Description

  The present invention relates to a preference scene acquisition device and a preference scene acquisition system for acquiring a preference scene from a program broadcast by a program broadcasting system.

  In a mobile terminal device such as a mobile phone, when a TV program is viewed, it is difficult to view for a long time because the power supply capacity of the battery is limited. Also, when watching a TV program on a mobile terminal device, it is likely that the user will often watch for a short time rather than watching for a long time. Considering such a situation, a technique for viewing a certain part of a program rather than viewing the entire program is required in the mobile terminal device.

  Currently, there is a broadcasting system having a program reservation mechanism such as EPG, but if this is used, the entire program can be reserved, but one scene of the program cannot be reserved. In the conventional digital television, a broadcast schedule of a program can be defined in a local event information table (LIT) of program arrangement information, and only a part of the program can be reserved.

  In the above-mentioned digital television, in the case of a program that is recorded or edited and broadcast in advance, the schedule is fixed, and since it is not changed, even if the broadcasting schedule is accurately defined, Only a specific scene can be viewed or recorded.

Further, as a conventional technique, there is a preference scene acquisition system that adds metadata to video information and transmits the video information (see Patent Document 1).

  Next, the operation of the sending apparatus will be described in detail with reference to FIG. 2 together with FIG. FIG. 2 is a flowchart for explaining the operation of the sending device of the preference scene acquisition system according to the embodiment of the present invention.

  As shown in FIG. 2, in step ST201, the program information sending unit 112 sends program information including the start time of the scene. Next, subtitle creating section 113 determines whether or not it is the start of scene transmission (or scene switching) (step ST202).

  In step ST202, when the transmission of a scene is started (or scene switching), in step ST203, the subtitle creating unit 113 creates the subtitle by adding the content included in the program information to the subtitle (step ST204). 205).

  In step ST202, when it is not the start of scene transmission (or scene switching), the caption creation unit 113 creates and transmits captions corresponding to the broadcast contents (steps ST204 and 205).

  Next, the operation of the preference scene acquisition apparatus 120 will be described in detail with reference to FIG. 3 together with FIG. FIG. 3 is a flowchart for explaining the operation of the preference scene acquisition device 120 of the preference scene acquisition system 100 according to one embodiment of the present invention.

  As shown in FIG. 3, in step ST301, the preference scene acquisition apparatus 120 acquires program information. Next, in step ST302, the user selects a scene. Next, the preference scene acquisition apparatus 120 registers reservation information based on the scene selection (step ST303) and displays the reservation time (step ST304).

  Next, in step ST305, the preference scene acquisition apparatus 120 determines whether it is a reserved time. When it is the reserved time in step ST305, the preference scene acquisition apparatus 120 notifies the user, receives the scene information, and records (step ST306).

  When it is not the reserved time in step ST305, the preference scene acquisition apparatus 120 acquires subtitles (step ST307), determines the progress status, that is, determines whether broadcasting is performed as scheduled from the received subtitles and program information. (Step ST308).

  When the broadcast is being performed as scheduled in step ST308, that is, when there is no broadcast delay, the process returns to step ST305. When the broadcast is not performed as scheduled in step ST308, that is, when a broadcast delay occurs, the preference scene acquisition device 120 considers the delay time and sets the scheduled broadcast time in the reservation information management table 128. It corrects and updates the display (steps ST309 and 310), and returns to step ST305.

  In one embodiment of the present invention, as means for acquiring program information, means using program arrangement information such as LIT, means using data broadcasting in BML, and communication contents in HTML are used. There is a means or a means for calculating independently.

  Further, in one embodiment of the present invention, as the progress status judging means, a keyword is set for each scene and a judgment is made based on whether the keyword has appeared, a keyword appearance order for each scene, and the like. There is a means for defining a grammar to be shown and making a judgment against the grammar, or a means for making a judgment by performing natural language processing.

  These keywords and grammar information may be broadcast simultaneously with program information, acquired via the Internet, or customized by a user using a communication terminal device. In addition, when advanced processing such as natural language processing is required, information processing may be distributed in cooperation with a server.

Example 1
Next, Example 1 of the preference scene acquisition system 100 which concerns on one embodiment of this invention is demonstrated with reference to FIG. 4 with FIG. FIG. 4 is a flowchart for explaining the operation of Example 1 of the preference scene acquisition system 100 according to one embodiment of the present invention.

