Abstract

Media rights are managed to include not just device authentication, but to include elements of user, device, and service authorization. A user can play media on a mobile device, continue playing the media on a desktop computer, and subsequently move to a large screen television and media rights are automatically identified to provide the most appropriate authorized content. This allows an authorized user to seamlessly access different forms of the same content on a variety of authenticated devices using the same digital rights management mechanisms.

Claims

1. A system, comprising:

a fragment server configured to receive a request from a user to access a piece of media content at a first service level

a storage device configured to maintain a service level authorized for the user;

wherein the fragment server is configured to access the storage device to determine whether the user is authorized to receive media content at a first service level at a first device and whether the user is authorized to receive media content at a second service level at a second device.

2. The method of claim 1, wherein the media content transmitted to the first device comprises a media stream group of pictures (GOP), the GOP including a plurality of MPEG-4 fragments corresponding to a first quality level.

3. The method of claim 2, wherein the media content transmitted to the second device comprises a media stream group of pictures (GOP), the GOP including a plurality of MPEG-4 fragments corresponding to a second quality level.

4. The method of claim 1, wherein if the user is authorized to receive the media content at the second service level, the media content is transmitted to the second device.

5. The method of claim 4, wherein the media content is the same program.

6. The method of claim 4, wherein the position where playback is stopped at the first device is identified.

7. The method of claim 4, wherein the media content transmitted to the second device begins where playback is stopped at the first device.

8. The method of claim 1, wherein the first device is a mobile device.

9. The method of claim 8, wherein the second device is a set top box.

10. The method of claim 8, wherein the second device is associated with a television screen.

11. The method of claim 1, wherein if the user is not authorized to receive the media content at the second service level, a message is transmitted to the user.

12. A method, comprising:

identifying a user;

authorizing the user to access a piece of media content at a particular service level;

receiving a first request from a first device to receive the media content, the request associated with a first service level;

determining that the user is authorized to receive the media content at the first service level;

transmitting the media content to the first device;

receiving a second request from a second device to receive the media content, the request associated with a second service level;

determining whether the user is authorized to receive the media content at the second service level.

13. The method of claim 12, wherein the media content transmitted to the first device comprises a media stream group of pictures (GOP), the GOP including a plurality of MPEG-4 fragments corresponding to a first quality level.

14. The method of claim 13, wherein the media content transmitted to the second device comprises a media stream group of pictures (GOP), the GOP including a plurality of MPEG-4 fragments corresponding to a second quality level.

15. The method of claim 12, wherein if the user is authorized to receive the media content at the second service level, the media content is transmitted to the second device.

16. The method of claim 15, wherein the media content is the same program.

17. The method of claim 15, wherein the position where playback is stopped at the first device is identified.

18. The method of claim 15, wherein the media content transmitted to the second device begins where playback is stopped at the first device.

19. The method of claim 12, wherein the first device is a mobile device.

20. An apparatus, comprising:

means for identifying a user;

means for authorizing the user to access a piece of media content at a particular service level;

means for receiving a first request from a first device to receive the media content, the request associated with a first service level;

means for determining that the user is authorized to receive the media content at the first service level;

means for transmitting the media content to the first device;

means for receiving a second request from a second device to receive the media content, the request associated with a second service level;

means for determining whether the user is authorized to receive the media content at the second service level.
