Description

  The present invention relates to a digest distribution list generation server and a digest distribution list generation program that search for content based on a received request, further extract a searched distribution content candidate, generate a distribution list, and transmit it.

  In conventional broadcast-type content such as broadcast video, many users refer to one content, so content for everyone is distributed, and content that matches user preferences cannot be distributed. It was.

  However, with the recent development of information devices, content that meets user preferences has been distributed. For example, it is possible to search from a vast number of contents using a keyword or the like of the content desired by the user, and refer to the searched content. It is also possible to extract important scenes from contents broadcast for a long time, such as dramas and movies, and let the user refer to them. Thereby, the user can grasp the drama and the story of the video within a limited time. In this way, it is required to generate digest content from content and allow the user to browse it. Since the number of contents and combinations of people's tastes are enormous, it is difficult to create digest contents in advance through human intervention. Yes.

  For example, as a method to create a digest video that semantically summarizes the video content without human intervention, create a digest video by entering video information including an index that defines the event that occurred in the video stream. There exists an apparatus (for example, patent document 1). Here, the index information is metadata as video additional information. In the digest creation device described in this patent decentralization 1, it is possible to digitize the video content by generating numerical video information that expresses the content of the video information by changing the numerical value. The contents of information can be easily analyzed with a computer.

  On the other hand, there is also a content summarization system that automatically generates several types of typical summary content from the content and enables selection of the summary content that suits the user's interest (for example, Patent Document 2). According to the content summarization system described in Patent Document 2, annotation data is converted into a feature amount based on metadata including annotation data that is a description of the content, and the summary content is converted based on the importance of the feature amount. Can be created.

  In addition, the video data is divided into scenes, and various feature quantities are detected by detecting whether each scene has a face area or the end of a silent section, and each feature quantity is weighted and integrated. There is also a video information recording / reproducing apparatus that extracts the important scene and creates a scenario to be used for digest reproduction by evaluating the value obtained by the above (for example, Patent Document 3). According to the video information recording / reproducing apparatus described in Patent Document 3, the scenarios are read and reproduced in order from the scenario with the highest priority.

On the other hand, when content is produced manually, in order to make the content attractive, generally not only the most desired scene but also the previous stage and preconditions of the scene and the subsequent progress of the desired scene. Etc. are combined to form one story. Specifically, in a soccer game, instead of playing back only the scene where the team of 贔 屓 scored a goal, the situation of the team before the match, the introduction of the starting member, the goal scene of the opponent team, the end of the match As a result, content that is attractive to the user is created by determining the time distribution of each scene within a predetermined time, such as the situation of the team after the game. At this time, the user's satisfaction is higher when the video time of the goal scene of the niece team is longer than the video time of the goal scene of the opponent team.

  However, in the method described in the above-mentioned patent document, since the digest is created by digitizing the video content using the feature amount or the like, only the video close to a predetermined standard is included in the digest. .

  In other words, in the above-described example, if the feature amount of the goal scene of the niece team is set high, only that scene is reproduced. In this case, for example, there are no scenes at the previous stage such as the situation of the team before the game or introduction of the starting member, and only similar goal scenes are extracted. Moreover, there is a possibility that information such as the final result that is naturally broadcast is not included. As a result, the configuration of the entire content becomes flat, resulting in an unattractive digest video.

  As described above, in the method described in the above-described patent document, scenes desired by the user can be collected. However, as a result of not considering the configuration of the collected contents, only an unattractive digest video can be generated.

  Accordingly, an object of the present invention is to provide a digest distribution list generation server and a digest distribution list generation program capable of generating digest contents attractive to a user.

Then, a request for acquiring “main horse information”, “compete horse information”, and “hole horse information” is transmitted.

  When the detailed information is requested, the content providing server 2a reads the race information table 21, and uses the event location, date, and race number as search keys as the keys, and the “present horse information” and “compete horse information”. , “Anouma information” is extracted to create detailed information, which is transmitted to the digest distribution list generation server 1 in step S205. At this time, the “favorite horse information” includes a horse name and a racehorse ID that uniquely identify the favorite horse, and this favorite horse information can extract a video related to the favorite horse from meta information related to a horse race. it can.

  When the detailed information is received, the distribution video candidate search means 16 of the digest distribution list generation server 1 requests a digest video candidate from the content providing server 2a based on this detailed information. At this time, based on the digest definition database 11 illustrated in FIG. 7, the digest distribution list generation server 1 determines, based on the detailed information acquired in step S205 from the “racing horse information table” of the “horse racing information database”, “ A request for acquiring “video information related to the horse”, “video information related to the competing horse”, and “video information related to the horse” is transmitted.

  When a digest video candidate is requested, the content providing server 2a reads the racehorse information table 22, and uses the racehorse ID as a key to specify “previous video information”, “pre-race paddock video information”, “follow-up”. Video information ”and“ result video information ”are extracted to generate digest video candidates, and are transmitted to the digest distribution list generation server 1 in step S2076. Here, the video information is information including a URL (position information) where the video is stored, a time code at which a predetermined video is played back in the video stream, and a playback time (scale).

  When the digest video candidate is received, the distribution list generating means 19 of the digest distribution list generating server 1 generates a distribution list in step S208 and transmits the distribution list to the user terminal 4a. This distribution list includes video information related to the favorite horse, video information related to the competing horse, and video information related to the horse. Furthermore, it is preferable that the identifier of the information providing service provider server 3a that is a request destination of the digest video distribution is included in the distribution list.