  In the first embodiment, the present invention is applied to a program that is broadcast as scheduled. When the keywords match, the video is recorded or viewed. Here, it is assumed that recording or viewing is performed if the scene of the program is determined by subtitles and the scene that the user wants to see is determined without considering the change in the progress of the program.

  First, as shown in FIG. 4, in step ST401, the user operates the scene selection unit 125 to register a keyword for determining a scene to be viewed. Next, the preference scene acquisition apparatus 120 receives subtitles (step ST402), and the progress determination unit 127 determines whether the scene is a scene that the user wants to see based on the registered information (step ST403).

  When it is a scene that the user wants to see in step ST403, the preference scene acquisition apparatus 120 performs recording or viewing for a predetermined time (step ST404). When it is not the scene that the user wants to see in step ST403, the preference scene acquisition apparatus 120 determines whether it is timed out (step ST405), that is, when the information registered for a predetermined time does not appear in the subtitles, the desired scene It is determined that the recording and viewing are finished (step ST406).

(Example 2)
Next, Example 2 of the preference scene acquisition system 100 according to an embodiment of the present invention will be described with reference to FIGS. 5, 6, and 7 together with FIG.

  FIG. 5 is a diagram for explaining the operation of Example 2 of the preference scene acquisition system 100 according to an embodiment of the present invention. FIG. 6 is another diagram for explaining the operation of Example 2 of the preference scene acquisition system 100 according to one embodiment of the present invention. FIG. 7 is a timing chart for explaining the operation of Example 2 of the preference scene acquisition system 100 according to one embodiment of the present invention.

  In the second embodiment, the present invention is applied to a news program. News programs are broadcast almost as scheduled, but the broadcast schedule may be changed due to emergency information or the like.

  News programs are often live broadcasts. The program structure is determined in minutes before the broadcast starts. The news program is composed of news corners by genre such as politics, economy, and sports, featured corners that feature the program, weather forecasts and fortune telling.

  Assume that a certain one hour news program has a schedule as shown in FIG. In this case, the operation will be described by taking an example where the user wants to see only sports news.

  First, before the program starts, the user selects the news program by program reservation using EPG or the like. Furthermore, in order to acquire a detailed schedule of the program, the preference scene acquisition apparatus 120 displays the LIT on the user using a browser or the like, and asks the user to select a desired corner. Here, it is assumed that the user selects “sports news”.

  At this time, the reservation management unit 129 registers the scheduled broadcast time and broadcast time in the reservation information management table 128 and displays the scheduled broadcast time on the program information display unit 124.

  The preference scene acquisition device 120 receives the subtitle and confirms whether the program has started as scheduled at 7 o'clock when the program starts. If there is no problem, the preference scene acquisition apparatus 120 acquires subtitles at intervals of 5 minutes and checks whether there is a change. The preference scene acquisition apparatus 120 repeats such processing, and corrects the reservation management information table 128 if the program content is changed.

  As an example, a case will be described in which emergency news is entered as shown in FIG.

  As shown in FIG. 7, when the preference scene acquisition device 120 receives subtitles at 7:20, it is understood that the scheduled “special feature” is not broadcast and “emergency news” is broadcast. , Continue to receive subtitles, and continue to receive until it is understood that the “special feature” is being broadcast at 7:25. At this point, the preference scene acquisition device 120 knows that a corner that is originally scheduled to be broadcast at 7:20 was broadcast at 7:25, which is 5 minutes behind.

  Therefore, the reservation management unit 129 delays the start time of the reservation information by 5 minutes and updates the display of the scheduled broadcast time. Then, at 7:45, the preference scene acquisition device 120 receives the broadcast and starts viewing or starts recording. Moreover, the preference scene acquisition apparatus 120 may notify the user by an alarm or the like several minutes before the start time.

  As described above, even when an unscheduled broadcast interrupts on the way, it is possible to accurately know the corner time desired by the user.

(Example 3)
Next, Example 3 of the preference scene acquisition system 100 according to an embodiment of the present invention will be described with reference to FIGS. 8 and 9 together with FIG.

  FIG. 8 is a diagram for explaining the operation of Example 3 of the preference scene acquisition system 100 according to the embodiment of the present invention. FIG. 9 is a timing chart for explaining the operation of Example 3 of the preference scene acquisition system 100 according to one embodiment of the present invention. FIG. 10 is another diagram for explaining the operation of Example 3 of the preference scene acquisition system 100 according to one embodiment of the present invention.

