program reproduced by the reproduction operation by the viewer By this processing, the reproduction authentication point can be detected from the information of the audiovisual program. Further, by the process of outputting the time when the reproduction authentication point is detected, the information of the time when the reproduction authentication point is detected can be output and used. In addition, in order to transmit to the audiovisual authentication entity that authenticates that the viewer is normally viewing the audiovisual program, the detected reproduction authentication point and the time when the reproduction authentication point is detected are By the process of transmitting to the audiovisual authentication system possessed by the audiovisual authentication entity, the detected reproduction authentication point and the time when the reproduction authentication point is detected can be transmitted to the audiovisual authentication system possessed by the audiovisual authentication entity. Therefore, based on the information on the playback authentication point and the information on the time when the playback authentication point is detected, authentication that the viewer has viewed the audiovisual program by the audiovisual authentication subject can be obtained. .

  The program for controlling the audiovisual terminal of the twenty-first aspect is a program for controlling the audiovisual terminal of the twentieth aspect. For example, the audiovisual terminal 60 (see FIG. 11) is connected to the audiovisual terminal 20 (see FIG. 1). 18 is a control program (not shown) for controlling the audiovisual terminal 60a shown in FIG. 18 operated by the viewer of the audiovisual program incorporating the above function; the program providing entity providing the audiovisual program is specific to the audiovisual program A process for instructing the viewer to perform the operation based on “operation instruction information 101” (see FIG. 3) unique to the audiovisual program that requests the viewer to perform a predetermined operation; Each time the operation is instructed to transmit to the audio-visual authentication entity that authenticates that the audio-visual program is normally viewed, the viewer's response action is performed by the viewer. 23 (see FIG. 1); processing for converting “information related to the response operation of the viewer” obtained from the detection result detected by the motion sensor 23 into a signal that can be transmitted; and output from the audiovisual terminal 60a In order to obtain the viewing authentication, a process for transmitting the information to the audiovisual authentication system 80a (see FIG. 19) possessed by the audiovisual authentication entity is performed.

  For example, a control program (not shown) in which a control program (see FIG. 7) for controlling the audiovisual terminal 20 (see FIG. 1) is incorporated into the control program shown in FIG. 15 for controlling the audiovisual terminal 60 (see FIG. 11). The audiovisual terminal 60a shown in FIG. 18 in which the function of the audiovisual terminal 20 is incorporated in the audiovisual terminal 60 can be controlled by performing the control using. In this case, the audiovisual authentication entity frequently performs a predetermined operation on the viewer as described above, when the viewer reproduces and views the audiovisual program with the audiovisual terminal 60a controlled by the control program. It is possible to perform strict viewing authentication by an audiovisual authentication entity without requesting it.

  With this configuration, this control program is the program according to the eighteenth aspect for controlling the audiovisual terminal; the program providing entity that provides the audiovisual program has the viewing timing at a timing specific to the audiovisual program. A process for instructing the viewer to perform the operation based on operation instruction information unique to the audiovisual program that requests a predetermined operation from the viewer; and authenticating that the viewer is normally viewing the audiovisual program. A process of detecting, by a motion sensor, a response action of the viewer that is performed by the viewer each time the operation is instructed to be transmitted to an audiovisual authentication entity; the viewing obtained from a detection result detected by the motion sensor A process of converting information related to a person's response operation into a signal that can be transmitted; and the audiovisual authentication entity has the information output from the audiovisual terminal to obtain the authentication of the viewing By being configured to perform a process of transmitting the audiovisual authentication system without requiring frequent a predetermined operation to the viewer, it is possible to authenticate the exact viewing by authenticating principal of the visual hearing.

  In addition, the audiovisual authentication system according to the twenty-second aspect is an audiovisual authentication system 80 that authenticates that the viewer of the audiovisual program shown in FIG. 16 is viewing the audiovisual program normally, for example; Reproduction authentication point setting means 81 for providing “reproduction authentication point 110” (see FIG. 12 and FIG. 13), which is a signal for demarcating the program progress time of the audiovisual program at intervals of time; Program transmitting means 82 for transmitting to the audiovisual terminal 60 (see FIG. 11) operated by the viewer in response to the request; the audiovisual detected by the viewer playing the audiovisual program using the audiovisual terminal 60; Receiving means 83 for receiving a “reproduction authentication point 110”, which is a signal provided by the program providing entity providing the program at intervals of a predetermined time in the audiovisual program; A clock 84 for outputting the time 112 when the reproduction authentication point 110 is received (see FIG. 14); and recording the “reproduction authentication point 110” and the “time 112 when the reproduction authentication point 110 is received” in order to authenticate the viewing. And an authentication recording unit 92.

  For example, the audiovisual authentication system 80 shown in FIG. 16 is a dedicated server connected to the WAN of the audiovisual authentication main body, like the audiovisual authentication system 40 (see FIG. 8) described above. Similarly to the audiovisual authentication system 40 described above, a dedicated “information provision homepage” (not shown) that can transmit the outline of the audiovisual program to the viewer of the audiovisual program is presented and transmitted by the viewer. In response to the “program transmission request 100” (see FIG. 17), the viewer is assigned a “viewer ID” (see FIG. 12) and a “password” (viewer simple authentication information) unique to the “viewer ID” (not shown). ) Confirm using both information.

  For example, the reproduction authentication point setting means 81 shown in FIG. 16 defines a “reproduction authentication point 110” (FIG. 16) for demarcating the program progress time of the audiovisual program in the audiovisual program recorded in the program database 91 provided by the program providing entity of the audiovisual program. 12) is installed at predetermined intervals (see FIG. 13). The reproduction authentication point setting means 81 inserts the information of “reproduction authentication point 110” into the information constituting the audiovisual program at the predetermined program progress time of the audiovisual program, and “cycle authentication point 110” constituting the “cycle authentication point 110” The program progress time information defined by the “reproduction authentication point 110” set in the “information” information is encrypted and recorded. The audiovisual program in which the “reproduction authentication point 110” is installed by the reproduction authentication point setting unit 81 is recorded in the program database 91 again.

  For example, the program transmission means 82 shown in FIG. 16 is similar to the program transmission means 41 (see FIG. 8) of the audiovisual authentication system 40 (see FIG. 8) described above, and “viewer ID” (see FIG. 12) and “viewing”. In response to the “program transmission request 100” (see FIG. 17) transmitted from the viewer himself / herself confirmed by the “password” (simple viewer authentication information) (not shown) unique to the “person ID”, This is a streaming server connected to the WAN that transmits the audiovisual program provided by the program providing entity to be recorded to the audiovisual terminal 60 (see FIG. 11) operated by the viewer.

  For example, the receiving means 83 shown in FIG. 16 is detected by the reproduction detecting means 62 included in the audiovisual terminal 60 when the viewer reproduces the audiovisual program using the audiovisual terminal 60 (see FIG. 11). Information of “reproduction authentication point 110” (see FIGS. 12 and 13) returned to the audiovisual authentication system 80 is received by the transmission means 65 (see FIG. 11) provided. The receiving means 83 is an information communication device (high-speed wired information communication device (router)) connected to the WAN.

  For example, the clock 84 shown in FIG. 16 outputs “the time 112 when the reproduction authentication point 110 (see FIGS. 12 and 13) is received” (see FIG. 14) by the receiving unit 83. Since “the time 112 when the reproduction authentication point 110 is received” can be said to be the time when the audiovisual program 60 is reproduced by the audiovisual terminal 60 (see FIG. 11) operated by the viewer, The playback time of the audiovisual program based on the playback time of the audiovisual program and the playback time of the audiovisual program are ascertained from the “time 112 when the playback authentication point 110 is received” output by the clock 84. be able to.

  For example, the authentication recording means 92 shown in FIG. 16 has the information “reproduction authentication point 110” (see FIGS. 12 and 13) and the reception means 83 output by the clock 84 “the time 112 when the reproduction authentication point 110 was received” (FIG. 14) is recorded as information constituting “authentication record 115” (see FIG. 14).

  With this configuration, the audiovisual authentication entity is an audiovisual authentication system for authenticating that a viewer of the audiovisual program held by the audiovisual authentication entity is normally viewing the audiovisual program, The program progress time of the audiovisual program is demarcated by a reproduction authentication point setting means for providing a reproduction authentication point, which is a signal demarcating the program progress time of the audiovisual program, at a predetermined time interval. The reproduction authentication point can be set in the audiovisual program at predetermined time intervals. Further, the audiovisual program is transmitted to the audiovisual terminal operated by the viewer by the program transmitting means for transmitting the audiovisual program to the audiovisual terminal operated by the viewer in response to a request of the viewer, and the viewer The audiovisual program can be presented on the screen. In addition, a reproduction that is a signal provided by the program providing entity that provides the audiovisual program detected by the viewer using the audiovisual terminal to reproduce the audiovisual program is provided in the audiovisual program at predetermined time intervals. The reproduction authentication point returned by the audiovisual terminal operated by the viewer can be received by the receiving means for receiving the authentication point. Further, it is possible to perform authentication by outputting the information of the time when the reproduction authentication point is received by the clock that outputs the time when the reproduction authentication point is received by the receiving means. Further, in order to authenticate the viewing, an authentication recording means for recording the playback authentication point and the time when the playback authentication point is received constitutes an authentication record of the playback authentication point and the time when the playback authentication point is received. It can be recorded as information. Therefore, the viewing of the audiovisual program by the viewer can be authenticated based on the authentication record.

  Further, the audiovisual authentication system according to the twenty-third aspect is the audiovisual authentication system according to the twentieth aspect, for example, the receiving means 83 provided in the audiovisual authentication system 80 shown in FIG. 11), the “reproduction authentication point 110” (see FIGS. 12 and 13) and “the time when the reproduction authentication point 110 is detected” (“detection time”) (see FIG. 12) are received. The authentication recording means 92 is further configured to record “reproduction authentication point 110” recorded by the audiovisual terminal 60 and “time when the reproduction authentication point 110 is detected” (“detection time”).

  For example, the receiving means 83 shown in FIG. 16 further includes a “reproduction authentication point 110” (see FIGS. 12 and 13) recorded by the audiovisual terminal 60 (see FIG. 11) operated by the viewer and a clock 63 (see FIG. 12). The “time when the playback authentication point 110 is detected” (“detection time”) (see FIG. 12) is received. Further, the authentication recording unit 92 further includes “reproduction authentication point 110” and “time when the reproduction authentication point 110 is detected” (“detection time”) recorded by the recording unit 64 (see FIG. 11) included in the audiovisual terminal 60. Recorded as information constituting “authentication record 115” (see FIG. 14).

  For example, the audiovisual terminal 60 shown in FIG. 11 is also used in a communication environment where information communication cannot be performed at high speed. The audiovisual terminal 60 operated by a viewer in a communication environment where information communication cannot be performed at high speed reproduces an audiovisual program via a broadcast or reproducible recording medium. The audiovisual terminal 60 includes the “reproduction authentication point 110” (see FIGS. 12 and 13) and the “time when the reproduction authentication point 110 is detected” (“detection time”) output by the clock 63 included in the audiovisual terminal 60 (see FIG. 12). ) Is recorded in the recording means 64 included in the audiovisual terminal 60. The audiovisual terminal 60 is connected to the high-speed telecommunications network after the reproduction of the audiovisual program is completed. The “reproduction authentication point 110” and the “time when the reproduction authentication point 110 is detected” (“detection time”) recorded in the recording means 64 ) Is transmitted to the audiovisual authentication system 80 (see FIG. 16), and viewing authentication by the audiovisual authentication entity can be obtained.

  With such a configuration, the audiovisual authentication entity is further configured such that the receiving means included in the audiovisual authentication system of the audiovisual authentication entity further includes the reproduction authentication point recorded by the audiovisual terminal operated by the viewer and the audio authentication terminal. Even when the viewer is unable to view the audiovisual program by connecting the audiovisual terminal to the high-speed telecommunications network by being configured to receive the time when the playback authentication point is detected, By receiving the reproduction authentication point recorded in the recording means provided in the terminal and the time when the reproduction authentication point is detected, the time when the viewer reproduces the audiovisual program by the audiovisual terminal and the reproduction time of the audiovisual program are obtained. I can grasp it. Further, the authentication recording means further detects the playback authentication point and the playback authentication point by recording the playback authentication point recorded by the audiovisual terminal and the time when the playback authentication point is detected. The recorded time can be recorded as information constituting the authentication record. Therefore, the viewing of the audiovisual program by the viewer can be authenticated based on the authentication record.

  Further, the audiovisual authentication system according to the twenty-fourth aspect is the same as the audiovisual authentication system according to the twenty-second aspect. For example, the audiovisual authentication system 80 shown in FIG. A viewing analysis unit 85 that analyzes and outputs the history of the playback operation by the viewer from the “received time 112” (see FIG. 14); the authentication recording unit 92 outputs the “reception time 112” output by the viewing analysis unit 85. "Reproduction operation history (audiovisual authentication system) 111b" (see FIG. 14) is further recorded.

  For example, the viewing analysis unit 85 shown in FIG. 16 receives “reception” from the “time 112 when the reception authentication point 110 (see FIGS. 12 and 13) received two or more” (see FIG. 14). “Reproduction operation history (audiovisual authentication system) 111b” (see FIG. 14) based on “time 112” is analyzed and output. Further, the authentication recording means 92 uses the “playback operation history (audiovisual authentication system) 111b” based on the “reception time 112” output by the viewing analysis means 85 as information constituting the “authentication record 115” (see FIG. 14). Record.

  With this configuration, the audio-visual authentication entity analyzes the history of reproduction operations performed by the viewer from the time when two or more reproduction authentication points included in the audio-visual authentication system included in the audio-visual authentication entity are received. A reproduction operation history based on the reception time can be obtained by the viewing analysis means for outputting. Further, the authentication recording means can further record the reproduction operation history based on the reception time output by the viewing analysis means, so that the reproduction operation history based on the reception time can be recorded as information constituting the authentication record. . Therefore, it is possible to authenticate that the viewer has viewed the audiovisual program based on the authentication record.

  In addition, the audiovisual authentication system of the twenty-fifth aspect is the same as the audiovisual authentication system of the twenty-third aspect, for example, an audiovisual terminal 60 provided by the audiovisual authentication system 80 shown in FIG. ) Recorded from the “reproduction authentication point 110” (see FIGS. 12 and 13) and “the time when the audiovisual terminal 60 detected the reproduction authentication point 110” (“recording time 113”) (see FIG. 14). And a viewing analysis unit 85 for analyzing and outputting the history of the reproduction operation by the user; the authentication recording unit 92 includes a “reproduction operation history (audiovisual authentication system) 111c” based on the “recording time 113” output by the viewing analysis unit 85. (See FIG. 14) is further recorded.

  For example, the viewing analysis means 85 shown in FIG. 16 includes “reproduction authentication point 110” (FIG. 12, FIG. 12) output by the clock 63 (see FIG. 11) provided in the audiovisual terminal 60 (see FIG. 11) operated by two or more viewers. 13) and “the time when the audiovisual terminal 60 detects the reproduction authentication point 110” (“recording time 113”) (see FIG. 14), the reproduction operation history by the viewer (“reproduction operation history (audiovisual authentication system) 111c”. (See FIG. 14)) and output. Therefore, as described above, a viewer who has viewed an audiovisual program in a communication environment in which information communication cannot be performed at high speed can be performed by the “reproduction authentication point 110” and “reproduction” recorded in the recording unit 64 included in the audiovisual terminal 60 later. Even when “the time when the authentication point 110 is detected” (“recording time 113”) is transmitted, the “playback operation history (audiovisual authentication system) 111c” can be analyzed and output by the viewing analysis means 85.

  For example, the viewing analysis unit 85 shown in FIG. 16 outputs the time (“recording time 113”) output by the clock 63 (see FIG. 11) recorded in the recording unit 64 (see FIG. 11) included in the audiovisual terminal 60 (see FIG. 11). ) (See FIG. 14), analysis is performed by the viewing analysis means 85, and “reproduction operation history (audiovisual authentication system) 111c” (see FIG. 14) based on “recording time 113” is output. Further, the authentication recording unit 92 records the “playback operation history (audiovisual authentication system) 111c” as information constituting the “authentication record 115” (see FIG. 14).

  With this configuration, the audiovisual authentication entity includes the reproduction authentication point and the reproduction authentication recorded by the audiovisual terminals operated by two or more viewers included in the audiovisual authentication system included in the audiovisual authentication entity. The viewing operation history based on the recording time can be obtained by viewing analysis means for analyzing and outputting the history of the playback operation by the viewer from the time when the point is detected. Further, the authentication recording means can further record the reproduction operation history based on the recording time output by the viewing analysis means, thereby recording the reproduction operation history based on the recording time as information constituting the authentication record. . Therefore, it is possible to authenticate that the viewer has viewed the audiovisual program based on the authentication record.

  In addition, the audiovisual authentication system according to the twenty-sixth aspect is the audiovisual authentication system according to the twenty-fourth or twenty-fifth aspect, for example, based on the “playback operation history 111” (see FIG. 14) shown in FIG. Viewing that outputs “viewing authentication (audiovisual authentication system) 114b” (see FIG. 14) based on “playback operation history 111” for authenticating that the viewing of the audiovisual program has been performed for a predetermined time at a playback speed within the range. The authentication recording means 92 is configured to further record “viewing authentication (audiovisual authentication system) 114b” based on the “playback operation history 111” output by the viewing authentication means 86.

  For example, the viewing authentication means 86 shown in FIG. 16 is based on the “playback operation history 111” (see FIG. 14) output by the viewing analysis means 85, and the playback speed (within a predetermined range determined by the audiovisual authentication subject) For example, it is authenticated that the audio-visual program has been viewed for a predetermined time (for example, “60 minutes or more”) based on “reproduction speed of 2 × speed or less”. Further, the authentication recording unit 92 converts the “viewing authentication (audiovisual authentication system) 114b” (see FIG. 14) based on the “playback operation history 111” output by the viewing authentication unit 86 into “authentication recording 115” (see FIG. 14). ) Is recorded as information constituting.

  By configuring in this way, the audiovisual authentication entity is provided for the audiovisual authentication system possessed by the audiovisual authentication entity, based on the reproduction operation history, and the viewer can only play for a predetermined time at a reproduction speed within a predetermined range. The viewing authentication based on the reproduction operation history can be obtained by the viewing authentication means for outputting the viewing authentication based on the reproduction operation history for authenticating that the audiovisual program has been viewed. In addition, the authentication recording unit is configured to further record the viewing authentication based on the playback operation history output by the viewing authentication unit, thereby configuring the authentication recording of the viewing authentication based on the playback operation history. It can be recorded as information. Therefore, based on the authentication record, the audiovisual authentication entity can authenticate that the viewer has viewed the audiovisual program.

  The audiovisual authentication system according to the twenty-seventh aspect is the audiovisual authentication system according to any one of the twenty-second to twenty-sixth aspects, for example, the audiovisual authentication system 40 (see FIG. 8) in the audiovisual authentication system 80 (see FIG. 16).

  When a tuner (not shown) included in the playback unit 21 receives an audiovisual program broadcast, the tuner included in the playback unit 21 is created by the audiovisual authentication system 40 (see FIG. 8) included in the audiovisual authentication entity. The “operation instruction information 101” (see FIG. 3) broadcast by the broadcasting facility is simultaneously received and the information can be read.

  Also, a multimedia player (not shown) included in the playback means 21 shown in FIG. 1 is provided so that it can read the audiovisual program information recorded on a reproducible recording medium and reproduce the audiovisual program. . For this reason, the reproducing means 21 can reproduce the audiovisual program recorded on the recording medium which can be reproduced electromagnetically or optically.

However, the multimedia player included in the reproducing means 21 can be provided so as to be able to reproduce a reproducible recording medium of any standard.

  In the present embodiment, the reproducible recording medium played back by the multimedia player (not shown) included in the playback means 21 shown in FIG. 1 is provided in advance by the audiovisual authentication entity in addition to the audiovisual program information. Information of the created “operation instruction information 101” (see FIG. 3) is recorded and provided. Therefore, the multimedia player included in the playback means 21 can read and use the information of the “operation instruction information 101” (see FIG. 3) together with the audiovisual program information from the playable recording medium.

  Note that information recorded on a reproducible recording medium played back by a multimedia player (not shown) included in the playback means 21 shown in FIG. 1 is provided so as to be recorded by a digital signal system in this embodiment. However, the information recorded on a reproducible recording medium that is reproduced by a multimedia player (not shown) included in the reproducing means 21 may be recorded by an analog signal system.

  Here, the “operation instruction information 101” will be described with reference to FIG. FIG. 3 is an explanatory diagram illustrating information constituting the “operation instruction information 101” according to the first embodiment of the invention. The “operation instruction information 101” is the audiovisual authentication system 40 (see FIG. 8) and the audiovisual terminal 20 as information that the program providing entity of the audiovisual program requests and instructs a predetermined operation from the viewer at a timing specific to the audiovisual program. (See FIG. 1). The “operation instruction information 101” is configured by combining a plurality of pieces of information constituting the “operation instruction information 101”. However, the “operation instruction information 101” may be provided by a configuration of information other than that shown in FIG.

