[Technical field to which the invention belongs]
The present invention relates to a technique for automatically creating a digest of video and audio.
【0002】
[Conventional technology]
Conventionally, when creating a video digest, the digest creator selects a video scene set in advance by the video editor or a scene extracted by a method such as automatically detecting a break in the video by a computer. It was artificially created by cutting and joining. As a method of automatically creating, there is a method of extracting only a characteristic part such as a sound intensity or a video change, or a method of extracting an appropriate time from the video regardless of the content of the video.
【0003】
[Patent Document 1]
Japanese Unexamined Patent Publication No. 11-331761 [0004]
[Problems to be Solved by the Invention]
When creating a digest artificially, it is very difficult to create it so that it will be well received by the viewer. Therefore, it is conceivable to have the viewer evaluate it once and reflect the result. However, it takes a lot of time to create a digest video from a plurality of programs.
【0005】
Also, if you create it automatically, you can save the trouble and time of creating it, but it does not necessarily include the part that looks attractive to the viewer side in the digest, and it is actually from the viewer. I don't know if I can get a good evaluation. Digests are used, for example, in advertisements, but the above-mentioned conventional techniques have not been able to produce effective advertisements using digests.
【0006】
In addition, although the parts that can be seen effectively in the video differ depending on the viewer's generation, area of residence, gender, etc. (user profile), these differences could not be reflected in the digest.
【0007】
An object of the present invention is to provide a method and an apparatus for automatically creating an effective digest using an audience rating and a viewing frequency.
【0008】
[Means for solving problems]
In order to achieve the above object, the present invention can be configured as follows.
【0009】
The present invention is a method in which a digest creation device creates a digest of video or audio, and includes an acquisition step of acquiring an hourly audience rating or viewing frequency of video or audio to be digested, and the audience rating or the above-mentioned audience rating or It has an extraction step of extracting video or audio in a time interval in which the audience rating exceeds a predetermined threshold, and a generation step of generating a digest using the extracted video or audio.
【0010】
According to the present invention, since the digest is generated based on the audience rating or the viewing frequency, it is possible to create an effective digest that matches the interests of the viewer.
【0011】
The above acquisition step can be configured to include a step of acquiring viewing data indicating that the viewer has viewed the video or audio, and a step of aggregating the viewing data to obtain the audience rating or the viewing frequency. .. Further, the audience rating or the viewing frequency may be acquired from an external device.
【0012】
Further, instead of the extraction step and the generation step, when the video or audio to be created in the digest is composed of a plurality of programs, the audience rating or the viewing frequency exceeds a predetermined threshold value from the plurality of programs. It is also possible to configure the program to have a step of acquiring a short story of the program created in advance and a step of creating a digest using the short story.
【0013】
According to the present invention, it is possible to extract a climax scene of a program having a high audience rating or a high viewing frequency, and it can be used as an advertisement for stored video contents such as a program or video on demand.
【0014】
Further, in the above method, there is a step of designating a video or audio of a specific genre as the video or audio to be created for the digest, and a step of creating a digest of the video or audio belonging to the designated genre. You may. According to the present invention, for example, it is possible to automatically create a digest of only a video related to "baseball".
【0015】
Further, in the above method, the audience rating or the viewing frequency corresponding to the viewer group having a specific user profile may be acquired, and the digest may be created using the audience rating or the viewing frequency.
【0016】
The above user profiles include region, gender, age group, and the like. According to the present invention, by using the user profile, it is possible to create a digest according to the target for delivering the digest video as an advertisement, and it is possible to create a more effective digest.
【0017】
Further, in the above method, the audience rating or the viewing frequency of the predetermined time portion is increased or decreased by a predetermined amount, and the increase or decrease thereof is made according to the content of the video or audio to be created by the digest. Digests may be generated using the reduced ratings or ratings.
【0018】
According to the present invention, it is possible to preferentially include a part to be included in the digest and not to include the other part in the digest according to the content of the image, and it is possible to create a more effective digest. It will be possible. Further, in the above method, the predetermined time portion and the predetermined amount may be changed according to the time.
【0019】
Further, in the above method, a predetermined video or audio portion according to the content of the video or audio to be created by the digest is excluded from the target range of the digest, or the predetermined video or audio The portion may be included in the digest.
【0020】
By excluding the predetermined part from the target range of the digest, the part where the impression when seeing the main part is diminished if it is shown in advance as a video before the main part is distributed or at the initial stage of distribution. By not including it in the digest, it is possible to prevent the digest delivery from being counterproductive as an advertisement.
