Description

The present invention relates to a video content management system, and more particularly to a video content management system that records video content and generates metadata.

At present, the broadcasting of a particular broadcasting station allows reception of three channels for digital broadcasting. This is called "multi-organization". "Multi-organization" is as follows.
In digital television broadcasting (terrestrial digital broadcasting, BS broadcasting) in Japan, a frequency domain for a plurality of channels is secured in one physical channel with standard image quality. Thus, standard definition broadcasts allow up to three different programs to be organized at the same time.

For example, when a sports broadcast is being broadcast on the main channel, the broadcasting time of the news program on the main channel is fixed, but the live broadcast of the sports may not end by that time. In such a case, the viewer is notified by a telop or an announcer that "This live broadcast can be viewed on a subchannel" is displayed on the screen of the broadcast program. In this case, the viewer is instructed to switch to the sub-channel by pressing the channel button on the controller, and can switch to the sub-channel and continue watching the sports broadcast. When the broadcast of the sports broadcast on the sub-channel is completed, the user is prompted to watch the main channel.

By the way, the applicant of the present application has constructed a system that records all broadcast programs, automatically creates metadata thereof, and facilitates searching and analysis of broadcast programs (for example, Patent Documents 1 and 2). Therefore, it is necessary to comprehensively record all broadcast programs and create metadata. This recording is basically performed based on the broadcast program guide.

However, the shift to the sub-channel as described above is not listed in the broadcast program table because it occurs due to chance circumstances such as "relay time is prolonged". Therefore, we would like to automatically record sub-channel broadcasts, but the current "all broadcast recording metadata automatic creation system" cannot handle this.

Store in a searchable manner.

The main channel recording unit 16 continues to record the video content of the main channel even when the determination unit 13 determines that the transition opportunity has occurred.
Therefore, in the video content management system 10 according to the present embodiment, it is possible to prevent the recording of the main channel from being stopped even while the sub-channel is being recorded.

The sub-channel recording unit 14 finishes recording the video content of the sub-channel when the video content is no longer provided by the sub-channel.
Therefore, in the video content management system 10 according to the present embodiment, recording can be automatically ended when the sub-channel ends.

The video content management system 10 according to this embodiment includes a character information recognition unit 18 that recognizes character information included in video content. When the character information recognition unit 18 recognizes character information suggesting a transition to a sub-channel (for example, character information such as "Continue on a sub-channel"), the determination unit 13 determines that a shift opportunity has occurred.
Therefore, in the video content management system 10 according to the present embodiment, it is possible to determine the transition timing based on the character information.

The video content management system 10 according to this embodiment includes a voice recognition unit 19 that recognizes voice included in video content. When the voice recognition unit 19 recognizes a voice suggesting a shift to a sub-channel (for example, a voice such as "Continue on a sub-channel"), the determination unit 13 determines that a shift opportunity has occurred.
Therefore, in the video content management system 10 according to the present embodiment, it is possible to determine the timing of transition from voice.

A video content management system 10 according to the present embodiment includes a scene change recognition unit 20 that recognizes a change in scene included in video content. When the scene change recognizing unit 20 recognizes a scene change suggesting a transition to a sub-channel (for example, a change from a baseball screen to a news screen), the determination unit 13 determines that a shift opportunity has occurred.
Therefore, in the video content management system 10 according to the present embodiment, it is possible to determine the transition timing based on the scene change.

The video content management system 10 according to this embodiment includes a communication data recognition unit 21 that recognizes communication data included in video content. The determination unit 13 detects communication data that the communication data recognition unit 21 suggests to shift to a sub-channel (for example, data that suggests a shift to a sub-channel included in MPEG2-TS, such as an electronic program guide [EPG], teletext data, data broadcast information, etc.), it is determined that a transition opportunity has occurred. Therefore, in the video content management system 10 according to the present embodiment, it is possible to determine the transition timing from the communication data.

Next, the overall configuration of the video content management system 10 according to the present embodiment will be described in detail along with its operation.
〔composition〕
The video content management system 10 according to the present embodiment automatically creates metadata based on recording information of all broadcast programs, and automatically detects the transition from the main channel to the sub-channel during broadcasting of a certain program. It is a system that recognizes and automatically records broadcast program information on sub-channels and automatically creates metadata for that broadcast program.
The video content management system 10 has the following two main configurations.

