View Patent ↗A content distribution system for transporting audio or video licenses between content players that use digital rights management (DRM) is disclosed. The content distribution system includes at least a second license repository and an authentication engine. The second license repository receives second information describing a second plurality of content licenses. A first license repository stores a first plurality of content licenses.