【0021】
In addition, by including the predetermined part in the target range of the digest, the intention of the sponsor or the actor's office, such as the scene in which the actor who wants to be shown in the digest is reflected or the scene incorporated for the digest, etc. This makes it possible to effectively capture the scenes that you want to actively incorporate into the digest. The predetermined video or audio part may be changed according to the time.
【0022】
By making it possible to change the limit range, it is possible to incorporate more interesting scenes and scenes that can be expected to have advertising effects as a new digest creation range over time, and people who were not interested in the initial digest It becomes possible to deliver more effective advertisements to. In addition, by making it possible to change the range to be preferentially incorporated, it is possible to reconfigure the digest so that the initial digest, which was composed only of the sponsor's intention, becomes closer to the actual viewing entity over time. It is possible to efficiently change the video digest, such as by capturing the video that could not be captured by the digest of the times over time.
【0023】
Further, in the above method, the difference between the audience rating or the viewing frequency obtained in the first period and the audience rating or the viewing frequency obtained in the second period is obtained, and the digest is created according to the difference. A specific part of the target video or audio may be added to or deleted from the digest.
【0024】
According to the present invention, it is possible to create a digest in consideration of the viewer's interests that change with the passage of time.
【0025】
Further, in the above method, the difference between the audience rating or the viewing frequency of the viewer who has viewed the digest and the audience rating or the viewing frequency of the viewer who has not viewed the digest is obtained, and the digest is obtained according to the difference. It is also possible to add or remove a specific part of the video or audio to be created from the digest.
【0026】
According to the present invention, even though the digest is created based on the viewing location, when the viewing points and the like shift over time, the audience rating and the viewing frequency based on the viewing status of the new viewer who saw the digest can be obtained. By using it, it is possible to create a new effective digest by reflecting the deviation from the initial viewing point.
【0027】
Further, according to the present invention, a digest creating device suitable for carrying out the above method is provided. Further, a program for causing the computer to execute the processing of the above method and a recording medium for recording the program are provided, and the computer can execute each step of the above method.
【0028】
As described above, according to the present invention, it is possible to create a digest specialized for an advertisement distribution target by using a user profile such as a viewer's region, age, and gender. On the other hand, depending on the intention of the sponsor of the video data, it is possible to flexibly respond to those intentions by reflecting the parts that you do not want to be included as a digest or the parts that you want to be actively included in the digest using a filter. It will be possible.
【0029】
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described. In the following description of the embodiment, a "video" is taken as an example, and the "video" may be only a video, but generally includes audio. Further, even in the case of only audio without including video, it is possible to create a digest in the same manner as in the case of "video".
【0030】
In the system according to the embodiment of the present invention, the audience rating or the viewing frequency of the program being broadcast or the program played from the recording medium for each hour is totaled via the network, and the image of the portion higher than the set threshold value is displayed. By extracting, the degree of interest of the viewer in the video is determined. Based on this determination result, a video portion having a high audience rating is automatically extracted to create a digest video. The term audience rating in the present specification may also include the concept of the number of viewers.
【0031】
1A and 1B are diagrams for explaining the concept of the embodiment of the present invention. (A) is an example of a graph showing the relationship between the time and the audience rating on XX days. In the present invention, a threshold value is set in advance for the audience rating, and a video of a time when the audience rating exceeds the threshold value is picked up to create a digest video. In the case of (A), the first time the audience rating exceeded the threshold was picked up in the video of the variety program (a), and the second time was in the video of the news program (b). Hereinafter, each time the audience rating exceeds the threshold value, the video at that time is picked up.
【0032】
The picked-up video with a high audience rating is edited as a digest video. (B) is an example of the digest video on XX days. The digest video of the example of (B) is created based on the audience rating of (A). In this example, a digest video is created from the video (a), the video (b), and the following video when the audience rating exceeds the threshold in the order of time when the audience rating exceeds the threshold in (A).
【0033】
The audience rating indicates the degree of interest of the viewer, and it can be said that the video with a high audience rating is also the part of the same program that the viewer is also interested in. In addition, a program having a higher audience rating than other programs indicates that the program is of high interest, and the climax scene or promotional video of the program is considered to be more interesting to the viewer.