  The “program ID” constituting the “operation instruction information 101” shown in FIG. 3 will be described. The “program ID” is information uniquely given to the audiovisual program in order to specify the audiovisual program that the viewer views. The “program ID” is information given by the audiovisual authentication entity in order to identify one audiovisual program from the audiovisual programs provided by the audiovisual authentication entity.

  The “instruction ID” constituting the “operation instruction information 101” shown in FIG. 3 is information given by the audiovisual authentication entity to individually identify the “operation instruction information 101” created at a timing specific to the audiovisual program. It is. The “instruction ID” is configured by a total number of “operation instruction information 101” given in one audiovisual program and a continuous ascending number starting from 1 given to “operation instruction information 101” in one audiovisual program. Is provided.

  Specifically, the “instruction ID” constituting the “operation instruction information 101” shown in FIG. 3 is, for example, when the total number of “operation instruction information 101” given in one audiovisual program is 20, The “instruction ID” of the “operation instruction information 101” created first in the program is given as “1/20”. However, as shown in the present embodiment, the “program ID” for identifying the audiovisual program in the information of “instruction ID” is provided without separately providing “program ID” and “instruction ID” as separate information. By adding information corresponding to the information, the information for identifying the audiovisual program and the information for identifying the operation instruction are combined with the information of the “instruction ID” alone, and the audiovisual program and the operation are simultaneously performed. Instructions may be provided so that they can be individually identified.

  As shown in detail later, the “viewer ID” that constitutes the “operation instruction information 101” shown in FIG. 3 is the audiovisual program for the viewer himself / herself who is the target of the audiovisual program. This is information unique to the viewer himself / herself issued by the authentication subject. In the present embodiment, the “viewer ID” is provided so as to be issued by an audiovisual authentication entity together with a “password” (viewer simple authentication information) (not shown) unique to the “viewer ID”. Yes. In this embodiment, “viewer ID” and “password” (viewer simple authentication information) unique to “viewer ID” are both composed of character string information composed of 20 alphanumeric text strings. ing. However, the structure of the “viewer ID” and “password” information is not limited to 20 alphanumeric text strings, and the audiovisual authentication entity can arbitrarily determine the information.

  The “transmission time” constituting the “operation instruction information 101” shown in FIG. 3 is transmitted to the viewer by the audiovisual authentication system 40 (see FIG. 8) possessed by the audiovisual authentication entity, which will be described in detail later. Is the recorded information. As will be described later in detail, the “transmission time” is determined by the operation instruction information transmission means 43 (see FIG. 8) output by the clock 49 (see FIG. 8) that outputs the time at which the audiovisual authentication system 40 performs control processing. This is the time when the time when the instruction information 101 "is transmitted to the audiovisual terminal 20 (see FIG. 1) operated by the viewer is recorded. As described later in detail, the “transmission time” is a time that can be used by the audiovisual authentication system 40 to define “time required for communication with the viewer” (secondary information).

  The “instruction time” constituting the “operation instruction information 101” shown in FIG. 3 is the operation instruction means 22 (FIG. 1) output by the clock 28 (see FIG. 1) provided in the audiovisual terminal 20 (see FIG. 1) described in detail later. (See) is information in which the time when the viewer is instructed to operate is recorded. Therefore, when the operation instruction information transmitting means 43 (see FIG. 8) included in the audiovisual authentication system 40 (see FIG. 8) transmits “operation instruction information 101”, nothing is recorded in the “instruction time” information. The “operation instruction information 101” is transmitted in a state where it is not performed (blank). The “instruction time” is a clock 28 for outputting the time when the audiovisual terminal 20 performs control processing after the audiovisual terminal 20 (see FIG. 1) operated by the viewer receives the “operation instruction information 101” from the audiovisual authentication system 40. The time when the operation instruction means 22 (see FIG. 1) outputted by (see FIG. 1) instructs the viewer to perform the operation is provided as the time to be recorded. The “instruction time” is a time that can be used to demarcate “time required for the viewer to respond” (secondary information), as will be described in detail later.

  The “instruction operation” information included in the “operation instruction information 101” illustrated in FIG. 3 is information indicating a predetermined operation that the audiovisual authentication entity requests the viewer. For example, the “instruction operation” information indicates the information “Please shake” (see FIG. 6) to the viewer and instructs the viewer to operate the audiovisual terminal 20 (FIG. 6) operated by the viewer. 1) can be provided so as to instruct the swinging operation regardless of the details of the swinging (exercising).

  Alternatively, the “instruction operation” information included in the “operation instruction information 101” illustrated in FIG. 3 causes the audiovisual terminal 20 (see FIG. 1) operated by the viewer to move in a three-dimensional space, for example, more quantitatively. When specifying the detailed information of the power motion, the acceleration and angular acceleration in each degree of freedom of the orthogonal coordinate system of 3 axes 6 degrees of freedom shown using the specified coordinate system of 3 axes 6 degrees of freedom An instruction can be given by specifying an operation as value information for each series. Alternatively, in the “instruction operation” information, an operation instruction is given by indicating to the viewer information on an operation previously performed by the viewer recorded by the audiovisual authentication system 40 (see FIG. 8) or the audiovisual terminal 20. It is also possible to instruct the viewer to perform the operation again so as to perform the same operation as the operation previously performed by the viewer.

  In the “authentication criteria” information constituting the “operation instruction information 101” shown in FIG. 3, first, the audiovisual authentication entity determines a response operation performed by the viewer in accordance with the operation instructed by the “instruction operation” information. Based on the information of “authentication standard”, it is determined what kind of information acquisition method and conditions are used for detection as a detection result (primary information). In addition, what information processing is performed on the detected detection result (primary information) to determine the information (secondary information) that is indexed as information on the response operation of the viewer is determined. In addition, information about what judgment criteria are used to authenticate the indexed viewer response action information (secondary information) to obtain an authentication result (tertiary information) is recorded by the audiovisual authentication entity. Has been. The audiovisual terminal 20 (see FIG. 1) and the audiovisual authentication system 40 (see FIG. 8) perform authentication by evaluating the response operation of the viewer based on the information of “authentication criteria” constituting the “operation instruction information 101”. It is provided as follows.

  Here, referring back to FIG. 1, a specific operation instruction method for the viewer using the “operation instruction information 101” (see FIG. 3) will be described. The operation instruction means 22 shown in FIG. 1 is an interface device that instructs a viewer to perform an operation based on “operation instruction information 101” (see FIG. 3).

  The operation instruction means 22 shown in FIG. 1 receives “operation instruction information 101” (see FIG. 3) from the reproduction means 21 having an information communication function. However, the operation instruction means 22 is provided so that the operation instruction means 22 has its own information communication function so that the operation instruction means 22 can directly perform information communication without using the reproduction means 21. The means 22 may be provided so that the “operation instruction information 101” can be obtained directly from the audiovisual authentication system 40 (see FIG. 8) possessed by the audiovisual authentication entity.

  The operation instruction means 22 shown in FIG. 1 is based on “operation instruction information 101” (see FIG. 3), for example, “shake to a part of the liquid crystal display screen (see FIG. 6) of the reproduction means 21” The program providing main body of the audiovisual program "" can display the instruction of the operation that requests the viewer to shake the audiovisual terminal 20 that the viewer holds and operates with one hand, by a character string that is shown briefly. Is provided. However, based on the information of “operation instruction information 101”, a more specific operation may be specified and a character string “Please shake vertically” may be displayed.

  Further, the operation instruction means 22 shown in FIG. 1 gives an animation (not shown) to a partial area of the liquid crystal display screen (see FIG. 6) of the reproduction means 21 when instructing a more complicated operation. A sample of the visual movement used may be provided to the viewer to instruct the movement. An example of an operation using an animation displayed on a partial area of the liquid crystal display screen of the reproduction unit 21 by the operation instruction unit 22 is, for example, a path and a speed at which the audiovisual terminal 20 should be moved in a three-dimensional space. The sample may be displayed by animation. With this configuration, the viewer can intuitively know the complicated response operation to be performed, and it is only necessary to perform the response operation in accordance with the animation, so that it is difficult to prevent viewing of the audiovisual program. Further, when the motion instruction means 22 shows a sample of motion using animation to the viewer, an air conduction speaker (not shown) included in the playback means 21 is used to generate a notification sound for alerting the viewer, for example, 1 It is good also as what provides so that it may output for 2 seconds.

  However, the operation instruction means 22 shown in FIG. 1 only needs to be able to instruct the viewer to perform the operation. For example, in order to transmit a command code instructing the viewer to perform a predetermined operation, the operation instruction means 22 blinks a predetermined number of times. It is also possible to have a visual display device such as a light-emitting / flashing device for instructing the operation. Alternatively, the operation instructing unit 22 may have an auditory display device such as a speaker device that instructs the viewer using words to instruct the operation. Alternatively, the operation instruction means 22 has a tactile display device such as a vibration generator using a vibration motor that vibrates a predetermined number of times in order to transmit a command code instructing a predetermined operation, and instructs the operation. It may be a thing. However, instead of using the operation instruction means 22 to display an operation instruction on the playback means 21, a performer of the audiovisual program interrupts the progress of the audiovisual program for a while in the audiovisual program and calls the viewer for an operation instruction. It may be a thing. With this configuration, the operation instruction can be performed while the progress of the audiovisual program is stopped, so that the operation instruction and the response operation by the viewer can be prevented from being superimposed on the progress of the audiovisual program.

  The motion sensor 23 illustrated in FIG. 1 is a detection device that detects a response operation performed by a viewer. In accordance with an instruction from the operation instruction unit 22, the viewer performs a response operation in order to transmit to the audiovisual authentication entity that authenticates that the viewer is normally viewing the audiovisual program. The motion sensor 23 according to the present embodiment has a triaxial 6-degree-of-freedom acceleration sensor (not shown) fixedly provided inside the audiovisual terminal 20. The three-axis six-degree-of-freedom acceleration sensor is provided so as to be fixed near the position of the center of gravity of the audiovisual terminal 20. The viewer can operate by holding the audiovisual terminal 20 with one hand. Therefore, the three-axis six-degree-of-freedom acceleration sensor can indirectly detect the viewer's response action by detecting the movement of the audiovisual terminal 20 in the three-dimensional space.

  Of course, in another embodiment, a three-axis three-degree-of-freedom acceleration sensor (not shown) included in the motion sensor 23 shown in FIG. 1 may be provided. Here, the three degrees of freedom detected by the acceleration sensor may be provided so as to detect acceleration on the orthogonal coordinate axes in the front-rear, left-right, and vertical directions, or detect angular acceleration in the pitch, roll, and yaw directions. It is good also as what is provided. If the degree of freedom detected by the acceleration sensor is limited to three, the structure of the acceleration sensor can be further simplified.

  In particular, even in the detection of a viewer's response operation by a three-axis six-degree-of-freedom acceleration sensor (not shown) included in the motion sensor 23 shown in FIG. Because there are many instructions for actions such as `` shake to the left and right '', `` shake up and down '' or simply `` shake '', the audiovisual authentication entity is in the `` authentication standard '' defined by the audiovisual authentication entity, Of the degrees of freedom in which the three-axis six-degree-of-freedom acceleration sensor can detect the viewer's response action, the degree of freedom of detection used for judgment of viewing authentication is limited to only two degrees of freedom in the left-right direction and the up-down direction. However, sufficient viewing authentication can be performed. Accordingly, it can be said that the degree of freedom on the three orthogonal coordinate axes including the degree of freedom in the front-rear direction is sufficient for the detection of the response operation of the viewer by the acceleration sensor.

  However, it is possible to detect the viewer's response to a more complicated motion instruction “Please wave in figure 8” by detection using a three-axis three-degree-of-freedom acceleration sensor. The response motion by the viewer is only required to be compared with the motion instructed by the “motion response information 101” (see FIG. 3). Therefore, the three-axis 6-degree-of-freedom acceleration sensor (non-defective sensor) included in the motion sensor 23 shown in FIG. As in the case of the figure), it is not always necessary to capture the viewer's response action with 6 degrees of freedom (6 channels). In an extreme case, even when detection by an acceleration sensor with one degree of freedom (one channel) is used as a detection result (primary information), the response operation of the viewer can be compared with the instructed operation.

  In the present embodiment, the audiovisual authentication subject is the viewer's detected by the 3-axis 6-degree-of-freedom acceleration sensor (not shown) included in the motion sensor 23 shown in FIG. A condition for extracting the detection of the response operation as a detection result (primary information) can be defined. For example, the motion response of the viewer in response to the instructions “shake left and right” and “shake up and down” is usually a rotational motion around the wrist or elbow of the viewer. Of the detection of the viewer's response motion detected by the three-axis six-degree-of-freedom acceleration sensor, four degrees of freedom (four channels) are added by adding the rotation of the yaw method and the rotation of the pitch direction in addition to the horizontal and vertical directions. If detection is adopted as a detection result and information on the remaining two degrees of freedom (two channels) is not adopted as a detection result (primary information) (no signal acquisition), unnecessary signal acquisition and information processing are performed. Thus, appropriate signalization (information processing) can be performed promptly without performing.

  Alternatively, a three-axis six-degree-of-freedom acceleration sensor (not shown) included in the motion sensor 23 shown in FIG. 1 is used for operation of the audiovisual terminal 20 by a viewer provided by being pulled out from the inside of the audio visual terminal 20 by a wired cord. It may be fixed inside the controller. In this way, if a part of the audiovisual terminal is configured as a separate controller drawn out from the main body by a wired cord, even if the main body of the audiovisual terminal 20 is difficult to move freely like a desktop PC, the viewer Is suitably signaled as multi-degree-of-freedom motion information via a 3-axis 6-degree-of-freedom acceleration sensor of a motion sensor 23 fixed to a controller that can be moved freely by being held with one hand. (Information).

  The motion sensor 23 shown in FIG. 1 has a three-axis six-degree-of-freedom acceleration sensor (not shown) that converts acceleration and angular acceleration into six degrees of freedom in a three-dimensional space (front-rear, left-right, vertical acceleration, pitch, roll, yaw). It is provided so that it can be decomposed and detected. The triaxial 6-degree-of-freedom acceleration sensor outputs detection of each degree of freedom as needed. The three-axis six-degree-of-freedom acceleration sensor is provided in a small size using a MEMS (Micro-Electro-Mechanical-Systems) technology. The three-axis six-degree-of-freedom acceleration sensor is preferably an acceleration and angular acceleration sensor obtained as a single semiconductor package by integrally resin-molding a plurality of capacitance type acceleration detection circuits.

  Alternatively, acceleration and angular acceleration may be separately detected by a plurality of separately packaged acceleration sensors, or only one of acceleration or angular acceleration may be detected. Or it is good also as what uses the optical angular accelerometer which measures the optical path difference of the laser beam using the mirror or optical fiber which can detect angular acceleration more precisely. Alternatively, a cheaper mechanical accelerometer may be used without using the MEMS technology.

  The motion sensor 23 shown in FIG. 1 has a camera (not shown) fixed to the audiovisual terminal 20 in addition to a triaxial 6-degree-of-freedom acceleration sensor (not shown). The viewer's response operation can be detected by photographing the viewer's response operation with the camera of the motion sensor 23. In this case, the response operation of the viewer can be detected by analyzing the image of the response operation performed by the viewer taken by the camera. The detection device included in the motion sensor 23 only needs to be able to detect the response operation (motion) of the viewer. For this reason, the detection device of the motion sensor 23 may be a known displacement meter such as an optical displacement meter or an ultrasonic displacement meter in addition to the camera. Further, the motion sensor 23 may be provided so as to detect the viewer's response operation only by the triaxial 6-degree-of-freedom acceleration sensor (not shown) without having a camera (not shown), or the motion sensor. 23 may be provided to have only a camera (not shown).

  When using an acceleration sensor (three axes and six degrees of freedom) as a method for detecting the response action of the viewer, there is an advantage that the audio / visual terminal 20 shown in FIG. . Further, as a method of detecting the response operation of the viewer, when using a camera, the present embodiment is implemented by adding a motion detection software using a photo camera provided in the audiovisual terminal 20. There is an advantage that the audiovisual terminal 20 of the form can be realized.

  1 is provided so as to transmit information output from the audiovisual terminal 20 to the audiovisual authentication system 40 (see FIG. 8) possessed by the audiovisual authentication entity. Specifically, the transmission means 29 is an information communication device (wireless LAN communication device (router)) (not shown) that performs information communication by connecting to a public wireless LAN (not shown).

  However, since the transmission means 29 is only required to be able to perform information communication with the audiovisual authentication system 40 (see FIG. 8) possessed by the audiovisual authentication entity, the transmission means 29 is connected to the LAN connected to the WAN using a wired cable. Thus, information communication with the audiovisual authentication system 40 (see FIG. 8) may be performed. Alternatively, the transmission means 29 may be directly connected to the WAN wirelessly or by wire to perform information communication with the audiovisual authentication system 40 (see FIG. 8). Alternatively, the transmission means 29 may be connected to the same LAN as the audiovisual authentication system 40 (see FIG. 8) wirelessly or by wire to perform information communication with the audiovisual authentication system 40 (see FIG. 8). Alternatively, the transmission means 29 may perform information communication by directly connecting to the auditory authentication system 40 (see FIG. 8) wirelessly or by wire. Alternatively, the transmission means 29 may perform information communication using radio waves for mobile phones.

  The information communication method by the transmission means 29 is provided as HTTP (HyperText-Transfer-Protocol), but may be encrypted by SSL (Secure-Sockets-Layer) (HTTPS). Or it is good also as what communicates using an electronic mail by SMTP (Simple-Mail-Transfer-Protocol). A method of information communication by the transmission means 29 can be provided so as to be performed by a communication method of an arbitrary standard (protocol).

  Further, the signal converting means 24 shown in FIG. 1 obtains “information related to the viewer's response operation” (primary information, secondary information, tertiary information) obtained from the detection result (primary information) detected by the motion sensor 23. Is an information processing apparatus that converts the signal into a signal that can be transmitted by the transmission means 29. The signal converting means 24 detects a detection result (primary information) obtained as a result of extracting a useful signal (information) based on an “authentication standard” determined by the audiovisual authentication subject from detection by the motion sensor 23, and detection Information (primary information, secondary information, tertiary information) relating to the response operation of the viewer obtained from the result (primary information) is created and signaled to a signal that can be transmitted by the transmission means 29 and transmitted to the transmission means 29. Deliver.

  For example, first, the signal generating means 24 shown in FIG. 1 detects a viewer's response action by the motion sensor 23 based on an “authentication standard” defined by the audiovisual authentication subject (detection signal (primary) Information). Subsequently, the signal generating means 24 creates secondary information that is an index value by indexing information related to the response operation of the viewer based on the “authentication standard” defined by the audiovisual authentication entity. Further, the signal generating means 24 creates tertiary information as an authentication result by making an authentication judgment on the secondary information as the index value based on the “authentication standard”. Finally, the signal converting means 24 converts all the information (primary information, secondary information, and tertiary information) included in the signal converting means 24 into a signal so that it can be transmitted by the transmitting means 29 and sends it to the transmitting means 29. Deliver.

  Specifically, for example, the signal converting means 24 shown in FIG. 1 detects a viewer's response action by a three-axis six-degree-of-freedom acceleration sensor (not shown) included in the motion sensor 23 based on “authentication criteria” ( By obtaining (selecting) information), it can be converted into a signal and a detection result (primary information) can be created. Signaling means 24 detects analog output voltage signal information from detection by a triaxial 6-degree-of-freedom acceleration sensor (not shown) at an appropriate time (for example, 3 minutes) after motion instruction means 22 instructs the viewer to perform motion. Is obtained (signaled). At this time, since the time for acquiring the analog output voltage signal information is nothing but the time for waiting for the response operation of the viewer, the signal converting means 24 performs the operation instructing the viewer based on the “authentication standard”. Accordingly, it is possible to appropriately signal the response operation of the viewer. The “authentication standard” is transmitted to the audiovisual terminal 20 as “authentication standard” information constituting the “operation instruction information 101” (see FIG. 3).

  Further, the signal generating means 24 shown in FIG. 1 generates a signal when generating an analog output voltage signal from detection of a viewer's response action by a three-axis six-degree-of-freedom acceleration sensor (not shown) provided in the motion sensor 23. Information can be selected by using a band filter (not shown) or by changing a sampling rate for information acquisition. The threshold between the noise included in the detection by a three-axis six-degree-of-freedom acceleration sensor (not shown) and the signal that the audio-visual authentication subject recognizes as an effective response operation by the viewer is determined by the signalizing means 24 using audio-visual authentication. Based on the “authentication standard” set by the subject, it can be set appropriately according to the operation instructed to the viewer. At this time, the noise signal is excluded from the response operation of the viewer based on the threshold value of the signal filter.

