Abstract

A local media player in network communication with a remote storage system stores a portion of content. It then compares the portion of content stored on the local media player with content stored on the remote storage system to determine if the portion of content is duplicated on the remote storage system. If so, the portion of content stored on the local media player is replaced with a pointer to a duplicate portion of content stored on the remote storage system. The portion of content is played back by the local media player at least in part by receiving the duplicate portion of content from the remote storage system if the portion of content has been replaced by a pointer, or by accessing the portion of content stored on the local media player if the portion of content has not been replaced by a pointer.

Claims

1. A method to be performed by a local media player in network communication with a remote storage system, the method comprising the steps of:

storing a portion of content on the local media player;

comparing the portion of content stored on the local media player with content stored on the remote storage system to determine if the portion of content is duplicated on the remote storage system;

replacing the portion of content stored on the local media player with a pointer to a duplicate portion of content stored on the remote storage system if the portion of content is duplicated on the remote storage system; and

playing back the portion of content at least in part by receiving the duplicate portion of content from the remote storage system if the portion of content has been replaced by a pointer, or by accessing the portion of content stored on the local media player if the portion of content has not been replaced by a pointer.

2. The method of claim 1, wherein the step of playing back the portion of content at least in part by receiving the duplicate portion of content from the remote storage system comprises causing the remote storage system to stream the duplicate portion of content to the local media player.

3. The method of claim 1, wherein the replacing step, when performed, frees up storage space on the local media player for additional content storage.

4. The method of claim 1, wherein the comparing step is initiated at least in part by the passage of a predetermined amount of time.

5. The method of claim 1, wherein the comparing step is initiated at least in part by the local media player recording a predetermined amount of content.

6. The method of claim 1, wherein the portion of content comprises at least one of video content, audio content, image content, and text content.

7. The method of claim 1, wherein the local media player comprises a digital video recorder.

8. The method of claim 7, wherein the digital video recorder is implemented in a set-top terminal.

9. The method of claim 1, wherein the remote storage system comprises a server.

10. The method of claim 1, further comprising the step of storing on the remote storage system a duplicate set of pointers that substantially duplicates a set of pointers placed on the local media player.

11. The method of claim 10, further comprising the step of placing the duplicate set of pointers on a second local media player.

12. The method of claim 11, wherein the placing step is performed when replacing the local media player with the second local media player.

13. The method of claim 1, wherein the comparing step comprises identifying the portion of content stored on the local media player.

14. The method of claim 13, wherein the identifying is performed at least in part with reference to a time during which the portion of content was stored on the local media player.

15. The method of claim 13, wherein the identifying is performed at least in part with reference to a channel from which the portion of content was received by the local media player.

16. The method of claim 13, wherein the identifying is performed at least in part with reference to metadata associated with the portion of content.

17. The method of claim 13, wherein the identifying is performed at least in part with reference to a listing schedule.

18. The method of claim 1, wherein the comparing step comprises comparing data constituting the portion of content stored on the local media player with data constituting one or more portions of content stored on the remote storage system.

19. The method of claim 1, wherein the comparing step utilizes one or more data deduplication techniques.

20. The method of claim 1, wherein the step of playing back the portion of content at least in part by receiving the duplicate portion of content from the remote storage system comprises manipulating the pointer.

21. The method of claim 20, wherein the pointer is formatted as a command in conformance with a Hypertext Transfer Protocol.

22. The method of claim 20, wherein manipulating the pointer comprises utilizing the pointer as a parameter in a subroutine call.

23. The method of claim 1, wherein the local media player comprises distinct software modules, each of the distinct software modules being embodied on a non-transitory computer-readable storage medium, wherein the distinct software modules comprise a local storage manager module, a content comparison module, and a local recording manager module, and wherein:

the storing and replacing steps are carried out by the local storage manager module executing on at least one hardware processor;

the comparing step is carried out by the content comparison module executing on the at least one hardware processor; and

the playing back step is carried out by the local recording manager module executing on the at least one hardware processor.

24. A computer program product comprising a tangible, non-transitory computer readable storage medium having computer readable program code embodied therewith, the computer readable program code comprising computer readable program code configured to:

store a portion of content on a local media player;

compare the portion of content stored on the local media player with content stored on a remote storage system to determine if the portion of content is duplicated on the remote storage system;

replace the portion of content stored on the local media player with a pointer to a duplicate portion of content stored on the remote storage system if the portion of content is duplicated on the remote storage system; and

play back the portion of content at least in part by receiving the duplicate portion of content from the remote storage system if the portion of content has been replaced by a pointer, or by accessing the portion of content stored on the local media player if the portion of content has not been replaced by a pointer.

25. A local media player in network communication with a remote storage system, the local media player comprising:

a memory; and

at least one processor, coupled to the memory, and operative to;

store a portion of content on the local media player;

compare the portion of content stored on the local media player with content stored on the remote storage system to determine if the portion of content is duplicated on the remote storage system;

replace the portion of content stored on the local media player with a pointer to a duplicate portion of content stored on the remote storage system if the portion of content is duplicated on the remote storage system; and

play back the portion of content at least in part by receiving the duplicate portion of content from the remote storage system if the portion of content has been replaced by a pointer, or by accessing the portion of content stored on the local media player if the portion of content has not been replaced by a pointer.

26. A local media player in network communication with a remote storage system, the local media player comprising:

means for storing a portion of content on the local media player;

means for comparing the portion of content stored on the local media player with content stored on the remote storage system to determine if the portion of content is duplicated on the remote storage system;

means for replacing the portion of content stored on the local media player with a pointer to a duplicate portion of content stored on the remote storage system if the portion of content is duplicated on the remote storage system; and

means for playing back the portion of content at least in part by receiving the duplicate portion of content from the remote storage system if the portion of content has been replaced by a pointer, or by accessing the portion of content stored on the local media player if the portion of content has not been replaced by a pointer.
