ABSTRACT:
An apparatus and method of decoding coded video bitstreams is disclosed. The apparatus comprises a first processor and a second processor configured to operate in parallel. The main processor receives the coded video bitstream, parses it, and calls the second processor to decode the coded video bitstream to retrieve macroblock data. If an error occurs during decoding, the second processor signals the first processor, which can instruct the second processor to perform an error recovery routine. The first processor the performs dequantization and inverse DCT to recover digital pixel data from the macroblocks so that an image formed from the digital pixel data can be later displayed on a monitor.
