Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a technique for automatically creating a video and audio digest.
[0002]
[Prior art]
Conventionally, when creating a video digest, the digest creator creates a video scene preset by a video editor or a scene extracted by a method of automatically detecting a video break by a computer. It was created artificially by cutting and joining. As a method of automatically creating, there are a method of extracting only a characteristic part such as the strength of sound and a change of video, or a method of extracting an appropriate time from the video regardless of the content of the video.

[0004]
[Problems to be solved by the invention]
When creating a digest artificially, it is very difficult to create a digest so that the viewer can appreciate it. Thus, a method is conceivable in which the viewer is evaluated once and the result is reflected. However, when a digest video is created from a plurality of programs, it takes a very long time.
[0005]
In addition, if it is created automatically, it can save time and effort of creation, but it does not necessarily include the part that looks attractive to the viewer side in the digest, it is actually from the viewer I don't know if a good evaluation can be obtained. For example, the digest is used for advertisement, but the above-described conventional technology cannot make an effective advertisement using the digest.
[0006]
In addition, although the portions that can be seen effectively in the video differ depending on the viewer's generation, the area in which they live, gender, etc. (user profile), these differences could not be reflected in the digest.
[0007]
It is an object of the present invention to provide a method and apparatus for automatically creating an effective digest using the audience rating and audience rating.
[0008]
[Means for Solving the Problems]
In order to achieve the above object, the present invention can be configured as follows.
[0009]
  In the present invention, a digest creation device creates a video or audio digest.Create digestA method,
  Video or audio for which a digest is to be createdThe viewer's viewing data is received, and the viewing data and information on whether or not the viewer is watching the previous digest of the video or audio are stored in the storage means of the digest creation device.Steps,Based on the viewing data and information stored in the storage means, the viewing rate or viewing frequency of the video or audio for which the viewer who viewed the previous digest is to create the digest for each time, and the previous digest Find the difference between the audience rating or audience rating for each hour of the video or audio that is the subject of the digest creation of viewers who are not viewingSteps,A specific part of the video or audio for which the difference is in a time interval in which the difference value exceeds a predetermined threshold is added to the previous digest, and the digest in the time interval in which the difference value is less than a predetermined threshold Delete a specific part of video or audio to be created from the previous digestSteps.
[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 suitable for the viewer's interest.In addition, according to the present invention, when the viewing point or the like shifts with time even though the digest is created based on the viewing location, the viewing rate or viewing based on the viewing status of the new viewer who has seen the digest. It is possible to create a new effective digest by reflecting the deviation from the initial viewing location using the frequency.
[0014]
The above method may further include a step of designating a video or audio of a specific genre as the video or audio for which the digest is created, and a step of creating a video or audio digest belonging to the designated genre. May be. According to the present invention, for example, it is possible to automatically create a video-only digest related to “baseball”.
[0015]
In the above method, the audience rating or audience rating corresponding to the audience layer having a specific user profile may be acquired, and a digest may be created using the audience rating or audience rating.
[0016]
The above user profile includes region, sex, age group, and the like. ADVANTAGE OF THE INVENTION According to this invention, it becomes possible to produce a digest according to the target which distributes a digest image | video as an advertisement by using a user profile, and it becomes possible to create a more effective digest.
[0027]
Moreover, according to this invention, the digest production apparatus suitable for implementation of said method is provided. In addition, a program for causing a computer to execute the process of the above method and a recording medium recording the program are provided, and the computer can execute each step of the above method.
[0029]
DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described below. In the following description of the embodiment, “video” will be described as an example. However, this “video” may include only video, but generally includes audio. Even in the case of only audio without including video, it is possible to create a digest by the same method as in the case of “video”.