【0034】
As described above, the present invention can create a digest video that is more interesting to the viewer by automatically detecting the video portion having a high audience rating and extracting the video portion. In the graph shown in FIG. 1 (A), the vertical axis uses the audience rating, but when the vertical axis uses the number of viewers (referred to as the number of viewers in the present specification), it is hourly. It becomes a histogram showing the audience rating.
【0035】
Hereinafter, each embodiment of the present invention will be described with reference to the drawings.
【0036】
(First Embodiment) In the first embodiment, a method of creating a digest video in real time from a program being broadcast will be described, but the same applies to the case of creating a digest video from a program played back from a recording medium. Can be carried out.

The threshold value setting unit 11 sets a threshold value determined by the digest video creator based on past audience rating statistics and analogy from the total number of terminals. The threshold is set for each time zone (period), for example, {19:00, 20:00, ...}, {morning, noon, night, midnight}, a week, a month, etc. be able to. The target program designation unit 12 acquires information on the target program from the digest target program list 51 designated by the digest video creator.
【0043】
Here, FIG. 4 is a diagram showing an example of the digest target program list 51 in the first embodiment. The digest target program indicates one or a plurality of programs to be digested, and can be arbitrarily specified by the digest video creator. The time zone and channel may be specified as in the example of FIG. 4, or one broadcasting station may be specified and only the time zone may be specified. In addition, by designating only programs of a specific genre, it is possible to create a digest video for each genre by preparing a digest target program list including only programs of a specific genre. It is also possible to specify one genre from a plurality of genres, and to create a digest containing only programs of the specified genre.
【0044】
The digest target program list may be stored in the digest video creation device, or data may be acquired from the outside at any time via the network.
【0045】
The viewing data acquisition unit 13 acquires viewing data from a plurality of viewer terminals 2. The audience rating calculation unit 14 calculates the audience rating from the plurality of viewing data acquired by the viewing data acquisition unit 13.
【0046】
Here, the audience rating at time t is calculated by the audience rating (t) = the number of viewing terminals (t) ÷ the total number of terminals (t). The number of viewing terminals is the number of terminals that are viewing the target program at the same time t in the received viewing data. The total number of terminals is the total number of terminals subject to the audience rating aggregation, for example, the number of members of the target service.
【0047】
The extraction determination unit 15 compares the audience rating calculated by the audience rating calculation unit 14 with the threshold value set by the threshold value setting unit 11. The digest video extraction unit 16 acquires the program content 50 from the broadcasting station 3 in real time, extracts the video at a time when the audience rating is higher than the threshold value as the digest video based on the comparison result of the extraction judgment unit 15, and the audience rating. A digest video is created by truncating the low-time video.
【0048】
FIG. 5 is a diagram illustrating the extraction of the digest video in the first embodiment. FIG. 5 (A) shows an example of the audience rating of each digest target program every 30 seconds. Here, the program ID is information that identifies each digest target program. For example, when the threshold value is set to 20%, the audience rating portion surrounded by the double line in FIG. 5 (A) is extracted. FIG. 5 (B) shows a video portion extracted as a digest from the audience rating of FIG. 5 (A).
【0049】
Further, when creating a digest video from a broadcasted program, a means for temporarily storing the program content 50 may be provided so that the digest video extraction unit 16 can acquire the program content from the means. Further, when creating a digest video from a broadcasted program, for example, a video storage device is connected to each viewer terminal instead of the broadcasting station 3 in FIG. 2, and the program is played from there. Further, in this case, instead of the viewing time of the viewing data, the relative time from the start time of a certain program is used, and the audience rating is used instead of the viewing frequency in the third embodiment described later. Can be created.
【0050】
FIG. 6 is a digest video creation flowchart according to the first embodiment. First, a threshold value specified by the digest video creator for each time zone, for example, is set based on past audience rating statistics or analogy from the total number of terminals (step S10). Next, the processes after step S12 are repeated (step S11) until the digest target program specified in the digest target program list ends, and when the process ends, the process proceeds to step S18.
【0051】
In step S12, the audience rating is calculated based on the viewing data collected from the viewer terminal 2. Next, the calculated audience rating is compared with the set threshold (step S13), and if the audience rating is higher than the threshold, it is confirmed whether the video of the program currently being broadcast is being extracted as a digest video (step S13). In step S14), if the extraction has not started yet, the video currently being broadcast is started as a digest video (step S15), and the process returns to step S11. If the extraction is already in progress, the extraction is continued as it is (step S16), and the process returns to step S11.