(1) Grasping the transition timing from the main channel to the sub-channel, recording the sub-channel, and creating metadata.
i: The timing of transition is grasped by character recognition of "telop" (such as "Please watch on the sub-channel after this") in the video. This determination is made by the character information recognition unit 18 .
ii: The shift trigger is recognized by the announcer's voice saying "Please watch on the sub-channel from now on". This determination is made by the speech recognition unit 19 .
iii: The shift trigger is recognized by a "scene change" (switching from a live sports video to a cover video of a news video). This determination is made by the scene change recognition unit 20 .
iv: The shift trigger also refers to communication data related to program broadcasting, such as "MPEG2-TS" data.
"MPEG2-TS" is a transmission format standard used for transmitting information such as terrestrial digital broadcasting, BS digital broadcasting, and CS digital broadcasting. Since the information of this standard includes electronic program guide (EPG) data, teletext data, and data broadcasting information, sub-channel schedules (at what point the main channel changes to the sub-channel If there is information on whether or not there is a possibility of switching to This determination is made by the communication data recognition unit 21 .
In this way, by referring to sub-channel transition information other than the video information of the program, it is possible to improve the accuracy of determining the timing of transition from the main channel to the sub-channel.
v: In addition, regarding the grasping of the transition information from the main channel to the sub-channel, the electronic program guide (EPG) included in the communication data related to the program broadcast by the communication data recognition unit 21, the teletext data, the data broadcast In addition to referring to information, etc., transfer to text media, such as TV information magazines, newspapers, magazines, etc., such as "If the program does not end in time, please watch it on a sub-channel." Information may be posted.
When such character medium information is converted into electronic information and exists on each website on the Internet, the communication data recognition unit 21 also searches for such transition information from the main channel to the sub-channel and recognizes the information. By referring to it, recording control is performed by shifting from the main channel to the sub-channel.
In this way, it is possible to further improve the accuracy of judging the timing of the transition from the main channel to the sub-channel by referring to the information on the transition to the sub-channel existing on the Internet other than the broadcast communication data of the program broadcast. becomes.
vi: When a program such as "extraordinary news" is changed in the event of a disaster or the like, a telop suggesting "extraordinary news" appears on the television screen. In addition, since the announcer utters the voice "extraordinary news", the announcer recognizes that it is "extraordinary news" through voice recognition. These determinations are made by the character information recognition unit 18 and the voice recognition unit 19 .
In the video content management system according to the present embodiment, with such a configuration, even if a shift to a sub-channel occurs during recording on the main channel, the sub-channel is automatically recorded. Metadata can be created by acquiring video radio waves corresponding to the frequency band of , and recording sub-channels.

(2) Aspects of how to record/create metadata i: All broadcast programs on both the main channel and sub-channels are recorded, and metadata on all broadcast programs is created. For example, in the case of "extraordinary news", the extra news is broadcast on the main channel, and the broadcast program that was being broadcast on the main channel is broadcast on the sub-channel. In this case, both the main channel and the sub-channel are recorded to create metadata.
ii: When the target program (for example, a live sports program broadcast on the main channel) does not end by the time of the news program determined in the program frame, and is automatically broadcast on the sub-channel. , the recording of the sports commentary program can be shifted from the main channel to the sub-channel, and the recording can be completed when the sports commentary program ends.

Next, the processing flow of the video content management system 10 will be described. The processing described in the flowchart of FIG. 2 is executed in the control main loop processing by the control unit 30 that controls each unit of the video content management system 10 .

The video content management system 10 follows instructions from the control unit 30, receives broadcast waves from a broadcasting station in the case of television broadcasting, or receives Internet broadcasting or the like with the receiving unit 11, and when performing video recording processing, A process of recording the main channel is executed (step S1). The recording of the main channel is executed by the control section transmitting a recording instruction to the main channel recording section 16 . Main channel recording can be performed when video content is provided on the main channel.

The video content management system 10 first executes processing for generating main channel metadata (step S2). The generation of main channel metadata is executed by the control section sending a generation instruction to the main channel metadata generation section 17 .
The video content management system 10 executes processing for confirming whether or not an opportunity to shift to a sub-channel has occurred (step S3). The decision unit 13 uses any one or all of the functions of the character information recognition unit 18, the voice recognition unit 19, the scene change recognition unit 20, and the communication data recognition unit 21 to determine whether or not the opportunity to shift to the sub-channel has occurred. Determined by If any one of the character information recognition unit 18, the voice recognition unit 19, the scene change recognition unit 20, and the communication data recognition unit 21 determines that the shift to the sub-channel has occurred, the determination unit 13 It can be determined that an opportunity to shift to a subchannel has occurred.

