Abstract

An MPEG image decoding apparatus and method is disclosed, by which normal images can be supplied even if a bit stream is a nonstandardized bit stream having an error. The apparatus comprises a buffer for temporarily storing data of an input bit stream and outputting the stored data in input order; a register for storing the data output from the buffer in its empty area; a first data-search section for searching the data stored in the register so as to detect a specific code by executing a byte-unit collating operation; a second data-search section for searching the data so as to detect a specific code by executing a bit-unit collating operation; a control section for choosing one of outputs from the first and second data-search sections; a shifter for extracting a retrieved data from among the data stored in the register based on the chosen output, and shifting the remaining non-retrieved data towards the head of the register and making an empty area in the register; and a decoder for decoding the retrieved data.