【0052】
In the determination of step S13, if the audience rating is lower than the threshold value, the extraction is stopped if the digest video is being extracted, and if the extraction is not started yet, the extraction stopped state is continued as it is (step S17), and the process returns to step S11. ..
【0053】
When the end of the digest target program is confirmed in the determination in step S11, it is confirmed whether the current video is being extracted as the digest video (step S18), and if it is being extracted, the extraction is finished (step S19). , Ends the process of creating the digest video.
【0054】
In this way, it is possible to create a digest video by extracting only the portion of the video whose audience rating is higher than the threshold value. The digest video may be a single video collected in the order of extraction, or may be an individual video.
【0055】
Further, in the first embodiment, the digest video creation device 1 receives viewing data from a plurality of viewer terminals 2, and calculates the audience rating by itself from the received viewing data, but directly from the viewer terminal 2.

For the acquired digest target program, the calculated maximum audience rating is compared with the set threshold value (step S24), and if the audience rating is higher than the threshold value, a short video composed mainly of the original video of the program. Extract 54 as a digest video (step S25), and return to step S22. If the maximum audience rating is lower than the threshold value in step S24, the program returns to step S22 as it is without creating a digest video.
【0069】
In the second embodiment, the maximum audience rating is calculated for each program and compared with the threshold value, but it does not have to be the maximum audience rating as long as the digest video can be extracted in comparison with the threshold value, for example. , In order to measure the audience rating of each program as a whole, the average audience rating from the start to the end of the program is calculated for each program, and it can be used for comparison with the threshold for extracting the digest video. Good.
【0070】
In this way, it is possible to create a digest video that is a collection of short videos organized mainly on the original video such as a climax scene of a program having a high audience rating or a promotional video.
【0071】
Further, in the second embodiment, the digest video creation device 6 receives viewing data from a plurality of viewer terminals 2 and calculates the audience rating by itself from the received viewing data, but the external device for calculating the audience rating is calculated. The calculated audience rating may be obtained from the device of.
【0072】
(Third Embodiment) In the first and second embodiments, the audience rating is used as an index for extracting the video to be used as the digest, but the audience rating can also be used instead of the audience rating. Hereinafter, embodiments in the case of using the viewing frequency will be described. In the following description, when the number of viewers (= the number of viewing data extraction devices corresponding to the video viewing device in which the video to be created as a digest is reproduced, or the number of viewers for each viewing data extraction device can be grasped. Is the number including the number of viewers) is called the viewing frequency. Further, in the third embodiment, the video (including the broadcast program) reproduced by the video viewing device 90 is targeted for digest creation.
【0073】
FIG. 11 is a system configuration diagram showing the present embodiment. As shown in the figure, this system includes a viewing data extraction device 100 that acquires and transmits viewing data of a video transmitted from the video viewing device 90, and viewing data transmitted from a plurality of viewing data extraction devices 100.

The viewing data extraction unit 101 receives information on jumps and searches used for video search during viewing from the video viewing device 90, and information on jumped parts and actually reproduced parts related to their processing. And the content ID that identifies the video data currently being viewed (hereinafter, this information is referred to as viewing data) is extracted.
【0075】
FIG. 12 shows a configuration example of viewing data. Of (a) to (b), the information of (a) indicating "reproduction" is reflected in the histogram described later, and the jump and search information is not reflected in the histogram.
【0076】
The video viewing device 90 is a device that reproduces video, such as a DVD player, a video deck, and an STB for VOD that receives and reproduces video from a broadcast or network. That is, the "video" in the present embodiment includes a video distributed by broadcasting, a video distributed via a network, a video by package media, and the like.
【0077】
The viewing data transmission unit 102 transmits the extracted viewing data to the digest video creation device 110 via the communication network 105.
【0078】
The digest video creation device 110 stores the viewing data receiving unit 111 that receives the viewing data sent from the plurality of viewing data extraction devices 100 via the communication network 105, and the viewing data for each viewing data extraction device or viewer. It has a viewing data storage unit 112, a video data storage unit 113 in which the same video as the video being viewed by the video viewing device 90 is stored, and a digest video creation unit 114.
