摘要： In general, in one aspect, a decode order for a group of picture (GOP) frame structure for a video stream is modified to include regenerated P frames. The modified decode order includes a regenerated P frame of a P frame decoded prior to a sequence of B frames after last B frame in the sequence of B frames and before next I or P frame. The frames are decoded in modified decode order by a decode engine. The decoded frames are post processed in a display order (only includes regenerated P frames and does not include initial P frames defined in the decode order) by a post processing engine. The post processing engine may ignore the initial P frames or the decode engine may not forward the initial P frames to the post processing engine. The post processed frames may be prepared for presentation by a display engine.

摘要： 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.
