摘要： In accordance with a specific aspect of the present invention, a compressed video stream, such as an MPEG-2 video stream, is received by a transport demultiplexor, synchronized, parsed into separate packet types, and written to buffer locations external the demultiplexor. Adaptation field is handled by a separate parser. In addition, primary elementary stream data can be handled by separate primary elementary stream parsers based upon the packet identifier of the primary elementary stream. Video packets can be parsed based upon stream identifier values. Specific packets of data are stored in one or more system memory or video memory buffers by an output controller based upon allocation table information. Private data associated with specific elementary streams or packet adaptation fields are repacketized, and written to an output buffer location. In specific implementations, the hardware associated with the system is used to acquire the data stream without any knowledge of the specific protocol of the stream. In another embodiment, the hardware is used to implement a splicing of streams of data.

摘要： In a specific embodiment of the present invention, a system and method is disclosed having a plurality of modes for providing and/or receiving compressed video data at a frame buffer memory. The modes include providing compressed video data directly from a system host system or through a direct memory access controller; or indirectly from a system host through a demultiplexer portion using one or more registers to receive and handle a transport stream. Another mode of operation includes receiving a transport stream containing compressed video data from a head end system. The compressed video data is subsequently processed through a demultiplexer portion.

摘要： A graphics processor receives a compressed encrypted video stream. The graphics processor decrypts the compressed encrypted video stream and stores a decrypted version (i.e., a decrypted compressed video stream) in a protected portion of an on-chip or off-chip video memory. The graphics processor then permits processors and other bus masters on the graphics processor to access the on-chip video memory, but conditionally limits access to other bus masters that are located off-chip, such as a central processing unit located off-chip and coupled to the graphics processor via a bus.