  Subsequently, an analog signal is converted into a digital signal at an appropriate sampling rate using an analog / digital conversion circuit (not shown) included in the signal converting means 24. The sampling rate at this time should be appropriately determined according to the operation instructed by the viewer based on the “authentication criteria” so that the response operation performed by the viewer can be sufficiently captured. Is provided.

  The detection result (primary information) obtained in this way is based on an “authentication standard” determined by the audiovisual authentication entity by the signal generating means 24 and is signaled under appropriate conditions according to the operation instructed to the viewer. It becomes. The detection result (primary information) signalized by the signal converting means 24 is transmitted by the transmitting means 29 to the audiovisual authentication system 40 (see FIG. 8) possessed by the audiovisual authentication entity.

  It should be noted that the signaling performed by the signaling means 24 can be provided so as to include signaling for information communication. By receiving the transmission of the detection result (primary information) performed by the transmission unit 29, the audiovisual authentication main body can grasp the information on the response operation of the viewer. Further, based on the detection result (primary information) signaled by the signal converting means 24, the detection result (primary information) is further sequentially checked against the “authentication standard” using the audiovisual authentication system 40 (see FIG. 8). By processing and authenticating, it is possible to authenticate that the viewer has viewed the audiovisual program.

  Further, the signaling means 24 shown in FIG. 1 processes the detection result (primary information) using, for example, numerical analysis in light of the “authentication standard” determined by the audiovisual authentication entity, thereby responding to the viewer. Can be created as secondary information that is indexed based on “authentication criteria” determined by the audiovisual authentication entity. For example, when the “authentication standard” determined by the audiovisual authentication subject is defined as “the difference in the trajectory between the response operation and the instructed operation being at most 7 mm”, the signal converting means 24 By processing the detection result (primary information) appropriately signalized using numerical analysis as follows, the difference between the trajectory between the response action and the instructed action is derived information of the detection result (primary information). Information (secondary information) can be created.

  Specifically, first, “the motion of the audiovisual terminal 20 acquired in time series” is a detection result detected using a three-axis six-degree-of-freedom acceleration sensor (not shown) included in the signalizer 24 shown in FIG. By performing numerical analysis on “acceleration information (digital signal information)” (primary information), “information on motion trajectory (on the orthogonal coordinate axis) of the audiovisual terminal 20”, which is information related to the response operation of the viewer, is obtained. In this case, the detection result is “acceleration information of motion of the audiovisual terminal 20 acquired in time series in three degrees of freedom on the three axes of the orthogonal coordinate system detected by the three-axis six-degree-of-freedom acceleration sensor (digital signal information). ”(Primary information) is subjected to numerical analysis so as to be first-order integrated with time, thereby obtaining information on the response speed of the viewer (the speed of motion of the audiovisual terminal 20). In addition, by performing numerical analysis so as to perform second-order integration with respect to time, the information “acceleration information of motion of the audiovisual terminal 20 acquired in time series (digital signal information)” (primary information), which is also the detection result, It is possible to obtain information on the response motion of the viewer (on the orthogonal coordinate axis) (information on the motion trajectory or displacement of the audiovisual terminal 20 (on the orthogonal coordinate axis)).

  Similarly, “the angular acceleration of the motion of the audiovisual terminal 20 acquired in time series” is a detection result detected using a three-axis six-degree-of-freedom acceleration sensor (not shown) included in the signalizer 24 shown in FIG. When the information of the viewer's response action (the motion trajectory (around the orthogonal coordinate axis) of the audiovisual terminal 20) is obtained by performing a numerical analysis on “information (digital signal information)” (primary information), the detection result "Angular acceleration information (digital signal information) acquired in time series of motion of the audiovisual terminal 20 in degrees of freedom around three axes of an orthogonal coordinate system detected by a three-axis six-degree-of-freedom acceleration sensor (not shown)" By performing a numerical analysis such that (primary information) is first-order integrated with time, information on the angular velocity of the response operation of the viewer (the motion of the audiovisual terminal 20) can be obtained. In addition, by performing numerical analysis so as to perform second-order integration with respect to time, the information “angular acceleration information (digital signal information) of the motion of the audiovisual terminal 20 acquired in time series” (primary information), which is the detection result, is also obtained. Thus, information on the response response trajectory (around the orthogonal coordinate axis) of the viewer (the motion trajectory or rotation angle of the audiovisual terminal 20 (around the orthogonal coordinate axis)) can be obtained.

  As described above, the signal converting means 24 shown in FIG. 1 has information on acceleration of the viewer's response operation (movement of the audiovisual terminal 20) detected by the triaxial 6-degree-of-freedom acceleration sensor (not shown) included in the motion sensor 23 ( Digital signal information) (primary information) can be processed into motion information of an arbitrary dimension by performing numerical analysis, so that information on the response operation of the viewer (the motion of the audiovisual terminal 20) is the audiovisual authentication entity. Can be signaled as motion information quantitatively indicated by digital signal information in any dimension based on the “authentication standard” defined by

  1 is the maximum value (secondary information) of the difference between the trajectory of the response operation of the viewer (the motion of the audiovisual terminal 20) obtained by the numerical analysis and the trajectory of the instructed operation. ) Can be calculated quantitatively. Providing the viewer's response motion (movement of the audiovisual terminal 20) in the dimension of the motion trajectory (unit: mm) provides an acceleration of the viewer's response motion (motion of the audiovisual terminal 20) (unit: m / S ^ 2), angular acceleration (unit: rad / s ^ 2), velocity (unit: m / s), and angular velocity (unit: rad / s), compared to the case of comparison, the audiovisual authentication subject Can be said to be a comparison method that can intuitively grasp and compare the difference in movement (trajectory difference), so that the response action of the viewer can be suitably indexed and indicated as an index value. It can be said that this is a comparative method.

  Further, the signalizing means 24 shown in FIG. 1 converts the response operation of the viewer (movement of the audiovisual terminal 20) in the dimension of the trajectory by a camera (not shown) included in the motion sensor 23 described in detail later. It can also be said that it is preferable to unify the dimension of information with the information of the response operation of the viewer when detecting the response operation of the viewer (the viewer is provided with a camera (not shown) included in the motion sensor 23). ), The viewer's response motion is first detected in the dimension of the trajectory). For this reason, the dimension of the trajectory (unit: unit) is obtained by using numerical analysis of the acceleration information of the response operation of the viewer (the motion of the audiovisual terminal 20) detected by a three-axis six-degree-of-freedom acceleration sensor (not shown) included in the motion sensor 23. : Mm) can be said to be a very useful method as a method for indexing the response behavior of the viewer. However, without performing such numerical analysis, the response operation of the viewer (the motion of the audiovisual terminal 20) detected by the triaxial 6-degree-of-freedom acceleration sensor (not shown) of the motion sensor 23 can be expressed as acceleration, angular acceleration, It may be provided so as to be directly compared in each dimension of velocity and angular velocity.

  The signal converting means 24 shown in FIG. 1 compares the difference between the analyzed response trajectory of the viewer (the motion of the audiovisual terminal 20) and the motion trajectory instructed by the operation instructing means 22, and as a result, For example, the maximum value of the difference between the trajectory of the response action (the motion of the audiovisual terminal 20) and the trajectory of the action instructed by the action instructing means 22 is “5 mm” and an index value (2 Next information) is calculated. Further, the signal converting means 24 converts the created index value (secondary information) based on the “authentication standard” into a signal that can be transmitted by the transmitting means 29 and passes it to the transmitting means 29. The transmission means 29 transmits an index value (secondary information) based on the “authentication standard” to the audiovisual authentication entity. For this reason, the audio-visual authentication entity can grasp the index value (secondary information) obtained by indexing the response operation information of the viewer based on the “authentication standard”. In addition, the audiovisual authentication entity sets the “response standard” using the audiovisual authentication system 40 (see FIG. 8) based on an index value (secondary information) obtained by indexing the response operation of the viewer based on the “authentication standard”. By performing the authentication judgment based on this, it is possible to authenticate that the viewer has watched the audiovisual program.

  1 is indexed based on “authentication criteria” (for example, “the maximum value of the difference between the viewer's response motion trajectory and the instructed motion trajectory is 5 mm). ”) (Secondary information) is determined in accordance with“ authentication criteria ”determined by the audiovisual authentication entity, so that the authentication judgment can be made independently. The result of authentication judgment (tertiary information) performed by the signaling means 24 is, for example, authentication information (tertiary information) that “the signaling means 24 recognizes that the viewer correctly responded”. The transmission means 29 is provided so that it can be signaled by the signalization means 24 so that it can be transmitted. Note that the tertiary information that is the authentication information output by the audiovisual terminal 20 is also provided so as to be transmitted by the transmission means 29 to the audiovisual authentication system 40 (see FIG. 8) possessed by the audiovisual authentication entity.

  In the signalization by the signalization means 24 shown in FIG. 1 above, for example, first, the signal (information) of the viewer based on the “authentication standard” is determined from the response signal (information) of the viewer detected by the motion sensor 23. By making selections, detection results (primary information) useful for viewing authentication were created and signaled. Subsequently, the signaling unit 24 indexes the viewer's response operation based on the “authentication standard” defined by the audiovisual authentication entity from the information of the detection result (primary information), thereby responding to the viewer. Secondary information, which is an index value obtained by indexing, was created. Further, the signal generating means 24 creates tertiary information as an authentication result by making an authentication determination based on the “authentication standard” from the secondary information that is an index value obtained by indexing the response operation of the viewer. As described above, the signal converting means 24 repeatedly processes information based on the “authentication standard” defined by the audiovisual authentication subject derived from the signal (information) of the viewer's response action detection by the motion sensor 23. Information for authenticating the viewing of the audiovisual program by the viewer can be created and signaled.

  Note that an analog output voltage signal (primary information), which is a detection result obtained from the detection of a three-axis six-degree-of-freedom acceleration sensor (not shown) included in the motion sensor 23 shown in FIG. 1, is an operational amplifier (Operational-Amplifier). By performing a calculus operation using the analog output voltage signal information, the response operation of the viewer (the motion of the audiovisual terminal 20) may be analyzed without changing the analog output voltage signal information. The analog output voltage signal information (secondary information) analyzed by the operational amplifier may be converted into digital output voltage signal information using an analog / digital conversion circuit (not shown).

  The motion sensor 23 shown in FIG. 1 has a camera (not shown) that is fixedly provided to the audiovisual terminal 20 in addition to a triaxial 6-degree-of-freedom acceleration sensor (not shown). . For this reason, the signal converting means 24 detects the response operation of the viewer by the camera included in the motion sensor 23, and analyzes the image captured by the camera included in the motion sensor 23, thereby relating to the response operation of the viewer. It is provided so that information can be obtained.

  Specifically, first, the signal converting means 24 shown in FIG. 1 uses a feature point (for example, the position of the viewer's palm) for detecting the response operation of the viewer as a camera for detecting the response operation of the viewer ( It is provided so as to be defined in an image (detection) taken by (not shown). Subsequently, feature points are continuously extracted from each image constituting a series of images, and information obtained by tracking the extracted feature points in time series is acquired as a detection result (primary information). Is provided. As described above, the signal converting unit 24 uses the video (detection) of the response operation of the viewer, which is captured by the camera included in the motion sensor 23, to detect information on the response operation performed by the viewer (for example, the viewer controls the viewer). The motion of the viewer is relative to the camera (detection result) (primary information) (for example, information on the trajectory of the viewer's palm motion) Yes.

  Alternatively, in another embodiment, the signal converting means 24 shown in FIG. 1 is provided so that the feature points are determined in, for example, a landscape image (detection) other than the viewer photographed by the camera (not shown). You can also. In this case, by tracking the detected feature points in time series, it is possible to acquire information on the trajectory of the camera movement with respect to the three-dimensional space (landscape) as a detection result (primary information). Alternatively, the audio-visual sense in which the camera is fixed can be obtained by performing coordinate transformation on an arbitrary origin without determining the information of the movement of the camera with respect to the three-dimensional space (landscape) as a detection result (primary information). Information of response operation (for example, rotation angle of arm of the viewer (an arm swing angle) around the elbow) performed by a viewer who holds the terminal 20 with one hand and operates the detection result (temporal information) It is good also as what is provided so that it may acquire as.

  In still another embodiment, the signalization means 24 shown in FIG. 1 determines feature points as two landmarks in a landscape image (detection) photographed by a camera (not shown). It is also possible to provide information on the locus of the response action performed by the viewer as more three-dimensional movement information (detection result) (primary information). For example, two feature points perform parallel motion and rotational motion in a video in time series while maintaining a constant distance interval in each image constituting a video (detection) in which a series of landscapes are captured. Take the case where the analysis is done as an example. In this case, in the shooting plane perpendicular to the optical axis direction of the camera, the viewer's arm that holds and operates the audio-visual terminal 20 provided with the camera fixed is photographed in the scene (three-dimensional). Information (detection result) (primary information) of the trajectory of the viewer's response motion can be acquired by assuming that the motion is parallel and rotating with respect to (space).

  Further, for example, a case where the analysis is made that the two feature points are moving toward or away from each other in each image constituting a series of scene images (detection) is taken as an example. In this case, the signal converting means 24 shown in FIG. 1 is for the viewer who holds and operates the audiovisual terminal 20 provided with the camera and the camera fixed relative to the optical axis direction of the camera (not shown). It is possible to acquire information (detection results) (primary information) on the trajectory of the viewer's response motion, assuming that the arm is moving forward or backward.

  However, the signalizer 24 shown in FIG. 1 only needs to be able to acquire a detection result (primary information) as a relative motion with respect to the camera (not shown) for the response action performed by the viewer in the three-dimensional space. Image analysis using a video (detection) of a response action taken by a viewer using a camera (for example, a camera fixed to a desktop computer) fixedly provided on a completely fixed audiovisual terminal 20 It is good also as what detects a viewer's response action by performing. In this case, the fixed camera can be regarded as part of the audiovisual terminal, and the response operation by the viewer is, for example, an operation of shaking the viewer's hand.

  Note that information on the viewer's response operation (movement of the audiovisual terminal 20) is obtained by analyzing an image of a video (detection) taken by a camera (not shown) fixed to the audiovisual terminal 20 shown in FIG. In the same manner as the above-described three-axis six-degree-of-freedom acceleration sensor (not shown), the numerical analysis is used to analyze the frame rate (photographing speed) in the video (detection) photographed by the camera. ) Information (digital signal information) of the displacement (on the orthogonal coordinate axis) or the rotation angle (around the orthogonal coordinate axis) of the feature points between the images continuously captured at a fixed time interval defined by By performing a numerical analysis such that the next information) is first-order differentiated with respect to time, information on the speed or angular velocity of the response operation of the viewer (the motion of the audiovisual terminal 20) is also converted to the displacement ( By performing a numerical analysis so that information (digital signal information) (primary information) of rotation angle (around the orthogonal coordinate axis) or information (primary information) is second-order differentiated by time, the response operation of the viewer (of the audiovisual terminal 20) Motion) acceleration or angular acceleration information can be obtained.

  Next, the “operation response information 102” created by the signalizer 24 (see FIG. 1) will be described with reference to FIG. In the present embodiment, the “information related to the response operation of the viewer” obtained from the detection result detected by the motion sensor 23 (see FIG. 1) by the signal converting unit 24 is created as, for example, “operation response information 102”. It is provided to be. The “operation response information 102” is provided so as to include the information of the above “operation instruction information 101” (see FIG. 3) as configuration information. For this reason, each information of “program ID”, “instruction ID”, “viewer ID”, “transmission time”, “instruction time”, “instruction operation”, and “authentication standard” constituting “operation instruction information 101” Are included as information constituting the “operation response information 102”.

  At the “detection time” constituting the “operation response information 102” shown in FIG. 4, the motion sensor 23 (see FIG. 1) output by the clock 28 (see FIG. 1) provided in the audiovisual terminal 20 (see FIG. 1) is viewed. The time when the person's response operation is detected is recorded. The “detection time” output by the clock 28 that outputs the time at which the audiovisual terminal 20 performs control processing, which will be described in detail later, is the operation that is also output by the clock 28 that constitutes the “operation instruction information 101” (see FIG. 3). The instruction means 22 (see FIG. 1) can be used as the time for defining the “time required for the viewer to respond” (secondary information) together with the “instruction time” at which the viewer has instructed the operation.

  Further, the “response motion” information constituting the “motion response information 102” shown in FIG. 4 is a signal detected by a three-axis six-degree-of-freedom acceleration sensor (not shown) included in the motion sensor 23 (see FIG. 1). The detection result (primary information) signalized by the converting means 24 (see FIG. 1) is recorded as digital signal information. Further, the “response operation” information is further detected by a camera (not shown) that the motion sensor 23 (see FIG. 1) supplementarily extracts and extracted by image processing by the signalization means 24 (see FIG. 1). It is provided so that information (detection result) (primary information) of movement of feature points is recorded. Note that the “instruction time” information included in the “operation response information 102” illustrated in FIG. 4 is information included in the “operation instruction information 101” (see FIG. 3). In order to illustrate the constituent information in an easy-to-understand manner, the information is written from the “operation instruction information 101”. However, the “operation response information 102” may be provided by a configuration of information other than that shown in FIG.

  Now, returning to FIG. 2, the detailed configuration of the signal converting means 24 will be described. The signaling means 24 shown in FIGS. 1 and 2 is provided to include an authentication unit 24a for outputting specific authentication information (tertiary information), a response authentication unit 24b, and a time authentication unit 24c. ing. In the present embodiment, an output of authentication judgment (tertiary information) based on “authentication standard” determined by an individual audiovisual authentication entity is performed by these dedicated authentication units included in the signaling unit 24. It has been. Also, the authentication information (tertiary information) output from these dedicated authentication units is transmitted to the audiovisual authentication system 40 (see FIG. 8) possessed by the audiovisual authentication entity by the transmission means 29 (see FIG. 1). As will be described in detail, the audio recording authentication unit 53 (see FIG. 8) provided in the audiovisual authentication system 40 is provided so as to be recorded by the audiovisual authentication entity as information constituting the “authentication record 107” (see FIG. 5). Yes.

  The signaling means 24 shown in FIG. 2 has an audiovisual authentication entity that is based on the viewer's response action detected by the motion sensor 23 (see FIG. 1) and the action instructed to the viewer by the action instruction means 22 (see FIG. 1). It has an authentication unit 24a that authenticates the matching according to a predetermined standard. In the present embodiment, the operation authentication unit 24a included in the signal converting unit 24 includes the viewer's response operation (primary information) detected by the 3-axis 6-degree-of-freedom acceleration sensor (not shown) included in the motion sensor 23. The action instructed by the action instructing unit 22 to the viewer is determined by a predetermined standard determined by the audiovisual authentication subject (for example, “recognize that the action matches when the difference in acceleration is 1.2 G or less at maximum”). In the case of authenticating a match according to “authentication criteria”), “operation authentication (audiovisual terminal) 103a” (see FIG. 5) (tertiary information) is output.

  2 is provided so as to acquire the response operation of the viewer detected by the motion sensor 23 (see FIG. 1) as a detection result (primary information) according to the “authentication standard”. Yes. In addition, the operation authentication unit 24a included in the signalizer 24 refers to the “authentication standard” defined by the audio-visual authentication entity by referring to the “authentication standard” information constituting the “operation instruction information 101” (see FIG. 3). ”Is provided so as to create secondary information that indexes the information of the response operation of the viewer. Specifically, first, the action authentication unit 24a determines the response action of the viewer (the motion of the audiovisual terminal 20 (see FIG. 1)) based on the detection result (primary information) in the three-dimensional space of the orthogonal coordinate system. This is created as acceleration information acquired in time series. On the other hand, the information on the operation instructed by the operation instructing means 22 (see FIG. 1) is also time-series similarly to the “instruction operation” constituting the “operation instruction information 101” (see FIG. 3) by the audio-visual authentication subject. Is recorded as acceleration information.

  The operation authentication unit 24a illustrated in FIG. 2 includes time-series information indicating acceleration information acquired in response to the viewer's response operation (motion of the audiovisual terminal 20 (see FIG. 1)) and motion of “instruction motion”. The “maximum value of acceleration difference” (secondary information) between the acceleration information shown in FIG. The operation authentication unit 24a can specifically calculate that the acceleration difference compared according to the “authentication standard” has, for example, “difference of 0.6 G at maximum” (secondary information) through time series. . In addition, the motion authentication unit 24a uses the “secondary information indexed by the viewer's response motion as“ authentication standard ”(for example,“ the difference in acceleration compared to each other through time series is 1.2 G or less at maximum. It is possible to perform authentication by making an authentication determination based on “authentication standard”). The content of the authentication result (tertiary information) information output by the action authentication unit 24a is, for example, “the action authentication unit 24a recognizes that the response action of the viewer matches the instructed action”. To do.

