Abstract

<P>PROBLEM TO BE SOLVED: To provide a means for displaying CM inserted into content with respect to a sponsor in a securer manner. <P>SOLUTION: A recording/playback unit 100 detects the start position and the end position of the CM included in the content, generates CM position-history information, constituted of flags that indicate the positions and the possibility/impossibility of playback, so as to manage whether the CM is already played back. When a viewer views the contents, by reference to the CM position-history information, the CM that is already played back is skipped automatically. Also, when the viewer instructs a tentative stop or the display of a menu screen, the content is tentatively stopped according to the situation, and by referring to the CM position-history information, the CM which has not been played back is played back. Furthermore, the CM position-history information is updated, as needed, and after the lapse of a certain time, the repeated playback of CM and the redisplay of CM having been played back are performed. <P>COPYRIGHT: (C)2009,JPO&INPIT

Description

  The present invention relates to a playback device for playing back content, and more particularly to a playback device for a function of playing a commercial message included in content.

  In recent years, digitization of broadcast waves has progressed, and it has become possible to record received programs as digital contents on a recording / playback apparatus without deterioration. Some of these recording / playback apparatuses have a function of skipping a commercial message (hereinafter referred to as CM) portion during playback of the main content, and the user can use this function to perform CM at any timing. Can be watched or skipped.

  However, it is not preferable for the advertiser not to play the CM because the advertisement effect is reduced. Therefore, a technique is disclosed that includes means for detecting CMs in the content, separates and records the main part and the CM in advance, reproduces the CMs stored in a batch when the content reproduction is paused, and does not reproduce it during the main part reproduction. (For example, refer to Patent Document 1).

JP 2006-50169 A

  However, in the conventional method, since the CM is displayed only at the time of the pause or the CM is played back before and after the main content, the opportunity to play the CM is not provided during the playback of the main content. In other words, if the user does not perform a pause operation, the CM may not be played back, and the user can only expect the user to pause, and the advertiser can obtain the advertising effect of the CM inserted in the content. There is a problem that can not be. Also, when displaying the CMs collectively before and after the main part, if the user fast-forwards at the beginning of the main part and stops at the end of the main part, the CM is not reproduced.

  In addition, while usually skipping CMs, you may want to view the CM that was originally inserted during playback of the main part, or display the CM once viewed after a certain period of time, or if the previously played CM is paused There may be a user's request that only playback is performed.

  One of the objects of the present invention is to provide a means for more reliably displaying the CM inserted in the content to the advertiser.

  Another object of the present invention is to provide user-friendly content reproduction means for users.

  One embodiment of the present invention will be described, for example, as in the claims.

  According to the present invention, even when a viewer skips a CM included in the content by an operation such as fast-forwarding while viewing the content, the CM is displayed to the viewer by automatically playing the CM during the pause. Can increase opportunities to do.

  Further, according to the present invention, the CM effect expected by the content distribution source can be promoted.

  In addition, according to the present invention, a CM that has been played once is automatically skipped during playback of the main part, so that the main part can be played back while the viewer concentrates on watching the main part at the time of content playback.

Embodiments of the present invention will be described below with reference to the drawings. The present invention is not limited to the illustrated example.
Example 1
The invention according to the first embodiment will be described with reference to FIG. FIG. 1 shows a configuration of a recording / playback apparatus 100 that stores and plays back a plurality of contents. This recording / reproducing apparatus can receive various broadcast programs, and record and reproduce these programs. Here, the broadcast program is not limited to a television broadcast wave such as a terrestrial wave or a satellite wave, but may be a broadcast or download content distributed via a communication line.

  The recording / playback apparatus 100 includes a tuner processing unit 101, an input unit 102, a recording unit 103, a recording medium 104, a CM position and / or history information recording medium 105, a timer unit 106, a CM detection unit 107, a playback unit 108, and a child screen generation. Unit 109, control screen generation unit 110, screen synthesis unit 111, audio output unit 112, video output unit 113, control unit 150, and temporary recording medium 151.

  The tuner processing unit 101 is a part that receives a broadcast wave, converts it into a video signal, and selects a desired channel. Examples of broadcast waves include digital broadcast waves and analog broadcast waves.

  The input unit 102 is adapted to receive an input signal by a remote control operation from a user and convert it into a control signal. The recording unit 103 performs recording control for recording the received content on the recording medium 104. The recording medium 104 records content information. Each content is stored in a format such as an MPEG file, for example, and is written and read as necessary. For example, a built-in or detachable HDD, an optical disk, a memory card, a nonvolatile memory, and the like are conceivable. In addition to being used alone, a hybrid form in which these are combined is also conceivable.

  The CM position and / or history information recording medium 105 stores CM insertion position information included in the content recorded on the recording medium 104, reproduction history information, flag information for determining whether to reproduce, or the like. The timer unit 106 performs time measurement for managing time information and elapsed time information from a specified time.

  The CM detection unit 107 reads the information of the content read and reproduced by the reproduction unit 108 from the recording medium 104, and detects the start and end positions of the CM included in the content using a known CM detection method. Yes. The playback unit 108 performs playback control (such as decoding of an encoded video) for playing back the content recorded on the recording medium 104. A plurality of videos can be played back simultaneously.

