A system and method for effectively protecting electronic content information includes a channel setup module that coordinates a channel setup procedure to create a secure communications channel between a content drive and a display module. A source DRM module transmits a special content key from the content drive to the display module over the secure communications channel. A content playback module then initiates a content playback procedure for utilizing the electronic content. The source DRM module responsively encrypts the electronic content with the content key. The channel setup module and the content playback module are unable to access or utilize the content key. A destination DRM module then receives the electronic content over the secure communications channel and utilizes the content key to decrypt the electronic content.