  If the operation authentication unit 24a shown in FIG. 2 recognizes that the response operation performed by the viewer and the operation instructed to the viewer by the operation instruction means 22 (see FIG. 1) match, the operation authentication is performed. The unit 24a is provided to output “operation authentication (audiovisual terminal) 103a” (see FIG. 5) (tertiary information). When the operation authentication unit 24a outputs “operation authentication (audiovisual terminal) 103a” (tertiary information), in order to notify the viewer that the operation is authenticated by the operation authentication unit 24a. Then, the operation authentication unit 24a uses the playback means 21 (see FIG. 1) to perform notification by video and audio (for example, to present the viewer with the characters and notification sound of “authentication OK” (see FIG. 6)). It is provided as follows. Therefore, the viewer recognizes the operation authentication by the operation authentication unit 24a, ends the response operation, and can concentrate on viewing the audiovisual program again.

  2 includes a response authentication unit 24b in addition to the operation authentication unit 24a. The response authentication unit 24b includes the total number of “motion instruction information 101” (see FIG. 3) and the total number of detections of the viewer's response motion detected by the 3-axis 6-degree-of-freedom acceleration sensor (not shown) included in the motion sensor 23. The “motion response rate” (secondary information) is a predetermined standard determined by the audiovisual authentication subject (for example, “authentication standard” that defines “viewing authentication is performed when the motion response rate is 80% or more”) When the condition is satisfied, “viewing authentication (audiovisual terminal) 105a” (see FIG. 5) (tertiary information) based on the “operation response rate” is output.

  The response authentication unit 24b illustrated in FIG. 2 is based on the “authentication standard” that configures the “operation instruction information 101” (see FIG. 3), similarly to the above-described operation authentication unit 24a. ) Is provided so as to obtain information on the total number (detection results) (primary information) of detection of the viewer's response motion by a three-axis six-degree-of-freedom acceleration sensor (not shown). The response authentication unit 24b is provided so as to refer to the “total number of operation instruction information 101” recorded by the audiovisual authentication subject in the “instruction ID” information constituting the “operation instruction information 101”. . Specifically, the response authentication unit 24b uses “(transmitted“ operation instruction information ”, for example,“ 1/20 ”in the information of“ instruction ID ”which is information constituting the“ operation instruction information 101 ”. The identification number of “101” (continuous ascending order number starting from 1)) / (total number of “operation instruction information 101” to be transmitted (= 20)) ”is given by the audiovisual authentication entity of“ operation instruction information 101 ” It is provided to refer to “total number”. For this reason, the response authentication unit 24b compares an “operation response rate” that compares the total number of detections of the viewer's response operation by the motion sensor 23 with the “total number of operation instruction information 101” based on the “authentication standard”. It can be created as secondary information indexed by the viewer's response behavior.

  For example, in the authentication judgment performed by the response authentication unit 24b shown in FIG. 2, a 3-axis 6-degree-of-freedom acceleration sensor (not shown) included in the motion sensor 23 (see FIG. 1) included in the audiovisual terminal 20 (see FIG. 1) is viewed. Assume that the total number of “motion response information 102” (see FIG. 4) created by detecting the response motion of the person (the number of response motion detections by the motion sensor 23) is 19 throughout one audiovisual program. In this case, the response authentication unit 24b uses 19 (operation response rate) (secondary information) as 19 (number of response operations detected by the motion sensor 23) / 20 (total number of “operation instruction information 101”). , 95%. Further, for example, in the “authentication standard” information constituting the “operation instruction information 101” (see FIG. 3), the “authentication standard” that determines that the viewing authentication is performed when the “operation response rate” is 80% or more. If it is given by the audiovisual authentication entity, the response authentication unit 24b authenticates that the response by the viewer satisfies the viewing authentication condition based on the “operation response rate” (secondary information). Can do.

  When the response authentication unit 24b illustrated in FIG. 2 performs authentication based on the “operation response rate” (secondary information), the response authentication unit 24b performs “viewing authentication (audiovisual terminal) based on the“ operation response rate ”. ) 105a ”(see FIG. 5) (tertiary information). When “viewing authentication (audiovisual terminal) 105a” (tertiary information) based on “operation response rate” is output, in order to notify the viewer that the response authentication unit 24b has authenticated the response. Then, the response authentication unit 24b uses the playback means 21 (see FIG. 1) to make a video and audio notification (for example, to present the viewer with the letters “authentication OK” (see FIG. 6) and a notification sound). It is provided as follows. Therefore, the viewer recognizes the viewing authentication by the response authentication unit 24b, ends the response operation, and can concentrate on viewing the audiovisual program.

  2 includes a time authentication unit 24c in addition to the operation authentication unit 24a and the response authentication unit 24b. Here, the audiovisual terminal 20 (see FIG. 1) is provided with a clock 28 (see FIG. 1) that outputs a time at which the audiovisual terminal 20 performs control processing. The clock 28 is provided so that all the times when the audiovisual terminal 20 performs the control process can be output. The time authentication unit 24c included in the signal converting unit 24 detects the response operation of the viewer by the motion sensor 23 (see FIG. 1) output by the clock 28, and the operation instruction unit 22 (FIG. 1) output by the clock 28. If the time is within a predetermined time range determined by the audiovisual authentication entity from the time when the operation is instructed to the viewer (for example, “within 3 minutes” defined by “authentication criteria”), "Time authentication (audio-visual terminal) 104a" (see FIG. 5) (tertiary information) is output based on "time required by viewer to respond" that is recognized as appropriate. To do.

  In the authentication judgment by the time authentication unit 24c shown in FIG. 2, the time at which the motion sensor 23 (see FIG. 1) output by the clock 28 (see FIG. 1) detects the response action of the viewer is “motion response information 102” ( 4) and recorded as “detection time”. Similarly, the time when the operation instruction means 22 (see FIG. 1) output by the clock 28 instructs the viewer to perform an operation is recorded as “instruction time” constituting the “operation instruction information 101” (see FIG. 3). Yes. Based on the detection of the viewer's response action by the motion sensor 23, the time authentication unit 24c detects the viewer's response action by the motion sensor 23 based on the “authentication criteria” (“motion response information 102”). "Response action" to be configured)) (primary information). Also, “operation response information 102” is created by adding “detection time” information output from the clock 28 as configuration information. In addition, “operation instruction information 101” is recorded in information constituting “operation response information 102”. For this reason, the time authentication unit 24c is based on the “authentication standard” set by the audiovisual authentication entity, and “the time required for the viewer to respond” from “instruction time” to “detection time” (for example, “1 minute Is created as secondary information that is information indexing the response action of the viewer.

  Further, the time authentication unit 24c illustrated in FIG. 2 performs evaluation on the secondary information obtained by indexing the response operation of the viewer in light of the information of “authentication standard”. The information of “authentication standard” is given by the audiovisual authentication entity as the information of “authentication standard” constituting “operation instruction information 101” (see FIG. 3). The time authentication unit 24c determines that the “time required by the viewer for the response” (secondary information) is within a predetermined time range based on the “authentication standard” (for example, the “authentication standard” is “the viewer needs the response.” "Time within 3 minutes" in the case where it is determined that "within 3 minutes" is appropriate), "Time taken by viewer to respond" (secondary information) is appropriate Admit it. Further, when the time authentication unit 24c recognizes that “the time required for the viewer to respond” is appropriate, the “time authentication (audio-visual terminal) 104a” based on the “time required for the viewer to respond” (Refer to FIG. 5) (tertiary information) is output. When the “time authentication (audiovisual terminal) 104a” (tertiary information) based on “the time required for the viewer to respond” is output by the time authentication unit 24c, the time authentication unit 24c performs authentication. In order to notify the viewer of this, the time authentication unit 24c uses the playback means 21 (see FIG. 1) to make a video and audio notification (for example, “authentication OK” (see FIG. 6)) and a notification sound. To the viewer). Therefore, the viewer can recognize the time authentication by the time authentication unit 24c, end the response operation, and concentrate on viewing the audiovisual program.

  Further, the signaling means 24 shown in FIG. 2 further includes “viewer response” based on the authentication result (tertiary information) output by the operation authentication unit 24a, the response authentication unit 24b, and the time authentication unit 24c. It is provided so that "information regarding operation" can be created. For example, the signal converting means 24 can further create authentication information (tertiary information) that “recognizes that all authentication units of operation, response, and time satisfy“ authentication criteria ””. Further, for example, information that “does not satisfy the authentication criteria by the response authentication unit 24b” can be created. Further, for example, statistical authentication (tertiary information) can be performed by further performing statistics based on information of the authentication result (tertiary information). In this way, the signal converting means 24 creates “information relating to the response operation of the viewer” obtained from the detection result detected by the motion sensor 23 (see FIG. 1) based on the “authentication criteria” and the transmission means 29. (See FIG. 1), the signal can be converted into a signal that can be transmitted.

  Also, the information (primary information, secondary information, and tertiary information) signalized by the signaling means 24 shown in FIG. 2 is transmitted to the audiovisual authentication system 40 (see FIG. 1) possessed by the audiovisual authentication entity (see FIG. 1). (See FIG. 8). Therefore, if the audiovisual terminal 20 (see FIG. 1) includes the signalizer 24, the operation authentication unit 24a, the response authentication unit 24b, and the time authentication unit 24c shown in the present embodiment, the audiovisual authentication system 40 However, the information processing apparatus or the authentication apparatus having the same function may not be provided. However, the audiovisual authentication system 40 also includes an information processing device or an authentication device having the same function, and the audiovisual authentication system 40 performs information processing or authentication processing independently, thereby performing information processing or authentication processing by the audiovisual terminal 20. It may be provided to be confirmed. Alternatively, the audiovisual terminal 20 transmits only the detection result (primary information) detected by the motion sensor 23 (see FIG. 1) to the audiovisual authentication system 40 without creating the authentication result (tertiary information), for example. Then, the following information processing (secondary information, creation of tertiary information) may be performed by the audiovisual authentication system 40.

  Returning to FIG. 1, the viewer authentication will be described. The response operation recording means 25 shown in FIG. 1 is a mass storage device (hard disk / memory) in which the “operation response information 102” (see FIG. 4) output from the signal converting means 24 is connected to the response operation recording means 25. It is a database management system that records in a response operation history database (DB) 31. Therefore, the response operation history database 31 is detected by the motion sensor 23 and created as “operation response information 102” by the signalization means 24 (information of “response operation” constituting the “operation response information 102”). ) Can be recorded as a “response operation history”. The “operation response information 102” is information based on the detection result detected by the motion sensor 23. Of course, the response operation recording means 25 only needs to be able to record the detection result (primary information) detected by the motion sensor 23, so that the detection result detected by the motion sensor 23 may be recorded as it is. The response operation recording means 25 and the response operation history database 31 may be provided as an integrated database device.

  The response operation recording means 25 shown in FIG. 1 searches and extracts the information of “response operation history” (“operation response information 102” (see FIG. 4)) recorded in the response operation history database 31 according to an arbitrary search condition. be able to. Specifically, the response action recording unit 25 displays another response result (“response action” constituting the “action response information 102”) based on the instruction of the same action performed by the same viewer as the “response action history”. It is provided so that it can be searched and extracted from.

  The detection result (primary information) detected by the motion sensor 23 shown in FIG. 1 is processed by the signal converting means 24, whereby “response operation” constituting “operation response information 102” (see FIG. 4). Information is recorded in the response operation history database 31. Also, as the information constituting the “operation response information 102”, “operation instruction information 101” (see FIG. 3) corresponding to the “operation response information 102” is recorded. Further, as information constituting the “operation instruction information 101”, information of “viewer ID”, “instruction operation”, and “instruction ID” is provided. For this reason, the response action recording means 25 searches the “response action history” using the search condition that “viewer ID” and “instruction action” are the same and the “instruction ID” is different, thereby making the same It is possible to search and extract other detection results (information of “response operation” constituting “operation response information 102”) (primary information) based on the instruction of the same operation performed by the viewer.

  Further, the response operation comparison unit 26 shown in FIG. 1 includes a detection result (information of “response operation” constituting “operation response information 102” (see FIG. 4)) detected by the motion sensor 23 and response operation recording unit. 25 is provided so that it can be compared with other detection results (information of “response operation” constituting “operation response information 102”) retrieved and extracted by 25. The response operation comparison means 26 quantitatively calculates “difference in detection results” (secondary information) detected by the motion sensor 23 by comparing “response operations” constituting a plurality of “operation response information 102” with each other. I can grasp it.

  The response motion comparison means 26 shown in FIG. 1 is provided so that the “motion response information 102” (see FIG. 4) can be compared with the one-to-one “motion response information 102” information. In addition, the response motion comparison unit 26 is provided so that, for example, an average value or a median value of “response motions” constituting a large number of “motion response information 102” can be calculated by using a statistical method. It has been. Further, the response motion comparison means 26 calculates, for example, an average value of “response motions” constituting a large number of “motion response information 102” calculated by a statistical method, as a “response” It is provided so that it can be compared with “operation”. Alternatively, the response action comparison unit 26 uses other statistical values, for example, the median value of “response actions” constituting a large number of “action response information 102” and “response actions” constituting one “action response information 102”. It can also be provided to compare. In the present embodiment, the response motion comparison unit 26 detects all other detection results (“motion response” based on instructions of the same motion performed by the same viewer, detected and extracted by the response motion recording unit 25. The average value of the “response operation” composing the information 102 ”and the detection result (the“ response operation composing the operation response information 102 ”) detected last by the motion sensor 23 are quantitatively compared with each other. It is provided to output “difference in response operation” (secondary information).

  As described above, all other past detection results except the last detected result are compared with the last detected result (the “response operation” constituting the “operation response information 102” (see FIG. 4)). It is advantageous to use the average value (or statistical value) of the detection results (“response action” constituting “action response information 102”). At this time, even if, for example, a single detection result includes a specific one, the reference comparison target does not change greatly, and stable comparison is possible. Or it is good also as a comparison object on the basis of one typical detection result ("response action which constitutes" action response information 102 ") as a past detection result. For example, the first detection result (“response operation” constituting “operation response information 102”) is set as a comparison target. In this way, it is possible to authenticate whether the viewer at the start of viewing is the same as the current viewer. Furthermore, an average value for several times, for example, 3 to 5 times, from the start of viewing may be taken and used as a comparison target. In this way, even if something unique is included in several actions, by taking an average of several times, the reference comparison target is set to a stable value, and the viewer at the start of viewing It is possible to authenticate whether or not the current viewer is the same.

  Also, the viewer authentication means 27 shown in FIG. 1 has a predetermined standard (“authentication standard”) that determines the “response action difference” (secondary information) quantitatively grasped by the response action comparison means 26 (secondary information). ”(See FIG. 3)). The viewer authentication means 27 includes the detection result lastly detected by the motion sensor 23 (“response action” information constituting the “action response information 102” (see FIG. 4)) (primary information) and the response action recording means 25. The difference (secondary information) from the average value of the other detection results (information of "response action" constituting "action response information 102") (primary information) retrieved and extracted by Within the range of defined standards (for example, when the “authentication standard” is defined as “recognized as the viewer himself / herself when the maximum difference in acceleration is 1.2 G or less”, “the maximum difference in acceleration is 1.2 G or less”) The viewer who has performed the response operation according to the detection result detected by the motion sensor 23 is the viewer himself / herself who provides the audiovisual program. And authenticateThe viewer authentication means 27 performs “viewer authentication (audiovisual terminal) 106a” (see FIG. 5) (tertiary information) when authenticating that the viewer who last responded is the viewer himself / herself. Output. The output “viewer authentication (audiovisual terminal) 106a” (tertiary information) is transmitted by the transmission means 29 to the audiovisual authentication system 40 (see FIG. 8) of the audiovisual authentication entity.

  The “response operation” performed by the viewer used by the viewer authentication means 27 shown in FIG. 1 as a judgment material for authenticating that the viewer is the viewer himself / herself is information on an operation that the viewer himself / herself performs unconsciously. It contains redundant information. Therefore, the “response operation” performed by the viewer himself / herself is a “response operation” that can be reproduced only by the viewer himself / herself, and the “response operation” information is used as authentication key information for identifying the viewer himself / herself. It can be said that this is suitable information. In addition, by using the audiovisual terminal 20 and the audiovisual authentication system 40 (see FIG. 8) according to the present embodiment, the “response operation” performed by the viewer himself / herself without the viewer of the audiovisual program being prevented from viewing the audiovisual program. Can be instantaneously created by the motion sensor 23 and transmitted to the audiovisual authentication system 40 (see FIG. 8) of the audiovisual authentication entity. The audiovisual authentication entity can strictly authenticate the viewer who views the audiovisual program as the viewer himself / herself by using the audiovisual authentication system 40 (see FIG. 8). The viewer authentication by the viewer authentication means 27 may be performed for all the operations requested of the viewer by appropriately determining the operations requested of the viewer. In this case, it is based on the “authentication standard” defined by the audiovisual authentication entity that is determined so as to instruct an appropriate action that can identify the viewer himself / herself, and the authentication result (tertiary information) using the signaling means 24. ) To be authenticated by statistical methods.

  Further, when the audiovisual terminal 20 shown in FIG. 1 includes the response operation recording unit 25, the response operation comparison unit 26, the viewer authentication unit 27, and the response operation history database 31 shown in the present embodiment, the audiovisual authentication system 40 ( In FIG. 8), it is not necessary to provide an information processing device or an authentication device having the same function. However, the audiovisual authentication system 40 (see FIG. 8) also includes an information processing device or authentication device having the same function, and the audiovisual authentication system 40 (see FIG. 8) performs information processing or authentication processing independently. The viewer's authentication by the audiovisual terminal 20 may be confirmed.

  1 is provided so that the communication speed of a public wireless LAN (not shown) to which the audiovisual terminal 20 is connected can be determined by performing trial communication. ing. When the transmission unit 29 determines that the audiovisual terminal 20 is in a communication environment in which information communication can be performed at high speed, the transmission unit 29 communicates between the audiovisual terminal 20 and the audiovisual authentication system 40 (see FIG. 8). There is no need to consider the total amount of information communication between. For this reason, the transmission means 29 performs high-speed and large-capacity bidirectional information communication even when the viewer views the audiovisual program by streaming (stream distribution), thereby allowing the audiovisual authentication system 40 (see FIG. 8) to read “ The operation response information 102 ”(see FIG. 4) is transmitted.

  On the other hand, when the transmission means 29 shown in FIG. 1 determines that there is a communication environment in which high-speed, large-capacity bidirectional information communication cannot be performed in a public wireless LAN (not shown) connected to the audiovisual terminal 20, It is good also as what is provided as the following structures. First, the transmission unit 29 refrains from information communication with the audiovisual authentication system 40 (see FIG. 8) while the audiovisual program is being viewed by a viewer (via a broadcast or playable recording medium). Then, after viewing the audiovisual program by the viewer, the audiovisual terminal 20 operated by the viewer is connected to a communication environment in which information communication can be performed at high speed, and the transmission means 29 determines that the information communication speed is sufficient. In such a state, information such as “operation response information 102” (see FIG. 4) stored in the recording means 32 included in the audiovisual terminal 20 is collectively stored in the audiovisual authentication system 40 (see FIG. 8). Configure to send. By providing in this way, even in a communication environment where high-speed, large-capacity bidirectional information communication cannot be performed in a public wireless LAN (not shown) connected to the audiovisual terminal 20, a viewer by an audiovisual authentication subject Can authenticate that the user has watched the audiovisual program.

  Here, a predetermined operation instructed by the audiovisual authentication entity to the viewer will be described. In order to suitably detect the viewer's response operation using the motion sensor 23 shown in FIG. 1, it is desirable that the predetermined operation requested and instructed by the program provider of the audiovisual program is an appropriate operation. In the present embodiment, the predetermined operation is provided as an operation in which a program providing entity that provides an audiovisual program is independently determined and instructed. However, as long as it is an instruction for an appropriate operation, it may be an operation in which an audiovisual authentication entity that has been approved by the program providing entity is determined and instructed to the viewer. Further, if the predetermined action is appropriately selected, the viewer himself / herself can determine the predetermined action. In this case, first, the viewer of the audiovisual program selects and determines an appropriate operation independently. For example, the viewer himself actually performs the operation, and transmits the operation to the audiovisual authentication system 40 (see FIG. 8) possessed by the audiovisual authentication entity through the audiovisual terminal 20. In addition, when the audiovisual authentication entity recognizes that the operation selected and determined by the viewer is an appropriate operation, the operation selected and determined by the viewer is registered in the audiovisual authentication system 40. What is necessary is just to provide in.

  For example, first, the program providing entity of the audiovisual program (audiovisual authentication entity) instructs the viewer himself / herself to perform the operation while providing the audiovisual program. In this embodiment, a specific operation content such as “shake sideways” is not instructed, but the viewer himself / herself instructs to perform some “operation”. In this case, the “predetermined operation” is an operation that the viewer himself / herself has transmitted to the audiovisual authentication subject in advance. The audio-visual authentication subject performs authentication by comparing the operation performed by the viewer himself / herself with the operation registered in advance in accordance with the operation instruction. With this configuration, since the “predetermined operation” is an operation determined by the viewer himself / herself, the viewer himself / herself can be reliably identified. In addition, since the registered motion includes “habit” of the specific viewer who has determined the motion, the effect of preventing “spoofing” is high. Here, the program providing entity of the audiovisual program that provides the audiovisual program and the audiovisual authentication entity may be the same person.

