Abstract

The present technique relates to an information processing apparatus, an information processing method, a program, and an information processing system capable of efficiently and temporarily storing contents in a case where the contents are played back using a play list. A calculation unit calculates, on the basis of a play list indicating contents adopted as a playback target chosen from among a plurality of contents, a priority level about a cash temporarily storing the contents, for each of the contents. For example, the present technique can be applied to an information processing system and the like performing streaming playback of contents based on MPEG (Moving Picture Experts Group phase)-DASH standard.

Claims

1. An information processing apparatus, comprising:

one or more processors configured to;

acquire a first play list that comprises a set of content from a plurality of contents;

divide each content of the plurality of contents into a plurality of scenes;

determine meta data for each scene of the plurality of scenes based on the first play list;

generate a second play list based on the meta data, wherein

the second play list comprises at least one scene of the plurality of scenes as a playback target, and

the at least one scene is associated with a user preference;

determine a priority level associated with a storage unit for each content of the set of content based on addition of a specific value of the first play list to a specific value of the second play list; and

control, based on the priority level, storage of the set of content in the storage unit prior to a playback of the set of content.

5. The information processing apparatus according to claim 1, further comprising an interface configured to receive information associated with selection of the set of content as the playback target.

6. The information processing apparatus according to claim 1, further comprising an output interface configured to output the set of content.

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

the one or more processors are further configured to determine the specific value of the first play list based on a viewing history of the first play list, and

the viewing history is at least one of a number of times the first play list is viewed or viewing date of the first play list.

2. An information processing method, comprising:

in an information processing apparatus;

acquiring a first play list that comprises a set of content from a plurality of contents;

dividing each content of the plurality of contents into a plurality of scenes;

determining meta data for each scene of the plurality of scenes based on the first play list;

generating a second play list based on the meta data, wherein

the second play list comprises at least one scene of the plurality of scenes as a playback target, and

the at least one scene is associated with a user preference;

determining a priority level associated with a storage unit for each content of the set of content based on addition of a specific value of the first play list to a specific value of the second play list; and

controlling, based on the priority level, storage of the set of content in the storage unit prior to a playback of the set of content.

8. The information processing method according to claim 2, further comprising determining the specific value of the first play list based on a viewing history of the first play list, wherein the viewing history is at least one of a number of times the first play list is viewed or a viewing date and time of the first play list.

3. A non-transitory computer-readable medium having stored thereon, computer-executable instructions, which when executed by a processor of an information processing apparatus, cause the information processing apparatus to execute operations, the operations comprising:

acquiring a first play list that comprises a set of content from a plurality of contents;

dividing each content of the plurality of contents into a plurality of scenes;

determining meta data for each scene of the plurality of scenes based on the first play list;

generating a second play list based on the meta data, wherein

the second play list comprises at least one scene of the plurality of scenes as a playback target, and

the at least one scene is associated with a user preference;

determining a priority level associated with a storage unit for each content of the set of content based on addition of a specific value of the first play list to a specific value of the second play list; and

controlling, based on the priority level, storage of the set of content in the storage unit prior to a play back of the set of content.

9. The non-transitory computer-readable medium according to claim 3, wherein

the operations further comprising determining the specific value of the first play list based on a viewing history of the first play list,

the viewing history is at least one of a number of times the first play list is viewed or a viewing date and time of the first play list.

4. An information processing system, comprising:

one or more processors configured to;

acquire a first play list that comprises a set of content from a plurality of contents; and

a storage unit configured to store the set of content prior to a playback of the set of content,

wherein the one or more processors are further configured to;

divide each content of the plurality of contents into a plurality of scenes;

determine meta data for each scene of the plurality of scenes based on the first play list;

generate a second play list based on the meta data, wherein

the second play list comprises at least one scene of the plurality of scenes as a playback target, and

the at least one scene is associated with a user preference;

determine a priority level associated with the storage unit for each content of the set of content based on addition of a specific value of the first play list to a specific value of the second play list; and

delete the stored set of content from the storage unit, based on the priority level.

10. The information processing system according to claim 4, wherein

the one or more processors are further configured to determine the specific value of the first play list based on a viewing history of the first play list,

the viewing history is at least one of a number of times the first play list is viewed or a viewing date and time of the first play list.
