Abstract:
1. An H.264 decoder equipped with a plurality of operation units, the H.264 decoder comprising: a header decoding unit for decoding a Network Adaptation Layer (NAL) header and slice header data of received compressed image data; a memory unit for storing the decoded compressed image data and synchronization information related to each macroblock included in the compressed image data; each of the plurality of operation units: a macroblock assigning unit determining numbers of macroblocks for which the plurality of operation units perform operations and providing the numbers of macroblocks to respective ones of the operation units; and a decoding image output unit for outputting results of the operations as decoded image data related to the compressed image data when the third decoding operation of all the macroblocks included in the compressed image data is completed.
