Abstract

Device, system, and method of digital-rights-management (DRM). In some embodiments, a device may include a DRM agent to manage the utilizing of a content object including secured digital content based on a rights object related to the content object, wherein based on at least one restriction defined in the rights object, the agent is to cause the device to present supplemental content of at least one supplemental content object when the content object is utilized. Other embodiments are described and claimed.

Claims

1. An apparatus comprising:

a digital-rights-management agent to manage the utilizing of a content object including secured digital content based on a rights object related to said content object, wherein based on at least one restriction defined in said rights object, said agent is to cause said apparatus to present supplemental content of at least one supplemental content object when said content object is utilized.

2. The apparatus of claim 1, wherein said restriction relates to at least one group object including at least one reference to said at least one supplemental content object, respectively, and wherein said reference includes identification information to identify said supplemental content object.

3. The apparatus of claim 2, wherein said reference includes one or more presentation conditions restricting the presentation of said supplemental content, and wherein said agent is to cause said apparatus to selectively present said supplemental content based on said presentation conditions.

4. The apparatus of claim 3, wherein said presentation conditions comprise at least one of a timing condition defining one or more allowed time periods to present said supplemental content, and a count condition defining an allowed number of presenting said supplemental content.

5. The apparatus of claim 2, wherein said reference includes location information identifying a location of said supplemental content object, and wherein said agent is to obtain said supplemental content object based on said location information.

6. The apparatus of claim 5, wherein said reference includes expiration information indicating one or more expiration states of said supplemental content object.

7. The apparatus of claim 2, wherein said group object includes expiration information of a current group object stored by said apparatus and location information identifying a location of an up-to-date version of said group object, and wherein said agent is to replace said current version with said up-to-date version based on said expiration information.

8. The apparatus of claim 1, wherein said supplemental content object comprises presentation timing information, and wherein said agent is to control a timing of the presentation of said supplemental content based on said presentation timing information.

9. The apparatus of claim 1, wherein said supplemental content object is separate from said content object.

10. The apparatus of claim 1, wherein said agent is capable of obtaining said supplemental content object prior to allowing the utilizing of said content object.

11. The apparatus of claim 1, wherein said agent is to allow utilizing of said content object using said restriction only with the presentation of said supplemental content.

12. The apparatus of claim 1, wherein said content object comprises media content to be played back by a player application, and wherein said agent is to cause said player application to play back said supplemental content when playing said media content.

13. The apparatus of claim 1, wherein said supplemental content comprises advertisement content.

14. A digital-rights-management (DRM) system comprising:

a DRM server to generate a rights object restricting the utilizing of a content object including secured digital content, wherein said rights object includes at least one restriction to cause the presentation of supplemental content of at least one supplemental content object when utilizing said content object.

15. The system of claim 14, wherein said restriction relates to at least one group object including at least one reference to said at least one supplemental content object, respectively, and wherein said reference includes identification information to identify said supplemental content object.

16. The system of claim 15, wherein said restriction includes group object identification information to identify said group object, and integrity verification information to verify the integrity of said group object.

17. The system of claim 14 comprising a device including a digital-rights-management agent to manage the utilizing of said content object based on said rights object, wherein based on said restriction said agent is to cause said device to present said supplemental content when said content object is utilized.

18. The system of claim 14, wherein said supplemental content object is separate from said content object.

19. The system of claim 14, wherein said supplemental content comprises advertisement content.

20. A method of utilizing a content object including secured digital content, the method comprising:

receiving a rights object related to said content object; and

based on at least one restriction in said rights object, causing the presentation of supplemental content of at least one supplemental content object when said content object is utilized.

21. The method of claim 20, wherein said restriction relates to at least one group object including at least one reference to said at least one supplemental content object, respectively, and wherein said reference includes identification information to identify said supplemental content object.

22. The method of claim 21, wherein said reference includes one or more presentation conditions restricting the presentation of said supplemental content, and wherein causing the presentation of said supplemental content comprises selectively causing the presentation of said supplemental content based on said presentation conditions.

23. The method of claim 21, wherein said reference includes location information identifying a location of said supplemental content object, and wherein the method comprises obtaining said supplemental content object based on said location information.

24. The method of claim 21, wherein said group object includes expiration information of a current group object stored by said apparatus and location information identifying a location of an up-to-date version of said group object, and wherein the method comprises replacing said current version with said up-to-date version based on said expiration information.

25. The method of claim 20, wherein said supplemental content object is separate from said content object.

26. The method of claim 20 comprising obtaining said supplemental content object prior to allowing the utilizing of said content object.

27. The method of claim 20 comprising allowing the utilizing of said content object using said restriction only with the presentation of said supplemental content.

28. The method of claim 20, wherein said supplemental content comprises advertisement content.
