Dynamic complexity prediction and regulation of MPEG2 decoding in a media processor

摘要

A method and system of regulating the computation load of an MPEG decoder in a video processing system are provided. The video processing system processes the header information of a compressed video data stream including a plurality of macroblocks with a motion vector associated therewith. Then, the computation load of each functional block of the MPEG decoder is adjusted according to predetermined criteria; thus, substantial computational overhead is desirably avoided.