  The sub-screen generation unit 109 converts the display size of the video signal and generates a screen having an arbitrary size. The control screen generator 110 generates control screens such as operation menus and setting screens.

  The screen synthesis unit 111 controls the video generated by the playback unit 108, the sub-screen generation unit 109, and the control screen generation unit 110, synthesizes them as necessary, and combines them into one video. The audio output unit 112 has a function of outputting the audio decoded by the reproduction unit 108 or a preset audio to a device such as a built-in or external speaker, earphone, headphone, or recording device.

  The video output unit 113 has a function of outputting a video signal. Examples of the output target include various monitors such as an external or built-in cathode ray tube, a liquid crystal panel, a plasma display panel, and an organic EL panel, a recording device, and a communication device for video transmission.

  The control unit 150 is configured to manage and control the operation of each unit in the recording / playback apparatus 100 in an integrated manner. The temporary recording medium 151 is attached to the control unit 150 and temporarily records information necessary for smooth processing.

  The invention according to the first embodiment can be realized by the above-described configuration. However, the configuration in which the CM position and / or history information recording medium 105 is integrated into the recording medium 104 and collectively managed, or the tuner processing unit 101 is used. It is good also as a structure provided with two or more.

  Next, a configuration example of information including a CM insertion position and a reproduction history included in the content recorded on the recording medium 104 will be described with reference to FIG. Here, it is assumed that each content recorded on the recording medium 104 has a configuration in which a plurality of CMs are inserted between the main contents. In this embodiment, three contents are included in the main contents as in the content 250 shown in FIG. Assume that it includes two CM parts (252, 253, 254).

  In the present embodiment, the CM insertion position included in each content recorded on the recording medium 104 is detected, and the CM position and / or history information 200 is created. Then, the CM position and / or history information 200 is stored in the CM position and / or history information recording medium 105, and the CM playback history is managed using the CM position and / or history information 200 as necessary. ing.

  The CM position / playback history information 200 includes elements such as a CM start position 201, a CM end position 202, a previous playback date / time 203, and a playback flag 204. The CM start position 201 and the CM end position 202 indicate the start time and end time of the CM included in the content. The previous playback date and time 203 is the date and time when the CM is played back. The reproduction flag 204 indicates a flag for determining whether or not to reproduce the CM, and for example, values such as “reproduce” and “do not reproduce” are set.

  Here, the CM start position 201 and the CM end position 202 may be specified by time, or may be specified by the number of bytes from the top of the content. When specifying by time, the CM end position 202 may be set by relative time. If the chapter information of the content can be used, it may be specified by such metadata. In addition, other setting values may be added to the reproduction flag 204 as necessary (for example, “always reproduce”).

  When the CM position and / or history information 200 is created for the content 250, it is represented as the CM position and / or history information 210. In the CM position and / or history information 210, CM 252 is associated with CM information 215, CM 253 is associated with CM information 216, and CM 254 is associated with CM information 217.

  A procedure for creating the CM position and / or history information 210 will be described with reference to FIG. The creation of the CM position and / or history information 210 can be executed at an arbitrary timing, and can be performed in any case, for example, at the time of content playback, at the time of content recording, or at the time of standby. In particular, when the CM position and / or history information 210 is created at the time of content playback, one channel is assigned to the content playback, and another channel is assigned to create the CM position and / or history information 210 for the content. In parallel, the CM position and / or history information 210 can be created.

  First, the control unit 150 instructs the playback unit 108 to read the content recorded on the recording medium 104, and starts playback of the content. In the example of the content 250, the main part 251 is reproduced. The playback speed may be the same speed playback or high speed playback. The control unit 150 instructs the playback unit 108 to send information such as audio, video, subtitles, and program auxiliary information played back by the playback unit 108 to the CM detection unit 107. The combination of information to be transmitted is information necessary and sufficient for the CM detection unit 107 to detect the CM (step S301).

  Next, the control unit 150 confirms whether or not the content has reached the end while reproducing the content (step S302). If the end of the content has been reached, the reproduction of the content is stopped (step S309).

  If the content has not reached the end in step S302, the CM detection unit 107 detects the start position of the CM 252 based on the information sent from the reproduction unit 108 (step S303). Then, it is determined whether or not the current playback position is the CM start position (step S304). If the current playback position is not the CM start position as a result of the determination, the process returns to step S302 again (step S304). : No), the control unit 150 continues to detect the CM.

  In step S304, when the current reproduction position reaches the CM 252 (starting from 15′20 ”) and the start of CM is detected (step S304: Yes), the CM detection unit 107 notifies the control unit 150 of CM detection. Upon receiving the CM detection, the control unit 150 receives the playback time or playback position at that time from the playback unit 108, sets the CM position and / or the CM start position 211 in the history information 210, and sets the CM as necessary. The position and / or history information recording medium 105 is recorded (step S305).

  Next, the CM detection unit 107 detects the end position 212 of the detected CM 252 (step S306). Then, it is determined whether or not the reproduction of the CM 252 has yet to be completed (step S307). If the result of the determination is that it has not ended, the process returns to step S306 again to continue detecting the CM end position. In step S307, when the reproduction position reaches the end (16'20 ") of the CM 252 and the end of the CM is detected, the CM detection unit 107 notifies the control unit 150 that the CM 252 has ended.

