Abstract

A rendering system adapted for use in a system for managing use of content and operative to rendering content in accordance with usage rights associated with the content. The system includes a rendering device configured to render the content and a repository coupled to the rendering device and operative to enforce usage rights associated with the content and permit the rendering device to render the content in accordance with a manner of use specified by the usage rights.

Claims

1. A rendering system adapted for use in a system for managing use of content, said rendering system being operative to rendering content in accordance with usage rights associated with the content, said rendering system comprising:

a rendering device configured to render the content; and

a repository coupled to said rendering device and operative to enforce usage rights associated with the content and permit the rendering device to render the content in accordance with a manner of use specified by the usage rights.

2. A rendering system as recited in claim 1, wherein said rendering device is configured to render content into a desired form.

3. A rendering system as recited in claim 1, wherein said repository is operative to receive a request to render the content and permit the content to be rendered only if a manner of use specified in the request corresponds to a manner of use specified in the usage rights.

4. A rendering system as recited in claim 3, wherein said repository comprises means for storing the content.

5. A rending system as recited in claim 1, further comprising means for storing the content.

6. A rendering system as recited in claim 4 wherein said means for storing is means for storing ephemeral copies of the content.

7. A rendering system as recited in claims 4 wherein said means for storing comprises means for storing content after rendering.

8. A rendering system as recited in claim 7 wherein the content comprises fonts.

9. A rendering system as recited in claim 7 wherein the content comprises music.

10. A rendering system as recited in claim 7 wherein the content comprises video.

11. A rendering system as recited in claim 1 wherein said rendering device comprises a printer.

12. A rendering system as recited in claim 1, wherein said rendering device comprises a video system.

13. A rendering system as recited in claim 1, wherein said rendering device comprises an audio system.

14. A rendering system as recited in claim 1 wherein said rendering device comprises a computer system and said repository comprises software executed on the computer system.

15. A rendering system as recited in claim 1, further comprising an execution device coupled to said repository, said repository being further operative to permit said execution device to execute a computer program only in a manner specified by the usage rights.

16. A rendering system as recited in claim 1, wherein the content is a computer program and the manner of use is a manner of executing the computer program.

17. A rendering system as recited in claim 1, wherein the manner of use is a manner of printing.

18. A rendering system as recited in claim 1, wherein the manner of use is a manner of displaying.

19. A rendering system as recited in claim 1, wherein the manner of use is a manner of playing.

20. A rendering system as recited in claim 1, wherein the rendering device and the repository are integrated into a secure system having a secure boundary.

21. A rendering system as recited in claim 1, wherein the rendering device and the repository are separate devices.

22. A rendering system as recited in claim 1, wherein the usage rights include at least one condition that must be satisfied to exercise the manner of use, and wherein the system further comprises means for communicating with an authorization repository for authorizing a condition.

23. A rendering system as recited in claim 1, further comprising means for communicating with a master repository for obtaining an identification certificate for the repository.

24. A rendering system as recited in claim 1, further comprising a boundary containing said repository and said rendering device in a secure environment.

25. A rendering system as recited in claim 22, wherein the condition is possession of a digital ticket.

26. A rending system as recited in claim 1, wherein the content has plural components having usage rights associated therewith and wherein said repository enforces the usage rights for each component.

27. A rendering system as recited in claim 4, wherein said repository comprises removable media.

28. A rendering system as recited in claim 5, wherein said means for storing comprises removable media.