[0030]
In the system according to the embodiment of the present invention, the audience rating or degree of viewing for each hour of the program being broadcast or the program reproduced from the recording medium is totaled via the network, and a video of a portion higher than the set threshold is obtained. By extracting, the viewer's interest in the video is determined. Based on the determination result, a video portion having a high audience rating is automatically extracted to create a digest video. In the present specification, the term audience rating may 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 the graph which shows the relationship between the time and audience rating in * month * day. In the present invention, a threshold is set in advance for the audience rating, and a video at a time when the audience rating exceeds the threshold is picked up to create a digest video. In the case of the example of (A), the audience was first picked up when the audience rating exceeded the threshold when the video of the variety program (a), and the second time was the video of the news program (b). Thereafter, every time the audience rating exceeds a threshold, an image of 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 a digest video on the day of month. The digest video in the example of (B) is created based on the audience rating of (A). In this example, a digest video is created from video (a), video (b), and the video when the audience rating exceeds the threshold, in the order of time exceeding the audience rating threshold in (A).
[0033]
In other words, the audience rating indicates the degree of interest of the viewer. In the same program, a video with a high audience rating is a portion where the viewer is highly interested. In addition, a program with a higher audience rating than other programs indicates that the program is highly interested, and the climax scene and promotional video of the program are considered to attract more viewer interest.
[0034]
As described above, according to the present invention, it is possible to automatically detect a video portion with a high audience rating and extract the video portion, thereby creating a digest video that attracts more viewer interest. Note that the graph shown in FIG. 1A uses the audience rating on the vertical axis, but when the number of viewers (referred to as audience rating in this specification) is used on the vertical axis, This is a histogram indicating 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. However, a digest video can be created in the same manner from a program reproduced from a recording medium.
[0037]
FIG. 2 is a diagram illustrating a configuration example of a system according to the first embodiment. The system includes a digest video creation device 1 that creates a digest video, a plurality of viewer terminals 2 that are broadcast reception terminals of each viewer, a broadcast station 3 that provides program content by broadcasting, and a network such as the Internet. 4.
[0038]
The viewer terminal 2 has a broadcast receiving unit 21 that receives a broadcast program from the broadcast station 3, a channel information acquisition unit 22 that constantly acquires channel information that is being viewed on the viewer terminal 2, and a viewer's viewing time at all times. Viewing time measuring unit 23 for measuring, viewing data creating unit 24 for creating viewing data including at least channel information and viewing time, and viewing data for periodically transmitting viewing data to digest video creating apparatus 1 over network 4 And a transmission unit 25.
[0039]
The viewing data created by the viewing data creation unit 24 has, for example, the configuration shown in FIG. When the digest video creation device 1 receives the viewing data, the terminal having transmitted the viewing data receives the viewing time (including a viewing time indicated by the viewing data) of the program having the channel number indicated by the viewing data. ).
[0040]
If the viewer terminal 2 measures the viewing data at short time intervals, a more accurate audience rating can be calculated. Further, if a high-speed network such as an optical network is used in the network 4, the audience rating can be calculated in real time and a digest video can be created in real time. Here, the viewer terminal 2 is, for example, a viewer terminal for which the user has given permission to provide viewing data by member registration.
[0041]
The digest video creation device 1 includes a threshold setting unit 11, a target program designating unit 12, a viewing data acquisition unit 13, an audience rating calculation unit 14, an extraction determination unit 15, and a digest video extraction unit 16. .
[0042]
The threshold setting unit 11 sets a threshold determined by the digest video creator based on past audience rating statistics, analogy based on the total number of terminals, and the like. The threshold value can be set for each time zone (period), such as {19:00 to 20:00, ...}, {morning, noon, evening, midnight}, a week, a month, etc. it can. The target program specifying unit 12 acquires information on the target program from the digest target program list 51 specified by the digest video creator.
[0043]
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 designated by the digest video creator. The time zone and channel may be specified as in the example of FIG. 4, or only one time zone may be specified by specifying one broadcasting station. If a digest target program list including only programs of a specific genre is prepared by designating only programs of a specific genre, a digest video for each genre can be created. One genre can be designated from a plurality of genres, and a digest including only the program of the designated genre can be created.
[0044]
The digest target program list may be included in the digest video creation device, or data may be acquired from the outside as needed via a 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
Audience rating (t) = number of viewing terminals (t) ÷ total number of terminals (t)
Calculated by The number of viewing terminals is the number of terminals 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 that are subject to audience rating aggregation, for example, the number of members of the target service.
