Method for importing digital rights management data for user domain

1. A method for importing digital rights management (DRM) data, comprising:

registering a local rights manager (LRM) with a domain authority (DA);

exchanging, between the LRM and the DA, user domain information comprising meta information, wherein the meta information is used to acquire for acquiring DRM data for a user domain from non-Open Mobile Alliance (OMA) DRM data;

creating, by the LRM, a DRM content format (DCF) from the non-OMA DRM data based on the user domain information, the DCF conforming to an OMA DRM standard;

exchanging, between the LRM and a rights issuer (RI), the user domain information and a key used in creating the DCF; and

receiving, at the LRM from the RI, a rights object (RO) based on the user domain information, the RO conforming to the OMA DRM standard.

2. The method of claim 1 , wherein exchanging the user domain information comprises exchanging the meta information for acquiring DRM data for a user domain from the non-OMA DRM data.

3. The method of claim 1 , wherein registering comprises:

transferring LRM information to the DA;

transferring DA information to the LRM;

creating registration information based on the DA information, and transferring the registration information to the DA; and

registering the LRM based on the registration information, and transferring a registration result to the LRM.

4. A method for using digital rights management (DRM) data, comprising:

registering a local rights manager (LRM) with a domain authority (DA);

exchanging user domain information comprising a first key to create a rights object (RO);

creating, by the LRM, a DRM content format (DCF) from non-Open Mobile Alliance (OMA) DRM data based on the user domain information, the DCF conforming to an OMA DRM standard;

exchanging, between the LRM and a rights issuer (RI), a second key used in creating the DCF;

creating an RO for a user domain by the RI using the first key; and

transferring the DCF from the LRM to a DRM agent of a device.

5. The method of claim 4 , further comprising:

acquiring the RO for the user domain by the DRM agent.

6. The method of claim 5 , wherein the DRM agent acquires the RO from one of the group consisting of the LRM and the RI.

7. The method of claim 4 , further comprising:

transferring the RO from the RI to the LRM.

8. The method of claim 4 , wherein registering comprises:

transferring LRM information to the DA;

transferring DA information to the LRM;

creating registration information based on the DA information, and transferring the registration information to the DA; and

registering the LRM based on the registration information, and transferring a registration result to the LRM.

9. The method of claim 4 , further comprising:

sending a join domain request message from the DRM agent to join the DRM agent in the user domain.

10. A method for importing digital rights management (DRM) data, comprising:

registering a local rights manager (LRM) with a rights issuer (RI);

exchanging, between the LRM and the RI, user domain information comprising meta information for acquiring DRM data for a user domain from non-Open Mobile Alliance (OMA) DRM data;

creating, by the LRM, a DRM content format (DCF) from the non-OMADRM data based on the user domain information, the DCF conforming to an OMA DRM standard;

exchanging, between the LRM and the RI, a key used in creating the DCF; and

receiving, at the LRM from the RI, a rights object (RO) based on the user domain information, the RO conforming to the OMA DRM standard.

11. The method of claim 10 , wherein exchanging the user domain information comprises exchanging the meta information for acquiring DRM data for a user domain from the non-OMA DRM data.

12. The method of claim 10 , wherein registering comprises:

transferring LRM information to the RI;

transferring RI information to the LRM;

creating registration information based on the RI information, and transferring the registration information to the RI; and

registering the LRM based on the registration information, and transferring a registration result to the LRM.

13. A method for using digital rights management (DRM) data, comprising:

registering a local rights manager (LRM) with a rights issuer (RI);

exchanging user domain information comprising meta information for acquiring DRM data for a user domain from non-Open Mobile Alliance (OMA) DRM data;

creating, by the LRM, a DRM content format (DCF) from the non-OMA DRM data based on the user domain information, the DCF conforming to OMA DRM standard;

exchanging, between the LRM and the RI, a key used in creating the DCF;

creating, by the RI, a rights object (RO) for a user domain;

exchanging the user domain information between a domain authority (DA) and the RI; and

transferring the DCF from the LRM to a DRM agent of a device.

14. The method of claim 13 , wherein exchanging user domain information between the DA and the RI comprises exchanging the meta information for acquiring DRM data for the user domain from the non-OMA DRM data.

15. The method of claim 13 , further comprising:

acquiring the RO for the user domain by the DRM agent.

16. The method of claim 15 , wherein the DRM agent acquires the RO from one of the group consisting of the RI and the LRM.

17. The method of claim 13 , further comprising:

transferring the RO from the RI to the LRM.

18. The method of claim 13 , wherein registering comprises:

transferring LRM information to the RI;

transferring RI information to the LRM;

creating registration information based on the RI information, and transferring the registration information to the RI; and

registering the LRM based on the registration information, and transferring a registration result to the LRM.

19. The method of claim 13 , further comprising:

sending a join domain request message from the DRM agent to join the DRM agent in the user domain.
