Abstract

PURPOSE:To improve the processing capacity for entropy decoding by detecting a specific word from data of every entropy processing unit, writing the data in each different storage means at every processing unit, and executing in parallel the entropy decoding processing. CONSTITUTION:A unique word detecting part 91 detects a unique word and outputs a data switching control signal. A data switching part 92 discriminates data of one frame corresponding to one picture by a data switching control signal and adds a number in order of the arrival time, and writes it successively in idle memories 50-1-50-n. Subsequently, the data which have been written in the memories 50-1-50-n are read out in entropy decoding parts 60-1-60-n, and a decoding processing of every processing unit of each entropy is executed. In such a way, by providing the entropy decoding parts in parallel and executing the parallel processing, the processing capacity can be improved.
