Information processing apparatus, video distribution system, information processing method, and recording medium

1. An information processing apparatus comprising:

a memory storing instructions; and

one or more processors configured to execute the instructions to:

acquire a video material;

acquire a generation condition from a creator in order to generate a digest video;

generate structural information indicating a structure of the digest video which is generated from the video material based on the generation condition, and store the generated structural information and attached information concerning the creator in a database; and

acquire, upon receiving a request for the structural information indicating at least a portion of the attached information, the structural information corresponding to the portion of the attached information from the database, and send the acquired structural information to a request originator.

2. The information processing apparatus according to claim 1 , wherein the generation condition indicates at least one of attributes of the creator, a length of the digest video, and information specifying a subject to be included in the digest video.

3. The information processing apparatus according to claim 1 , wherein the generation condition includes at least one of a time zone during which a viewer views the digest video and a date and time when the material video used to generate the digest video was generated.

4. The information processing apparatus according to claim 1 , wherein

the processor extracts a plurality of important scenes from the video material based on the generation condition; and

the structural information includes information indicating videos of the plurality of important scenes being extracted.

5. The information processing apparatus according to claim 4 , wherein the processor extracts features for each of a plurality of scenes included in the video material, calculates a score of importance of the features based on the generation condition, and extracts each scene for which the score of importance exceeding a predetermined threshold, as one of the important scenes.

6. The information processing apparatus according to claim 4 , wherein

the structural information includes information indicating each related video that is related to the important scenes; and

the structural information includes at least one of a previous video related to the important scenes, a video related to a subject appearing in the important scenes, and a commentary video related to the important scenes.

7. The information processing apparatus according to claim 1 , wherein

the processor acquires respective generation conditions from a plurality of creators; and

the processor generates the structural information based on the respective generation conditions acquired from the plurality of creators.

8. A video distribution system comprising:

the information processing apparatus according to claim 1 ;

the database configured to store the structural information generated by the information processing apparatus;

a video material database configured to store the video material; and

a distribution device configured to distribute the digest video,

wherein the distribution device

acquiring, from the database, the structural information being requested when receiving a request of the structural information from a playback device and sending the acquired structural information to the playback device; and

acquiring a video of an important scene included in the structural information when receiving a playback request indicating the structural information from the playback device, and sending the acquired video to the playback device.

9. An information processing method performed by a computer and comprising:

acquiring a video material;

acquiring a generation condition from a creator in order to generate a digest video;

generating structural information indicating a structure of the digest video which is generated from the video material based on the generation condition, and storing the generated structural information and attached information concerning the creator in a database; and

acquiring, upon receiving a request for the structural information indicating at least a portion of the attached information, the structural information corresponding to the portion of the attached information from the database, and sending the acquired structural information to a request originator.

10. A non-transitory computer-readable recording medium storing a program, the program causing a computer to perform a process comprising:

acquiring a video material;

acquiring a generation condition from a creator in order to generate a digest video;

generating structural information indicating a structure of the digest video which is generated from the video material based on the generation condition, and storing the generated structural information and attached information concerning the creator in a database; and

acquiring, upon receiving a request for the structural information indicating at least a portion of the attached information, the structural information corresponding to the portion of the attached information from the database, and sending the acquired structural information to a request originator.