  Upon receiving the end of the CM 252, the control unit 150 receives the playback time or playback position at that time from the playback unit 108, sets the CM end position 212, and the CM position and / or history information recording medium 105 as necessary. (Step S308). Thereafter, the process returns to step S302, and the reproduction of the main part 255 is continued, and detection of the next CM start portion is continued.

  As described above, the start and end positions of the CM are continuously detected, and when the end of the content 250 is reached in step S302, the control unit 150 instructs the reproduction unit 108 to stop the reproduction of the content 250 (step S309). As a result, as shown in the CM position and / or history information 210, a CM start position 211 and a CM end position 212 are recorded. Also, as the initial setting of CM / position and / or history information, the previous reproduction date / time 213 is not yet defined since it has not actually been viewed, and all the reproduction flags 214 are set to “reproduce”.

  Next, when the viewer pauses while viewing the content 250 stored in the recording medium 104, the CM position and / or history information 210 of the content stored in the CM position and / or history information recording medium 105 is used. A method for reproducing the CM 252 on the pause screen will be described with reference to the flowchart 400 of FIG.

  As a premise, the CM position and / or history information 210 corresponding to the content 250 is read from the CM position and / or history information recording medium 105 in advance by the control unit 150 at the time of starting reproduction, and is transferred to the temporary recording medium 151. It shall be recorded.

  First, the viewer performs a pause operation on the device 100 (for example, presses the pause button on the remote controller) while the main part 251 is being played, and the input unit 102 receives the operation (step S401). The control unit 150 receives a pause input from the input unit 102, controls the playback unit 108, and pauses playback (step S402).

  Next, the control unit 150 instructs the timer unit 106 to start measuring time (step S403). The control unit 150 determines whether or not a predetermined time set in advance has elapsed (step S404), and waits for a predetermined time while displaying a paused video on the screen. This is a waiting time for watching a paused video. You may change this waiting time according to a viewer's setting.

  Here, as a method of measuring and determining the waiting time in steps S403 and S404, the control unit 150 acquires the current time from the timer unit 106, records the time information in the temporary recording medium 151, and the timer unit 106 as needed. There is a method in which the control unit 150 repeatedly compares the time recorded on the temporary recording medium 151 and the current time while acquiring the current time, and waits for a set elapsed time. There is also a method of setting the timer unit 106 so that a notification of the end of the waiting time is sent to the control unit 150 after a specified time has elapsed.

  After a predetermined time has elapsed in step S404 (step S404: Yes), the control unit 150 acquires the CM position and / or history information 210 (see FIG. 2) corresponding to the content 250 being reproduced from the temporary recording medium 151. (Step S405).

  Next, the control unit 150 searches the acquired CM position and / or history information 210 for the presence of CM information with a “playback” flag (step S406). If the CM information with the “reproduce” flag cannot be found in step S406 (step S406: No), the pause is continued without displaying the CM on the screen. When the CM information 215 with the “reproduce” flag is found in step S406, the control unit 150 records the reproduction position at the time of pause acquired from the reproduction unit 108 on the temporary recording medium 151 (step S407).

  Then, the control unit 150 moves the current reproduction position to the reproduction position indicated by the CM position acquired in step S405 and / or the CM start position 211 in the history information 210, and instructs the reproduction unit 108 to perform CM reproduction. (Step S408). The playback unit 108 starts playback of the CM 252 corresponding to the found CM information 215, sends the CM video to the screen composition unit 111, and simultaneously sends the paused main screen to the child screen generation unit 109. At the same time, the CM 252 audio signal is sent to the audio output unit 112. You may change the magnitude | size of an audio | voice as needed.

  Here, when there are a plurality of CMs with a “playback” flag in the content like the content 250, the CM information 215 corresponding to the CM 252 closest to the playback position (main part 251) at the time of pause is selected. In this way, the relevance between the main story and the CM can be strengthened. In addition to this method, there is also a method of selecting at random from CMs with a “playback” flag.

  Next, the sub-screen generation unit 109 converts the CM252 pause screen received from the playback unit 108 as a sub-screen and sends the sub-screen to the screen composition unit 111. The screen synthesis unit 111 synthesizes the CM screen being played directly sent from the playback unit 108 and the paused screen of the viewing content sent from the child screen generation unit 109 and sends the synthesized screen to the video output unit 113. Then, the screen synthesized by the screen synthesis unit 111 is output to the display device via the video output unit 113 (step S409). Here, the viewer may be able to specify the ratio of the screen sizes generated by the screen composition unit 111 or the form of screen superimposition (for example, semi-transparent superposition).

  From the above, when the viewer gives a pause instruction during playback of a screen such as the playback screen 601 in FIG. 6, the screen that was being played back is paused as shown in the pause screen 602 in FIG. The CM video can be displayed on the right side of the screen while being displayed on the screen.

  Next, the procedure from the state in which the CM 252 is played back to the return to the playback of the main part 251 while the main part 251 in FIG. 2 is paused will be described with reference to the flowchart 500 in FIG. After starting the reproduction of the CM 252 in step S408, the control unit 150 confirms the temporary stop release input of the input unit 102 (step S501).

