A content server is provided for storing and distributing digital content to a client. The content server includes a content database configured to electronically store the digital content and a DRM packager for adding a universal DRM layer to the digital content stored at the content database. The universal DRM layer is able to access digital content in conformance with a plurality of different DRM implementations, the digital content being in conformance with one of the plurality of different DRM implementations. The universal DRM layer can access the content by a variety of means, such as with a universal key, for example, that can decrypt content from many different DRM technologies. In this way the client only needs to have a DRM controller that is compatible with this higher-level, universal DRM implementation rather than with the individual, underlying DRM implementations. |