  In addition, the predetermined operation is not determined in advance, and the audiovisual authentication entity uses a random number table from among a plurality of operation candidates selected in advance by the program providing entity of the audiovisual program. By using it, it is good also as the operation | movement which extracted and determined one operation | movement at random. It can be said that the information regarding the predetermined operation is used as authentication key information necessary for the audio-visual authentication subject to authenticate that the viewer of the audio-visual program has viewed the audio-visual program. It can be as redundant as ever.

  Further, in the viewing authentication performed by the audiovisual authentication entity, the audiovisual authentication entity transmits the “operation response information 102” (see FIG. 4) returned from the viewer of the audiovisual program by the audiovisual authentication system (see FIG. 8). The information of “response operation” received and constituting “operation response information 102” is referred to. When the audiovisual authentication entity refers to the “response operation” information, the predetermined operation clearly distinguishes only the response operation intended by the viewer from the “response operation” information as a noise signal. It is desirable to specify that the operation can be extracted separately. In many cases, noise motion and noise signal superimposition unintended by the viewer will occur in the information of the detection signal for detecting the response operation of the viewer using the motion sensor 23 shown in FIG. For example, there may be a case where a viewer watches an audiovisual program while walking in a shaking train while traveling. For this reason, in order for the audiovisual authentication subject to clearly distinguish the noise motion or noise signal from the response action performed by the viewer, the predetermined motion trajectory, amplitude, acceleration magnitude required for the viewer, It is desirable to determine operational characteristics such as period.

  In order to clearly distinguish the response operation from the noise signal, among the detection of each degree of freedom (channel) detected by the three-axis 6-degree-of-freedom acceleration sensor (not shown) included in the motion sensor 23 shown in FIG. A combination of detection in the left-right direction and yawing direction, or detection in the vertical direction and pitching direction may be used. These correspond to the actions of “shake sideways” and “shake vertically”, respectively, and the response action performed by the viewer translates and rotates the audiovisual terminal 20 held by the viewer with one hand. This is a complex action around the wrist or elbow of the viewer. These operations are easy to distinguish from the movement of a swaying train while driving. In that respect, an exercise for rolling the audiovisual terminal 20 may be requested, but the exercise for rolling the audiovisual terminal 20 is superior to the combination of the former two in that the screen of the audiovisual terminal 20 becomes difficult to see. It can be said that there is something.

  Further, when a response operation performed by the viewer is detected by a camera (not shown) included in the motion sensor 23 (see FIG. 1) to obtain a detection result (primary information), the focal length of the camera (not shown) Taking into consideration the optical conditions of the camera (not shown) such as exposure, depth of field, frame rate, etc. It is desirable to determine the size and speed of the operation instructed to the viewer so that the response operation can be captured as a clear image with a properly exposed image without blurring.

  Here, the information transmitted from the audiovisual terminal 20 (see FIG. 1) to the audiovisual authentication system 40 (see FIG. 8) will be described with reference to FIG. Information transmitted to the audiovisual authentication system 40 by the transmission means 29 (see FIG. 1) provided in the audiovisual terminal 20 is recorded as “authentication record 107” by the authentication recording means 53 (see FIG. 8) provided in the audiovisual authentication system 40. . The “authentication record 107” includes “operation instruction information 101”, “operation response information 102”, “reception time”, “operation authentication 103”, “time authentication 104”, “viewing authentication 105”, “viewer authentication 106”. "Is recorded.

  The “authentication ID” information constituting the “authentication record 107” shown in FIG. 5 is sent for each “operation response information 102” (see FIG. 4) returned from the audiovisual terminal 20 (see FIG. 1) operated by the viewer. An “authentication ID” is assigned and authentication recording is performed. Regarding the “operation response information 102” returned from the viewer, since the audiovisual authentication entity makes an authentication determination step by step, the “authentication ID” is also provided for each authentication determination made by the audiovisual authentication entity. be able to. The audio-visual authentication entity includes an operation instruction (“operation instruction information 101” (see FIG. 3)) and a response operation (“operation response information 102”) performed by the viewer, organized for each “authentication ID”. ), It is possible to authenticate the viewing of the audiovisual program by the viewer.

  The “operation instruction information 101” constituting the “authentication record 107” shown in FIG. 5 includes “operation response information 102” (see FIG. 4) returned from the audiovisual terminal 20 (see FIG. 1) operated by the viewer. "Operation instruction information 101" (see FIG. 3) is recorded. The audiovisual authentication entity is based on the information recorded in the “operation instruction information 101”, for example, the time when the operation instruction means 22 (see FIG. 1) instructs the viewer to operate (“instruction time” (see FIG. 3)). Can be grasped.

  In addition, the “motion response information 102” (see FIG. 1) returned from the audiovisual terminal 20 (see FIG. 1) operated by the viewer is included in the “motion response information 102” information constituting the “authentication record 107” shown in FIG. 4) is recorded. The audiovisual authentication subject is based on the information recorded in the “motion response information 102”, for example, the time when the motion sensor 23 (see FIG. 1) detects the viewer's response motion (the “motion response information 102” The “detection time” (see FIG. 4)) can be grasped. For this reason, the audiovisual authentication system 40 (see FIG. 8) has “instruction time” (see FIG. 3) constituting “operation instruction information 101” (see FIG. 3) and “detection time” constituting “operation response information 102”. ”Can be used to grasp“ the time required for the viewer to respond ”, which is information (secondary information) that is a useful index value for the audio-visual authentication subject to make an authentication decision.

  In addition, in the information of “reception time” constituting the “authentication record 107” shown in FIG. The time when “operation response information 102” (see FIG. 4) received from the terminal 20 (see FIG. 1) is received is recorded. Also, the clock 49 included in the audiovisual authentication system 40 is output as information on “transmission time” (see FIG. 3) constituting “operation instruction information 101” (see FIG. 4) constituting “operation response information 102”. The time when the operation instruction information transmitting means 43 (see FIG. 8) transmits the “operation instruction information 101” to the viewer is recorded. Therefore, the audiovisual authentication system 40 is useful for the audiovisual authentication entity to make an authentication judgment based on the “transmission time” constituting the “operation instruction information 101” and the “reception time” constituting the “authentication record 107”. It is possible to grasp “time required for communication with the viewer”, which is information (secondary information) serving as an index.

  Further, in the information of “operation authentication 103” constituting the “authentication record 107” shown in FIG. 5, the signaling means 24 provided in the audiovisual terminal 20 returned from the audiovisual terminal 20 (see FIG. 1) operated by the viewer. “Operation authentication (audiovisual terminal) 103a” (tertiary information) output by the operation authentication unit 24a (see FIG. 2) included in (see FIG. 1) is recorded. For this reason, the audiovisual authentication system 40 (see FIG. 8) can grasp that the operation authentication unit 24a of the signaling means 24 included in the audiovisual terminal 20 has authenticated the response operation of the viewer.

  Further, the information of “time authentication 104” constituting the “authentication record 107” shown in FIG. 5 includes the signaling means 24 provided in the audiovisual terminal 20 that is returned from the audiovisual terminal 20 (see FIG. 1) operated by the viewer. The “time authentication (audiovisual terminal) 104a” (tertiary information) based on “the time required for the viewer to respond” output by the time authentication unit 24c (see FIG. 2) included in (see FIG. 1) is recorded. It is provided as follows. Therefore, the audiovisual authentication system 40 (see FIG. 8) can grasp that the time authentication unit 24c included in the signaling unit 24 included in the audiovisual terminal 20 has authenticated “the time required for the viewer to respond”. it can.

  In addition, the information of “viewing authentication 105” constituting the “authentication record 107” shown in FIG. “Viewing authentication (audiovisual terminal) 105a” (tertiary information) based on the “operation response rate” output from the response authentication unit 24b (see FIG. 2) of the response (see FIG. 1) is provided. Yes. For this reason, the audiovisual authentication system 40 (see FIG. 8) can grasp that the response authentication unit 24b included in the signaling unit 24 included in the audiovisual terminal 20 has authenticated the “operation response rate”.

  Further, in the information of “viewer authentication 106” constituting the “authentication record 107” shown in FIG. 5, the viewer authentication provided in the audiovisual terminal 20 returned from the audiovisual terminal 20 (see FIG. 1) operated by the viewer. “Viewer authentication (audiovisual terminal) 106a” (tertiary information) output by means 27 (see FIG. 1) is recorded. Therefore, the audiovisual authentication system 40 (see FIG. 8) can grasp that the viewer authentication means 27 included in the audiovisual terminal 20 has authenticated the viewer himself / herself. However, the “authentication record 107” may be provided by a configuration of information other than that shown in FIG.

  Here, with reference to FIG. 6, an example of a response operation by the viewer who operates the audiovisual terminal according to the first embodiment of the present invention, for example, the mobile phone incorporating each element shown in FIG. FIG. 6A shows an outline of the action of the response operation by the viewer (A0). In FIG. 6A, the operation instruction means 22 provided in the audiovisual terminal 20 is provided in a strip shape at the lower part of the liquid crystal display screen included in the reproduction means 21. The viewer (A0) learns while viewing the screen of the audiovisual terminal 20. When the authentication point in the audiovisual program is reached, the viewer (A0) shakes the audiovisual terminal 20 in accordance with the operation instruction. In this example, an operation instruction “Please shake” is displayed on the operation instruction section 22 provided in a belt shape (A1). When the viewer (A0) swings the audiovisual terminal 20 in accordance with the operation instruction, the response operation of the viewer (A0) is detected by the motion sensor 23 (see FIG. 1) provided in the audiovisual terminal 20. Therefore, the operation authentication unit included in the signalizer 24 (see FIG. 1) authenticates the response operation of the viewer (A0). When the response operation of the viewer (A0) is authenticated by the signal converting means 24, “Authentication OK” is displayed on the liquid crystal display screen of the playback means 21 provided in the audiovisual terminal 20 as shown in FIG. ). If the audiovisual program still has an authentication point, the process returns to the beginning (A3). When the next authentication point is reached, an operation instruction is displayed (A1). When the response authentication unit 24b (see FIG. 2) of the signal converting means 24 performs the viewing authentication based on the “operation response rate”, the viewing / listening of the audiovisual program (distance education program) by the viewer (A0) ( (Attendance) is authenticated, and “Attendance OK” is displayed on the liquid crystal display screen as shown (A4).

  As described above, the predetermined operation needs to be determined so that the audiovisual authentication entity can clearly identify the response operation of the viewer. As long as the operation satisfies this condition, the predetermined operation may be, for example, an operation in which the audiovisual terminal 20 shown in FIG. For example, in the vertical or horizontal direction of the liquid crystal display screen in a plane parallel to the liquid crystal display screen that reproduces and displays the video of the audiovisual program included in the playback means 21 included in the audiovisual terminal 20, for example, “3G (gravity on the earth) It may be an operation of shaking only one reciprocating motion at an acceleration of 3 times the acceleration) or more. Moreover, a series of combined operations in which a plurality of these operations are combined in time series may be used. Alternatively, as shown in FIG. 6 (b), if an instruction to gently swing the audiovisual terminal 20 back and forth in parallel with the viewer's line of sight is given, the viewing of the audiovisual program by the viewer may be greatly hindered. No suitable action can be indicated.

  On the other hand, in the present embodiment, in order to confirm whether or not the viewer of the audiovisual program is the viewer himself / herself, there is a scene where the viewer is requested to perform a complicated operation about three times in the audiovisual program of 90 minutes. Is provided. At this time, the audio-visual authentication entity requests an operation of drawing a predetermined character string in the three-dimensional space using the audio-visual terminal 20 shown in FIG. For example, an operation of drawing the letter “B” is required. Alternatively, an operation of drawing a symbol (for example, the symbol shown in FIG. 6C: Infinity) or a plurality of figures (for example, a circle, a triangle, and a rectangle) may be required. In this case, even if the instruction for the predetermined operation is an instruction for requesting the same operation, the response operation performed by a specific viewer in response to the instruction for the same operation is different for each viewer. . In other words, it is easy for viewers to get addicted and to easily identify viewers. If the response operation is an operation including a characteristic peculiar to each viewer, the audio-visual authentication subject can grasp the characteristic of the operation included in the response operation by the motion sensor 23 (see FIG. 1).

  For this purpose, the viewer authentication means 27 (see FIG. 1) provided in the audiovisual terminal 20 shown in FIG. 6C or the viewer authentication means 47 (see FIG. 8) provided in the audiovisual authentication system 40 (see FIG. 8) described in detail later. The response operation performed by the viewer is detected by the motion sensor 23 (see FIG. 1), and the response operation performed by the viewer is included in the response operation recording means 25 (see FIG. 1) or the audiovisual authentication system 40. By being recorded (registered) in the action recording means 46 (see FIG. 8), the viewer is able to perform authentication for identifying the viewer himself / herself from a response action performed later by the viewer. For this reason, the viewer who has performed the response operation can authenticate that the program providing entity of the audiovisual program is the viewer who is the target of the audiovisual program.

  A control program for controlling the audiovisual terminal 20 (see FIG. 1) will be described with reference to FIG. A microprocessor (MPU) 30 (see FIG. 1) included in the audiovisual terminal 20 follows a control program for controlling the audiovisual terminal 20, and a flowchart shown in FIG. 7 exemplifies the execution procedure of the program for controlling the audiovisual terminal 20. It is provided to perform processing according to the procedure shown in FIG. Note that the reproduction means 21, the operation instruction means 22, the motion sensor 23, the signal generation means 24, the response action recording means 25, the response action comparison means 26, the viewer authentication means 27, the clock 28, the transmission means 29, and the response action history database 31. Since the detailed functions of the recording means 32 (see each FIG. 1) have already been described, redundant description will be omitted.

  The control program shown in FIG. 7 first reproduces an audiovisual program using the reproducing means 21 (see FIG. 1) (step M01). Subsequently, based on the “operation instruction information 101” (see FIG. 3) specific to the audiovisual program in which the program providing entity that provides the audiovisual program requests the viewer to perform a predetermined operation at a timing specific to the audiovisual program. 22 (see FIG. 1) is used to instruct the viewer to operate (step M02). Subsequently, detection of the viewer's response action (change in input voltage value) by the triaxial 6-degree-of-freedom acceleration sensor (not shown) of the motion sensor 23 (see FIG. 1) using the signalization means 24 (see FIG. 1). ) At this time, when the detection (change in input voltage) is confirmed, the three axes of the motion sensor 23 are used according to the information of “authentication standard” constituting the “operation instruction information 101” using the signalizing means 24. An appropriate detection result (primary information) is acquired from detection of the viewer's response action by the six-degree-of-freedom acceleration sensor (step M03). Further, the obtained detection result (primary information) is converted into analog / digital signal conversion or the like (if necessary, based on the information of “authentication standard” constituting the “operation instruction information 101” by using the signalization means 24. “Operation response information 102” (see FIG. 4) is created by performing calculus by numerical analysis (step M04, step M05). Finally, the transmission means 29 (see FIG. 1) is used to transmit the “operation response information 102” to the audiovisual authentication system 40 (see FIG. 8) possessed by the audiovisual authentication entity (step M06).

  The execution control process of the audiovisual terminal 20 (see FIG. 1) shown in FIG. 7 is configured to include an auxiliary control process in addition to the main execution process described above. In this control program, in addition to the signalization (informationization) of the response operation of the viewer using the 3-axis 6-degree-of-freedom acceleration sensor (not shown) included in the motion sensor 23 (see FIG. 1) provided in the audiovisual terminal 20 In addition, a process of converting a viewer's response operation into a signal (informatization) is performed by analyzing an image taken by a camera (not shown) included in the motion sensor 23 included in the audiovisual terminal 20. Is provided. In this case, first, the presence or absence of the detection of the image | video image | photographed with the camera which the motion sensor 23 has is confirmed using the signal conversion means 24 (refer FIG. 1) (step M03). Subsequently, a feature point (in this case, the position of both eyes of the viewer) for detecting the response action of the viewer defined in the video (detection) photographed by the camera using the signal converting means 24. Is a feature point, but if there is a feature point that stands out from the viewpoint of image processing, that point may be extracted as a feature point.) To obtain the detection result (primary information) (step M11).

  Subsequently, based on the detection result (primary information), the information on the displacement of the detected feature point (the position of the viewer's eyes) is second-order differentiated with respect to time using the signalization means 24 (see FIG. 1). By performing the numerical analysis as described above, information (three-dimensional acceleration information) of the response operation of the viewer (movement of the audiovisual terminal 20) acquired in time series is created (step M12). Subsequently, “motion response information 102” (see FIG. 4) is created from the information (three-dimensional acceleration information) of the viewer's response motion (movement of the audiovisual terminal 20) acquired in time series (step M05).

  In the control program shown in FIG. 7, information on the response of the viewer (acceleration information) obtained by a three-axis six-degree-of-freedom acceleration sensor (not shown) included in the motion sensor 23 (see FIG. 1), and auxiliary The response information (acceleration information) of the viewer obtained by the camera (not shown) of the motion sensor 23 (see FIG. 1) constitutes the “response information 102” (see FIG. 4). It can be obtained as “operation” information. Therefore, the motion sensor 23 detects the response motion of the viewer by comparing the response motion information (acceleration information) of the two viewers obtained by the 3-axis 6-degree-of-freedom acceleration sensor and the camera. The accuracy can be mutually verified. Alternatively, the average value of the acceleration information based on the detection result (primary information) detected by the triaxial 6-degree-of-freedom acceleration sensor and the acceleration information based on the detection result (primary information) detected by the camera is the response information of the viewer ( It may be determined as acceleration information). Alternatively, either one of the detection results (primary information) (acceleration information) may be corrected by the other detection results (primary information) (acceleration information).

  In the control program shown in FIG. 7, information on the displacement of feature points (detection results) (1) detected by a camera (not shown) included in the motion sensor 23 (see FIG. 1) included in the audiovisual terminal 20 (see FIG. 1). The case where the viewer is configured to obtain information on the response operation of the viewer (three-dimensional acceleration information) by performing a numerical analysis so that the second order) is second-order differentiated with respect to time has been described. While detecting the displacement information (detection result) (primary information) of the feature point detected by using the displacement dimension information without performing numerical analysis, the detection result detected by the triaxial 6-degree-of-freedom acceleration sensor ( (3D acceleration information) (primary information) is subjected to numerical analysis so as to be second-order integrated, and compared with detection results (primary information) detected by the camera as displacement dimension information. Configuration may be.

  Further, in the control program shown in FIG. 7, the audiovisual terminal 20 (see FIG. 1), based on the “operation instruction information 102” (see FIG. 4), the response action recording means 25, the response action comparison means 26, the viewer authentication. Using the means 27 and the response operation history database 31 (see FIG. 1), the viewer is provided to authenticate that the audiovisual program provider is the viewer who is the target of the audiovisual program. (Step M21). When “viewer authentication (audiovisual terminal) 106a” (see FIG. 5) (tertiary information) is output by the viewer authentication means 27, the transmission means 29 (see FIG. 1) outputs “viewer authentication”. (Audio / visual terminal) 106a ”(tertiary information) is transmitted to the audiovisual authentication system 40 (see FIG. 8) of the audiovisual authentication entity (step M22).

  Further, in the control program shown in FIG. 7, the audiovisual terminal 20 (see FIG. 1) uses the authentication unit 24a (see FIG. 2) of the operation of the signaling means 24 (see FIG. 1) to respond to the viewer. It is provided to authenticate that the detection result (primary information) detected by the motion sensor 23 (see FIG. 1) and the operation instructed to the viewer by the operation instruction means 22 (see FIG. 1) match. (Step M31). Further, when “operation authentication (audiovisual terminal) 103a” (see FIG. 5) (tertiary information) is output by the operation authentication unit 24a of the signal converting means 24, the transmission means 29 (see FIG. 1). , “Operation authentication (audiovisual terminal) 103a” (tertiary information) is transmitted to the audiovisual authentication system 40 (see FIG. 8) of the audiovisual authentication entity (step M32). The authentication using the response authentication unit 24b (see FIG. 2) and the time authentication unit 24c (see FIG. 2) of the motion sensor 23 is illustrated because it is the same authentication process as the operation authentication unit 24a. The description is omitted.

  Further, in the control program shown in FIG. 7, the detection result (primary information) is obtained (step M03) using the signal generator 24 (see FIG. 1), and the viewer authentication means 27 (see FIG. 1) is used. When the user authentication (step M21) and the operation authentication (step M31) using the operation authentication unit 24a (see FIG. 2) of the signal generating means 24 (see FIG. 1) have failed, the signal converting means 24 Information indicating that each authentication has failed (tertiary information) is further created and transmitted to the audiovisual authentication system 40 (see FIG. 8) of the audiovisual authentication entity (step M41). However, the program described above may be provided so as to include various auxiliary processes.

