Universal DRM support for devices
摘要:
Embodiments of the present invention allow a system or client device to process multiple Digital Rights Management (DRM) systems and formats using a universal DRM client. The universal DRM client can operate based on a universal license so that it may use the same DRM scheme or format used by the content provider. A DRM system may then build a universal license that includes information for gaining access to the content in the DRM package. In turn, a DRM package and the universal license may be provided to the universal client. Based on the information in the universal license, the client device can access the protected content even if it does not have the specific client program code for the DRM format used originally by the content provider.
