Description

  The present invention receives multimedia contents sent by data broadcasting, such as a portable telephone having a terrestrial digital broadcast receiving function, and presents the received multimedia contents on a display device and data on a communication server. The present invention relates to a terrestrial digital broadcast receiving portable terminal having means for transmitting.

  In a data broadcasting service for portable terminals of digital terrestrial broadcasting, a program is being studied in which an answer to a quiz is transmitted to a communication server using a communication function from a BML document that is multimedia content transmitted by broadcasting. Conventionally, when transmission to a communication server occurs, the user is asked to confirm consent by a normal dialog or the like because a communication fee is charged or user information is leaked to the outside.

  However, if an agreement is confirmed every time an answer is made in a quick press quiz or the like, the operation is troublesome for the user, and extra time is required until the answer is transmitted.

  This will be described more specifically. In terrestrial digital broadcasting, a channel corresponding to a channel in conventional analog broadcasting is called a “service”. In addition, a program corresponding to a program divided in time in each service is called an “event”.

  One service is composed of components called “components”. Components are roughly classified into “video components”, “audio components”, and “data components”. Among these, data content is transmitted by the data component. A data content divided in time is called a “data event”. Note that “event” and “data event” may or may not correspond to one to one.

  The data content is composed of a document described in BML (Broadcast Markup Language) and mono-media data such as an image, and one data content includes one or a plurality of BML documents.

  On the other hand, in the multimedia content composition model based on the BML document, the concept of scope is introduced, and four scopes are defined. The mapping shown in Table 1 is performed between the scope and the physical data.

  That is, data belonging to the same service is expressed as being within the scope of the same content group, and data belonging to the same data event is expressed as being within the scope of the same document group. Also, the scope is in an inclusive relationship, and if it falls outside the higher scope, it goes without saying that it falls outside the lower scope. These inclusion relationships are shown in FIG.

  On the other hand, the service and event have an inclusive relationship of “service 成 り event”.

  FIG. 2 shows a case where a user participation type quiz program is viewed and an answer to the quiz is transmitted to the communication server. 2 shows a display screen, in which the upper part of the display screen is a moving image display area (AV data display area) and the lower part of the display screen is a data display area (multimedia content display area). When the user selects one number from 1 to 4 on the screen on the left side of 2, a dialog (user consent confirmation screen) for confirming whether or not to perform data transmission is displayed as shown on the right side of FIG. When the user selects the “OK button” in this dialog, the response is sent to the communication server.

  FIG. 3 shows a processing procedure when a data transmission factor occurs.

  When a factor for data transmission occurs, a user consent confirmation screen is displayed (step S1). If the user agrees (when the “OK button” is selected) (YES in step S2), the user consent confirmation screen is deleted (step S3) and data transmission is executed (step S4). And this process is complete | finished.

  When the user does not agree (when the “CANCEL button” is selected) (NO in step S2), the user consent confirmation screen is deleted (step S5). And this process is complete | finished, without performing data transmission.

  That is, conventionally, every time a factor of data transmission occurs, user consent is required. For this reason, the operation is troublesome for the user, and extra time is required until data is transmitted.

  The present invention provides digital terrestrial broadcast reception that can prevent the consent confirmation screen from being presented when data transmission to the communication server is performed while presenting multimedia content within a predetermined scope. An object is to provide a portable terminal.

  In addition, the present invention makes it possible to prevent the consent confirmation screen from being presented when executing data transmission to the communication server while presenting multimedia content within a predetermined scope. If the consent confirmation screen is not presented when executing data transmission, the consent confirmation indicates whether or not the consent confirmation screen is presented when executing data transmission by multimedia content. It is an object of the present invention to provide a portable terminal for receiving terrestrial digital broadcasting that can return to a state in which a screen is presented.