【0079】
The digest video creation unit 114 uses the viewing data of the video data for which the digest video is created from the viewing data stored in the viewing data storage unit 112, and in the reproduction of the content, a plurality of viewings are performed at a certain unit time. The viewing frequency of how many viewing data extraction devices 100 the content was viewed in the data extraction device 100 is made into a histogram, a part of the video having a high viewing frequency is extracted from the histogram, and that part is used as the video data storage unit 113. Take it out from and splice it together to edit it as a digest.
【0080】
In the present embodiment, the video viewing device 90 and the viewing data extraction device 100 are separate devices, but the viewing data extraction device 100 may be incorporated in the video viewing device 90. The configuration in which the viewing data extraction device 100 is incorporated in the video viewing device 90 corresponds to the viewer terminal in the first and second embodiments.
【0081】
Further, the viewing information receiving unit 111 and the viewing data storage unit in the digest video creating device 110 may be in a device different from the digest video creating device 110, and in this case, the digest video creating device 110 can be viewed at any time from the device. Acquire and use data. Further, the video data storage unit 113 can also be placed in an external device.
【0082】
FIG. 13 is an operation flow of this system in the third embodiment. First, the viewing data extraction device 100 extracts viewing data from the video viewing device 90 (step 101). In the present embodiment, the viewing data is extracted in real time at the same time as the video viewing, but the viewing data may be collectively received from the video viewing device 90 after the video viewing.
【0083】
Then, the viewing data transmission unit 102 in the viewing data extraction device 100 transmits the extracted viewing data to the digest video creation device 110 via the communication network 105 (step 102). The communication network 105 may be any communication network, whether wired or wireless, as long as it can transmit viewing data.
【0084】
Subsequently, the digest video creation device 110 receives the viewing data from the plurality of viewing data extraction devices 100 via the communication network 105 (step 103). The received viewing data is stored in the viewing data storage unit 112 for each content (for example, a broadcast program, a movie, etc.) (step 104). FIG. 14 shows an example of viewing data stored in the viewing data storage unit 112. The example shown in FIG. 14 is an example in which "reproduction" of the viewing data is sequentially accumulated for each content ID.
【0085】
Then, when creating the digest video, a histogram is created by accumulating the parts actually viewed by the viewer using the accumulated viewing data (step 105).
【0086】
The procedure for creating the histogram is described in detail below with reference to FIG. Based on this histogram, the video data of the content to be digested, which is stored in the video data storage unit 113 centering on the part actually viewed by the viewer, is taken out and stitched together to create a digest video. (Step 106).
【0087】
FIG. 15 is a flowchart showing a procedure at the time of creating a histogram in the third embodiment of the present invention. In the following processing, the processes of steps 111 to 115 are performed for each viewing data to create a histogram.
【0088】
First, for the first viewing data, the viewing discrimination section is set to the first 5 seconds of the video data (step 111). Setting 5 seconds is an example, and the discrimination section may have any length. In this determination section, 1 is added to the histogram of the section to indicate that the section has been viewed, and nothing is performed if the section is not viewed (steps 112 to 113).
【0089】
Then, it is determined whether or not the viewing determination section is at the end of the video data (step 114). If not the last, set the next 5 seconds as the viewing discrimination section (step 115). After determining whether or not to view the entire video data of the target content, the histogram data of the viewing section is added in the same manner for the next viewing data. The process is repeated in the same manner for all viewing data (steps 116 to 117).
【0090】
FIG. 16 is a diagram for explaining a procedure for creating a digest in the third embodiment.
【0091】
To create a digest, first, a section in the histogram whose viewing degree is higher than a certain threshold value is selected (step 121), and the video corresponding to that section is extracted from the video data storage unit 113 (step 122). Then, the extracted images are joined together to create a digest image (step 123). The threshold value is set in advance based on past viewing frequency statistics, the total number of viewers, and the like. This threshold value may be an absolute number (for example, a portion viewed by 100 or more people is extracted), or may be a number considering the total number of viewers. When considering the total number of viewers, it is equivalent to setting a threshold value based on the audience rating.
【0092】
It is also possible to obtain a digest based on the audience rating similar to the first and second embodiments by obtaining a graph of the audience rating from the histogram by using the total number of viewers.
【0093】
Further, in the present embodiment, the digest video creation device creates a histogram based on the viewing data, but the created histogram may be acquired from the outside to create a digest.
【0094】
As described above, since the portion viewed by a larger number of viewers can be edited as a digest, it is possible to generate an effective digest that reflects the interests of the viewers. In the third embodiment as well, similarly to the second embodiment, a digest video is created using a short video of a program whose maximum viewing frequency exceeds a predetermined threshold value in a plurality of programs. Is also possible.
