Abstract

A system and method for sharing playlists within a network includes a first storage device having a first playlist comprising first playlist data corresponding to stored content and a second storage device having a second playlist comprising second playlist data corresponding to stored content. The system also includes an aggregation server in communication with the first storage device and the second storage device that receives the first playlist and the second playlist. The aggregation server aggregates the first playlist data and the second playlist data to form an aggregated playlist having aggregated playlist data and forms an index list corresponding to the aggregated playlist. A first aggregation client is in communication with the aggregation server and receives the index list from the aggregation server.

Claims

1. A method comprising:

forming a first playlist having first playlist data corresponding to stored content within a first storage device;

forming a second playlist having second playlist data corresponding to stored content within a second storage device;

communicating the first playlist and the second playlist to an aggregation server;

aggregating the first playlist data and the second playlist data to form an aggregated playlist having aggregated playlist data;

forming an index list corresponding to the aggregated playlist; and

communicating the index list to a first aggregation client.

2. A method as recited in claim 1 further comprising sorting the index list at the first aggregation client.

3. A method as recited in claim 1 further comprising predicting indices from the index list that correspond to a visualization buffer.

4. A method as recited in claim 3 further comprising predicting indices comprises predicting indices larger than required for a screen display for the visualization buffer.

5. A method as recited in claim 4 further comprising requesting playlist data from the aggregation server based on the indices corresponding to the visualization buffer.

6. A method as recited in claim 1 further comprising selecting a display entry at the first aggregation client to form a selection;

communicating indices corresponding to the selection to the aggregation server;

communicating at least one of the indices to the first storage device; and

communicating content corresponding to the selection from the first storage device to the first aggregation client through a network.

7. A method as recited in claim 6 wherein communicating content corresponding to the selection from the storage device to the first aggregation client through a network comprises communicating content corresponding to the selection from the storage device to the first aggregation client directly through a network.

8. A method as recited in claim 6 wherein the indices corresponding to the selection comprises a playlist holder identifier and a recording identifier.

9. A method as recited in claim 1 wherein the first aggregation client comprises a map for converting indices to a IP address for the first storage device.

10. A method as recited in claim 1 wherein the index list has a first data size less than a second data size of the aggregated playlist.

11. A method as recited in claim 1 wherein forming an index list comprises forming a first sorting key and a second sorting key for first playlist content and further comprising sorting the index list using the first sorting key at the first aggregation client.

12. A method as recited in claim 11 further comprising sorting the index list using the second sorting key at the first aggregation client.

13. A method as recited in claim 12 wherein the first sorting key corresponds to alphabetical sort.

14. A method as recited in claim 12 wherein the second sorting key corresponds to a date sort.

15. A method as recited in claim 1 further comprising changing the first playlist of the first storage device to form an updated first playlist;

communicating the updated first playlist to the aggregation server;

forming an updated index list corresponding to the first playlist; and

communicating the index list to the first aggregation client.

16. A method as recited in claim 15 further comprising forming an update version corresponding to only the updated index list and communicating the update version to the first aggregation client.

17. A system comprising:

a first storage device having a first playlist comprising first playlist data corresponding to stored content;

a second storage device having a second playlist comprising second playlist data corresponding to stored content;

an aggregation server in communication with the first storage device and the second storage device receiving the first playlist and the second playlist, said aggregation server aggregating the first playlist data and the second playlist data to form an aggregated playlist having aggregated playlist data, forming an index list corresponding to the aggregated playlist; and

a first aggregation client in communication with the aggregation server receiving the index list from the aggregation server.

18. A system as recited in claim 17 wherein the first storage device and the aggregation server are each disposed within a first set top box.

19. A system as recited in claim 17 wherein the aggregation server is disposed within a first set top box and the first aggregation client is disposed within a second set top box.

20. A system as recited in claim 17 wherein the aggregation server is disposed within a computer and the first storage device is dispose within a set top box.

21. A system as recited in claim 17 wherein the first aggregation client sorts the index list.

22. A system as recited in claim 17 wherein the first aggregation client predicts indices from the index list that correspond to a visualization buffer.

23. A system as recited in claim 22 wherein the first aggregation client predicts indices larger than required for a screen display for the visualization buffer.

24. A system as recited in claim 22 wherein the first aggregation client requests playlist data from the aggregation server based on the indices corresponding to the visualization buffer.

25. A system as recited in claim 17 wherein the first aggregation client has a display associated therewith, said first aggregation client selecting a display entry and communicating indices corresponding to the selection to the aggregation server;

said aggregation server communicating at least one of the indices to the first storage device; and

said first storage device communicating content corresponding to the selection to the first aggregation client through a network.

26. A system as recited in claim 25 wherein the first storage device communicates content to the first aggregation client directly through a network.

27. A system as recited in claim 25 wherein the indices corresponding to the selection comprise a playlist holder identifier and a recording identifier.

28. A system as recited in claim 17 wherein the first aggregation client comprises a map for converting indices to a IP address for the first storage device.

29. A system as recited in claim 17 wherein the index list has a first data size less than a second data size for the aggregated playlist.

30. A system as recited in claim 17 wherein the index list comprises a first sorting key and a second sorting key and wherein the first aggregation client sorts the index list using the first sorting key at the first aggregation client.

31. A system as recited in claim 30 wherein the first sorting key corresponds to alphabetical sort.

32. A system as recited in claim 30 wherein the second sorting key corresponds to a date sort.

33. A system as recited in claim 17 wherein the first storage device changes the first playlist to form an updated first playlist and communicates the updated first playlist to the aggregation server;

said aggregation server forming an updated index list corresponding to the first playlist and communicating the index list to the first aggregation client.

34. A system as recited in claim 33 wherein the aggregation server forms an update version corresponding to only the updated index list and wherein the aggregation sever communicates the update version to the first aggregation client.