[0047]
The extraction determining unit 15 compares the audience rating calculated by the audience rating calculating unit 14 with the threshold set by the threshold setting unit 11. The digest video extraction unit 16 acquires the program content 50 from the broadcast station 3 in real time, extracts a video with a viewer rating higher than the threshold as a digest video based on the comparison result in the extraction determination unit 15, and The video of the low time is cut off to create a digest video.
[0048]
FIG. 5 is a diagram for explaining extraction of a digest video in the first embodiment. FIG. 5 (A) shows an example of the audience rating for each digest target program every 30 seconds. Here, the program ID is information for identifying each digest target program. For example, if the threshold is set to 20%, the audience rating portion surrounded by the double line in FIG. 5A is extracted. FIG. 5B shows a video portion extracted as a digest from the audience rating of FIG.
[0049]
Further, when a digest video is created 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 therefrom. When creating a digest video from a broadcasted program, a video storage device is connected to each viewer terminal, for example, instead of the broadcast station 3 in FIG. 2, and the program is reproduced therefrom. In this case, the relative time from the start time of a certain program is used instead of the viewing time of the viewing data, and the audience rating is used instead of the viewing degree in the third embodiment to be described later. Can be created.
[0050]
FIG. 6 is a digest video creation flowchart according to the first embodiment. First, a threshold specified by the digest video creator for each time zone is set based on past audience rating statistics, analogy based on the total number of terminals, and the like (step S10). Next, the processes in and after step S12 are repeated until the digest target program specified in the digest target program list ends (step S11). If completed, 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 a set threshold value (step S13), and if the audience rating is higher than the threshold value, it is confirmed whether the video of the currently broadcast program is being extracted as a digest video ( Step S14) If extraction has not yet started, extraction starts with the currently broadcast video as a digest video (step S15), and the process returns to step S11. If it is already being extracted, the extraction is continued as it is (step S16), and the process returns to step S11.
[0052]
If it is determined in step S13 that the audience rating is lower than the threshold, extraction is stopped if digest video is being extracted, and if extraction has not started yet, the extraction stopped state is continued as it is (step S17), and the process returns to step S11. .
[0053]
If it is determined in step S11 that the end of the digest target program has been confirmed, it is confirmed whether or not the current video is being extracted as a digest video (step S18). If extraction is in progress, the extraction is terminated (step S19). Then, the digest video creation process ends.
[0054]
In this way, it is possible to extract only the part of the video whose audience rating is higher than the threshold and create a digest video. The digest video may be one 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 from the received viewing data, but directly from the viewer terminal 2. Instead of receiving viewing data, the digest video extraction processing may be performed by obtaining the already calculated viewing rate from an external device that calculates the viewing rate.
[0056]
(Second Embodiment)
In the second embodiment, broadcasting of a program for which a digest video is to be created has already been finished, and for the program whose maximum audience rating has exceeded the threshold, the original video such as a climax scene or a promotion video is mainly used. This is an embodiment in which a knitted short video is acquired and a digest video is created. Note that short videos mainly composed of original videos such as climax scenes and promotion videos are videos prepared in advance.
[0057]
FIG. 7 is a diagram illustrating a configuration example of a system according to the second embodiment. The system includes a digest video creation device 6 that creates a digest video, a plurality of viewer terminals 2 that are broadcast reception terminals of each viewer, a broadcast station 3 that provides program content by broadcasting, and a network such as the Internet. 4.

The threshold setting unit 61 sets a threshold specified by the digest video creator based on past audience rating statistics and analogy based on the total number of terminals. The target program specifying unit 62 acquires information on the target program from the digest target program list 52 specified by the digest video creator.
[0061]
FIG. 8 is a diagram illustrating an example of a digest target program list according to the second embodiment. The example of FIG. 8 is an example of the digest target program list 52 when the video of the climax scene of the program is acquired via the Internet. The program name, program ID, program content URL (Uniform Resource Locator), and time length (climax video Time length) and climax video URL information. In this example, a climax scene video can be acquired by specifying a climax video URL. Moreover, if a digest target program list designating only programs of a specific genre is prepared, a digest video for each genre can be created.