  According to the first aspect of the present invention, there is provided means for receiving multimedia content sent by data broadcasting, presenting the received multimedia content on a display device, means for transmitting data to a communication server, and data transmission to the communication server. Before the execution, the consent confirmation screen for confirming the execution consent is presented to the user, and the consent is obtained in the digital terrestrial broadcast receiving portable terminal having means for executing the data transmission only when the user's consent is obtained. After that, on the confirmation screen, the means for inputting whether or not consent confirmation is omitted when transmitting data to the communication server within the scope of the predetermined scope, and the execution consent is confirmed on the consent confirmation screen and Thereafter, if an input to omit consent confirmation is made within the scope of the predetermined scope, While presenting multimedia content within the scope, it is provided with means for preventing the user from presenting the consent confirmation screen for confirming the consent of execution when data transmission is performed. And

  In the invention described in claim 2, in the invention described in claim 1, consent to execute is confirmed on the consent confirmation screen, and thereafter, an input indicating that consent confirmation is omitted within a predetermined scope is performed. In this case, there is provided means for displaying on a part of the screen that the consent confirmation is omitted while the multimedia content within the scope of the predetermined scope is presented. It is characterized by that.

  According to a third aspect of the present invention, in the first or second aspect of the present invention, the predetermined scope refers to a content group, a content, a document group and a document, and a digital broadcast in a multimedia content configuration model using a BML document. One of the programs (events) defined by the program arrangement information transmitted as a signal is arbitrarily selected.

  The invention according to claim 4 is the invention according to claim 1 or 2, wherein the predetermined scope is a program (event), and when the consent confirmation screen is displayed, the program (event ) Is displayed on the consent confirmation screen.

  The invention according to claim 5 is the invention according to claim 4, characterized in that the program name of the program is included in the information related to the program (event) currently presented.

  According to a sixth aspect of the present invention, in the present invention according to the fourth to fifth aspects of the present invention, the information relating to the currently presented program (event) includes a start time and / or an end time of the program. It is characterized by that.

  The invention according to claim 7 is the invention according to any one of claims 1 to 6, wherein the consent confirmation is performed by multimedia contents when the consent confirmation screen is not presented when data transmission is executed. When an instruction to invalidate the state that does not present the screen is given, the state whether or not the consent confirmation screen is presented when executing data transmission is changed to the state that the consent confirmation screen is presented. A returning means is provided.

  According to the present invention, while presenting multimedia content within a predetermined scope, it is possible to prevent the consent confirmation screen from being presented when data transmission to the communication server is executed.

  Further, according to the present invention, it is possible to prevent the consent confirmation screen from being presented when data transmission to the communication server is performed while multimedia content within the range of the predetermined scope is being presented. In addition, when it is in a state where the consent confirmation screen is not presented when executing data transmission, depending on the multimedia content, whether to present the consent confirmation screen when executing data transmission, It is possible to return to a state in which the consent confirmation screen is presented.

  Hereinafter, with reference to FIGS. 4 to 10, an embodiment in which the present invention is applied to a portable telephone having a digital terrestrial broadcast receiving function will be described.

  FIG. 4 shows the configuration of a terrestrial digital broadcast receiving unit in a portable telephone having a terrestrial digital broadcast receiving function.

  The terrestrial digital broadcast wave is sent to the tuner 2 via the terrestrial antenna 1, and high frequency processing and demodulation are performed. The output from the tuner 2 is sent to the DEMUX circuit 3 where the packet is decoded.

  In the DEMUX circuit 3, the packets are classified into AV streams, multimedia contents, and program arrangement information. Program sequence information is various information related to a broadcast program transmitted in digital broadcasting, and is defined in ARIB STD-B10. Among the program sequence information, the event information table (EIT) contains information such as the event name, event start time, and event duration for events (programs) included in each service (channel). . The AV stream sorted by the DEMUX circuit 3 is sent to the AV decoder 4. The multimedia contents and program arrangement information sorted by the DEMUX circuit 3 are sent to the system controller 20.

