Partially parallel decoder for compressed hdtv video data

摘要

A decoder for variable-length-coded, motion-compensated data is given, where portions of data independently encoded using variable length coding are decoded in parallel using a plurality of variable length decoders (VLDs) (38-1). The fixed-length codes output by VLDs (38-1) are recombined by a commutator (42) to form a composite stream (44) of fixed-length-coded data. Motion compensator (14) operates on composite stream (44) to yield a decoded video stream.