  When the pause release input is transmitted from the input unit 102 to the control unit 150 (step S501: Yes), the control unit 150 determines whether or not the CM 252 is being played back (step S503). For example, the control unit 150 instructs the playback unit 108 to stop playback of the CM 252 (step S504). If the CM 252 is not played back (step S503: No), the process proceeds to step S510, and the playback of the main part before the pause is resumed.

  On the other hand, if there is no pause cancellation input from the viewer in step S501 (step S501: No), the control unit 150 determines whether or not the CM 252 is being reproduced (step S502), and must be being reproduced. If the playback is in progress, the control unit 150 acquires the current playback position from the playback unit 108, and sets the playback position as the CM position and / or the CM end position 212 of the history information 210. By comparing, it is confirmed whether or not the CM reproduction is finished (step S505).

  In step S505, if the CM reproduction has not been completed yet, the process returns to step S501 and the input signal is confirmed again (step S505: No). In step S 505, when the CM 252 being played ends, the control unit 150 acquires the current time from the timer unit 106. Then, the previous reproduction date and time 213 of the CM 252 that has been reproduced is updated with the current time, and the reproduction flag 214 is changed to “not reproduced”. Then, the updated CM position and / or history information 210 is stored in the CM position and / or history information recording medium 105 as necessary (step S506).

  Next, the control unit 150 determines whether or not CM information with a “playback” flag exists on the CM position and / or history information 210 (step S507). In step S507, if the CM information 216 with the “play” flag is present on the CM position and / or history information 210, the control unit 150 sets the playback position of the playback unit 108 to the CM of the CM 253 to be played next. Move to start position 211. Then, the playback unit 108 starts playback of the CM 253 in response to an instruction from the control unit 150 (step S508), and returns to step S501.

  On the other hand, in step S507, when there is no CM with the “play” flag (step S507: No), the control unit 150 operates the child screen generation unit 109 to stop generation of the child screen and perform screen composition. The unit 111 stops the synthesis with the child screen (step S509).

  Next, the control unit 150 reads the playback position at the time of pause recorded on the temporary recording medium 151 in step S407, and moves the playback position of the playback unit 108 to the position of the main part 251 at the time of pause. Then, the control unit 150 operates the reproduction unit 108 to resume reproduction of the main part 251 that has been paused (step S510).

  Next, the outline of the operation at the time of suspension will be described with reference to FIGS. As shown in FIG. 7, among the three CMs included in one content 250, the first CM 252 (corresponding to the CM information 215) has been played back (with a “do not play” flag) and is currently the first one. When the main part 255 between the second CM 252 and the second CM 253 is being reproduced, when the pause input from the viewer is received (step S401), the reproduction of the main part 255 is paused (step S402).

  When a certain period of time has passed (steps S403 to 404), two CMs (CM information 216 to 217) corresponding to the CM information (CM information 216 to 217) in which the “playback” flag is set from the acquired CM position and / or history information 210 are displayed. CMs 253 to 254) are detected, and the CM 253, which is an unreproduced CM located closest to the current reproduction position, is reproduced (steps S405 to 409).

  When the reproduction of the CM 253 is completed (step S505: Yes), as shown in FIG. 8, the previous reproduction date / time 213 and the reproduction flag 214 of the CM information 216 corresponding to the CM 253 are updated (step S506). Since the CM 254 has not been reproduced yet, the CM 254 is subsequently reproduced (step S508).

  When a pause release operation is performed during the reproduction of the CM 254 (step S501: Yes, step S503: Yes, step S504), the screen composition is canceled and the reproduction of the original content is resumed (steps S509 to 510). At this time, as shown in FIG. 8, the CM position and / or the history information 210 are reproduced once because the CM 252 and CM 253 are reproduced, and the reproduction flag 214 of each CM information is updated to “not reproduced”.

  Since the suspension of the CM 254 is released during the CM reproduction, the previous reproduction date 213 of the corresponding CM information 217 remains unset, and the reproduction flag 214 also remains “reproduced”.

  Next, the operation when the viewer reproduces the content will be described with reference to the flowchart 900 of FIG.

  In normal playback, the content stored in the recording medium 104 is sent to the playback unit 108, and the playback unit 108 converts the sent information into a playback signal and outputs the video via the audio output unit 112 and the screen synthesis unit 111. By sending it to the unit 113, the viewer can view the video. As a premise here, when content reproduction is started, the control unit 150 obtains the CM position and / or history information 200 of the content to be reproduced from the CM position and / or history information recording medium 105 in advance and records it on the temporary recording medium 151. Keep it. Then, the reproduction of the content is started.

  During the content reproduction, the control unit 150 compares the current reproduction position acquired from the reproduction unit 108 with the CM position corresponding to the content acquired from the temporary recording medium 151 and / or the CM start position 201 in the history information 200. Then, it is confirmed whether or not the current reproduction position is immediately before the start of CM (step S901). If it is not immediately before the start of CM, the process returns to step S901 again to continue the confirmation.

  In step S901, when it is determined that it is immediately before the start of the CM, the control unit 150 acquires information regarding the CM immediately after the current playback position from the CM position and / or history information 200, and the CM playback flag 240 indicates “ It is determined whether or not “play” is set (step S902).

