Abstract

Methods, systems and computer program products to implement generic Digital Rights Management (DRM) are provided herein. The methods include opening a session between an initiator and a responder, exchanging one or more of device and system information and sending one of an operation or event based on DRM capabilities, DRM partner, DRM authority, DRM characteristics, DRM Trust and CCEVS profiles. The operation includes one or more of a dataset, response code, operation parameter and response parameter. These extensions may be in the form of one or more of an operation, an event, a dataset or property code.

10. The method of claim 9, wherein in response to the operation, the responder sends a dataset with a list of capabilities of multiple DRM systems deployed on the responder to the initiator.

11. The method of claim 10, wherein the list includes one or more of DRM system capability datasets.

12. The method of claim 11, wherein each of the DRM system capability datasets includes one or more of a DRM system identification, DRM capability vendor, DRM capability version, DRM capability features, DRM capability permissions and DRM capability status.

13. A method to exchange a information on devices that share a common Digital Rights Management (DRM) system between a first device and a second device operating under a data transfer protocol, comprising:

opening a session between the first device and the second device;

exchanging one or more of device and system information; and

sending or receiving one of an operation or event related to devices that share common a common DRM system;

wherein said operation and/or event includes one or more of a dataset, response code, operation parameter and response parameter.

14. The method of claim 13, wherein the devices are computational devices in a home or office network and share a common DRM system.

15. The method of claim 13, wherein the protocol is one of a Media Transport Protocol (MTP) or a Picture Transfer Protocol (PTP).

16. The method of claim 13, wherein the sending step further comprises sending an operation from the first device to the second device requesting characteristics of devices that share a common DRM system.

17. The method of claim 13, wherein in response to the operation, the second device sends a dataset including a list of devices that share a common DRM system to the first device.

18. The method of claim 17, wherein the dataset includes one or more of partner link type, partner link address, partner alias name, partner device type and partner sharing rights.

19. A method to exchange Digital Rights Management (DRM) authority characteristics between an initiator and a responder operating under a data transfer protocol, comprising:

opening a session between an initiator and a responder;

exchanging one or more of device and system information; and

sending or receiving one of an operation or event based on a DRM authority that manages a plurality of computational devices;

wherein said operation and/or event includes one or more of a dataset, response code, operation parameter and response parameter.

20. The method of claim 19, wherein the protocol is one of a Media Transport Protocol (MTP) or a Picture Transfer Protocol (PTP).

21. The method of claim 19, wherein the sending step further comprises sending an operation from the initiator to the responder requesting data on a DRM authority that manages a plurality of computational devices.
