Abstract
Conditional access (CA) and digital rights management (DRM) in digital media delivery, processing, and storage systems. Methods and apparatuses are provided for managing digital rights under the protection of multiple CA and/or DRM systems. Some embodiments provide secure and robust methods for bridging multiple DRM systems in the digital media content distribution and playback systems. The present invention simplifies content repurposing, after it has been bridged to a secondary DRM system, but still under the control of the original DRM system.