The audiovisual authentication system 40 also includes a central processing unit (CPU) 50 that is a control device that controls the audiovisual authentication system 40. Further, each of the operation instruction information transmitting unit 43, the receiving unit 44, the reception information processing unit 45, and the clock 49 is provided with a random access memory (RAM) 54 for supporting each function. Details of the functions of the devices included in the audiovisual authentication system 40 will be sequentially described below.

  The audiovisual authentication system 40 according to the present embodiment shown in FIG. 8 is a dedicated server included in the audiovisual authentication main body connected to the WAN. The program transmission means 41 provided in the audiovisual authentication system 40 is “program transmission request 100” requested by the reproduction means 21 (see FIG. 1) provided in the audiovisual terminal 20 (see FIG. 1) operated by the viewer of the audiovisual program through the WAN. This is a so-called streaming server that transmits the audiovisual program recorded in the program database 51 to the reproduction means 21 provided in the audiovisual terminal 20 based on (see FIG. 10). Note that the description of the communication method between the audiovisual authentication system 40 and the audiovisual terminal 20 is omitted to avoid duplication of description.

  The audiovisual authentication system 40 shown in FIG. 8 also has a function as a homepage server that opens a dedicated “information provision homepage” (not shown) to an unspecified number of viewers through the WAN by the HTTP communication method. (Not shown). The dedicated “information provision homepage” released by the audiovisual authentication system 40 takes the audiovisual program as a distance learning program (viewing) for the viewer (learning) who views (takes the course) the audiovisual program (distance learning program). Useful information (summary of distance education programs and information such as textbooks to be referred to) can be provided. The dedicated “information provision homepage” released by the audiovisual authentication system 40 is created using the HTML language. Therefore, a student (viewer) who takes a distance learning program (audiovisual program) operates a web browser (not shown) of the audiovisual terminal 20 (see FIG. 1) operated by the student (viewer). Thus, by browsing a dedicated “information providing homepage” published by the audiovisual authentication system 40, it is possible to obtain information on a distance education program (audiovisual program) that can be taken (viewed). In addition, a student (viewer) who takes a distance learning program (audiovisual program) selects a distance education program (audiovisual program) to be attended and uses the dedicated “information provision homepage” for the audiovisual authentication system 40. A “program transmission request 100” (see FIG. 10) can be performed. However, the dedicated “information providing homepage” may be created by another markup language such as XML language (Extensible-Markup-Language).

  When the “program transmission request 100” (see FIG. 10) is transmitted by the student (viewer), the audiovisual authentication system 40 shown in FIG. 8 receives the student (viewer) who transmitted the “program transmission request 100”. ) Simply authenticates whether or not the program providing entity that provides the distance learning program (audiovisual program) is the subject of the distance education program (audiovisual program). The audiovisual authentication system 40 transmits a “program transmission request 100” by presenting a dedicated “information provision homepage” (simple viewer authentication page) for simply authenticating the student himself / herself (the viewer himself / herself). In the appropriate input field of the dedicated “information provision homepage” (viewer simple authentication page), the “viewer ID” (see FIG. 3) and the “password” unique to the “viewer ID” are given to the student (viewer). It requests to input both (viewer simple authentication information) (not shown).

  The “viewer ID” (see FIG. 3) and the “password” (viewer simple authentication information) (not shown) unique to the “viewer ID” are preliminarily stored as a distance learning program (audiovisual program) by an audiovisual authentication entity. The program providing entity to be provided is issued to the student himself / herself (the viewer himself / herself) who is the object of the provision of the distance learning program (audiovisual program). The “viewer ID” and “password” (viewer simple authentication information) unique to the “viewer ID” are both character string information composed of 20 alphanumeric text strings. However, the configuration of the “viewer ID” and “password” information is not limited to 20 alphanumeric text strings, and can be determined as appropriate.

  The program transmitting means 41 shown in FIG. 8 is a dedicated “information provision homepage” that is made public by the audiovisual authentication system 40 through the audiovisual terminal 20 (see FIG. 1) operated by the student (viewer). In the appropriate input field for "viewer ID" (see Fig. 3) and "password" (viewer simple authentication information) (not shown) specific to "viewer ID" are correctly entered.

  Further, for example, the operation instruction information creating means 42 shown in FIG. 8 has an “operation specific to an audiovisual program including information that a program providing entity providing the audiovisual program requests a predetermined operation from the viewer at a timing specific to the audiovisual program. Instruction information 101 "(see FIG. 3) is created. The operation instruction information creating unit 42 refers to information indicating timing specific to the audiovisual program determined by the program providing entity of the audiovisual program recorded in the program database 51 connected to the operation instruction information creating unit 42. The “operation instruction information 101” is created at a timing specific to the audiovisual program. Specifically, the creation of the “operation instruction information 101” by the operation instruction information creating means 42 is provided in advance in the information constituting the audiovisual program provided by the program provider recorded in the program database 51 in advance. This is done by providing trigger information for instructing the operation instruction information creating means 42 to create “operation instruction information 101” at the timing (program progress time) determined by the subject. However, the timing of creating the “motion instruction information 101” by the motion instruction information creating means 42 uses a statistical method or a random determination method using random numbers so that the viewer can be alerted to the audiovisual program. It is good also as what decides.

  The operation instruction information creating means 42 shown in FIG. 8 is provided so as to add “program ID” information unique to the audiovisual program to “operation instruction information 101” (see FIG. 3). The operation instruction information creating means 42 is provided so as to give “instruction ID” information unique to “operation instruction information 101”. The “instruction ID” information is an identification number given to the “operation instruction information 101” by a sequential ascending number starting from 1. In addition, information indicating the total number of “operation instruction information 101” provided in one audiovisual program is given to the information of “instruction ID”. The information of “instruction ID” is given as “1/20” as described above, for example. The operation instruction information creating means 42 is provided so as to give “viewer ID” information unique to the viewer himself / herself to “operation instruction information 101”. As described above, the viewer himself / herself who can give the “viewer ID” information is a password by the dedicated “information provision homepage” (viewer simple authentication page) possessed by the audiovisual authentication system 40. (Not shown). As for the “transmission time” information and the “instruction time” information, as described above, the operation instruction information transmission means 43 and the operation instruction means 22 (see FIG. 1) included in the audiovisual terminal 20 (see FIG. 1) later. Since the time at which each process is executed is recorded, the “operation instruction information 101” is created in a blank state.

  Further, the operation instruction information creating means 42 shown in FIG. 8 is a qualitative operation instruction (for example, “viewer operates” for a predetermined operation instruction determined by the program providing entity recorded in the program database 51. “Instructions for shaking the audiovisual terminal 20 only once in a vertical direction with respect to the display screen for displaying the audiovisual program of the audiovisual terminal 20 (see FIG. 1)” are “authentication standards” determined by the audiovisual authentication entity. To provide a quantitative instruction (for example, “an action of swinging the audiovisual terminal 20 in a three-dimensional space of an orthogonal coordinate system in a vertical direction at a speed of 3 G or more”) based on It has been. At this time, the “authentication standard” defined by the audiovisual authentication subject is determined so that the response operation of the viewer can be obtained as the detection result (primary information) without being disturbed by noise motion and noise signal. It is done. Further, the operation instruction information quantitatively generated by the operation instruction information creating unit 42 is converted into “instruction operation” information constituting the “operation instruction information 101” (see FIG. 3) by the operation instruction information creating unit 42.

Alternatively, the operation instruction means 22 (see FIG. 1) provided in the above-described audiovisual terminal 20 (see FIG. 1) performs the quantitative operation instruction and the animation as an example of the operation performed by the operation instruction information creating means 42. It is good. Since these functions may be realized by the cooperation of the audiovisual authentication system 40 and the audiovisual terminal 20, the audiovisual authentication system 40 and the audiovisual terminal 20 may share the functions as appropriate.

  Further, the operation instruction information transmitting unit 43 shown in FIG. 8 transmits “operation instruction information 101” (see FIG. 3) to the audiovisual terminal 20 (see FIG. 1) operated by the viewer at a timing specific to the audiovisual program. An information communication device. Specifically, the operation instruction information transmission unit 43 is a high-speed wired information communication device (router) connected to the WAN. The operation instruction information transmission unit 43 is created by the operation instruction information generation unit 42 at a timing specific to the audiovisual program, and the “operation instruction information 101” passed to the operation instruction information transmission unit 43 is operated by the viewer. 20 to send. At this time, the “operation instruction information 101” is sent to the audiovisual terminal 20 by the operation instruction information transmitting means 43 output by the clock 49 included in the audiovisual authentication system 40 to the “transmission time” information constituting the “operation instruction information 101”. It is provided so that the transmission time is recorded. In this embodiment, the time at which “operation instruction information 101” is transmitted to the audiovisual terminal 20 by the operation instruction information transmission means 43 output from the clock 49 by the clock 49 constitutes “operation instruction information 101”. It is provided to be recorded as information. However, the operation instruction information creating unit 42 that outputs the clock 49 outputs the “operation instruction information 101” to the operation instruction information transmitting unit 43. The operation instruction information creating unit 42 configures the “operation instruction information 101”. It may be provided so as to be recorded in the “time” information.

  Further, the receiving means 44 shown in FIG. 8 receives “information related to the response operation of the viewer” obtained from the detection result detected by the motion sensor 23 (see FIG. 1) output from the audiovisual terminal 20 (see FIG. 1). An information communication device. Here, the “information regarding the response operation of the viewer” obtained from the detection result detected by the motion sensor 23 output by the receiving audiovisual terminal 20 is used to convey that the viewer is viewing the audiovisual program normally.

Specifically, the receiving unit 44 is a high-speed wired information communication device (router) connected to the WAN, like the operation instruction information transmitting unit 43.

  8 receives the detection result (primary) detected by the motion sensor 23 (see FIG. 1) provided in the audiovisual terminal 20 (see FIG. 1) operated by the viewer received by the receiving means 44. It is an information processing apparatus that creates “information related to viewer response behavior” (secondary information, tertiary information) obtained from (information). The reception information processing means 45 creates “information that indexes the viewer's response behavior” (secondary information) based on the “authentication criteria” from the detection result (primary information) received by the reception means 44. Is provided. Also, the received information processing means 45 authenticates the viewing of the audiovisual program by the viewer based on the “authentication standard” from the “information that indexes the response behavior of the viewer” (secondary information) based on the “authentication standard”. "Information to be performed" (tertiary information) is provided.

  Further, the authentication recording means 53 shown in FIG. 8 accumulates and records information as a basis for “authentication record 107” (see FIG. 5), which is the basis for the audiovisual authentication entity to authenticate the viewing of the audiovisual program by the viewer. It is. The authentication recording means 53 outputs “information for authenticating that the viewer has viewed the audiovisual program” output by the audiovisual authentication system 40 and the audiovisual terminal 20 (see FIG. 1) in order to authenticate the viewing of the audiovisual program by the viewer. (Primary information, secondary information, and tertiary information) are provided so as to be collected and recorded as information constituting the “authentication record 107”.

  Here, with reference to FIG. 9, the information processing unit included in the reception information processing unit 45 will be described. The reception information processing unit 45 includes an operation analysis specifying unit 45 a as an information processing unit included in the reception information processing unit 45. The motion analysis specifying unit 45a included in the reception information processing unit 45 is received by the motion sensor 23 (see FIG. 1) output from the audiovisual terminal 20 (see FIG. 1) operated by the viewer received by the receiving unit 44 (see FIG. 8). The detected detection result (primary information) is analyzed, and the viewer's response action (movement of the audiovisual terminal 20 in the three-dimensional space) is specified. The motion analysis specifying unit 45a included in the received information processing unit 45 performs numerical analysis of the viewer's response motion (motion in the three-dimensional space of the audiovisual terminal 20) from the detection result (primary information) to thereby obtain acceleration, angular acceleration, It is provided so that it can be specified in each dimension of velocity, angular velocity, displacement (on three orthogonal coordinates), and displacement (around three orthogonal coordinates). That is, the motion analysis specifying unit 45a included in the received information processing unit 45 responds to the viewer from analog / digital signal conversion to calculus by numerical analysis performed by the signal converting unit 24 (see FIG. 1) included in the audiovisual terminal 20. It is provided to perform information processing similar to information processing for analyzing the motion of the audiovisual terminal 20). However, when information processing is performed by the motion analysis specifying unit 45a included in the reception information processing unit 45, it is not necessary to perform the same information processing by the signalization unit 24 included in the audiovisual terminal 20.

  As described above, the audiovisual authentication system 40 (see FIG. 8) and the audiovisual terminal 20 (see FIG. 1) determine whether the audiovisual authentication entity is based on the detection result (primary information) detected by the motion sensor 23 (see FIG. 1). Based on the “authentication criteria” that we define, we collaborate in information processing to create “information about the viewer's response behavior” (primary information, secondary information, tertiary information) obtained from the detection results (primary information) What is necessary is just to be provided so that a function may be shared and provided so that it can be performed. Therefore, when either one of the audiovisual authentication system 40 and the audiovisual terminal 20 has the necessary information processing function, the other need not have the same information processing function. But it is good also as what verifies information processing mutually as what is provided so that the same information processing may be performed in both the audiovisual authentication system 40 and the audiovisual terminal 20. FIG.

  The reception information processing unit 45 shown in FIG. 9 is provided so as to have an operation authentication unit 45b as an information processing unit included in the reception information processing unit 45. The operation authentication unit 45b included in the received information processing unit 45 includes a viewer response operation and an audiovisual authentication system (from the detection result detected by the motion sensor 23 (see FIG. 1) provided in the audiovisual terminal 20 (see FIG. 1)).

  Further, the reception information processing means 45 shown in FIG. 9 is provided so as to have a first time authentication unit 45c. In addition, the audiovisual authentication system 40 (see FIG. 8) is provided with a clock 49 (see FIG. 8) that outputs a time when the audiovisual authentication system 40 performs control processing. The first time authentication unit 45c included in the reception information processing unit 45 included in the audiovisual authentication system 40 is operated by the operation instruction information transmitting unit 43 (see FIG. 8) output by the clock 49 (see FIG. 3). ), The motion sensor 23 (see FIG. 1) included in the audiovisual terminal 20 transmitted by the audiovisual terminal 20 (see FIG. 1) by the receiving means 44 (see FIG. 8) that also outputs the clock 49. The “time required for communication with the viewer” (secondary information) up to the time (“reception time”) at which the “information regarding the response operation of the viewer” obtained from the detection result detected by the Within a predetermined time range determined by the subject (for example, if the “authentication criteria” stipulates that “no more than 5 minutes” is appropriate for “time required for communication with viewers” It is provided to authenticate that it is the minute within ").

  When the authentication unit 45c of the first time included in the reception information processing unit 45 shown in FIG. 9 performs such authentication, the “time required for communication with the viewer” (secondary information) is appropriate. And “time authentication (audiovisual authentication system) 104b” (see FIG. 5) (tertiary information) based on “time required for communication with the viewer” is output. Also, the authentication recording means 53 (see FIG. 8) provided in the audiovisual authentication system 40 (see FIG. 8) outputs “required for communication with viewer” output from the first time authentication unit 45c of the received information processing means 45. "Time authentication (audiovisual authentication system) 104b" (tertiary information) based on the "performed time" is recorded as information constituting "authentication record 107" (see FIG. 5).

  For this reason, the audiovisual authentication entity uses the first time authentication unit 45c included in the reception information processing unit 45 shown in FIG. 9, and the audiovisual authentication system (see FIG. 8) included in the audiovisual authentication entity includes the clock 49. By keeping the output time (see FIG. 8) at an appropriate time, it is possible to authenticate the viewing of the audiovisual program by the viewer based on the objective time managed by the audiovisual authentication entity. As described above, when the reception information processing unit 45 included in the audiovisual authentication system 40 includes the first time authentication unit 45c, in the audiovisual terminal 20 (see FIG. 1), the signalizing unit 24 included in the audiovisual terminal 20 is provided. It is not necessary for (see FIG. 1) to have the time authentication unit 24c (see FIG. 2). But it is good also as what is provided so that verification of information processing may mutually be performed by providing so that the same information processing may be performed in both the audiovisual authentication system 40 and the audiovisual terminal 20.

  The reception information processing means 45 shown in FIG. 9 has a second time authentication unit 45d. The second time authentication unit 45d is provided to output “time authentication (audiovisual authentication system) 104b” (see FIG. 5) (tertiary information) based on “the time required for the viewer to respond”. ing. “Time authentication (audiovisual authentication system) 104b” (third-order information) is authentication that recognizes that “time required by the viewer for response” (secondary information) is appropriate. Authentication that recognizes that “the time required for the response by the viewer” is appropriate is that the “time required for the response by the viewer” (secondary information) is within a predetermined time range (for example, the “authentication standard” is “The time required for the viewer to respond” is determined to be “within 3 minutes” when it is determined that “within 3 minutes” is appropriate. Here, “the time required for the viewer to respond” is the audiovisual terminal 20 (see FIG. 1) operated by the viewer received by the receiving means 44 (see FIG. 8) included in the audiovisual authentication system 40 (see FIG. 8). The audiovisual terminal operated by the viewer received by the receiving unit 44 from the time when the operation is instructed to the viewer by the operation instructing unit 22 (see FIG. 1) output by the clock 28 (see FIG. 1) This is the time until the time (“detection time”) at which the response operation of the viewer output by the clock 28 included in 20 is detected by the motion sensor 23 (see FIG. 1) included in the audiovisual terminal 20.

  In this case, the second time authentication unit 45d included in the reception information processing unit 45 shown in FIG. 9 is received by the reception unit 44 (see FIG. 8) included in the audiovisual authentication system (see FIG. 8). The time at which the audiovisual terminal 20 performs the control process, which is output by the clock 28 (see FIG. 1) included in the video signal, is received. The time (“instruction time”, “detection time”) is the detection result (primary information) detected by the motion sensor 23 (see FIG. 1) transmitted by the transmission means 29 (see FIG. 1) included in the audiovisual terminal 20. Is received as “information related to the response operation of the viewer”. Further, based on the time output by the clock 28 included in the audiovisual terminal 20 received by the receiving unit 44, “time required for the viewer to respond” (secondary information) is calculated. Further, based on the “authentication criteria”, “time authentication (audiovisual authentication system) 104b” (see FIG. 5) (tertiary information) based on “time required for the viewer to respond” is output.

  In this way, the audiovisual authentication system 40 (see FIG. 8) and the audiovisual terminal 20 (see FIG. 1) perform information processing, whereby the audiovisual authentication entity authenticates the viewing of the audiovisual program by the viewer. Thus, the audiovisual authentication system 40 and the audiovisual terminal 20 can be provided. In this case, the signaling means 24 (see FIG. 1) included in the audiovisual authentication terminal 20 does not have to have the time authentication unit 24c (see FIG. 2).

  Returning to FIG. 8, the viewer authentication performed by the audiovisual authentication system 40 will be described. The response action recording means 46 provided in the audiovisual authentication system 40 is received by the receiving means 44 in the same manner as the response action recording means 25 (see FIG. 1) provided in the audiovisual terminal 20 (see FIG. 1) operated by the viewer. Further, the detection result (primary information) detected last by the motion sensor 23 (see FIG. 1) included in the audiovisual terminal 20 operated by the viewer (output from the reception information processing unit 45) is connected to the response operation recording unit 46. This is a database management system for recording in the response operation history database 52 which is a large-capacity storage device (hard disk). For this reason, the response operation history database 52 detects the detection result (primary information) detected by the motion sensor 23 included in the audiovisual terminal 20 operated by all viewers received by the receiving unit 44 (output by the reception information processing unit 45). ) As a “response operation history”. However, the response action recording means 46 is not only based on the detection result (primary information) detected by the motion sensor 23 included in the audiovisual terminal 20 operated by the viewer received by the receiving means 44, but also from the detection result (primary information). Derived derivative information (for example, derived information obtained by processing the primary information by performing numerical analysis by the reception information processing means 45) may be provided.

  8 is similar to the response action recording means 25 (see FIG. 1) provided in the audiovisual terminal 20 (see FIG. 1) operated by the viewer described above. Information on “response operation history” to be recorded (detection results (primary information or derived information derived from primary information) detected by the motion sensor 23 (see FIG. 1) included in the audiovisual terminal 20 operated by the viewer) It is provided so that it can be searched and extracted according to the search conditions. In this way, other detection results (primary information or derived information derived from the primary information) based on the instruction of the same action performed by the same viewer are searched and extracted from the “response action history”. Can do.

