Bit stream analyzing method and apparatus

摘要

The present invention enables to enhance a processing performance in analyzing a bit stream of decoding a variable-length code to be successively processed.The present invention provides an MPEG video decoder for decoding an MPEG video stream including: a pre-purser 3 (bit stream divider) for detecting a slice start code of Slice layer and dividing a bit stream into two sub streams; video decoders 9 and 10 for decoding the sub streams separately from each other; a memory controller (memory interface) for combining with consistency the decoded data from the video decoders 9 and 10; and an external memory 4.
