Abstract:
Methods and systems of rendering content on a device having a native digital rights management (DRM) system are described. A device, such as an end-user device capable of executing or playing content, acquires content in a common content format file having standardized locations for specific types of data. A generic digital rights token associated with the content is obtained by utilizing one of the standardized locations in the content format file, where the rights token contains information sufficient to allow retrieval of the rights associated with the content. Utilizing data in another of the standardized locations, it is then determined whether the device is registered in a domain. A license server directory may be accessed utilizing data in another of the standardized locations in the common content format file and a domain identifier, a device identifier, or both are transmitted to the license server directory. A native DRM system trigger is received and, upon activation of the trigger, a native DRM license is acquired, thereby enabling rendering of the content in the common content format file on the device.