  Upon receiving the distribution list, the user terminal 4a requests the digest video distribution to the information providing service provider server 3a that is the request destination of the digest video distribution in step S210. In step S211, the information providing service provider server 3a that has received the digest video distribution request from the user terminal 4a requests the content providing server 2a to perform digest video distribution based on the URL included in the digest video information.

The video data stored in the URL may be transmitted to the information providing service provider server 3a, and the information providing service provider server 3a may extract the video data from the video archive based on the cut start time code and scale.

(Digest rule)
Next, an example of calculating the coefficients P, Q, A, and B for the digest rule setting method, specifically, the case of the horse racing described above will be described. Here, the coefficients P, Q, A, and B are calculated according to the digest rule conditions as shown in FIG. As shown in FIG. 12, the video information of the distribution video candidate searched by the distribution video candidate search means 16 is defined by the start time of the preceding video candidate t ₁ and the scale of l ₁ , and the start time of the paddock video candidate Is defined as t ₂ , the scale is defined as l ₂ , the start time of the follow-up video candidate is defined as t ₃ , the scale is defined as l ₃ , the start time of the result video candidate is defined as t ₄ , and the scale is defined as l ₄ . Further, as shown in FIG. 13, the video information of the distribution list generated by the distribution list generating means 19 is defined by the start time of the preceding video as T ₁ and the scale as L ₁ , and the start time of the paddock video is T _2, scale is defined by L _2, the start time of the outright chase video T _3, scale is defined by L _3, actual start time of the video is T _4, scale is defined by L _4.

Further, according to the conditions of the digest rule as shown in FIG. 5, a constraint condition such as Expression 1 is derived from the description “the actual video is 50% of the overall scale”. From the description that “the sum of paddock video and follow-up video does not exceed 40% of the total”, a constraint condition such as Equation 2 is derived. From the description “30% of the total length of the paddock image”, a constraint condition such as Equation 3 is derived. A constraint condition such as Expression 4 is derived from the description “the length of the shading image is 10% of the entire scale”.

From Equation 1 to Equation 4, an equation like Equation 5 can be derived.

Here, the start time t ₁ = 10 seconds of the preceding video candidate, the scale l ₁ = 360 seconds, the start time t ₂ of the paddock video candidate = 200 seconds, the scale l ₂ = 50 seconds, the start time t of the follow-up video candidate It is assumed that ₃ = 5 seconds, the scale l ₃ = 70 seconds, the actual video candidate start time t ₄ = 600 seconds, and the scale l ₄ = 80 seconds. At this time, when Formula 5 is collected on one side, calculation is performed as Formula 6.

Next, a method for calculating the values of A and B will be described. Here, the case where f ₀ <0, f ₁ ≧ 0, f ₂ <0, and f ₃ ≧ 0 will be described.

Since the digest rule condition 1 shown in FIG. 5 states that “the overall scale is 300 seconds”, a calculation formula such as Formula 12 is obtained. Here, the overall scale is L ₀ = 300 seconds.

The condition 2 of the digest rule shown in FIG. 5 is that “the actual video has a length of 50% of the entire scale and is used from the start point”. Accordingly, when the actual video candidate scale length is shorter than 50% of the entire scale, all the actual video candidates are used, and therefore, a calculation formula such as Expression 13 is obtained. On the other hand, when the length of the actual video candidate is longer than 50% of the overall scale, the length of 50% of the entire scale is used from the starting point, and thus a calculation formula such as Expression 14 is obtained.

The condition 3 of the digest rule shown in FIG. 5 is that “the total of paddock video and follow-up video is used when the sum does not exceed 40% of the overall scale”. Desired.

In addition, when the condition 3 of the digest rule shown in FIG. 5 is exceeded, the paddock video is 30% of the total length and the follow-up video is 10% of the total length. In this case, the paddock video is Is used from the center point of the start point and end point, and the follow-up video is used from the end point. " Here, when the paddock image is shorter than 30% of the overall scale, Expression 16 is used, when it is long, Expression 17, when the follow-up image is shorter than 10% of the entire scale, Expression 18 is used, and when it is longer, Expression 19 is used. A calculation formula is obtained.

Since the condition 4 of the digest rule shown in FIG. 5 is that “the preceding video is the length of the actual video, paddock video, and follow-up video from the overall scale, it is used from the end point”, A calculation expression such as Expression 20 is obtained.

Here, A and B are calculated when f ₀ <0, f ₁ ≧ 0, f ₂ <0, and f ₃ ≧ 0, that is, in the following cases.

At this time, the following formulas 22 and 23 are derived from Formula 12, Formula 13, Formula 15 and Formula 20.

Equations 22 and 23 lead to equations like Equation 24.

Here, when X is expressed as shown in Equation 25, an equation like Equation 26 is derived.

Here, A and B are defined as in Expression 27 and Expression 28, respectively.

  In this way, P, Q, x, and α are calculated as shown in Equations 7 to 10, respectively. From the values of f calculated using the values of Equations 7 to 10, A and B are expressed as Equation 27. And is calculated as shown in Equation 28.

Here, when the video information described in the distribution list is calculated, the calculation formula of Formula 29 is derived for X, and finally, the calculation formula of Formula 30 is derived for X.

  As shown in Expression 30, the distribution list includes position information storing files of the preceding video, the paddock video, the chase video, and the actual video, and the time code of the previous video from 270 seconds to 100 seconds. Cut, time code of paddock video 200 seconds to 50 seconds cut, follow-up video time code 5 seconds to 70 seconds cut, actual video time code 600 seconds to 80 seconds cut video information included It is.