[0062]
The viewing data acquisition unit 63 acquires viewing data from a plurality of viewer terminals 2 and accumulates it as viewing data 53. FIG. 9 is a diagram illustrating an example of viewing data 53 according to the second embodiment. In this example, the viewing data of each viewer terminal 2 is acquired as the viewing data 53 at intervals of 30 seconds, and each includes information such as viewing time, viewer ID, and channel information. Note that the channel information may not be a channel number or the like as long as it specifies program content.
[0063]
The highest audience rating calculation unit 64 calculates the highest audience rating for each digest target program from the viewing data 53 for the program that is the target of the digest video obtained by the target program specifying unit 62 from the digest target program list 52.
[0064]
The extraction determining unit 65 compares the maximum audience rating of each program calculated by the maximum audience rating calculating unit 64 with the threshold set by the threshold setting unit 61. The digest video extraction unit 66 digests the short video 54 (climax scene, promotion video, etc.) mainly composed of the original video with respect to the program whose maximum audience rating is higher than the threshold, based on the comparison result in the extraction determination unit 65. Extract as video and create digest video. A program whose maximum audience rating is lower than the threshold is not used to create a digest video.
[0065]
When a plurality of short videos 54 composed mainly of original videos in a single program are designated, the order to be added to the digest video may be arranged in the order of processing, or in the order of videos with the highest audience rating in the program. You may arrange them.
[0066]
FIG. 10 is a digest video creation flowchart in the second embodiment. First, a threshold specified by the digest video creator is set based on past audience rating statistics and analogy based on the total number of terminals (step S20), and the maximum viewing for each program is obtained from the viewing data acquired from each viewer terminal 2. The rate is calculated (step S21).
[0067]
Next, the digest target programs specified in the digest target program list 52 are acquired one by one (step S22). At this time, if all the digest target programs have already been acquired and those processes have been completed (step S23), the process is terminated.
[0068]
For the acquired digest target program, the calculated maximum audience rating is compared with a set threshold (step S24), and if the audience rating is higher than the threshold, the short video mainly composed of the original video of the program 54 is extracted as a digest video (step S25), and the process returns to step S22. If the maximum audience rating is lower than the threshold value in step S24, the program returns to step S22 without creating a digest video for the program.
[0069]
In the second embodiment, the maximum audience rating is calculated for each program and compared with a threshold value. However, if the digest video can be extracted in comparison with the threshold value, the maximum audience rating is not necessary. In order to measure the audience rating of each program as a whole, the average audience rating from the start to the end of each program is calculated for each program and used for comparison with a threshold for extracting digest video Good.
[0070]
In this way, it is possible to create a digest video that collects short videos mainly composed of original videos such as climax scenes and promotional videos of programs with high audience ratings.
[0071]
In the second embodiment, the digest video creation device 6 receives viewing data from a plurality of viewer terminals 2 and calculates the viewing rate by itself from the received viewing data. The calculated audience rating may be acquired from the device.
[0072]
(Third embodiment)
In the first and second embodiments, the audience rating is used as an index for extracting a video to be used as a digest, but the audience rating may be used instead of the audience rating. Hereinafter, an embodiment in the case where the audience power is used will be described. In the following description, it is assumed that the number of viewers (= the number of viewing data extraction devices corresponding to the video viewing device from which the digest creation target video is reproduced or the number of viewers for each viewing data extraction device can be grasped. Is a number that includes the number of viewers). In the third embodiment, a video (including a broadcast program) reproduced by the video viewing device 90 is a digest creation target.
[0073]
FIG. 11 is a system configuration diagram showing the present embodiment. As shown in the figure, this system acquires a viewing data extracting 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 extracting devices 100. And a digest video creation device 110 that generates a digest video based on the digest video.
[0074]
The viewing data extraction apparatus 100 includes a viewing data extraction unit 101 and a viewing data transmission unit 102. The viewing data extraction unit 101 obtains information about jumps and search information used for video search during viewing from the video viewing device 90 and information about the jumped part and the part that was actually played back in relation to the processing. Also, a content ID (hereinafter, this information is referred to as viewing data) that identifies the video data currently being viewed is extracted.