  In this third embodiment, the present invention is applied to a grand sumo relay. The sumo wrestling broadcast is scheduled, but depending on the approach, it may be early or late, so it is difficult to know the exact time if you only want to see the efforts of your favorite wrestlers. Therefore, the preference scene acquisition apparatus 120 calculates the approach time as follows.

  First, the preference scene acquisition device 120 acquires a schedule of efforts using data broadcasting or the like before the program starts. The time required for each approach is the average approach time. The preference scene acquisition device 120 displays the acquired approach information so that it can be selected by the user, and the user selects the approach that the user wants to see. Here, it is assumed that the user selects “Takanohana vs Chiyo no Fuji”. The selected approach is registered in the reservation management information table 128.

  Next, as illustrated in FIG. 9, the preference scene acquisition apparatus 120 receives subtitles at 5:10, which is the scheduled end time of the first approach. The preference scene acquisition device 120 seems to have not yet completed the first approach, and thus continues to receive subtitles until the next action is started. If the first action is completed at 5:12, the preference scene acquisition device 120 is delayed by 2 minutes from the schedule, so the reservation information is delayed by 2 minutes and corrected to 5:52.

  Next, the preference scene acquisition apparatus 120 receives the subtitle at 5:22 because the next approach starts with a delay of 2 minutes. At this time, if the preference scene acquisition device 120 finds that the approach has already been completed and the next approach has been started, it continues to receive the subtitles until the end of the approach. In this case, the preference scene acquisition device 120 has ended its efforts at 5:25. The preference scene acquisition device 120 is 7 minutes earlier because it was supposed to end at 5:32 in the revised schedule. Therefore, the preference scene acquisition device 120 corrects the reservation information to 5:45 ahead of 7 minutes.

  Next, when the preference scene acquisition apparatus 120 receives the subtitle at 5:35, since the approach has not been completed, the preference scene acquisition apparatus 120 continues to the end. The preference scene acquisition device 120 delays the reservation information by 7 minutes and sets the time to 5:52 since the end of the approach at 5:42. The actual sumo broadcast time and the contents of the efforts are as shown in FIG.

  The preference scene acquisition apparatus 120 receives the subtitle and starts viewing or recording from the time when the end of the approach since the next approach is the approach immediately before the desired approach. Note that the preference scene acquisition apparatus 120 may notify the user that the desired action is started several minutes before the desired action is shown.

Example 4
Next, Example 4 of the preference scene acquisition system according to the embodiment of the present invention will be described with reference to FIGS. 11 and 12 together with FIG.

  FIG. 11 is a diagram for explaining the operation of Example 4 of the preference scene acquisition system 100 according to an embodiment of the present invention. FIG. 12 is another diagram for explaining the operation of Example 4 of the preference scene acquisition system 100 according to one embodiment of the present invention.

  In Example 4, the present invention is applied to a professional baseball broadcast. In a sports program such as a baseball game, the progress of the program is not decided at all, and the progress is difficult to predict. In such a case, the preference scene acquisition device 120 receives and monitors the subtitles at fine intervals or continuously in order to obtain a more accurate one. Here, a description will be given taking a professional baseball broadcast as an example.

  In the case of baseball broadcasts, there may be demands such as viewing only one of the attack scenes, viewing only a certain player's at-bat, or viewing only at a chance. Here, an operation in the case where the user looks only at a bat of a certain player will be described.

  First, the preference scene acquisition apparatus 120 acquires the batting order information of each team using data broadcasting. For baseball broadcasts and the like, there is no schedule information because the progress of the program has not been decided. Therefore, an average time is determined based on past data, and schedule information is created.

  For example, in the case of professional baseball, the average game time of one game is considered to be about 3 hours. If this is equally divided into 9 innings, it is 20 minutes per inning, and the time for one team to attack is considered to be 10 minutes. On the other hand, since the average number of bats for one batter in one game is four, the number of batters for one inning is considered to be four.

  Therefore, the time for one batter is considered to be 2 minutes 30 seconds. From the above, when the batting order information as shown in FIG. 11 is obtained, the program schedule as shown in FIG. 12 can be configured. The preference scene acquisition device 120 can predict the time at which a batter is to bat by performing monitoring as described in the third embodiment based on this schedule.

  The present invention has an effect of accurately acquiring a viewing scene desired by a user, and is useful for a preference scene acquisition device and a preference scene acquisition system.