【0095】
As described above, according to the first to third embodiments of the present invention, by extracting the video having a high audience rating of the actually broadcast program, or in the reproduced video. By extracting the video viewed by many viewers, it is possible to automatically create a digest video that collects only the scenes that are of interest to the viewer. In addition, if a short video composed mainly of the original video such as the climax scene of a program with a high audience rating or high viewing frequency or a promotional video is extracted as a digest video, the stored video content such as a program or video on demand can be advertised. It can also be used as.
【0096】
(Fourth Embodiment) In the fourth embodiment, a digest is created using the viewer's viewing data corresponding to a specific user profile based on the viewer's user profile such as the viewer's gender and age. It is a thing.
【0097】
That is, in the system of the first and second embodiments, the audience rating is obtained using the audience rating of the viewer corresponding to the specific user profile, and the video is extracted based on the audience rating to create a digest. Further, in the system of the third embodiment, the viewing frequency is obtained using the viewing data of the viewer corresponding to the specific user profile, and the video is extracted based on the viewing frequency to create a digest.
【0098】
Hereinafter, the fourth embodiment will be specifically described based on the configuration of the third embodiment as an example.
【0099】
FIG. 17 is a system configuration diagram showing a fourth embodiment of the present invention. In the following description, the same components as those in the third embodiment are designated by the same reference numerals, and the description thereof will be omitted.
【0100】
In the system of the fourth embodiment, not only the viewing data but also the video viewing device 90 is placed for each video content and each viewing data extraction device instead of the viewing data storage unit 112 in the system of the third embodiment. The viewing data storage unit 122 is used to store the user profile of the viewer such as the area where the video is being viewed and the gender and age of the viewer using the video viewing device 90. When creating a viewing histogram, the digest video creation unit 114 creates a histogram that limits the target range of the viewer using user profiles such as a specific region, a specific age group, and a specific gender, and based on that. Create a digest video. FIG. 18 shows an example of a user profile stored in the viewing data storage unit 122.
【0101】
That is, for example, it is possible to create a digest video of a viewer who lives in a specific area. Also, for example, it is possible to create a digest video for people in their 20s.
【0102】
FIG. 19 is an operation flow of the system according to the fourth embodiment of the present invention. The operation of the system in the fourth embodiment will be described with reference to the figure.
【0103】
After the digest video creation device 110 receives the viewing data (similar to steps 101 to 103), when the viewing data is accumulated, the user profile such as the region, age, and gender in which the viewer exists is simultaneously accumulated (step). 201). Then, the digest video creation unit 114 creates a histogram using only the viewing data in a specific range such as a specific region, a specific age group, and a specific gender based on the viewer information when creating the viewing location histogram (step). 202). Then, a digest video that reflects a specific range of tastes is created. The method of creating the digest itself is the same as that of the third embodiment (step 106).
【0104】
The user profile used to limit the audience may be a combination of a plurality of conditions, such as a combination of age and region. In addition to region, age, and gender, any parameter that can limit the viewer to a certain range may be used.
【0105】
Further, the user profile may be received from the viewing data extraction device at the time of receiving the viewing data and stored, or may be stored in advance in the storage device at the time of user registration or the like. As a method of receiving from the viewing data extraction device at the time of receiving the viewing data, there is a method in which the viewer inputs a user profile to the viewing data extraction device using an IC card or the like, and the viewing data extraction device transmits the input data. In addition, the ID of the viewing data extraction device and the corresponding user profile are stored in advance in the digest video creation device or a device that can be accessed by the digest video creation device, and when the viewing data extraction device transmits the viewing data, the ID of the viewing data extraction device is also stored. There is also a way to send it.
【0106】
(Fifth Embodiment) In the fifth embodiment, a digest restriction filter that specifies a part of the video that should not be included in the digest is used, and the portion specified by the digest restriction filter is included in the digest. It is a form to prevent it. The digest restriction filter can be applied to any system of the first to third embodiments, but here, an example applied to the system of the third embodiment will be described.
【0107】
FIG. 20 is a system configuration diagram showing a fifth embodiment of the present invention. The system of the fifth embodiment has, in addition to the system of the third embodiment or the fourth embodiment, a digest filter storage unit 135 that stores a digest restriction filter indicating a portion of the image that should not be included in the digest. .. This filter is provided for each content as needed. This filter consists of, for example, one or more video sections (eg, start time-end time) that indicate parts that are not included in the digest.