[0075]
FIG. 12 shows a configuration example of viewing data. Among (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]
Note that the video viewing device 90 is a device that plays back video such as a DVD player, a video deck, and an STB for VOD that is played back by receiving video distribution from a broadcast or a network. That is, “video” in the present embodiment includes video distributed by broadcasting, video distributed via a network, 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 a viewing data receiving unit 111 that receives viewing data transmitted from the plurality of viewing data extraction devices 100 via the communication network 105, and stores the viewing data for each viewing data extraction device or viewer. A viewing data storage unit 112, a video data storage unit 113 that stores the same video as the video being viewed on the video viewing device 90, and a digest video creation unit 114.
[0079]
The digest video creation unit 114 uses the viewing data of video data for which a digest video is to be created from the viewing data stored in the viewing data storage unit 112, and a plurality of viewings are performed every certain unit time during content playback. In the data extraction apparatus 100, the viewing degree of how many pieces of the viewing data extraction apparatus 100 have been viewed by the content is histogrammed, a part of the video having a high degree of viewing degree is extracted from the histogram, and the part is taken as the video data storage unit 113. Take them out and connect them together to edit 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]
In addition, the viewing information receiving unit 111 and the viewing data storage unit in the digest video creation device 110 may be in a different device from the digest video creation device 110. In this case, the digest video creation device 110 can be viewed from that device as needed. Obtain and use data. Further, the video data storage unit 113 may be placed on an external device.
[0082]
FIG. 13 is an operation flow of this system in the third embodiment. First, the viewing data extraction apparatus 100 extracts viewing data from the video viewing apparatus 90 (step 101). In this embodiment, the viewing data is extracted in real time at the same time as viewing the video. However, the viewing data may be received from the video viewing apparatus 90 in a lump after viewing the video.
[0083]
Then, the viewing data transmitting unit 102 in the viewing data extracting apparatus 100 transmits the extracted viewing data to the digest video creating apparatus 110 via the communication network 105 (step 102). The communication network 105 may be any communication network, wired or wireless, as long as it can transmit viewing data.
[0084]
Subsequently, the digest video creation device 110 receives viewing data from the plurality of viewing data extraction devices 100 via the communication network 105 (step 103). The received viewing data is accumulated in the viewing data storage unit 112 for each content (for example, broadcasted program, movie, etc.) (step 104). An example of viewing data stored in the viewing data storage unit 112 is shown in FIG. The example shown in FIG. 14 is an example in which “reproduced” viewing data is sequentially stored for each content ID.
[0085]
Then, at the time of creating the digest video, a histogram is created by accumulating the portions actually viewed by the viewer using the stored viewing data (step 105).
[0086]
The procedure for creating the histogram will be described in detail below with reference to FIG. Based on this histogram, the video data of the content that is the subject of the digest creation, which is stored in the video data storage unit 113 around the part where the viewer is actually viewing, is extracted and connected to create a digest video (Step 106).
[0087]
FIG. 15 is a flowchart showing a procedure for creating a histogram in the third embodiment of the present invention. In the following processing, the processing from step 111 to step 115 is performed for each piece of viewing data, and a histogram is created.
[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 discriminating section may be of any length. In this discrimination section, if it represents that this section has been viewed, 1 is added to the histogram of that section, and nothing is performed if it is not viewed (steps 112 to 113).
[0089]
Then, it is determined whether the viewing discrimination section is not the last of the video data (step 114). If it is not the last, the next 5 seconds are set as the viewing discrimination section (step 115). When the presence / absence of viewing is determined for the entire video data of the target content, histogram data for the viewing section is similarly added to the next viewing data. The same process is repeated 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]
In order to create a digest, first, a section in the histogram where the viewing degree is higher than a certain threshold is selected (step 121), and an image corresponding to the section is extracted from the video data storage unit 113 (step 122). Then, the extracted videos are connected to create a digest video (step 123). The threshold value is determined in advance based on past audience power statistics, the total number of viewers, and the like. This threshold value may be a certain absolute number (for example, extracting a part viewed by 100 or more people), or may be a number considering the total number of viewers. Note that when the total number of viewers is taken into account, this is equivalent to providing a threshold value based on the audience rating.
