Abstract

Methods and apparatus for managing devices and content in a network environment. In one implementation, a method of presenting content data includes: receiving at a client in a hub network a present request indicating locked content data; checking a license corresponding to said locked content data to determine if said license permits said client to present said locked content data; and presenting said locked content data through a presentation component connected to said client; wherein said license of said locked content data is bound to said hub network.

Claims

1. A method of presenting content data, comprising:

receiving at a client in a hub network a present request indicating locked content data;

checking a license corresponding to said locked content data to determine if said license permits said client to present said locked content data; and

presenting said locked content data through a presentation component connected to said client;

wherein said license of said locked content data is bound to said hub network.

2. The method of claim 1, wherein:

said locked content data and said license are stored on said client.

3. The method of claim 2, wherein:

presenting said locked content data includes decrypting said locked content data to produce output content data and sending said output content data to said presentation component.

4. The method of claim 1, wherein:

said locked content data is stored on a server, said server is connected to said client in said hub network.

5. The method of claim 1, wherein:

checking said license includes sending a confirm license request to said server from said client.

6. The method of claim 5, wherein:

presenting said locked content data includes receiving output content data streamed from said server to said client.

7. The method of claim 5, further comprising:

checking a revocation list to determine whether said client is included in said revocation list;

wherein said revocation list is stored on said server.

8. The method of claim 1, further comprising:

checking a revocation list to determine whether said client is included in said revocation list;

wherein said revocation list is stored on said client.

9. The method of claim 1, wherein:

said locked content data is media data.

10. The method of claim 1, wherein:

said presentation component is integral to said client.

11. The method of claim 1, wherein:

said presentation component is external to said client.

12. The method of claim 1, wherein:

said presentation component includes a television.

13. The method of claim 1, wherein:

said presentation component includes an audio speaker system.

14. A method of presenting content data, comprising:

receiving at a server in a hub network a present request indicating locked content data and a client in said hub network;

checking a license corresponding to said locked content data to determine if said license permits said server to present said locked content data through said client; and

presenting said locked content data by streaming data to said client;

wherein said license of said locked content data is bound to said hub network.

15. The method of claim 14, wherein:

streaming data to said client includes streaming locked content data to said client.

16. The method of claim 14, further comprising:

decrypting said locked content data.

17. The method of claim 14, wherein:

said present request is received from said client.

18. The method of claim 14, further comprising:

checking a revocation list to determine whether said client is included in said revocation list;

wherein said revocation list is stored on said server.

19. A method of copying content data, comprising:

receiving in a hub network a copy request indicating locked content data; and

copying said locked content data to produce a copy of said locked content data;

wherein said locked content data has a corresponding license that is bound to said hub network.

20. The method of claim 19, further comprising:

checking said license to determine if said license permits said locked content data to be copied.

21. The method of claim 19, further comprising:

requesting a new license from a server for said copy of said locked content data;

wherein said server is in said hub network and connected to said client.

22. The method of claim 19, further comprising:

sending said copy of said locked content data to a device that is not a member of said hub network.

23. The method of claim 19, further comprising:

sending said copy of said locked content data to a client that is a member of said hub network but is not connected to said hub network.

24. The method of claim 19, further comprising:

sending a new license to a client that is a member of said hub network but is not connected to said hub network.

25. The method of claim 19, further comprising:

checking a revocation list to determine whether said client is included in said revocation list;

wherein said revocation list is stored on said client.

26. A method of distributing content data, comprising:

receiving from a providing device in a hub network at a receiving device a copy of locked content data;

requesting a new license for said copy of locked content data; and

receiving said new license.

27. The method of claim 26, wherein:

said providing device is a client in said hub network.

28. The method of claim 26, wherein:

said providing device is a server in said hub network.

29. The method of claim 26, wherein:

said new license is received from said client.

30. The method of claim 26, wherein:

said new license is received from a server in said hub network.

31. The method of claim 26, wherein:

said new license is received from an external server that is not in said hub network.

32. The method of claim 26, wherein:

said copy of locked content data has corresponding licensing authority information stored on said device, and

said new license is received from a licensing authority indicated by said licensing authority information.

33. The method of claim 26, wherein:

said receiving device is not a member of said hub network.

34. The method of claim 26, wherein:

said receiving device is a member of a second hub network, and

said new license of said copy of locked content data is bound to said second hub network.

35. The method of claim 26, wherein:

said receiving device is not connected to said hub network.

36. The method of claim 26, further comprising:

checking a revocation list to determine whether said device is included in said revocation list;

wherein said revocation list is stored on said device.

37. A method of distributing content data, comprising:

receiving at a server in a hub network from a device a request for a new license for a copy of locked content data;

checking a root license stored on said server to determine if said root license permits said server to provide a new license for said copy of locked content data; and

creating said new license according to said root license;

sending said new license to said device.

38. The method of claim 37, wherein:
