Video decoding apparatus and method based on multiprocessor

A multiprocessor-based video decoding method using a stream parser and a plurality of processors, the method comprising:

• a preprocessing and parsing operation of dividing, by the stream parser, an input stream by row and parsing a skip counter and a quantization parameter of the input stream;
• an acquiring operation of acquiring, by the plurality of processors, the plurality of divided streams, the skip counter and the quantization parameter generated by the stream parser and acquiring decoded information of an upper processor among neighboring processors by row;
• and
• a parallel-decoding operation of parallel-decoding, by the plurality of processors, the plurality of divided streams by row by using the information acquired by the plurality of processors in the acquiring operation.