[0092]
In addition, by using the total number of viewers, it is also possible to obtain a digest based on the audience rating as in the first and second embodiments by obtaining an audience rating graph from the histogram.
[0093]
In the present embodiment, the digest video creation device creates a histogram based on viewing data. However, a digest may be created by acquiring a created histogram from the outside.
[0094]
As described above, since a portion viewed by a larger number of viewers can be edited as a digest, an effective digest reflecting the viewer's interest can be generated. In the third embodiment as well, as in the second embodiment, a digest video is created using a short video for a program having a maximum viewing degree exceeding a predetermined threshold in a plurality of programs. Is also possible.
[0095]
As described above, according to the first to third embodiments of the present invention, it is possible to extract a video having a high audience rating of an actually broadcast program, or in a reproduced video. By extracting videos viewed by many viewers, it is possible to automatically create a digest video in which only scenes of interest to the viewers are collected. Also, if you extract short videos composed mainly of original videos such as climax scenes and promotional videos of programs with high audience ratings or audiences as digest videos, you can promote stored video content such as programs and videos on demand. Can also be used.
[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.
[0097]
That is, in the system of the first and second embodiments, the audience rating is obtained using the audience viewing data corresponding to a specific user profile, and a video is extracted based on the audience rating to create a digest. Further, in the system according to the third embodiment, a viewing degree is obtained by using viewing data of a viewer corresponding to a specific user profile, and a video is extracted based on the viewing degree to create a digest.
[0098]
Hereinafter, as an example, the fourth embodiment will be specifically described based on the configuration of the third embodiment.
[0099]
FIG. 17 is a system configuration diagram showing the fourth embodiment of the present invention. In the following description, the same components as those in the third embodiment are denoted by the same reference numerals, and the description thereof is omitted.
[0100]
In the system of the fourth embodiment, instead of the viewing data storage unit 112 in the system of the third embodiment, not only viewing data but also a video viewing device 90 is placed for each video content and each viewing data extraction device. The viewing data storage unit 122 that accumulates the viewer's user profile such as the region where the video viewing device 90 is used and the gender and age of the viewer using the video viewing device 90 is used. When creating a viewing histogram, the digest video creation unit 114 uses a user profile such as a specific region, a specific age group, and a specific gender to create a histogram that limits the target range of the viewer. Create a digest video. An example of a user profile stored in the viewing data storage unit 122 is shown in FIG.
[0101]
That is, for example, a digest video about a viewer who lives in a specific area can be created. In addition, for example, it is possible to create a digest video for people in the 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 FIG.
[0103]
After digest video creation device 110 receives viewing data (similar to steps 101 to 103), when viewing data is stored, user profiles such as the region, age, and gender in which the viewer exists are stored simultaneously (steps). 201). Then, the digest video creation unit 114 creates a histogram using only viewing data in a specific range such as a specific region, a specific age group, and a specific gender based on the viewer information at the time of generating the viewing location histogram (step S1). 202). Then, a digest video reflecting a specific range of preferences is created. The digest creation method itself is the same as in the third embodiment (step 106).
[0104]
Note that the user profile used to limit the audience group may combine a plurality of conditions such as combining age and region. In addition to the area, age, and gender, any parameters that can limit the viewer to a certain range may be used.
[0105]
Further, the user profile may be received from the viewing data extracting device when receiving the viewing data and stored, or may be stored in advance in the storage device during user registration or the like. As a method of receiving the viewing data from the viewing data extracting device, there is a method in which a viewer inputs a user profile to the viewing data extracting device using an IC card or the like and the viewing data extracting device transmits the input data. In addition, the ID of the viewing data extraction device and the user profile corresponding thereto are stored in advance in the digest video creation device or a device that can be accessed by this, 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 designates a part of a video that should not be included in a digest is used, and a part specified by the digest restriction filter is not included in the digest. The digest restriction filter can be applied to any system of the first to third embodiments. Here, an example applied to the system of the third embodiment will be described.
