PURPOSE: To perform operations with different kinds of formats and to decode main profile high level data by making access memory by using a parallel decoding pass. CONSTITUTION: The parallel decoding pass of an MPEG-2 decoder 110 is provided with VLDs 118, 122, inverse quantization processors 134, 138 and inverse discrete cosine transform processors 142, 146. A data stream generated by the decoding pass is processed by motion compensation processing circuits 158, 160 and 166, and a single timewisely multiplexed stream for the block of a decoded picture element is generated. The decoding pass reads/writes data on memory 120. Picture element data to express individual line of a decoded image is obtained for display by making access the memory 120 by using memory 174 and a display controller 175. |
