Abstract

An apparatus for secured playback is presented. In one embodiment, the apparatus includes a controller that includes a key derivation module to manage authentication and key derivation. In one embodiment, the apparatus provides a video decryption key to a graphics engine if video data portions in a data stream are retrievable without having to decrypt the data stream. In one embodiment, the apparatus also includes a decryption module to decrypt a part of data in conjunction with an encryption key to generate video information and video data. The controller then writes an encrypted version of the video data to a video buffer of a graphics engine.