  Here, the detection result (primary information or primary) detected by the motion sensor 23 (see FIG. 1) received by the receiving means 44 shown in FIG. 8 (or further processed by the reception information processing means 45). Derived information derived from the information is provided so as to be recorded in the response operation history database 52 as “response operation” information constituting the “operation response information 102” (see FIG. 4). Further, as the information constituting the “operation response information 102”, “operation instruction information 101” (see FIG. 3) that is information corresponding to the “operation response information 102” is recorded. Furthermore, as information constituting the “operation instruction information 101”, information of “viewer ID”, “instruction operation”, and “instruction ID” is recorded. For this reason, the response operation recording means 46 searches the “response operation history” using the same “viewer ID” and “instruction operation” and different “instruction ID” as a search condition. It is possible to search and extract another detection result (information of “response operation” constituting “operation response information 102”) based on the instruction of the same operation performed by the viewer.

  8 is similar to the response operation comparison unit 26 (see FIG. 1) provided in the audiovisual terminal 20 (see FIG. 1) operated by the viewer, as described above. (Referred to) is the last detected result (information of “response operation” constituting “operation response information 102” (see FIG. 4)) (primary information), and other information retrieved and extracted by the response operation recording means 46 Detection result (information of “response operation” constituting “operation response information 102”) (primary information). The response motion comparison means 47 quantitatively determines the difference between detection results (primary information or derived information derived from the primary information) detected by the motion sensor 23 by comparing a plurality of “motion response information 102” with each other. I can grasp it.

  8 is similar to the viewer authentication means 27 (see FIG. 1) provided in the audiovisual terminal 20 (see FIG. 1) operated by the viewer, by the response operation comparison means 47. The authentication apparatus evaluates “difference in response operation” (secondary information) quantitatively grasped in accordance with a predetermined standard determined by the audiovisual authentication subject. The viewer authentication unit 48 detects the detection result lastly detected by the motion sensor 23 (“response operation” information constituting the “operation response information 102” (see FIG. 4)) (primary information) and the response operation recording unit 46. "Detection of response action" (secondary information) with other detection results (information of "response action" constituting "action response information 102") (primary information) retrieved and extracted by audiovisual authentication If the subject is within the criteria set by the subject (for example, if the “authentication criteria” stipulates that “the viewer is considered to be the same if the difference in acceleration is 1.2 G or less at the maximum”, If the maximum is 1.2G or less "), the viewer who has made the last response is authenticated so that the program providing entity is the viewer who provides the audiovisual program. In addition, the viewer authentication means 48 authenticates that the viewer who last responded is the viewer himself / herself, “viewer authentication (audiovisual authentication system) 106b” (see FIG. 5) (third order Information). The output “viewer authentication (audiovisual authentication system) 106b” (tertiary information) is recorded by the authentication recording means 53 as information constituting the “authentication record 107” (see FIG. 5). Yes.

  If the audiovisual authentication system 40 shown in FIG. 8 includes response operation recording means 46, operation response comparison means 47, viewer authentication means 48, and response operation history database 52, the audiovisual terminal 20 (see FIG. 1) The response operation recording unit 25, the operation response comparison unit 26, the viewer authentication unit 27, and the response operation history database 31 (see FIG. 1) are not required. But it is good also as what verifies information processing mutually by providing so that the audiovisual authentication system 40 and the audiovisual terminal 20 may perform the same information processing.

  Here, a control program for controlling the audiovisual authentication system 40 (see FIG. 8) will be described with reference to FIG. The central processing unit (CPU) 50 (see FIG. 8) provided in the audiovisual authentication system 40 follows the control program for controlling the audiovisual authentication system 40, and illustrates the execution procedure of the program for controlling the audiovisual authentication system 40. It is provided to perform processing according to the procedure shown in the flowchart. The program transmission means 41, the operation instruction information creation means 42, the operation instruction information transmission means 43, the reception means 44, the reception information processing means 45, the response action recording means 46, the response action comparison means 47, the viewer authentication means 48, the clock 49, the detailed functions of the program database 51, the response operation history database 52, and the authentication recording means 53 (see FIG. 8) have already been described, and duplicate descriptions are omitted.

  With reference to the flowchart of FIG. 10, the example of the execution procedure of the program for controlling the audiovisual authentication system 40 (refer FIG. 8) which concerns on 2nd embodiment of this invention is demonstrated. In this program, first, the program providing entity of the audiovisual program is provided based on the “program transmission request 100” by the viewer transmitted from the audiovisual terminal 20 (see FIG. 1) operated by the viewer to the audiovisual authentication system 40. Information on the audiovisual program recorded in the program database 51 (see FIG. 8) is transmitted to the audiovisual terminal 20 operated by the viewer using the program transmission means 41 (see FIG. 8) (step S01). Subsequently, by using the operation instruction information creating means 42 (see FIG. 8), the program providing entity that provides the audiovisual program is unique to the audiovisual program made up of information requesting a predetermined operation from the viewer at a timing specific to the audiovisual program. "Operation instruction information 101" (see FIG. 3) is created (step S02). Subsequently, the “operation instruction information 101” is transmitted to the audiovisual terminal 20 operated by the viewer using the operation instruction information transmitting unit 43 (see FIG. 8) (step S03). Subsequently, “operation response information 102” (see FIG. 4) transmitted by the transmission means 29 (see FIG. 1) included in the audiovisual terminal 20 operated by the viewer is received using the reception means 44 (see FIG. 8). (Step S04). The “motion response information 102” received here is the motion sensor 23 (see FIG. 5) provided with the response motion performed by the viewer in response to the “motion instruction information 101” as described for the audiovisual terminal 20. 1 ”), which is obtained from the detection result (primary information) detected by (1). Subsequently, by using the motion analysis specifying unit 45a (see FIG. 9) of the reception information processing unit 45 (see FIG. 8), numerically analyzing the information of “response motion” constituting the “motion response information 102”. Identify the viewer's response behavior. Further, using the operation authentication unit 45b (see FIG. 9) of the received information processing unit 45, it is authenticated that the response operation performed by the viewer and the operation instructed by the operation instruction information transmitting unit 43 match (3 Next information) (step S10). Subsequently, “operation response information 102” and “operation authentication (audiovisual authentication system) 103b” (see FIG. 5) (third order) returned from the audiovisual terminal 20 operated by the viewer to the authentication recording means 53 (see FIG. 8). Information) is recorded for authenticating the viewing of the audiovisual program by the viewer, and the success of the operation authentication is transmitted to the viewer (step S11). Of course, the execution control processing of the audiovisual authentication system 40 may include auxiliary control or execution processing in addition to the main execution processing described above.

  In this control program shown in FIG. 10, “response information 102” (see FIG. 4) is further recorded in the response action history database 52 (see FIG. 8) using the response action recording means 46 (see FIG. 8). Processing (step S06) is provided. Subsequently, using the response action recording means 46, the “actions” recorded in another “response action history” previously performed by the same viewer in accordance with the instructions of the same “action instruction information 101” (see FIG. 3). The “response operation” information constituting the “response information 102” is searched, and the “response operation” constituting the “operation response information 102” detected last by using the operation response comparison means 47 (see FIG. 8). A process (step S07) is provided for comparing the information with the “response operation” constituting the other “operation response information 102” retrieved by the response operation recording means 46. Subsequently, the viewer who transmitted the “motion response information 102” detected last based on the comparison result by the motion response comparison unit 47 using the viewer authentication unit 48 (see FIG. 8) Processing for authenticating that the program providing entity is the viewer who is the target of providing the audiovisual program and outputting “viewer authentication (audiovisual authentication system) 106b” (see FIG. 5) (tertiary information) (step 3) M08) is provided. Further, the viewer is notified by communication that the viewer authentication by the viewer authentication means 48 has been successful, and “viewer authentication (audiovisual authentication system) 106b” (3) using the authentication recording means 53 (see FIG. 8). A process (step S09) for recording “next information” as information constituting “authentication record 107” (see FIG. 5) is provided.

  On the other hand, in this control program, when the viewer authentication by the viewer authentication means 48 (see FIG. 8) fails, a process for notifying the viewer that the viewer authentication has failed (step S21). When the operation authentication by the operation authentication unit 45b (see FIG. 9) of the received information processing means 45 (see FIG. 8) fails, the process of notifying the viewer of the failure of the operation authentication (step) S22). However, the program described above may be provided so as to include various auxiliary processes.

  Next, FIG. 20 shows a configuration of an audiovisual terminal 20a according to still another embodiment of the present invention. The audiovisual terminal 20a includes a touch screen detection unit 35 in addition to the configuration of the audiovisual terminal 20 (see FIG. 1). The touch screen detecting means 35 is a projected capacitive touch screen (touch panel) device in which a matrix switch provided by transparent electrodes is superimposed on a liquid crystal display screen (not shown) of the reproducing means 21 provided in the audiovisual terminal 20a. It is provided as. For this reason, the touch screen detection means 35 can specify and detect the position where the viewer touches the touch screen detection means 35 with a finger. In addition, since the touch screen detection means 35 shown in this embodiment is provided by the projection-type capacitance method, it is possible to perform multi-touch detection that can simultaneously detect a large number of conduction points. It is provided so that the viewer can simultaneously touch with a plurality of fingers, but the touch screen detection means 35 only needs to be able to detect the touch by the viewer, so the surface The touch screen may be provided as a capacitive touch screen, or may be provided as a resistive touch screen more simply.

  The operation instruction means 22 shown in FIG. 20 is similar to the operation instruction based on the “operation instruction information 101” (see FIG. 3) described above, and the program providing entity that provides the audiovisual program has a timing specific to the audiovisual program. Is provided to instruct the viewer to perform a predetermined touch based on “touch instruction information” (not shown) unique to the audiovisual program.

  Comparing the “motion instruction information 101” (see FIG. 3) with the “touch instruction information” (not shown), the “motion instruction information 101” typically requests the viewer to respond to a three-dimensional motion. In contrast to information, “touch instruction information” is different in that it is information that only requires the viewer to touch (contact) the touch screen detection means 35 provided on the two-dimensional plane. That is, in the touch requested by the “touch instruction information”, only the touch (contact) to the touch screen detection unit 35 is requested, and the viewer's operation until the touch (contact) is not asked at all. It can be said that the response by the response operation requested by the operation instruction information 101 is different from the response by the touch requested by the “touch instruction information”. For this reason, the response by the response action is a response method that can instantly make a response with a larger amount of information compared to the response by touch (contact), and has a higher information creation efficiency. There are differences that can be made.

  In the present embodiment, based on an operation instruction based on “operation instruction information 101” (see FIG. 3) and a touch instruction based on “touch instruction information” (not shown), the viewer can select either an operation or a touch. An instruction by the operation instruction means 22 is provided so that a response can be made by selecting a response by the above method. Specifically, the operation instruction means 22 is instructed to perform the operation “Please shake” (see FIG. 6) based on the “Operation instruction information 101” described above, and “Please touch” based on the “Touch instruction information”. (Please touch) "(see FIG. 21) is transmitted to the display unit (see FIG. 21) of the operation instruction means 22 by the operation instruction means 22. It is provided so as to instruct the operation with reference to FIG.

  In the present embodiment, the instruction “Please shake or touch” is given to the viewer by the operation instruction means 22 as shown in the lower center portion of the screen as shown in FIG. As a message with a transparent illustration and characters, it is provided to be displayed as an instruction to repeat blinking until a response is made by a viewer for a predetermined time (for example, for “2 minutes”). Specifically, for example, a character string “Please touch the blue part or shake until the display disappears” is displayed in the detection area of the touch screen detection means 35 that is filled with translucent blue and displayed. The response should be instructed. In the present embodiment, the display by the operation instruction means 22 is provided to disappear when the viewer responds by performing either a “shake” operation or a “touch” operation. When the display disappears in response, the request to the viewer (operation instruction) by the operation instruction means 22 is satisfied.

  Rather than responding by performing an operation instructed by the viewer in response to the operation instruction by the operation instructing unit 22 shown in FIGS. 20 and 21, viewing in response to a touch instruction performed simultaneously by the operation instructing unit 22. There are cases where it is easier or more appropriate for the viewer to make a response instructed by the touch screen detection means 35 in view of the surrounding situation when the viewer makes a response. For example, when the viewer is temporarily crowded or crowded, or because the viewer is in a library, etc. For example, you may not want to collect the attention of others. When the viewer views using the audiovisual terminal 20a shown in the present embodiment, the viewer detects the touch screen in response to the touch instruction instructed by the operation instruction means 22 provided in the audiovisual terminal 20a. By selecting to touch the means 35, there is an advantage that a response can be made more silently depending on the situation, compared to a case where a response operation is performed and a response is made. That is, the viewer can respond only by making a quiet touch (contact) to the touch screen detection means 35 without depending on the operation depending on the situation.

  Typically, in the state where the viewer holds the audiovisual terminal 20a shown in FIG. 20 with one hand, the response operation is performed by waving one hand holding the audiovisual terminal 20a and responding. This is a response method that is particularly easy for the user and does not hinder viewing of the audiovisual program. On the other hand, the response by the touch performed by touching the audiovisual terminal 20a with one hand opposite to the one holding the audiovisual terminal 20a (that is, using both hands) may be a relatively burdensome for the viewer. It can be said that this is a response method having In addition, according to the method of authenticating response and viewing using more redundant and unique information, which can be created by the viewer performing a response action, typically created by three-dimensional motion, There is an advantage that the viewing authentication can be performed very strictly. However, depending on the surrounding situation where the viewer is placed as described above, a response method in which the viewer touches the audiovisual terminal 20a with one hand opposite to the one holding the audiovisual terminal 20a and makes a response is more appropriate. There are also cases where it is meaningful. For this reason, the audiovisual terminal 20a shown in the present embodiment is further improved by assisting detection of the viewer's touch by the touch screen detection means 35 in addition to detection of the viewer's response operation by the motion sensor 23. It is provided to be able to provide a response method.

  In the present embodiment, in response to a touch instruction given by the operation instruction means 22 shown in FIG. 20, the viewer selects an arbitrary point on the touch screen detection means 35 (including a case where the area occupies a certain area). It is provided so that a response can be made by touching with a finger. A response method performed only by the viewer touching an arbitrary point on the touch screen detection unit 35 with a finger can be performed in response to an instruction for authentication of viewing by the operation instruction unit 22. Among the response methods, it can be said that it is a method that allows a particularly quiet and simple response. The touch screen detection means 35 is provided so as to be able to detect a touch by a finger or a stylus on an arbitrary point or a plurality of points by a viewer as needed. Further, the signal converting means 24 can obtain the detection result (primary information) that the touch screen detection means 35 has detected, and further, based on the detection result (primary information), the above-mentioned “viewer's As in the case of “information related to response operation”, the “information related to viewer touch” (primary information, secondary information, and tertiary information) detected by the touch screen detecting means 35 can be transmitted by the transmitting means 29. It can be obtained as information. It should be noted that the “information regarding the touch of the viewer” signalized by the signal converting means 24 may be a digital signal / information or an analog signal / information. The “information relating to the viewer's touch” signalized by the signaling means 24 is the audiovisual authentication system 40 possessed by the audiovisual authentication entity by the transmission means 29, as in the case of the “information relating to the response operation of the viewer” described above. (See FIG. 8).

  On the other hand, based on the “touch instruction information” by the operation instruction means 22 shown in FIG. It may be instructed to draw. In this case, the detection result (primary information) detected by the touch screen detection means 35 includes the detection result (primary information) of the response action by the viewer detected by the motion sensor 23 and the “viewer response action”. As in the case of “information about”, by using the signalization means 24, for example, “information about the touch of the viewer” including “information about the locus of the touch performed by the viewer” detected by the touch screen detection means 35. (Primary information and secondary information and tertiary information derived from the primary information). For this reason, it can be said that the response and the viewing authentication can be performed based on more information as compared with the case where the viewer is requested to touch only one arbitrary point of the touch screen detection means 35. For example, when an instruction is given to draw a character string or the like including a feature such as an autographer on the touch screen detection means 35, the audiovisual program is viewed and the viewer is authenticated. Can be performed based on more information.

  However, in this case, the amount of information used for the authentication of viewing of the audiovisual program and the authentication of the viewer and the efficiency of information creation are compared with the method of performing the response and viewing authentication by the response operation described above. Disadvantageous. For this reason, a response by a touch that draws a character string including many characters, for example, including a predetermined amount of information required for strict viewing of an audiovisual program and authentication of the viewer himself / herself is returned and burdens the viewer In some cases, there is a possibility that the strictness of authentication may be reduced due to a lack of information amount. In order to avoid such a possibility, as in the configuration of the audiovisual terminal 20a shown in the present embodiment, the response by the touch detection by the touch screen detection unit 35 and the authentication of the viewing of the audiovisual program (or the viewer's own authentication) Authentication) may be provided so as to temporarily assist the response by detecting the response operation by the motion sensor 23 and the authentication of viewing of the audiovisual program (or the authentication of the viewer himself / herself). Note that the details of the detection of the viewer's touch by the touch screen detection unit 35 and the signalization of the “information related to the viewer's touch” by the signal generation unit 24 and the transmission by the transmission unit 29 are as follows. Since this is the same as the case of the detection of the response operation of the viewer and the signalization of the “information related to the response operation of the viewer” by the signaling means 24 and the transmission thereof by the transmission means 29, description thereof will be omitted.

  When the touch screen detection means 35 is provided as an auxiliary detection device as in the configuration of the audiovisual terminal 20a shown in FIG. 20, for example, a relatively large portable terminal such as “iPad” (registered trademark) is used. Even when viewers watch, the amount of information and the creation efficiency of information are higher, so the response of the response action with higher authentication strictness and the response by quieter and simpler touch can be selected by the viewer Thus, it is possible to select according to the situation, and to more preferably authenticate the response and the viewing of the audiovisual program (or the authentication of the viewer).

  The audiovisual terminal 20a shown in FIG. 20 is not only a small and mobile phone type mobile terminal (for example, “iPhone” (registered trademark)), but also a mobile terminal (for example, “iPad” having a larger large display screen). "(Registered trademark))" or the like. In the case of a large and heavy portable terminal, the response method of responding by touching the audiovisual terminal 20a may be easier than the response method of responding by the response operation of shaking the audiovisual terminal 20a. obtain. For this reason, the audiovisual terminal 20a can respond appropriately by the viewer selecting according to the situation in both cases where the audiovisual terminal 20a is a small portable terminal and a large portable terminal. It is provided as follows.

  In this case, in order for the audio-visual authentication subject to perform appropriate viewing authentication having a desired strictness, for example, an appropriate ratio between the number of responses by the response operation and the number of responses by the touch is previously set to “authentication. It may be determined by “standard”. For example, the audio-visual authentication entity defines, as “authentication criteria”, that “a response is recognized as appropriate when the total number of responses by the response action is 1/3 or more of the total number of responses by the touch”. be able to.

  On the other hand, when the audiovisual terminal 20a shown in FIG. 20 and the audiovisual authentication system 40 (see FIG. 8) of the audiovisual authentication entity mutually perform information communication and authentication of viewing, the operation instruction information included in the audiovisual authentication system 40 As in the case of the “operation instruction information 101” (see FIG. 3) described above, the creating means 42 (see FIG. 8) gives the viewer a predetermined provision to the viewer at a timing specific to the audiovisual program. It is provided so as to create “touch instruction information” (not shown) unique to the audiovisual program, which is made up of information requesting touch. The “touch instruction information” is the same information as the “operation instruction information 101” as described above. Further, the operation instruction information transmitting means 43 (see FIG. 8) provided in the audiovisual authentication system 40 sends “touch instruction information” to the audiovisual terminal 20a operated by the viewer, as in the case of the “operation instruction information 101” described above. Provided to transmit. Also, the receiving means 44 (see FIG. 8) included in the audiovisual authentication system 40 transmits that the viewer is normally viewing the audiovisual program, as in the case of the “information regarding the response operation of the viewer” described above. Therefore, it is provided so as to receive “information relating to the viewer's touch” obtained from the detection result detected by the touch screen detection means 35 provided in the audiovisual terminal 20a operated by the viewer. Also, the reception information processing means 45 (see FIG. 8) provided in the audiovisual authentication system 40 converts the received “information related to the viewer's touch” to “viewing” in the same manner as the “information related to the response operation of the viewer” described above. It is provided so as to be processed into “information for authenticating that the person has viewed the audiovisual program”. For this reason, by using the audiovisual terminal 20a and the audiovisual authentication system 40, it is possible to more appropriately authenticate the response and the viewing of the audiovisual program (or authenticate the viewer himself / herself) according to the situation where the viewer is placed. . For details of the functions and information processing of the audiovisual authentication system 40, the “operation instruction information 101” and “information relating to the response operation of the viewer” and “information for authenticating that the viewer has viewed the audiovisual program” are described above.

  The information on the “reply time” constituting the “reproduction authentication point 110” shown in FIG. 12 is transmitted to the audiovisual terminal 60 (see FIG. 11) by the transmission means 65 (see FIG. 11). The time returned to the audiovisual authentication system 80 (see FIG. 16) possessed by the subject is information on the recorded time. The audiovisual authentication system 80 can grasp the reproduction time and reproduction time of the audiovisual program by the viewer based on the information of “reply time”. Also, the “reply time” information can be used to roughly grasp the communication time required between the audiovisual terminal 60 and the audiovisual authentication system 80, similarly to the “transmission time” information.