【0108】
FIG. 21 is a diagram for explaining a procedure for creating a digest according to the fifth embodiment of the present invention.
【0109】
After selecting the target range to be reflected in the digest (step 121), the part that should not be included in the digest from the digest target range generated from the histogram using the digest limit filter stored in the digest filter storage unit 135 (digest limit target). Remove the range) (step 222) and make it a new digest target range (step 123).
【0110】
In this way, by using the digest restriction filter, the digest includes the part where the impression when seeing the main part is diminished if it is shown in advance as a video before the main part is distributed or at the initial stage of distribution. By making sure that there is no such thing, it is possible to prevent the digest delivery from being counterproductive as an advertisement.
【0111】
It is also possible to replace the digest restriction filter with each other at a specified period after distribution of the video data to use a different digest restriction filter. By doing this, for example, the restriction filter can be relaxed step by step to increase the target scenes of the digest, and create a digest that incorporates more effective scenes for viewers who were not interested in the first digest. Is possible.
【0112】
(Sixth Embodiment) In the sixth embodiment, a digest priority filter indicating a part to be preferentially included in the digest is used, and the part of the video specified by the digest priority filter is preferentially included in the digest. It is something that can be done. The digest priority filter can also be applied to any system of the first to third embodiments, but here, an example applied to the system of the third embodiment will be described.
【0113】
The system of the sixth embodiment has, in addition to the system of the third embodiment or the fourth embodiment, a digest filter storage unit 135 that stores a digest priority filter indicating a portion to be preferentially included in the digest. That is, the system of the sixth embodiment is a system in which the digest priority filter is stored in the digest filter storage unit 135 instead of the digest restriction filter in the system configuration diagram shown in FIG.
【0114】
FIG. 22 is a diagram for explaining a procedure for creating a digest according to the sixth embodiment of the present invention.
【0115】
After selecting the first target range to be reflected in the digest (step 121), a new histogram is created by adding the addition frequency of the priority part on the histogram using the digest priority filter stored in the digest filter storage (step 121). Step 324), select a new digest target range using it, and create a digest (step 123). When applied to the system of the first embodiment, the audience rating may be increased.
【0116】
According to the present invention, by appropriately setting the priority filter, the scene in which the actor to be shown in the digest is reflected or the scene incorporated for the digest is positively selected according to the intention of the sponsor or the actor's office. It is possible to effectively capture the scene that you want to capture.
【0117】
It is also possible to replace the digest priority filter at each specified period after the distribution of the video data to use a different digest priority filter. According to this, for example, the digest can be reconfigured so that the initial digest, which was composed only of the sponsor's intention, is closer to the actual viewing entity, and the video that could not be captured by one digest is incorporated over time. It is possible to efficiently change the digest image, such as by going on.
【0118】
(Variation example of the fifth and sixth embodiments) The digest priority filter in the sixth embodiment is the same as the digest restriction filter in the fifth embodiment, and the portion specified by the filter is It is also possible to configure it so that it is always included in the digest. On the contrary, the digest restriction filter may be configured to reduce the viewing frequency of the portion specified by the digest restriction filter, as in the digest priority filter in the sixth embodiment.
【0119】
Also, without distinguishing between the digest restriction filter and the digest priority filter, the viewing frequency is added or subtracted for one or more parts of the video from the beginning to the end of a certain content according to the content of the video. It is also possible to use a filter that does. In this case, the unit of addition or subtraction is not always 1. For example, the value to be added can be set to a large value for the portion that is to be included in the digest with particular priority, and the value to be subtracted can be set to a large value for the portion that is not particularly to be included in the digest.
【0120】
(7th Embodiment) The 7th embodiment creates a digest in consideration of whether or not the viewer has previously viewed the digest. The processing method in the present embodiment can be applied to any system of the first to third embodiments, but here, an example based on the system of the third embodiment will be described.
【0121】
FIG. 23 is a system configuration diagram showing a seventh embodiment of the present invention. In the system of the seventh embodiment, instead of the viewing data storage unit 122 in the system of the fourth embodiment shown in FIG. 17, not only the viewing data and the user profile for each video content but also the viewer previously The viewing data storage unit 142, which also stores information on whether or not the digest is being viewed, is used.
