ABSTRACT:
A video decoding apparatus comprises a demultiplexer which demultiplexes multi-bit streams to extract a coded bit stream, a decoder which decodes the coded bit stream, a sync signal detector which detects the sync information from the bit stream, and informs the decoder of the sync information, an error checker which checks an error based on output information of the decoder, and an important information construction device which constructs the important information from header information output from the decoder, and informs the decoder of the important information.