  In this example, the system controller 20 includes a ROM 21 that stores programs and the like, a RAM 22 that stores necessary data, and a nonvolatile memory 23 that stores necessary data.

  The system controller 20 stores the multimedia content and program arrangement information sent from the DEMUX circuit 3 in the RAM 22. An operation signal from the operation unit 12 is input to the system controller 20.

  The system controller 20 sends information for channel selection to the tuner 2 and the DEMUX circuit 3. Further, the system controller 20 sends a graphic control signal for displaying multimedia contents, various operation screens, and the like on the LSD 8 to the graphic display circuit 14. The graphic display circuit 14 generates display data such as multimedia contents and various operation screens, and sends it to the multiplexer (combining circuit) 6 as a graphic signal. The graphic signal sent to the multiplexer (synthesis circuit) 6 is sent to the LCD 8 via the video output circuit 7.

  The AV decoder 4 decodes the AV stream sent from the DEMUX circuit 3. The video signal obtained by the AV decoder 4 is sent to the LCD 8 via the video processing circuit 5, the multiplexer 6 and the video output circuit 7.

  The audio signal obtained by the AV decoder 4 is sent to the speaker 11 via the audio processing circuit 9 and the audio output circuit 10.

  Assume that a user-participating quiz program is being viewed and an answer to the quiz is transmitted to the communication server. In this mobile phone, as shown in FIG. 5, when asking for user consent, a user who can select whether to continue to require consent for data transmission or not to ask for consent thereafter. The consent confirmation screen is displayed. In other words, in addition to the “OK button” and “CANCEL button”, a check box for selecting whether or not to display this screen is displayed on the user consent confirmation screen.

  If the user chooses not to ask for consent afterwards (if the check box is checked), the multimedia content being presented is again within the scope of the preset scope. Control is performed so that the user's consent is not confirmed even when data is transmitted to the communication server. That is, the fact that consent has been confirmed is stored as a flag (consent confirmation flag) F. Further, as shown in FIG. 6, a content indicating that the consent has been confirmed is displayed on a part of the screen.

  Note that whether to use a BML document, a document group, a content, a content group, or an event as a scope for defining a range in which consent confirmation is omitted is set in advance by the broadcast service to be received. The factors that cause the multimedia content currently being presented to deviate from the preset scope differ depending on the type of the set scope.

  For example, when the set scope is a content group, the scope is removed by service tuning by the user. Further, when the set scope is a content or a BML document, the scope is removed by document transition (selecting a link to another BML document) by a user's key operation.

  When the set scope is a document group, the scope is removed due to a change in data int ID included in DII (Download Info Indication) which is one of transmission signals. When the set scope is an event, the scope is removed due to a change in the event ID for the current event included in an EIT (Event Information Table) which is one of the transmission signals.

  If the multimedia content currently being presented is out of the preset scope, the consent confirmation flag F is set in order to confirm the user's consent when transmitting data to the communication server again. Clear it.

  FIG. 7 shows the operation of the mobile phone when a data transmission factor occurs.

  When a data transmission factor occurs, it is determined whether or not the user consent confirmed flag F is set (F = 1) (step S11). If the user consent confirmation flag F is not set (F = 0), a user consent confirmation screen as shown in FIG. 5 is displayed (step S12).

  When the user does not agree on the user consent confirmation screen (when “CANCEL button” is selected) (NO in step S13), the user consent confirmation screen is deleted (step S14). And this process is complete | finished, without performing data transmission.

  When the user agrees on the user consent confirmation screen (when the “OK button” is selected) (YES in step S13), it is determined whether or not a check indicating that confirmation will not be performed later is put on the user consent confirmation screen. (Step S15). If the user consent confirmation screen is not checked to indicate that confirmation will not be performed thereafter, the user consent confirmation screen is deleted (step S16), and then data transmission is executed (step S20). And this process is complete | finished.

  If it is determined in step S15 that a check indicating that confirmation will not be performed thereafter has been entered, the user consent confirmation screen is deleted (step S17). In addition, the user consent confirmation flag F is set (F = 1), and information for specifying a scope range for defining a range in which consent confirmation is omitted (currently presented program (event), present Information on the multimedia content being presented is stored (step S18). Moreover, as shown in FIG. 6, the display of the content indicating that the consent has been confirmed is turned ON (step S19). Then, data transmission is executed (step S20), and the current process is terminated.

  FIG. 8 shows a procedure for resetting the consent confirmation flag F, which is executed when the consent confirmation flag F is set.

  When the user consent confirmed flag F is set, information for specifying a scope range for specifying a range for omitting the consent confirmation stored when the user consent confirmed flag F is set Whether or not the multimedia content being presented is out of the scope of the scope is monitored based on the scope type set to define the scope for omitting the consent confirmation (step S31). The method for determining whether or not the multimedia content currently being presented is out of the scope of the preset scope differs depending on the scope type set as described above.

  When it is determined that the multimedia content being presented is out of the scope, the user consent confirmation flag F is reset (step S32), and the display of the content indicating consent confirmation is turned off. (Step S33). Then, the reset process of the consent confirmed flag F is terminated.

  By the way, if the scope for specifying the scope for omitting consent confirmation is a content group (service), the user knows that the scope is within the same scope until the channel selection operation is performed. If you agree not to confirm the data transmission, you can recognize how long that state will continue.

  On the other hand, if the scope for specifying the range for omitting the consent confirmation is a BML document, document group, content, or event, the user cannot recognize that the scope has been switched. It is not possible to recognize how long a state of no confirmation for data transmission to the communication server will continue.

  Therefore, when the scope for specifying the range where consent confirmation is omitted is an event (program), as shown in FIG. 9, when the user consent confirmation screen is displayed, the event of the event currently being presented is displayed. It is preferable to display the name, the start time and the end time of the event. In this way, if the user agrees not to confirm on the user consent confirmation screen, the user can confirm how long the state will continue.

  Further, a function (consent invalidation instruction function) for resetting the user consent confirmed flag F is described in the data content, and when this function is called on the mobile phone side, the user consent confirmed flag F may be reset. This will be described by taking as an example the case where the scope for defining the range for omitting consent confirmation is an event.

  For example, in a viewer-participation-type quiz program, when data is first transmitted to the communication server, the user agrees not to confirm later. In a CM inserted in the middle of an event, for example, a case is assumed in which a user's name, address, etc. are transmitted to a communication server different from the quiz in order to request a catalog of a certain product. In such a case, the user may agree not to ask for confirmation regarding the transmission of the answer to the quiz, but may not intend to agree not to ask for confirmation even regarding the data transmission to the CM.

  In view of this, in the data content, the user's consent for not requesting confirmation can be invalidated before data transmission to the CM. Specifically, in the script included in the BML document describing the data content, for example, by calling a consent invalidation instruction function as described below, the user's consent for not requesting confirmation is invalidated. In other words, the following agreement invalidation instruction function is described in the BML document.

Number invalidateUserPermission ()
Argument None Return value 1: Success
NaN: Failure

  FIG. 10 shows a procedure for resetting the consent confirmation flag F based on the consent invalidation instruction function.

  When the script process is executed, it is determined whether or not the consent invalidation instruction function has been called (step S41). When the consent invalidation instruction function is called, the user consent confirmation flag F is reset (step S42), and the display of the content indicating that the consent has been confirmed is turned off (step S43).

  In the present embodiment, the form in which a check box is displayed on the consent confirmation screen has been described as a method for the user to input that consent confirmation is omitted within the scope of the predetermined scope. Instead of displaying, three buttons such as “OK (not confirmed later)”, “OK (only once)”, “CANCEL” are displayed as selection buttons, and “OK (not confirmed later)” is displayed. When selected, consent confirmation may be omitted within the scope of a predetermined scope. Moreover, you may confirm a user's intention by another method.
