Abstract:
To manage playout of digital media by a media player, a wireless communication device (WCD) will include partitioned data storage including discrete partitions having distributor-modules corresponding with various media distributors, and including a digital rights management (DRM) controller. When the media player seeks to play media, it will request a DRM key from the WCD. The DRM controller may then identify the appropriate distributor-module and request the key from the distributor-module. If the distributor-module possesses the key, it will return it for transmission to the media player. Otherwise, the distributor-module may engage in secure communication with a provisioning system to obtain the DRM key and may then return the key. Upon receipt of the key, the media player may then play the media.
