Abstract
The present invention may be utilized for the distribution of content items protected according to various digital rights management platforms. According to one embodiment, a method for the propagation of DRM protected content to one or more devices connected to a network comprises generating a request for DRM protected content from a requesting device and streaming the requested DRM protected content from a content source as a protected DRM stream. The protected DRM stream is re-encrypted for streaming to the requesting device. The re-encrypted protected DRM stream is decrypted for playback on the requesting device.
