Abstract

The present invention concerns an information processing device which checks whether the content related information retrieved by the content reproducing device is associated with the content pieces recorded in the content reproducing device and which changes the functional operation and selection operation on the screen according to the check result. More specifically, the information processing device comprises: a content related information retrieve unit to retrieve the content related information such as content evaluation results into the content reproducing device; a content management unit to manage content management information such as information about content pieces recorded or received by the content reproducing device and about licenses for the content pieces; and a content control unit to determine a method of processing the content related information retrieved by the content related information retrieve unit according to the content management information held by the content management unit.

Claims

1. An information processing device comprising:

a storage unit to store pieces of content;

a receiving unit to receive information related to pieces of content;

a content related information retrieve unit to retrieve a content related information corresponding to the pieces of content stored in the storage unit from the information related to the pieces of content received by the receiving unit; and

a control unit to perform control according to the content related information retrieved by the content related information retrieve unit.

2. An information processing device according to claim 1, further including a content management unit to manage the pieces of content stored in the storage unit by content piece.

3. An information processing device according to claim 2, wherein the content management unit manages information about licenses for the pieces of content recorded in the storage unit or received by the receiving unit.

4. An information processing device according to claim 2, wherein the control unit controls the content related information retrieved by the content related information retrieve unit so as to display information about the available pieces of content based on content management information managed by the content management unit.

5. An information processing device according to claim 1, further comprising a content management unit capable of managing the content by scene;

wherein the content related information includes scene information representing a predetermined scene of content;

wherein the content related information retrieve unit can retrieve the content related information including the scene information;

wherein the control unit performs control to distinguish and output a method of use of the scene-based content related information retrieved by the content related information retrieve unit according to the content management information held in the content management unit.

6. An information processing device according to claim 1, wherein the content related information includes information about evaluations or recommendations of the pieces of content.

7. An information processing device according to claim 1, wherein the content related information includes advertisement information or publicity information.

8. An information processing device according to claim 1, wherein the content related information is retrieved from the Internet.

9. An information processing device according to claim 2, wherein the control unit performs control to change a method of selecting pieces of content to be moved, copied or deleted according to the content management information managed by the content management unit and the content related information retrieved by the content related information retrieve unit.

10. An information processing device comprising:

a storage unit to store video and/or voice data and management information used to manage the video and/or voice data in units of video and/or voice data;

a receiving unit to receive information about video and/or voice data;

an extraction unit to extract information about the video and/or voice data stored in the storage unit from among the information about the video and/or voice data received by the receiving unit; and

a control unit to change a method of reproducing the information about the video and/or voice data extracted by the extraction unit according to the information about the video and/or voice data identified based on management information.

11. An information processing method comprising:

a storing step to store pieces of content;

a receiving step to receive information about the pieces of content;

a content related information retrieving step to retrieve information about content pieces stored by the storing step from among the information about the content pieces received by the receiving step; and

a control step to perform control according to the information about the content pieces retrieved by the content related information retrieving step.

12. An information processing method according to claim 11, further including a content management step to manage the content pieces stored by the storing step in units of content pieces.

13. An information processing method according to claim 12, wherein the content management step manages information about licenses for the content pieces stored by the storing step or received by the receiving step.

14. An information processing method according to claim 12, wherein the control step controls the content related information retrieved by the content related information retrieving step so as to display information about available pieces of content based on the content management information managed by the content management step.