  As a result, when the “playback” flag is attached to the CM immediately after the current playback position, the playback unit 108 continues playback to the CM start position 201 (step S903). When the playback position enters the CM portion, the playback unit 108 plays back the CM following the main part (step S904). While continuing to play the CM, the control unit 150 acquires the current playback time from the playback unit 108 and compares it with the CM end position 202 in the CM information / history information 200 corresponding to the CM being played back (step S905). . If the CM has not yet reached the CM end position 202, the process returns to step S904, and the reproduction of the CM is continued.

  If it is determined in step S905 that the CM has reached the CM end position 202, the control unit 150 acquires the current time from the timer unit 106, and the CM position and / or history information 200 corresponding to the CM reproduced in step S904. The previous reproduction date 203 is updated with the current time (step S906). Then, the CM position and / or history information 200 is recorded on the temporary recording medium 151 as necessary.

  Then, the playback unit 108 continues playback of the main part following the CM (step S909).

  In step S902, when the control unit 150 determines that the “not reproduced” flag is attached to the CM, the reproducing unit 108 reproduces the main part to the CM start position 201 (step S907). When the current reproduction position reaches the CM start position 201, the control unit 150 moves the current reproduction position of the reproduction unit 108 to the CM end position 202 (step 908), and continues reproduction of the main part (step S909).

  For example, three CMs (CMs 252 to 254) are inserted in the main part like the content 250 in FIG. 8, and the “no reproduction” flag is set in the reproduction flag 214 of the CM information 215 and 216 corresponding to the CMs 252 and 253. In the case where the playback position has reached just before the start position of the CM 253 as shown in FIG. First, the control unit 150 checks the playback flag 214 in the CM position and / or history information 210 since the playback position has reached the CM start (45'05 ") (step S901: Yes, step S902).

  Since the reproduction flag 214 of the CM information 216 is “not reproduced”, the reproduction is continued up to the CM start position (45′05 ”), then the CM 253 is skipped and the reproduction of the main part 256 is continued (step S902: Yes). Steps S903 to 909) In this way, the reproducing unit 108 automatically skips the CM 253 and continues to reproduce the main part.

  As described above, the recording / playback apparatus 100 described in the present embodiment includes the CM detection unit 107 that detects the start position and the end position of the CM included in the video content, the CM start position, the end position, the previous playback date, and the playback flag. CM position and / or history information 200 composed of the control unit 150 that performs CM reproduction control with reference to the CM position and / or history information 200, and the CM position and / or history that stores the information 200 By providing the information recording medium 105 and the screen composition unit 111 that synthesizes the content paused screen and the CM playback screen, the control unit 150 can display the CM position when the viewer is viewing the content. In addition, referring to the history information 200, a CM once viewed can be automatically skipped. In addition, when the viewer instructs to pause the content reproduction, the CM position and / or history information 200 can be referred to reproduce a CM that has not yet been reproduced and is included in the content.

  As a result, even if the viewer skips the CM by an operation such as fast-forwarding, the CM is played back during the pause, so it is possible to secure an opportunity to play the CM intended by the content distributor, and the CM that has been played once Is skipped during playback of the main part, so that the main part can be played back while the viewer is devoted to watching the main part during content playback.

Although the present embodiment has been described for CM, the present embodiment can be applied to content such as data broadcast and text broadcast inserted in content such as digital broadcast as well as CM. The same applies to the following embodiments.
(Example 2)
In the second embodiment, when an operation menu screen is displayed during content reproduction and an operation is performed, the screen that has been reproduced is paused and included in the paused content together with the operation menu screen. The CM video is displayed with reference to the CM position and / or history information 200. The present embodiment can be implemented using the same recording / playback apparatus 100 as in the first embodiment.

  First, processing when the viewer displays an operation menu screen while viewing content will be described with reference to FIG. When the viewer instructs the menu screen display using an input device such as a remote controller while viewing the content, the input unit 102 notifies the control unit 150 that the menu screen display operation has been performed (step S1101). The control unit 150 causes the playback unit 108 to pause playback of the content (step S1102). At this time, the control unit 150 records the playback position paused on the content on the temporary recording medium 151 (step S1103).

  Next, the control unit 150 generates a menu screen by the control screen generation unit 110, and sends the generated menu screen to the screen composition unit 111 (step S1104). Then, the control unit 150 acquires the CM position and / or history information 200 from the CM position and / or history information recording medium 105 or the temporary recording medium 151 (step S1105).

  From the acquired CM position and / or history information 200, it is confirmed whether or not there is a CM with a “playback” flag (step S1106). In step S1106, if a CM with a “play” flag does not exist in the content, a child screen is not generated, and the control unit 150 sends a video signal of only the menu screen to the screen synthesis unit 111 to the display unit 112. An instruction to send is sent (step S1111).

  In step 1106, when there is a CM with a “play” flag, the control unit 150 instructs the playback unit 108 to move the playback position to the head of the CM with the “play” flag. Then, the control unit 150 causes the reproduction unit 108 to reproduce the CM, sends a video reproduction signal to the child screen generation unit 109, and sends a CM audio reproduction signal to the audio output unit 112 (step S1107).

  Then, the sub-screen generation unit 109 converts the video received from the playback unit 108 into a sub-screen and sends it to the screen composition unit 111. The screen composition unit 111 synthesizes the menu screen generated in step S1104 and the sub screen on which the CM is displayed (step S1108). FIG. 14 shows a screen example in which the menu screen and the CM playback screen are combined.

