Abstract

A method of managing a right to use digital content and user equipment thereof are disclosed. In digital rights management (DRM), the usable period of a right to use content may be updated in case that a user wishes to extend the deadline to use the content of which usable right has expired.

Claims

1. A user equipment for use in managing a right to use content, comprising:

first means for requesting a condition to use the content to a server;

second means for receiving condition data as a response to the request of the first means from the server; and

third means for updating the condition to use the content using the condition data.

2. The user equipment of claim 1, wherein the first means transmits authentication information of the user equipment to the server.

3. The user equipment of claim 1, wherein the first means transmits identification information of the content to the server.

4. The user equipment of claim 1, wherein the condition data includes a deadline to use the content.

5. The user equipment of claim 1, wherein the condition data includes a usable count of the content.

6. The user equipment of claim 1, wherein the condition data includes a usable period of the content.

7. The user equipment of claim 1, wherein the condition data includes a usable cumulative time of the content.

8. A user equipment in managing a right to use previously-stored content, comprising:

first means for requesting an update of an expiration period for the usable right of the content to the server;

second means for downloading data necessary for the update of the expiration period from the server; and

third means for updating the expiration period previously set in the content using the downloaded data.

9. The user equipment of claim 8, further comprising a fourth means for receiving a message notifying a period expiration for the right to use the content, and for outputting information of the received message.

10. The user equipment of claim 9, wherein the fourth means receives a message notifying a period of expiration is approaching for the right to use the content and outputs information of the received message.

11. The user equipment of claim 8, wherein the second means transmits at least one of authentication information of the user equipment and identification information of the content to the server and wherein the authentication information and the identification information are needed to request the update of the expiration period.

12. The user equipment of claim 11, wherein if a user requests a specific expiration period, the second means further transmits the user-requesting expiration period to the server.

13. The user equipment of claim 8, wherein the expiration period is either a usable count of the content or a usable period of the content.

14. The user equipment of claim 8, wherein the expiration period is a count enabling a use of the content within a prescribed period.

15. The user equipment of claim 8, wherein the expiration period is a cumulative value of usable time of the content.

16. A method of managing a right to use content in a user equipment, comprising:

requesting by the user equipment to update at least one condition of the right to use content to a server;

receiving from the server condition data in response to the request by the user equipment; and

updating the at least one condition of the right to use content using the condition data.

17. The method of claim 16, wherein in requesting the condition to use the content, authentication information of the user equipment is transmitted to the server.

18. The method of claim 16, wherein in requesting to update at least one condition of the right to use content, identification information of the content is transmitted to the server.

19. The method of claim 16, wherein the condition data includes a deadline to use the content.

20. The method of claim 16, wherein the condition data includes a usable count of the content.

21. The method of claim 16, wherein the condition data includes a usable period of the content.

22. The method of claim 16, wherein the condition data includes a usable cumulative time of the content.

23. The method of claim 16, wherein the condition data includes a usable user range of the content.

24. The method of claim 16, wherein the condition data includes a usable user equipment range of the content.

25. A method of managing a right to use content downloaded to a user equipment, comprising:

requesting an update of an expiration period for the right to use the content to a server;

downloading data necessary to update the expiration period from the server; and

updating the expiration period previously set in the right to use the content using the downloaded data.

26. The method of claim 25, further comprising:

notifying the user equipment that the right to use has expired from the server, if the period for the right to use the content expires.

27. The method of claim 25, further comprising:

notifying the user equipment before an expiration period of the right to use the content that expiration of the right to use is approaching from the server.

28. The method of claim 25, wherein in requesting the update of the expiration period, authentication information of the user equipment is transmitted to the server.

29. The method of claim 25, wherein in requesting the update of the expiration period, identification information of the content is transmitted to the server.

30. The method of claim 25, wherein in requesting the update of the expiration period, a user-specific expiration period is transmitted to the server.

31. The method of claim 25, wherein in updating the expiration period, the user equipment changes the expiration period into a new expiration period with reference to the data.

32. The method of claim 25, wherein the expiration period is either a usable count of the content or a usable period of the content.

33. The method of claim 25, wherein the expiration period is a count enabling a use of the content within a prescribed period.

34. The method of claim 25, wherein the expiration period is a cumulative value of usable time of the content.

35. A method of managing a right to use content in a user equipment, comprising:

transmitting stored right to use information including a time condition to a server;

receiving updated right to use information including a new time condition from the server; and

updating the stored right to use information.

36. The method of claim 35, wherein updating the stored right to use information replaces the stored right to use information with the new right to use information.

37. The method of claim 35, wherein the stored right to use information includes authentication information of the user equipment.

38. The method of claim 35, wherein the stored right to use information includes identification information of the content.

39. The method of claim 35, wherein the stored right to use information includes a user-specific period condition.

40. The method of claim 35, wherein the stored right to use information includes either a usable count of the content or a usable period of the content.

41. The method of claim 35, wherein the stored right to use information includes a count enabling a use of the content within a prescribed period.

42. The method of claim 35, wherein the stored right to use information includes a cumulative value of usable time of the content.
