Abstract

According to one embodiment, in an information processing method, a content providing source is accessed to periodically try to acquire content, the acquisition success ratio of the content is managed based on a content acquisition try result, and saving of the acquired content is controlled based on the acquisition success ratio.

Claims

1. An information processing apparatus comprising:

an acquisition unit configured to access a content providing source to acquire content;

an acquisition control unit configured to control the acquisition unit to acquire the content, and retry acquiring the content at a predetermined timing when the content has failed to be acquired;

a management unit configured to manage an acquisition success ratio of the content based on an acquisition result of the content acquired by the acquisition control unit; and

a saving control unit configured to control, based on the acquisition success ratio, saving of the content acquired by the acquisition unit.

2. An apparatus according to claim 1, wherein

the acquisition control unit controls acquisition of first content from a first content providing source, and controls acquisition of second content from a second content providing source,

the management unit manages an acquisition success ratio for each of the first content and the second content, and

the saving control unit determines, based on the acquisition success ratio for each of the first content and the second content, necessity/nonnecessity of saving the first content and the second content, and controls, based on the determination result, saving of the first content and the second content which are acquired by the acquisition unit.

3. An apparatus according to claim 1, wherein

the acquisition control unit controls, based on playback control information for playing back first content and second content, acquisition of the first content from a first content providing source, and acquisition of the second content from a second content providing source,

the management unit manages an acquisition success ratio for each of the first content and the second content, and

the saving control unit determines, based on the acquisition success ratio for each of the first content and the second content, necessity/nonnecessity of saving the first content and the second content, and controls, based on the determination result, saving of the first content and the second content which are acquired by the acquisition unit.

4. An apparatus according to claim 1, wherein the saving control unit saves the content based on an acquisition success ratio lower than a specified value, and does not save the content based on an acquisition success ratio not lower than the specified value.

5. An apparatus according to claim 1, wherein the acquisition control unit tries, a predetermined number of times at a first time interval, to acquire the content which has failed to be acquired, and tries, a predetermined number of times at a second time interval longer than the first time interval, to acquire the content which has failed to be acquired even when acquisition of the content has failed after the predetermined number of times of trying at the first time interval.

6. An apparatus according to claim 1, wherein

the acquisition control unit periodically tries to acquire the content which has failed to be acquired, and further periodically tries to acquire the content even after acquisition of the content has succeeded,

the management unit updates the acquisition success ratio of the content based on the periodical tries to acquire the content using the acquisition control unit, and

the saving control unit determines necessity/normecessity of saving the content based on the updated acquisition success ratio, and controls saving of the content based on the determination result.

7. An apparatus according to claim 6, wherein the saving control unit deletes the content in a saving destination by updating the acquisition success ratio of the content which is lower than a specified value to the acquisition success ratio of the content which is not lower than the specified value.

8. An apparatus according to claim 3, wherein

the acquisition control unit tries to acquire the first content and the second content based on the playback control information,

the management unit updates the acquisition success ratio for each of the first content and the second content based on the tries to acquire the first content and the second content using the acquisition control unit, and

the saving control unit determines necessity/nonnecessity of saving the first content and the second content based on the updated acquisition success ratio, and controls saving of the first content and the second content based on the determination result.

9. An apparatus according to claim 1, wherein the saving control unit deletes, of a plurality of content saved in a saving destination, content whose acquired success ratio is high, when the saving destination has free space smaller than required.

10. An apparatus according to claim 9, wherein the saving control unit preferentially deletes, of a plurality of content whose acquisition success ratios are the same in the saving destination, content whose access try count is large.

11. An information processing method comprising:

accessing a content providing source to periodically try to acquire content;

managing an acquisition success ratio of the content based on a content acquisition try result; and

controlling saving of the acquired content based on the acquisition success ratio.

12. A method according to claim 11, further comprising

periodically trying to acquire the content which has failed to be acquired, and further periodically trying to acquire the content even after acquisition of the content has succeeded,

updating the acquisition success ratio of the content based on the periodical tries to acquire the content, and

controlling saving of the acquired content based on the updated acquisition success ratio.