  The playback unit 108 continues the CM playback until the CM playback ends (steps S1109 and S1110). When the reproduction of the CM is completed, the control unit 150 acquires the current time from the timer unit 106, updates the CM position of the terminated CM and / or the previous reproduction date / time 203 in the history information 200, and the CM position as necessary. And / or it records on the history information recording medium 105 (step S1112).

  The control unit 150 checks whether or not there is a CM element with a “playback” flag in the CM position and / or history information 200 (step S1113).

  If there is a CM with a “playback” flag in step S1113, the process returns to step S1107 to continue playing the CM.

  If there is no CM with the “play” flag in step S1113, the control unit 150 instructs the playback unit 108 to stop the transmission of the video signal to the child screen generation unit 109, and at the same time, the child screen. The generation unit 109 is instructed to stop transmission of the video signal to the screen composition unit 111 (step S1114). As a result, the screen returns to the normal menu screen on which no CM is displayed.

  Next, during the menu screen operation, processing that uses the entire screen for function execution is also conceivable. In such a case, a procedure for performing the menu screen operation will be described with reference to FIG.

  A flowchart 1200 of FIG. 12 shows a processing procedure when the viewer performs various operations on the menu screen after the menu screen is displayed according to the procedure of the flowchart 1100. Each time the viewer operates the menu screen, the control unit 150 processes the menu screen operation signal sent from the input unit 102 (step S1201).

  The control unit 150 determines whether the menu operation instructed by the viewer is an operation that can secure a space for displaying the sub screen of the CM video on the screen (step S1202). The operations that prevent the CM from being displayed on the screen include, for example, image quality adjustment operations and setting operations that require many items to be displayed.

  If it is determined in step S1202 that the menu operation from the viewer is an operation that cannot display the CM on the screen (step S1202: No), the control unit 150 instructs the playback unit 108 to select the CM being played on the child screen. Pause. Then, the temporary stop position is recorded on the temporary recording medium 151 (step S1203).

  Next, the sub-screen composition is canceled (step S1204), and the control unit 105 performs necessary control according to the operation from the viewer (step S1208). In step S1202, when the input from the viewer is an operation capable of displaying a CM on the screen, the control unit 150 determines whether there is a paused CM (step S1205). When there is a paused CM, the control unit 150 instructs the playback unit 108 to resume playback of the CM (step S1206).

Next, the control unit 150 operates the sub-screen generation unit 109 to convert the CM video sent from the playback unit 108 into a sub-screen, and sends the sub-screen video to the screen composition unit 111. Then, the screen composition unit 111 synthesizes the menu screen sent from the control screen generation unit 110 and the CM sub-screen video sent from the sub-screen generation unit 109 and sends them to the video output unit 113. And the control part 105 performs required control according to operation from a viewer (step S1208).

  Here, after the operation of the menu screen is finished, there are a case where the content reproduction screen is displayed before the menu operation is started and a case where the content reproduction screen is not returned as a result of the menu screen operation. For example, the case of not returning to the content playback screen before the start of the menu operation is a case where the content to be played back is changed, such as channel change, photo browsing or website browsing. Return processing from the menu screen will be described with reference to the flowchart 1300 of FIG.

When the viewer performs an operation on the menu screen and then instructs to end the operation (step S1301), the control unit 150 determines whether or not the CM is being reproduced at that time (step S1302).
When the CM is being reproduced, the control unit 150 instructs the reproduction unit 108 to stop the reproduction of the CM and cancel the composition of the screen (steps S1303 and S1304).
Then, in step S1301, the control unit 150 determines whether or not to return to the content reproduction screen before the start of the menu operation after the last operation received from the input unit 102 is completed (step S1305).

  When returning to the content playback screen before the start of the menu operation after the operation is finished, the control unit 150 instructs the playback unit 108 to store the playback position in the temporary recording medium 151 stored in the temporary recording medium 151 in step S1103. The content is moved to the reproduction position and reproduction is resumed (step S1306).

  If it is determined in step S1304 that the content reproduction screen before the start of the menu operation does not return, the control unit 150 operates the reproduction unit 108 to change to a screen to be changed according to the operation (step S1307).

  From the above, in the recording / reproducing apparatus 100 described in the present embodiment, when the viewer instructs menu screen operation during content reproduction, the control unit 150 automatically pauses content reproduction and displays the menu screen. At the same time, an unreproduced CM included in the content is reproduced with reference to the CM position and / or history information 200.

Also, when displaying a menu screen that needs to use the entire screen of the display device, CM playback control is performed such that CM playback is continued or stopped according to the operation state of the menu screen. Accordingly, it is possible to prevent the viewer from overlooking the content when operating the menu screen, and to secure an opportunity to reproduce the CM without hindering the viewer's operation.
(Example 3)
In the first and second embodiments, the CM once played cannot be played back again, but in this embodiment, the CM position and / or the playback flag 204 in the history information 200 is used to repeat the paused pause. It is possible to reproduce a CM, or to reproduce a CM that has passed a certain period of time from the previous reproduction time.