[0107]
FIG. 20 is a system configuration diagram showing the fifth embodiment of the present invention. In addition to the system of the third or fourth embodiment, the system of the fifth embodiment includes a digest filter storage unit 135 that accumulates a digest restriction filter that indicates a portion that should not be included in the digest in the video. . This filter is provided for each content as required. This filter includes, for example, one or a plurality of video sections (for example, start time-end time) indicating portions not included in the digest.
[0108]
FIG. 21 is a diagram for explaining a digest creation procedure according to the fifth embodiment of the present invention.
[0109]
After selecting the target range to be reflected in the digest (step 121), using the digest restriction filter stored in the digest filter storage unit 135, the portion that should not be included in the digest from the digest target range generated from the histogram (digest restriction target) (Range) is removed (step 222), and it is set as a new digest target range (step 123).
[0110]
In this way, by using the digest restriction filter, the digest may contain parts that will not be touched when the main part is viewed if the video is shown in advance before the main part distribution or at the initial stage of distribution. In this way, it is possible to prevent the digest distribution from having an adverse effect as an advertisement.
[0111]
It is also possible to replace the digest restriction filter every specified period after distribution of video data and use a different digest restriction filter. In this way, for example, by gradually relaxing the restriction filter and increasing the target scene of the digest, creating a digest that incorporates a more effective scene for viewers who were not interested in the initial digest Is possible.
[0112]
(Sixth embodiment)
In the sixth embodiment, a digest priority filter that indicates a portion that should be preferentially included in a digest is used, and a video portion specified by the digest priority filter is preferentially included in the digest. The digest priority filter can also be applied to any system of the first to third embodiments. Here, an example applied to the system of the third embodiment will be described.
[0113]
The system of the sixth embodiment includes a digest filter storage unit 135 that accumulates a digest priority filter that indicates a portion that should be preferentially included in the digest in addition to the system of the third embodiment or the fourth embodiment. That is, the system of the sixth embodiment is a system in which a digest priority filter is stored in the digest filter storage unit 135 in place of the digest restriction filter in the system configuration diagram shown in FIG.
[0114]
FIG. 22 is a diagram for explaining a digest creation procedure according to the sixth embodiment of the present invention.
[0115]
After selecting the first target range to be reflected in the digest (step 121), using the digest priority filter stored in the digest filter storage unit, a new histogram is created by adding the added frequency of the priority part on the histogram ( In step 324), a new digest target range is selected using the same, and a digest is created (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 a priority filter, a scene in which an actor desired to be shown in a digest is shown, a scene incorporated for a digest, etc. It is possible to effectively capture a scene that is desired to be captured.
[0117]
In addition, the digest priority filter may be replaced for each designated 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 composed only of the intention of the sponsor is closer to the actual viewing entity, and video that could not be captured with one digest is captured over time It is possible to change the digest video efficiently.
[0118]
(Modifications of the fifth and sixth embodiments)
Note that the digest priority filter in the sixth embodiment can be configured so that the part specified by the filter is always included in the digest in the same manner as the digest restriction filter in the fifth embodiment. is there. Conversely, the digest restriction filter may be configured to reduce the viewing degree of the part specified by the digest restriction filter, like the digest priority filter in the sixth embodiment.
[0119]
Also, without distinguishing between digest restriction filter and digest priority filter, the audience power is added to or subtracted from one or more parts of the video according to the content of the video from the beginning to the end of a certain content. Such a filter can also be used. In this case, the unit of addition or subtraction is not necessarily 1. For example, a value to be added can be set to a large value for a part that is particularly desired to be included in the digest, and a value to be subtracted can be set to a large value for a part that is not particularly desired to be included in the digest.
[0120]
(Seventh embodiment)
In the seventh embodiment, a digest is created in consideration of whether the viewer has previously viewed the digest. Although the processing method in the present embodiment can be applied to any system in the first to third embodiments, here, an example based on the system in the third embodiment will be described.
