    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.

    Abstract: Techniques for maintaining an order of transactions in a multi-bus computer architecture. In an embodiment, an arbitrator receives access requests from a plurality of requestors, each access request requesting a respective access to a bus. Based on an arbitration between the access requests - e.g. between those requestors providing the access requests - the arbitrator may generate a grant message which triggers a carrying of a first message on the first bus. In certain embodiments, the grant message further triggers another carrying of the first message on the second bus.

    Abstract: Encoded data decoding techniques. A data decoding agent determines a data segment size for a packet that includes a header and a data segment. The data decoding agent determines a segment end location based, at least in part, on the data segment size. The data decoding agent processes subblocks of data from the data segment. The data decoding agent compares a current location to the segment end location to determine if a current subblock of data from the data segments contains the segment end location. The data decoding agent triggers an exception handler if the current subblock contains the segment end location.