  Such processing can be performed automatically, or can be performed in response to an operation on a menu screen such as a screen 1501 in FIG. Processing for automatically and repeatedly reproducing a CM while the currently viewed content is paused will be described with reference to a flowchart 1550 in FIG. In the first embodiment, the process for detecting the CM to be reproduced during the pause is step S406 in FIG. 4 and step S507 in FIG. When all the CMs to be played back have been played back during the pause, the control unit 150 determines in step S 406 and step S 507 that there is no CM with a “play back” flag, so the CM playback is performed. Instead, you will wait for the normal pause screen.

  Therefore, in order to reproduce the CM that has already been reproduced, in this embodiment, it is determined whether or not there is a CM with the “reproduce” flag in the CM position and / or history information 200 in step S1551. If the process corresponds to step S406 and step S507, and the control device 150 determines that there is no CM with the “playback” flag, step S1552 is performed.

  In step S1551, when the control unit 150 determines that the CM with the “playback” flag does not exist in the content, the control unit 150 displays the CM position and / or history information 200 associated with the paused content. Operate to change all the playback flags 204 to “play while main part is stopped” (step 1552). The “playback while main part is stopped” flag has the same meaning as the “playback” flag when paused or when a menu screen is operated, but has the same meaning as “do not play” during main part playback. That is, in step S902 in FIG. 9, the “playback while main part is stopped” flag is treated as “not played”.

  From the above, even when all the CMs included in the content are reproduced at the time of suspension, the CM position and / or the reproduction flag 204 of the history information 200 is updated to “reproduce”, so that the CMs can be reproduced repeatedly.

  The above method can also be applied during the menu screen operation of the second embodiment.

  In addition to the above, as a method of reproducing the CM again, a case where only a CM for which a certain time has passed since the last viewing of the content is reproduced again can be considered. A method for replaying a CM whose arbitrary date and time (for example, X days) has passed since the previous playback date and time will be described with reference to a flowchart 1600 in FIG.

  First, the control unit 150 acquires the CM position and / or history information 200 of the CM position and / or history information update target content from the CM position and / or history information recording medium 105 (step S1601). Then, the control unit 150 acquires from the previous reproduction date and time 203 and the timer unit 106 the CM for which the reproduction flag 204 is set to “not reproduced” from among the CMs included in the CM position and / or history information 200. The current time is compared (step S1602).

  If it is determined that the predetermined date / time (X days) has passed since the previous reproduction date / time 203, the control unit 150 changes the reproduction flag 204 of the CM to be updated to “reproduce” (step S1603). If it is determined that it is not too long, no change is made (step S1602: No).

  If there is CM information that has not yet been confirmed for update in the CM position and / or history information 200, the process returns to step S1602, and the control unit 150 continues to update the CM position and / or history information 200 (step S1604). : Yes). After confirming all CMs included in the content, the control unit 150 records the CM position and / or history information 200 in the CM position and / or history information recording medium 105 (step S1605).

  Here, the timing of executing the processing of the flowchart 1600 may be passively performed by remote control input from a viewer or automatically performed periodically, and either method may be used. The target content may be only specific content or a plurality of contents. When a plurality of contents are targeted, the processing can be realized by repeatedly performing the processing of the flowchart 1600.

From the above, in the recording / reproducing apparatus 100 described in the present embodiment, the control unit 150 refers to the setting value of the reproduction flag 204 in the CM position and / or history information 200 and changes the setting value as necessary. In addition, it is possible to repeatedly reproduce a specific CM or to display a CM that has been reproduced once after a certain period of time has elapsed, thereby enabling flexible CM reproduction control.
Example 4
Next, Example 4 will be described with reference to the drawings. In the third embodiment, the reproduction control of the CM included in the content is executed only by the recording / reproducing apparatus 100. However, in this embodiment, the CM reproduction performed in the third embodiment is performed between the video transmitting apparatus and the video receiving apparatus. A method for executing the control will be described.

  FIG. 17 is a diagram illustrating configurations of the video transmission device 1700 and the video reception device 1750. The video transmission device 1700 and the video reception device 1750 are network-connected by a communication medium such as an IP network such as the Internet, a wired or wireless LAN, a universal serial bus (USB), and a high-definition multimedia interface (HDMI). Shall. In addition, one video transmission apparatus 1700 can transmit video to a plurality of video reception apparatuses 1750 by simultaneously reproducing a plurality of videos by the playback unit 108.

  The video transmission apparatus 1700 includes a recording medium 104, a CM position and / or history information recording medium 105, a timer unit 106, a CM detection unit 107, a reproduction unit 108, a sub-screen generation unit 109, a control screen generation unit 110, and a screen synthesis unit 111.

The communication unit 1701 is a part that performs transmission / reception of video / audio signals and transmission / reception of control signals to / from other devices connected to the network, and performs transmission signal encryption and reception signal decryption as necessary. It has become. Other parts are the same as those of the recording / playback apparatus 100.

  The video receiving device 1750 includes an input unit 102, an audio output unit 112, a video output unit 113, a control unit 1770, and a communication unit 1751. The communication unit 1751 is a part that executes reception of video / audio signals and transmission / reception of control signals, and performs encryption of transmission signals and decryption of reception signals as necessary. The control unit 1770 performs overall control of each unit, and notifies an operation instruction from the viewer via the input unit 102 to the video transmission apparatus 1700 via the communication unit 1751 as necessary. Other parts are the same as those of the recording / playback apparatus 100.