[0121]
FIG. 23 is a system configuration diagram showing the 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. A viewing data storage unit 142 that stores information on whether or not the digest is being viewed is also used.
[0122]
The digest video creation unit 114 creates a histogram for only the viewer who has seen the digest and a histogram for only the viewer who has not seen the digest, obtains the difference, and calculates the difference under normal conditions, for example. Recreate the digest taking into account the original digest you created.
[0123]
FIG. 24 is an operation flow of this system in the seventh embodiment of the present invention.
[0124]
After receiving the viewing data from a plurality of viewing data extracting devices (steps 101 to 103), when the viewing data is stored in the viewing data storage unit 142, information indicating whether the viewer has previously viewed the digest is stored simultaneously. (Step 301). In creating a new viewing histogram, the digest video creation unit 114 creates a histogram for only the viewer who is viewing the digest and a histogram for only the viewer who has not viewed the digest, and obtains the difference between them (step 302). Thereafter, from the difference, an addition / deletion portion in the original digest is determined, and a new digest is created. (Step 303).
[0125]
As an example, whether or not a certain viewer is watching the digest can use information about whether or not the viewing data is received after digest distribution and whether the viewer is in the digest distribution target area. . If the viewer meets these conditions, it can be assumed that the viewer is already watching the digest.
[0126]
Next, the procedure for creating a digest will be further described with reference to FIG.
[0127]
Compare the histogram of viewers who watched the digest video with the histogram of viewers who did not watch the digest, and subtract the histogram value of viewers who did not watch the digest from the histogram value of viewers who saw the digest video. Then, the difference is obtained (viewing degree difference in the figure, step 411).
[0128]
Then, a portion having a large positive difference is set as an added portion, a negatively large portion is set as a deleted portion (step 412), and the original digest is re-edited to create a new digest (step 413). That is, among the parts having a large difference, 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. In addition, the portion that is not included in the video range of the original digest is left as it is, and the portion that was included in the original video range is deleted. In addition, it can be judged using a threshold value, for example, how much difference is added or deleted.
[0129]
As described above, if the viewing point etc. shifts over time by using information indicating that the digest is viewed or not, a new histogram is created based on the viewing status of the new viewer who has viewed the digest. It is possible to create a new effective digest that reflects the deviation from the initial viewing location.
[0130]
In addition, the digest can be corrected by using a difference between a histogram created at a certain time and a histogram created at another time, instead of the difference using information that is not seen when the digest is viewed. This makes it possible to create a digest that takes into account the passage of time.
[0131]
In order to apply this embodiment to the first embodiment, a difference in audience rating may be obtained and the same processing may be performed.
[0132]
A part or all of the functions of each processing unit in the digest video creation apparatus according to each embodiment of the present invention is configured by a computer program, and the program is executed using, for example, the computer shown in FIG. A form can be realized. 26 includes 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]
Further, the above program is recorded and stored in a computer-readable recording medium such as an FD (floppy (registered trademark) disk), MO, ROM, memory card, CD-ROM, DVD, removable disk, or the like. Can be distributed. The program can also be provided through a network such as the Internet or 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 reflecting a user profile. Therefore, it is possible to create a digest focusing on a specific user profile. For example, by specifying an area that is one of the user profiles, a digest that more effectively reflects the area rooted in the area, such as videos of sports teams closely related to the area and videos of popular shops in the area Can be created.
[0135]
Furthermore, by specifying the age group and gender, it is possible to create and distribute a digest that is specific to the target viewer when selling content. It is also possible to flexibly handle requests for video content that is desired to be included in the digest from video content distribution companies and production companies, and actors' affiliated offices. In addition, the restriction filter is gradually relaxed to increase the number of scenes to be digested, and it is possible to create a digest that incorporates a more effective scene for viewers who are not interested in the initial digest.
[0136]
Furthermore, it is also possible to create a digest in consideration of whether or not the digest is viewed after the digest is transmitted once.
[0137]
The present invention is not limited to the above-described embodiments, and various modifications and applications are possible within the scope of the claims.
[0138]
【The invention's effect】