As a result, when it is confirmed that a shift to a sub-channel has occurred (Yes), the video content management system 10 executes step S4 "sub-channel recording" and step S5 "sub-channel metadata creation". On the other hand, if it cannot be confirmed that a shift to a sub-channel has occurred (No), the video content management system 10 executes step S6 without executing steps S4 and S5.

The video content management system 10 executes processing for recording the sub-channel (step S4). Sub-channel recording is executed by the control unit sending a recording instruction to the sub-channel recording unit 14 .

Next, the video content management system 10 executes processing for generating sub-channel metadata (step S5). Generation of sub-channel metadata is executed by the control unit transmitting a metadata generation instruction to the sub-channel metadata generation unit 15 .
The video content management system 10 executes processing for confirming whether or not a sub-channel end trigger has occurred (step S6). Whether or not a subchannel termination trigger has occurred is determined by the fact that the transmission of a program or content from a television station or Internet distribution source has stopped, or by the determination unit 13 using the character information recognition unit 18, the voice recognition unit 19, the scene The determination is made by using the functions of the change recognition section 20 and the communication data recognition section 21 . When any one of the character information recognition unit 18, the voice recognition unit 19, the scene change recognition unit 20, and the communication data recognition unit 21 determines that the sub-channel end opportunity has occurred, the sub-channel end opportunity is generated. can be determined to have occurred.

The sub-channel end trigger may be determined to have occurred when video content is no longer provided by the sub-channel, and occurred after a certain period of time (for example, several hours) from the start of sub-channel recording. can be determined.
As a result, when it is confirmed that a sub-channel termination trigger has occurred (Yes), the video content management system 10 executes step S7. On the other hand, if it cannot be confirmed that the sub-channel termination trigger has occurred (No), the video content management system 10 returns to step 4 without executing step S7, and performs "sub-channel recording" (S4). "Sub-channel metadata generation" (S5) is executed, and in step S6 "if it is detected that a sub-channel end trigger has occurred (S6), sub-channel recording is stopped in step S7.

The sub-channel recording is stopped by the control unit 30 sending a recording stop instruction to the sub-channel recording unit 14 . It should be noted that generation of metadata for the sub-channel is also terminated by stopping the recording of the sub-channel.
After completing the above processing, the video content management system 10 returns to the calling source and continues the processing. It should be noted that if the processing is to be continued, the processing in FIG. 2 will be executed again because the processing returns to the main loop processing.

Next, in the video content management system 10 according to the present embodiment, a display example of video content provided in the main channel and sub-channels in chronological order will be described with reference to FIG.
[Time 19:00]
At time 19:00, it is assumed that broadcasting of a baseball game has started on the main channel (step S10). It should be noted that, at this time point, no broadcasting is being performed on the sub-channel. However, the sub-channel may carry the same broadcast as the main channel.
In this case, the main channel recording unit 16 records the video content of the baseball broadcast, and the main channel metadata generation unit 17 generates metadata corresponding to the video content of the baseball broadcast.

[Time 20:59]
Originally, the baseball broadcast was scheduled to end at time 20:59, but here the baseball game has been prolonged (step S11).
In this case, a ``telop (continue on the sub-channel)'' is displayed in the video of the main channel, and the announcer utters a voice saying ``Please watch on the sub-channel after this''. The determination unit 13 determines that provision of the video content on the subchannel is started by a telop or sound.

[Time 21:00]
Broadcasting of the news program is started on the main channel as scheduled (step S12), and the continuation of the baseball relay is being broadcast on the sub-channel (step S13).
In this case, the main channel recording unit 16 records the video content of the news program, and the main channel metadata generation unit 17 generates metadata corresponding to the video content of the news program.
Also, the sub-channel recording unit 14 starts recording the video content of the baseball broadcast, and the sub-channel metadata generation unit 15 generates metadata corresponding to the video content of the baseball broadcast.

