Abstract:
Content is stored as ClearText by a content provider within a trusted area. Specific content is requested by an end user, preferably via a service provider, and the requested content is encrypted and then delivered over a secure communications channel to a home server system. While the encrypted content is stored on the home server system, the associated encryption keys are stored as a license with the content provider. When a playback device on the home server system is instructed to play back the encrypted content, the encrypted content is streamed from local storage within the home server system while the associated encrypted keys are simultaneously streamed from the content provider to the playback device.
