Abstract

A digital rights management (DRM) method and apparatus are provided. The DRM method includes transmitting a rights object request message; receiving a rights object response message based on a Universal Plug and Play (UPnP) contents directory service; and acquiring a rights object using the rights object response message. Another DRM method includes receiving a rights object request message; and transmitting a rights object response message based on a Universal Plug and Play (UPnP) contents directory service. The DRM apparatus includes a transmitting unit which transmits a rights object request message to a media server of a DRM domain; a receiving unit which receives a rights object response message based on a Universal Plug and Play (UPnP) contents directory service from the media server; and a playback unit which plays back a contents object on a basis of a rights object acquired using the rights object response message.

Claims

1. A digital rights management (DRM) method comprising:

transmitting a rights object request message;

receiving a rights object response message based on a Universal Plug and Play (UPnP) contents directory service; and

acquiring a rights object using the rights object response message.

2. The DRM method of claim 1, wherein the rights object response message includes the rights object or a uniform resource identifier (URI) of the rights object.

3. The DRM method of claim 1, wherein the rights object request message includes at least one of a contents identifier (ID) of contents corresponding to the rights object, a rights object ID of the rights object, and an object ID based on the UPnP contents directory service allocated to the rights object.

4. The DRM method of claim 1, wherein the rights object request message is generated using an action based on the UPnP contents directory service.

5. The DRM method of claim 4, wherein the action is a browse action or a search action.

6. The DRM method of claim 4, wherein the action includes at least one of an identifier (ID) argument representing a rights object ID or a contents ID, an ID type argument indicating which of the rights object ID and the contents ID the ID argument represents, and a DRM type argument for identifying a DRM standard of a requested rights object.

7. A digital rights management (DRM) method comprising:

receiving a rights object request message; and

transmitting a rights object response message based on a Universal Plug and Play (UPnP) contents directory service.

8. The DRM method of claim 7, wherein the rights object response message includes a rights object or a uniform resource identifier (URI) of the rights object.

9. The DRM method of claim 7, wherein the rights object response message is generated using an action based on the UPnP contents directory service.

10. The DRM method of claim 9, wherein the action is a browse action or a search action.

11. The DRM method of claim 9, wherein an attribute of a <

res>

property in the action represents a rights object or a uniform resource identifier (URI) of the rights object.

12. The DRM method of claim 7, wherein the rights object response message corresponds to a rights object and includes a rights object representing object having a uniform resource identifier (URI) of the rights object, and the rights object representing object is an object based on the UPnP contents directory service.

13. A digital rights management (DRM) apparatus comprising:

a transmitting unit which transmits a rights object request message to a media server of a DRM domain;

a receiving unit which receives a rights object response message based on a Universal Plug and Play (UPnP) contents directory service from the media server; and

a playback unit which plays back a contents object on a basis of a rights object acquired using the rights object response message.

14. The DRM apparatus of claim 13, wherein the rights object response message includes the rights object or a uniform resource identifier (URI) of the rights object.

15. The DRM apparatus of claim 13, wherein the rights object request message includes at least one of a contents identifier (ID) of contents corresponding to the rights object, a rights object ID of the rights object, and an object ID based on the UPnP contents directory service allocated to the rights object.

16. The DRM apparatus of claim 13, wherein the rights object request message is generated using an action based on based on the UPnP contents directory service.

17. The DRM apparatus of claim 16, wherein the action is a browse action or a search action.

18. The DRM apparatus of claim 16, wherein the action includes at least one of an identifier (ID) argument representing a rights object ID or a contents ID, an ID type argument indicating which of the rights object ID and the contents ID the ID argument represents, and a DRM type argument for identifying a DRM standard of a requested rights object.

19. A digital rights management (DRM) apparatus comprising:

a receiving unit which receives a rights object request message from a media renderer of a DRM domain; and

a transmitting unit which transmits a rights object response message based on a Universal Plug and Play (UPnP) contents directory service to the media renderer.

20. The DRM apparatus of claim 19, wherein the rights object response message includes a rights object or a uniform resource identifier (URI) of the rights object.

21. The DRM apparatus of claim 19, wherein the rights object response message is generated using an action based on the UPnP contents directory service.

22. The DRM apparatus of claim 21, wherein the action is a browse action or a search action.

23. The DRM apparatus of claim 21, wherein an attribute of a <

res>

property in the action represents a rights object or a uniform resource identifier (URI) of the rights object.

24. The DRM apparatus of claim 19, wherein the rights object response message corresponds to a rights object and comprises a rights object representing object having a uniform resource identifier (URI) of the rights object, and the rights object representing object is an object based on the UPnP contents directory service.

25. A digital rights management (DRM) method comprising:

if a media server exists in a DRM domain, acquiring a rights object from the media server; and

if the media server does not exist in the DRM domain, acquiring a rights object from a rights object issuing server,

wherein the acquiring of the rights object from the media server comprises;

transmitting a rights object request message to the media server;

receiving a rights object response message based on a Universal Plug and Play (UPnP) contents directory service from the media server; and

acquiring the rights object using the rights object response message.