  The “authentication criteria” information constituting the “reproduction authentication point 110” shown in FIG. 12 is information in which “maximum reproduction speed” and “minimum reproduction time” of the audiovisual program determined by the audiovisual authentication entity are recorded. “Maximum playback speed” defines the playback speed of an appropriate audiovisual program recognized by the audiovisual authentication entity. When a viewer plays back an audiovisual program at a playback speed that prevents the contents of the audiovisual program from being understood, the viewer shall authenticate the viewing of the portion that has been played back fast forward based on the “authentication criteria”. I can't. The “minimum playback time” defines the minimum time of the audiovisual program that the viewer should view based on the program progress time of the audiovisual program. The “minimum playback time” is set so that the program progress time of the part of the audiovisual program played back by the viewer at an appropriate playback speed is integrated and calculated. The audiovisual terminal 60 (see FIG. 11) and the audiovisual authentication system 80 (see FIG. 16) mutually communicate information on the “reproduction authentication point 110” made up of these pieces of information, thereby authenticating the viewing of the audiovisual program by the viewer. It is provided so that it can be performed. However, the “reproduction authentication point 110” may be provided by another information configuration.

  Here, with reference to FIG. 13, a method of arranging “reproduction authentication points 110” (see FIG. 12) at predetermined time intervals will be described. FIG. 13A shows a temporal arrangement of “reproduction authentication point 110” in the present embodiment. The “reproduction authentication point 110” is provided at a point 110a on the time axis in the audiovisual program. In the present embodiment, a predetermined time interval (interval between each point 110a) at which the “reproduction authentication point 110” determined by the audiovisual authentication subject is set at 60 second intervals throughout the program progress time of the audiovisual program. It is stipulated that there is. It should be noted that the “reproduction authentication point 110” installation interval shown in FIG. 13 (a) is an excerpt of a part of the program progress time of the audiovisual program.

  The presence of the “reproduction authentication point 110” including each piece of information as shown in FIG. 12 installed at the time interval shown in FIG. 13A is not noticed by the viewer. However, in consideration of disclosing the present embodiment also to the viewer of the audiovisual program, the information of the predetermined time interval at which the “reproduction authentication point 110” is installed is kept secret from the viewer. It may be provided. For example, as in the example of the arrangement of “reproduction authentication points 110” shown in FIG. 13B, the arrangement interval of “reproduction authentication points 110” provided at a certain period (section) (installed at a certain interval).

Are superimposed and written. At this time, the information of the predetermined time interval (cycle) at which the “reproduction authentication point 110” is set is added to the information of “period information” constituting the information of the “reproduction authentication point 110” by the audio-visual authentication entity. It is provided so as to be recorded encrypted. In the case of the present embodiment, information on the period at which “reproduction authentication point 110” is set as “installation period is 60 seconds” in the information of “period information” constituting the information of each “reproduction authentication point 110”. Is recorded.

  Alternatively, as shown in FIG. 13D, “valid playback authentication point 110” (see FIG. 12) (main signal) and “invalid playback authentication point 110” (see FIG. 12) (dummy signal) Is provided in the period information of “valid reproduction authentication point 110” (main signal) as “period 60” as information of “period information” constituting “valid reproduction authentication point 110” (main signal). It is only necessary to record information such as “valid reproduction authentication point in seconds”. On the other hand, in the period information of “invalid reproduction authentication point 110” (dummy signal), “invalid reproduction period of 15 seconds” is also included as information of “period information” constituting “invalid reproduction authentication point 110” (dummy signal). It is sufficient to record information such as “reproduction authentication point”.

  Returning to FIG. 11, the audiovisual terminal 60 will be described. The reproduction detection means 62 shown in FIG. 11 is provided at predetermined time intervals in the audiovisual program by the program providing entity that provides the audiovisual program from the information of the audiovisual program reproduced by the reproduction operation using the reproduction means 61 by the viewer. (In the present embodiment, “reproduction authentication point 110”) (see FIG. 12), which is a signal that defines the program progress time of an audiovisual program provided (in a fixed period of 60 seconds with respect to the program progress time). Is an information processing apparatus for detecting In the present embodiment, when the viewer views the audiovisual program at the standard playback speed, the playback detection means 62 detects “playback authentication points 110” at intervals of 60 seconds.

  Alternatively, the playback detection means 62 shown in FIG. 11 may use “valid playback authentication points 110 (see FIG. 12)” (main signal) (see FIG. 13D) and “invalid playback authentication points 110” (see FIG. 13) for audiovisual programs. When a “dummy signal” (see FIG. 13D) is provided, both “valid reproduction authentication point 110” (main signal) and “invalid reproduction authentication point 110” (dummy signal) are detected. What is necessary is just to provide in. However, it may be provided so that only the “valid reproduction authentication point 110” (main signal) is selected and detected by the reproduction detection means 62. The “valid playback authentication point 110” (main signal) is encrypted and recorded by the audio-visual authentication subject in the information of “period information” (see FIG. 12) that is information constituting the “playback authentication point 110”. The information can be identified and detected by referring to the period information of “valid reproduction authentication point 110” (main signal).

  The clock 63 shown in FIG. 11 is provided so as to output the time when the “reproduction authentication point 110” (see FIG. 12) is detected by the reproduction detection means 62. The time output by the clock 63 is provided so as to be recorded in the “detection time” (see FIG. 12) constituting the “reproduction authentication point 110”. In the present embodiment, when the viewer views the audiovisual program at the standard reproduction speed, the clock 63 outputs “detection time” at intervals of 60 seconds.

  Alternatively, the clock 63 shown in FIG. 11 may be used for audiovisual programs such as “valid playback authentication point 110 (see FIG. 12)” (main signal) (see FIG. 13D) and “invalid playback authentication point 110” (dummy signal). ) (See FIG. 13D), the playback detection means 62 detects both “valid playback authentication point 110” (main signal) and “invalid playback authentication point 110” (dummy signal). It is good also as what is provided so that time may be output when it detects. However, the clock 63 may be selected so that only the “valid reproduction authentication point 110” (main signal) is selected and the time is output. The “effective playback authentication point 110” (main signal) is information that is encrypted and recorded by the audiovisual authentication subject in the information of “period information” that is information constituting the “playback authentication point 110”. It can be identified by referring to the period information of the valid reproduction authentication point 110 ”(main signal).

  Further, the transmission means 65 shown in FIG. 11 transmits the “reproduction authentication point 110” (see FIG. 12) to the audiovisual to transmit to the audiovisual authentication entity that authenticates that the viewer is viewing the audiovisual program normally. An information communication device that transmits to the authentication subject. Specifically, the transmission means 65 is a wireless information communication device (wireless LAN communication device (router)) (not shown) connected to a public wireless LAN (not shown). In the present embodiment, the transmission means 65 transmits the “reproduction authentication point 110” to the audiovisual authentication entity at intervals of 60 seconds.

  Alternatively, the transmission means 65 may use “valid reproduction authentication point 110 (see FIG. 12)” (main signal) (see FIG. 13D) and “invalid reproduction authentication point 110” (dummy signal) (see FIG. 12) for the audiovisual program. 13 (d)) is provided, the audiovisual authentication entity having both the “valid reproduction authentication point 110” (main signal) and the “invalid reproduction authentication point 110” (dummy signal). It is good also as what is provided so that it may transmit to the system 80 (refer FIG. 16). However, it is also possible to provide the transmission means 65 so that only the “valid reproduction authentication point 110” (main signal) is selected and transmitted. The “effective playback authentication point 110” (main signal) is information that is encrypted and recorded by the audiovisual authentication subject in the information of “period information” that is information constituting the “playback authentication point 110”. It can be identified by referring to information on the period of installation of the effective reproduction authentication point 110 ”(main signal).

  However, the transmission of information to the audiovisual authentication system 80 (see FIG. 16) by the transmission means 65 shown in FIG. 11 is performed by the audiovisual authentication system 40 (see FIG. 1) of the audiovisual terminal 20 (see FIG. 1). Similar to the transmission of information to (see FIG. 8), the information to be transmitted is recorded by the recording means 64 without transmitting information while the viewer is viewing the audiovisual program. It may be configured to transmit information to the audiovisual authentication system 80 at once after the program has been played back.

  The viewing analysis unit 66 shown in FIG. 11 is an information processing apparatus that analyzes the history of the playback operation of the viewer from two or more “time when the playback authentication point 110 (see FIG. 12) is detected”. In addition, the transmission unit 65 further uses the “playback operation history (audiovisual terminal) 111a” (see FIG. 14) analyzed and output by the viewing analysis unit 66 in order to authenticate the viewing of the audiovisual program by the viewer. It is provided to transmit to the authentication subject.

  The viewing analysis means 66 shown in FIG. 11 includes the “reproduction authentication point 110” that is encrypted and recorded by the audiovisual authentication entity in the information of “periodic information” constituting the “reproduction authentication point 110” (see FIG. 12). It is provided to decode and refer to information on the installed period. In addition, the viewing analysis unit 66 arranges the “reproduction authentication points 110” in the order of the “authentication ID” numbers recorded in the “authentication ID” information constituting the “reproduction authentication points 110”, and the “reproduction authentication points 110”. Is provided so as to integrate the period. Therefore, the viewing analysis means 66 can calculate the program progress time of the audiovisual program in the time interval defined by two or more valid “reproduction authentication points 110”.

  Alternatively, the viewing analysis means 66 may include “valid playback authentication point 110 (see FIG. 12)” (main signal) (see FIG. 13D) and “invalid playback authentication point 110” (dummy signal) (for the audiovisual program). 13 (d)) is provided, the “periodic information” constituting “effective playback authentication point 110” (main signal) is encrypted and recorded by the audiovisual authentication subject “ By decoding and referring to the information on the period in which the “valid reproduction authentication point 110” (main signal) is installed, only the information on the period in which the “effective reproduction authentication point 110” (main signal) is installed is accumulated. What is necessary is just to provide. Alternatively, the viewing analysis unit 66 sets “valid reproduction authentication points 110” in the order of the numbers of “authentication IDs” stored in the information of “authentication ID” constituting “valid reproduction authentication points 110” (main signal). (Main signals) may be arranged side by side so as to integrate the period in which “valid reproduction authentication points 110” (main signals) are installed. Also in this case, the viewing analysis means 66 can calculate the program progress time of the audiovisual program in the time section defined by two or more “valid playback authentication points 110” (main signal).

  On the other hand, the time when the reproduction detection means 62 output by the clock 63 shown in FIG. 11 detects the “reproduction authentication point 110” (see FIG. 12) is the “detection time” that constitutes the “reproduction authentication point 110” (FIG. 12). Information). When the “reproduction authentication point 110” is embedded in the audiovisual program, the “detection time” is blank (blank). The “detection time” detected later is recorded there. The “detection time” can be said to be a program playback time at which the audiovisual program is played by the viewer. Also, the program playback time of the audiovisual program by the viewer according to the playback operation performed by the viewer of the audiovisual program can be defined based on the program playback time recorded at the “detection time”. For this reason, the viewing analysis means 66 is performed by the viewer in the time interval between two or more valid “reproduction authentication points 110” (the same applies to “valid reproduction authentication points 110” (main signal)). The program playback time of the audiovisual program by the viewer following the playback operation can be calculated. Further, the viewing analysis means 66 compares the program progress time of the audiovisual program recorded in the “reproduction authentication point 110” with the program playback time of the audiovisual program by the viewer, so that the viewer operates the playback means 61. Thus, it is possible to calculate at what playback speed (at what speed playback speed) the audiovisual program was viewed.

  An example in which the viewing analysis unit 66 shown in FIG. 11 calculates the history of playback operations by the viewer will be described. For example, a rear “reproduction authentication point 110” is configured in a time interval between two “reproduction authentication points 110” (see FIG. 12) (also “valid reproduction authentication point 110” (main signal)). The information recorded by encrypting the information of “period information” by the audiovisual authentication subject is “installation cycle is 60 seconds” (“valid playback authentication point 110 (main signal) installation cycle is 60 seconds”). ). In this case, it can be said that the program progress time of the audiovisual program in the time interval between the two “reproduction authentication points 110” is 60 seconds. On the other hand, it is assumed that the time interval (that is, the program playback time by the viewer) recorded in the “detection time” (see FIG. 12) constituting two valid “playback authentication points 110” is 30 seconds. In this case, the viewing analysis unit 66 compares the program progress time of the audiovisual program with the program playback time by the viewer, and the viewer plays the audiovisual program at the double speed playback speed. The history of the playback operation of the audiovisual program by the viewer (“playback operation history”) (playback speed) can be calculated.

  Further, the viewing analysis means 66 shown in FIG. 11 can refer to the information of “authentication ID” which is information constituting the “reproduction authentication point 110” (see FIG. 12). In the information of “authentication ID” that is information constituting “reproduction authentication point 110”, consecutive numbers in ascending order are given to all “reproduction authentication points 110” through one audiovisual program. For this reason, the viewing analysis means 66 can identify the part that the viewer has viewed and viewed the audiovisual program. For this reason, the viewing analysis unit 66 plays back the history of the audiovisual program playback operation by the viewer, for example, the viewer plays back the audiovisual program of 90 minutes in the program progress time at the standard playback speed for the first 30 minutes. It is possible to clarify the playback speed at which the viewer has watched the audiovisual program through one audiovisual program, such as playing at a double speed for 30 minutes and playing at the quadruple speed for the remaining 30 minutes. .

  In the present embodiment, the viewing analysis means 66 defines the history of the playback operation by the viewer (for example, “playback at 2 × speed”) by the “playback authentication point 110” (see FIG. 12). The information of “playback operation history (audiovisual terminal) 111a” (see FIG. 14) is output in a one-to-one relationship with “playback authentication point 110” corresponding to the part of the audiovisual program (program progress time). Is provided. Note that the information of “playback operation history (audiovisual terminal) 111a” is also individually identified based on the information of “authentication ID” given by “playback authentication point 110”, similarly to the information of “playback authentication point 110”. It is provided so that it can. Therefore, regardless of the viewing order of the portions of the audiovisual program by the viewer, the information of “reproduction operation history (audiovisual terminal) 111a” can be sequentially output corresponding to the information of “reproduction authentication point 110”. .

  For this reason, the viewing analysis means 66 shown in FIG. 11, regardless of the detection order of the “reproduction authentication point 110” (see FIG. 12), for example, It seems that it started to watch at the double speed playback speed from the last 30 minutes part of the audiovisual program, and then returned to the first part of the audiovisual program and watched the remaining 60 minutes of the audiovisual program part at the standard playback speed. Even in such a case, it is possible to calculate the history of the playback operation by the viewer.

The audiovisual authentication entity can grasp the reproduction operation of the audiovisual program by the viewer by referring to the “reproduction operation history (audiovisual terminal) 111a”.

  The information of “reception time 112” constituting “authentication record 115” shown in FIG. 14 includes the audiovisual terminal operated by the viewer output by the clock 84 (see FIG. 16) included in the audiovisual authentication system 80 (see FIG. 16). 60 (see FIG. 11) is provided so that the time at which the reception means 83 (see FIG. 16) receives the “reproduction authentication point 110” (see FIGS. 12 and 13) transmitted from 60 (see FIG. 11) is recorded. As will be described in detail later, the audiovisual authentication system 80 can authenticate the viewing of the audiovisual program by the viewer based on “the time when the reproduction authentication point 110 is received”.

  The information of “recording time 113” constituting “authentication record 115” shown in FIG. 14 includes the audiovisual terminal 60 (see FIG. 16) received by the receiving means 83 (see FIG. 16) included in the audiovisual authentication system 80 (see FIG. 16). 11 (see FIG. 11) recorded by the recording means 64 (see FIG. 11) and outputted by the reproduction detection means 62 (see FIG. 11) output from the clock 63 (see FIG. 11). The time when “is detected” is recorded. As will be described in detail later, the audiovisual authentication system 80 can authenticate the viewing of the audiovisual program by the viewer based on the “time when the reproduction authentication point 110 is detected” recorded by the audiovisual terminal 60.

  The “viewing authentication” information included in the “authentication record 115” illustrated in FIG. 14 includes “viewing authentication (audiovisual terminal) 114a” based on the “playback operation history 111a” transmitted from the audiovisual terminal 60 (see FIG. 11). Is recorded. The audiovisual authentication entity can authenticate the viewing of the audiovisual program by the viewer based on “viewing authentication (audiovisual terminal) 114a” based on “playback operation history 111a”.

  When the “viewing authentication” is output by the viewing authentication means 67 (see FIG. 11) included in the audiovisual terminal 60 (see FIG. 11), the audiovisual authentication system 80 (see FIG. 16) of the audiovisual authentication entity is provided. The viewing authentication means 86 (see FIG. 16), which will be described in detail later, is not necessary. Since these functions may be realized by the cooperation of the audiovisual terminal 60 and the audiovisual authentication system 80, the audiovisual terminal 60 and the audiovisual authentication system 80 may share the functions as appropriate. But it is good also as what verifies information processing mutually as what is provided so that the same information processing may be performed in both the audiovisual terminal 60 and the audiovisual authentication system 80.

  In another embodiment shown in FIG. 18, an audiovisual terminal 60a in which the function of the audiovisual terminal 20 (see FIG. 1) is incorporated into the audiovisual terminal 60 (see FIG. 11) can be configured. In this case, the audiovisual terminal 60 a can be provided so as to further include the operation instruction means 22, the motion sensor 23, and the signal converting means 24 provided in the audiovisual terminal 20.

The audio-visual authentication subject is strictly controlled by the audio-visual authentication subject without frequently requesting a predetermined operation from the viewer by allowing the viewer of the audio-visual program to reproduce and view the audio-visual program using the audio-visual terminal 60a. You can authenticate viewing.

  Specifically, when the viewer uses the audiovisual terminal 60a shown in FIG. 18, the viewer uses the audiovisual terminal 60a even if the viewer does not frequently request a predetermined operation. As for the audiovisual program being played back, the “playback authentication point 110” (see FIGS. 12 and 13) can be used to authenticate viewing. For this reason, the audio-visual authentication subject does not need to frequently request a response operation from the viewer to authenticate the viewing. For example, when the viewer views the audiovisual program using the audiovisual terminal 60a, the audiovisual authentication entity determines the number of times of viewing authentication performed by requesting a predetermined operation from the viewer, the beginning of the audiovisual program, the audiovisual program. It is possible to reduce the number of times about three times at the center of the program progress time and the end of the audiovisual program.

  On the other hand, when the viewer uses the audiovisual terminal 60a shown in FIG. 18, the audiovisual authentication entity not only performs viewing authentication using the “reproduction authentication point 110” (see FIGS. 12 and 13). Since the viewer can be requested to perform a predetermined operation for viewing authentication, the viewing can be performed more strictly compared to the viewing authentication in which only the viewing authentication using the “reproduction authentication point 110” is performed. Can be authenticated.

  Here, a control program for controlling the audiovisual terminal 60 (see FIG. 11) will be described with reference to FIG.

Subsequently, “playback” is a signal that demarcates the program progress time provided at predetermined time intervals in the audiovisual program by the program providing entity that provides the audiovisual program from among the audiovisual programs reproduced by the playback operation by the viewer. The “authentication point 110” (see FIGS. 12 and 13) is detected using the reproduction detection means 62 (see FIG. 11) (step N02). Subsequently, using the clock 63 (see FIG. 11), the reproduction detection means 62 outputs “the time when the reproduction authentication point 110 is detected”. Further, “the time when the reproduction authentication point 110 is detected” is recorded in the “reproduction authentication point 110” (step N03). Subsequently, the “reproduction authentication point 110” detected by the reproduction detection means 62 and the clock 63 output to transmit to the audiovisual authentication entity that authenticates that the viewer is viewing the audiovisual program normally. The “time when the playback authentication point 110 is detected” is transmitted to the audiovisual authentication system 80 (see FIG. 16) possessed by the audiovisual authentication entity using the transmission means 65 (see FIG. 11) (step N04).

  The execution control processing of the audiovisual terminal 60 (see FIG. 11) using the control program shown in FIG. 15 is provided so as to include auxiliary control or execution processing in addition to the main execution processing described above. . First, using the viewing analysis means 66 (see FIG. 11), there is provided a process (step N11) for outputting a “playback operation history (audiovisual terminal) 111a” (see FIG. 14), which is a history of playback operations by the viewer. ing. Further, the viewing authentication unit 67 (see FIG. 11) is used to authenticate the viewing of the audiovisual program by the viewer based on the “playback operation history (audiovisual terminal) 111a” analyzed by the viewing analysis unit 66. A process (step N12) for outputting "terminal" 114a "(see FIG. 14) is provided.

  Alternatively, in another embodiment, the control process performed by the control program (see FIG. 7) for controlling the audiovisual terminal 20 (see FIG. 1) is performed on the control program shown in FIG. 15 for controlling the audiovisual terminal 60 (see FIG. 11).
