A reference picture buffer may supply an asymmetric macroblock to a video encoder to improve the bandwidth between the encoder and buffer. The macroblock width may be sized to match the minimum burst width of the buffer. The size of the macroblock may be kept unchanged by reducing the macroblock height.

Reformatting data to decrease bandwidth between a video encoder and a buffer

Techniques for improved decryption of an encrypted media stream are described. In one embodiment, a system may include a receiver to receive an encrypted media stream, an extraction module to extract an encryption characteristic of the encrypted media stream, a first processor to produce configuration commands from the extracted encryption characteristic, a second processor to receive the encrypted media stream and the configuration commands, and to produce decrypted media based upon a decryption scheme indicated by the configuration commands, and a key distribution module, to distribute a decryption key to the second processor.

Techniques for secure provisioning of a digital content protection scheme

Techniques are described that can be used to store macroblocks to memory and retrieve macroblocks from memory. In some cases, macroblocks can be stored in memory in memory addressable locations with column and row addresses flipped. Because macroblocks are stored in columns but retrieved across rows, portions of multiple macroblocks can be retrieved in a single read burst. The portions can be Golomb decoded and stored so that macroblocks can be re-assembled from the portions. In some cases, macroblocks of encoded video can be stored in continuous memory addressable locations.
