The GDC21D301A Transport Decoder resides in the center of an MPEG-2 decoding system. It accepts MPEG-2 transport streams, parses the transport and packetized elementary stream (PES) layers into the separate data streams, and provides rate buffering for the parsed data streams. Then it passes those data streams to video and audio decoders. The GDC21D301A also extracts Program Clock Reference (PCR) in the data stream and provides the Pulse Width
Modulation (PWM) signals in order to recover the clock and to synchronize the playback of video and audio. The GDC21D301A manages an external DRAM that is used for data storage and buffering the various parsed data streams. This DRAM is shared with the host processor so that the system's memory requirements can be consolidated into a single, low-cost DRAM. The GDC21D301A stores data packets destined for the host directly in shared DRAM for easy access by the host.
