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:

a calculation unit configured to determine, on the basis of a viewing history of a play list indicating contents adopted as a playback target chosen from among a plurality of contents, a predetermined value for the play list, and calculates a priority level about a storage unit temporarily storing the contents, for each of the contents, by adding the predetermined value of the play list in which the content is adopted as the playback target.

2. The information processing apparatus according to claim 1, wherein when there is no viewing history of the playlist, the calculation unit calculates, for each of the contents, the priority level by adding the predetermined value for a number of play lists in which the content is adopted as the playback target.

4. The information processing apparatus according to claim 1, wherein the contents are contents in units of scenes.

3. (canceled)

5. An information processing method comprising:

a calculation step in which an information processing apparatus determines, on the basis of a viewing history of a play list indicating contents adopted as a playback target chosen from among a plurality of contents, a predetermined value from the play list, and calculates a priority level about a storage unit temporarily storing the contents, for each of the contents, by adding the predetermined value of the play list in which the content is adopted as the playback target.

6. A program for causing a computer to function as a calculation unit configured to calculate, on the basis of a viewing history of a play list indicating contents adopted as a playback target chosen from among a plurality of contents, a predetermined value for the play list, and calculates a priority level about a storage unit temporarily storing the contents, for each of the contents, by adding the predetermined value of the play list in which the content is adopted as the playback target.

7. An information processing system comprising:

a first information processing apparatus; and

a second information processing apparatus,

the information processing system further comprising;

a storage unit configured to temporarily store contents;

a calculation unit configured to determine, on the basis of a viewing history of a play list indicating contents adopted as a playback target chosen from among a plurality of the contents, a predetermined value for the play list, and calculates a priority level about the storage unit, for each of the contents;

by adding the predetermined value of the play list in which the content is adopted as the playback target;

a control unit configured to delete contents stored in the storage unit, on the basis of the priority level calculated by the calculation unit.

8. The information processing system according to claim 7, wherein, there is no viewing history of the play list, the calculation unit calculates, for each of the contents, the priority level by adding the predetermined value for a number of play lists in which the content is adopted as the playback target, and

on the basis of the priority level calculated by the calculation unit, the control unit determines the content that is to be stored to the storage unit before the content is played back, and stores the content to the storage unit.