  In order to show that the same effect as in the third embodiment is exhibited, an input / output process between the video transmission device 1700 and the video reception device 1750 will be described. On the video transmission device 1700 side, the CM position and / or history information 200 is created in advance for each content stored in the recording medium 104 using the procedure described in FIG. It is assumed that it is stored in the history information recording medium 105.

When the viewer performs a “play” operation on the input unit 102 of the video reception device 1750 using an input device such as a remote controller, the input unit 102 transmits the operation input signal input to the control unit 1770. Then, the control unit 1770 determines the type of the operation input signal, and in the case of “playback”, the “playback” operation request is sent to the video transmission device 1700 via the communication unit 1751 (if necessary) and its associated information (for example, , Name of content to be played, playback speed, etc.).
The communication unit 1701 of the video transmission apparatus 1700 receives the “play” operation request and notifies the control unit 150 of it.

  The control unit 150 determines the content of the operation request, and in the case of “playback”, instructs the playback unit 108 to play back the content recorded on the recording medium 104. In response to an instruction from the control unit 150, the screen composition unit 111 outputs a video signal of the playback content to the communication unit 1701. The audio of the playback content is sent from the playback unit 108 to the communication unit 1701. The communication unit 1701 converts video and audio signals into a format suitable for communication as necessary, and transmits the converted video and audio signals to the video receiving device 1750.

  The communication unit 1751 of the video reception device 1750 receives the video / audio signal transmitted from the communication unit 1701 and converts the video signal into a format suitable for the audio output unit 112 and the video output unit 113 in accordance with an instruction from the control unit 1770. The audio signal is sent to the audio output unit 112, and the video signal is sent to the video output unit 113.

  By performing the above procedure, content is reproduced between the video transmission device 1700 and the video reception device 1750 in the same manner as in the third embodiment.

  Next, a processing operation when the viewer performs a “pause” operation on the input unit 102 of the video reception device 1750 using an input device such as a remote controller will be described.

  The input unit 102 of the video reception device 1750 notifies the control unit 1770 of an operation input signal as in the case of performing the “play” operation. The control unit 1770 determines the type of the operation input signal, and in the case of “pause”, transmits a “pause” operation request to the video transmission device 1700 via the communication unit 1751. The communication unit 1701 of the video transmission device 1700 receives the “pause” operation request and notifies the control unit 150 of the request.

  The control unit 150 determines the content of the operation request, and in the case of “pause”, the playback unit 108 is instructed to pause content playback as illustrated in FIG. 4 of the first embodiment. Then, the CM position and / or history information 200 stored in the CM position and / or history information recording medium 105 is acquired, the CM information in which the “playback” flag is set is extracted, and the playback of the CM is performed by the playback unit 108. To instruct. The playback unit 108 starts playback of the CM, sends the CM video to the screen composition unit 111, and simultaneously sends the main screen that is temporarily stopped to the child screen generation unit 109.

  Next, the sub-screen generation unit 109 converts the CM pause screen received from the playback unit 108 as a sub-screen and sends it to the screen composition unit 111. The screen synthesis unit 111 synthesizes the CM screen being played directly sent from the playback unit 108 and the pause screen of the viewing content sent from the child screen generation unit 109, and outputs them to the communication unit 1701.

  The communication unit 1701 converts video and audio signals into a format suitable for communication as necessary, and transmits the converted video and audio signals to the video receiving device 1750. The communication unit 1751 of the video reception device 1750 receives the video / audio signal transmitted from the communication unit 1701 and converts the video signal into a format suitable for the audio output unit 112 and the video output unit 113 in accordance with an instruction from the control unit 1770. The audio signal is sent to the audio output unit 112, and the video signal is sent to the video output unit 113.

  By performing the above procedure, the CM screen can be displayed together with the content stop screen when the content being played back between the video transmission device 1700 and the video reception device 1750 is paused as in the first embodiment. It becomes.

  Also, using the same procedure as described above, the video transmission apparatus 1700 may execute CM reproduction control such as skipping already reproduced CMs described in the first to third embodiments or repeatedly reproducing CMs. it can.

  Unlike the video transmission device 1700, the video transmission device 1800 transmits only information necessary for the video reception device 1850 to generate a screen via the communication unit 1801. The control unit 150 of the video reception device 1850 outputs information received via the communication unit 1851 to the control screen generation unit 110 and instructs to generate a control screen such as a menu screen according to the information.

  Here, the video transmission apparatuses 1700 and 1800 shown in FIGS. 17 and 18 may be installed in the same place as the video reception apparatuses 1750 and 1850, or may be installed in another place as a content distribution center. A configuration in which a plurality of video receiving apparatuses 1750 and 1850 are connected is also conceivable.

  As described above, the video transmission devices 1700 and 1800 and the video reception devices 1750 and 1850 described in the fourth embodiment include both communication units 1701, 1751, 1801, and 1851 for transmitting and receiving contents and control signals. Content and control signals can be transmitted and received between the video transmission apparatuses 1700 and 1800. The video transmission apparatuses 1700 and 1800 perform CM detection of the content, create and manage the CM position and / or history information 200, and the video reception apparatuses 1750 and 1850. Content / CM playback / transfer control can be performed via the communication units 1701, 1751, 1801, and 1851.