【0122】
The digest video creation unit 114 creates a histogram targeting only the viewers who see the digest and a histogram targeting only the viewers who do not see the digest, obtains the difference, and obtains the difference, for example, under normal conditions. Recreate the digest by adding it to the original digest you created.
【0123】
FIG. 24 is an operation flow of this system according to the seventh embodiment of the present invention.
【0124】
After receiving the viewing data from a plurality of viewing data extraction devices (steps 101 to 103), when the viewing data is stored in the viewing data storage unit 142, information on whether or not the viewer has previously viewed the digest is simultaneously stored. (Step 301). When creating a new viewing histogram, the digest video creation unit 114 creates a histogram of only the viewers who are watching the digest and a histogram of only the viewers who are not watching the digest, and obtains the difference between them (step 302). After that, the addition / deletion part in the original digest is determined from the difference, and a new digest is created. (Step 303).
【0125】
As an example, whether or not a viewer is viewing the digest can use information on whether or not the viewing data is received after the digest is distributed and whether or not the viewer is in the digest distribution target area. .. If the viewer meets these conditions, it is possible that the viewer has already viewed the digest.
【0126】
Next, the procedure for creating the digest will be further described with reference to FIG.
【0127】
Compare the histogram of the viewer who saw the digest video with the histogram of the viewer who did not see the digest, and subtract the value of the histogram of the viewer who did not see the digest from the histogram value of the viewer who saw the digest video. Then, the difference is obtained (viewing frequency difference in the figure, step 411).
【0128】
Then, the part where the difference is positively large is used as the additional part, the part where the difference is negatively large is used as the deleted part (step 412), and the original digest is re-edited to create a new digest (step 413). That is, of the parts where the difference is truly large, the part included in the video range of the original digest is left as it is, and the part not included in the original video range is newly added as a digest. Also, of the parts where the difference is large negatively, the part not included in the video range of the original digest is left as it is, and the part included in the original video range is deleted. It should be noted that, for example, a threshold value can be used to determine how large the difference is when adding or deleting.
【0129】
As described above, by utilizing the information indicating whether or not the digest has been viewed, if the viewing points shift over time, a new histogram will be created based on the viewing status of the new viewer who saw the digest. It is possible to create a new effective digest by reflecting the deviation from the initial viewing part based on it.
【0130】
It is also possible to correct the digest by using the difference between the histogram created at a certain time and the histogram created at another time, instead of the difference using the information that the digest is seen or not seen. This makes it possible to create a digest that takes into account the passage of time.
【0131】
In addition, in order to apply this embodiment to the first embodiment, the difference in audience rating may be obtained and the same processing may be performed.
【0132】
A part or all the functions of each processing unit in the digest video creating apparatus of each embodiment of the present invention are configured by a computer program, and the program is executed by using, for example, the computer shown in FIG. The form can be realized. The computer shown in FIG. 26 has a CPU 201, a memory 202, a hard disk 203, an input device 204, an output device 205, a CD-ROM drive 206, and a communication processing device 207.
【0133】
In addition, the above program can be recorded and saved on a computer-readable recording medium such as an FD (floppy (registered trademark) disk), MO, ROM, memory card, CD-ROM, DVD, or removable disk. , Can be distributed. The program can also be provided over networks such as the Internet and e-mail.
【0134】
As described above, according to the fourth to seventh embodiments of the present invention, it is possible to create a digest video that reflects the user profile, so that it is possible to create a digest focusing on a specific user profile. For example, by identifying an area, which is one of the user profiles, a digest that more effectively reflects the part rooted in that area, such as an image of a sports team closely related to the area or an image of a store that is popular in the area. Can be created.
【0135】
Furthermore, by specifying the age group and gender, it is possible to create and distribute a digest specialized for the target audience when selling the content. In addition, it is possible to flexibly respond to requests from video content distribution companies and production companies, as well as videos that the actors want to include in the digest and videos that they do not want to include. In addition, the restriction filter can be relaxed step by step to increase the number of scenes to be digested, and it is possible to create a digest that incorporates more effective scenes for viewers who were not interested in the first digest.
【0136】
Further, after the digest is transmitted once, it is possible to create the digest in consideration of whether or not the digest is viewed.
【0137】
The present invention is not limited to the above examples, and various modifications and applications can be made within the scope of the claims.
【0138】
[Effect of the invention]
According to the present invention, since the digest is generated based on the audience rating or the viewing frequency, it is possible to create an effective digest that matches the interests of the viewer.