[Time 21:29]
The news program continues to be broadcast on the main channel (step S14), and the baseball broadcast has ended on the sub-channel (step S15). In this case, the character information "end" is displayed in the video of the subchannel, and the announcer utters a voice saying "the baseball broadcast is over". The judgment unit 13 judges that provision of the video content on the sub-channel ends due to the telop or sound. In this case, recording by the sub-channel recording unit 14 and generation of metadata by the sub-channel metadata generation unit 15 are finished.

[Time 21:30]
A news program is continuously broadcast on the main channel (step S16). On the other hand, sub-channels are not broadcast.
In this case, the main channel recording unit 16 records the video content of the news program, and the main channel metadata generation unit 17 generates metadata corresponding to the video content of the news program.

As described above, in the video content management system 10 according to the present embodiment, it is possible to automatically record the video content provided by the sub-channel, which can lead to the creation of metadata. Therefore, as a result, even when sub-channels are used, it is possible to comprehensively record video contents of broadcast programs and create metadata without omission. In addition, as for sub-channels, since recording is started after a shift trigger occurs, the memory capacity to be used can be reduced as compared with the method in which sub-channels are recorded from the beginning.

In addition, in the video content management system 10 according to the present embodiment, it is possible to record not only the sub-channels but also the video content provided by the main channel, which can lead to creation of metadata. Therefore, as a result, it is possible to comprehensively record video contents and create metadata in the main channel and sub-channels.

Furthermore, in the video content management system 10 according to the present embodiment, it is possible to prevent the recording of the main channel from being stopped even while the sub-channel is being recorded. All video content can be covered.

Furthermore, in the video content management system 10 according to the present embodiment, recording can be automatically terminated when the sub-channel ends. Recording can be excluded.
Moreover, in the video content management system 10 according to the present embodiment, it is possible to determine the transition timing based on the character information, so that the accuracy of determination of the transition timing can be improved.

In addition, in the video content management system 10 according to the present embodiment, since it is possible to determine the shift trigger by voice, it is possible to improve the accuracy of determination of the shift trigger.
Furthermore, in the video content management system 10 according to the present embodiment, it is possible to determine the timing of transition based on the change in scene, so that the accuracy of determination of the timing of transition can be improved.

Furthermore, in the video content management system 10 according to the present embodiment, it is possible to determine the transition timing based on the communication data, so that it is possible to improve the accuracy of determination of the transition timing.

In addition, by making manual settings in advance by the user in a commonly used TV recorder, it is possible to automatically switch from the main channel to the sub channel and record a program without missing it. There are conventional techniques, but in this conventional technique, the user must predict the possibility of transition to subchannels in advance and manually set the transition to the recorder each time. It was a complicated setting operation each time.

However, in the video content management system 10 according to the present embodiment, manual setting operations are not required each time, and a program on the main channel did not end within the scheduled time and was transferred to the sub-channel. In such a case, sub-channel recording is automatically performed, so that seamless program recording is automatically performed on the sub-channel without requiring manual operation each time. As a result, even if there is a shift to a sub-channel, recording is automatically and reliably performed and metadata is created.

In addition, since the purpose of the conventional technology is only to record the program, when the main channel is switched to the sub-channel, only the program which is switched to the sub-channel is recorded. However, in the video content management system 10 according to the present embodiment, even after the shift to the sub-channel, recording of subsequent programs on the main channel is performed in parallel. Since recording is performed, it is possible to achieve the purpose of creating comprehensive metadata by recording all programs.

The following modifications are possible in the embodiment described above.
(1) When the determining unit 13 determines that a plurality of recognizing units among the character information recognizing unit 18, the voice recognizing unit 19, the scene change recognizing unit 20, and the communication data recognizing unit 21 have generated an opportunity to shift to a sub-channel. It may be determined that an opportunity to shift to a sub-channel has occurred at this time. By configuring in this way, the accuracy of transition detection can be improved.
(2) The determination unit 13 may determine that an opportunity to shift to a sub-channel has occurred when provision of video content by a sub-channel has started, and furthermore, in the main channel broadcast video screen, a TV When an image of sub-channel operation with a remote controller appears, the image information may be image-recognized and determined as a shift trigger, and the present invention is not limited to the above-described embodiment.
(3) In the above embodiment, the case of recording a TV broadcast program from a TV broadcasting station and creating metadata has been mainly described. It can also be applied to receive video information from a distribution source and create metadata.

Since the present invention relates to a video content management system, it has wide industrial applicability.
