An efficient system and process is utilized to achieve encoding, decoding and transcoding of audio/visual signals, as desired within an audio/visual processing system. The system coordinates the operations of several optimum components to achieve the necessary encoding/decoding/transcoding operations. Most significantly, the coordinated use of both a parallel processor and a bitstream processor, along with most effective interface techniques, are utilized to most efficiently carry out processing operations. The bitstream processor generally carries out those operations which include timing and sequence information, while the parallel processor is available to perform processing steps which are most efficiently carried out in parallel. Such processing steps include the actual compression/decompression of video signals. When combined with a system controller to orchestrate operations, along with memory and related interface components, a system and method to efficiently encode, decode or transcode A/V data is achieved.
