Abstract

The present invention is to efficiently perform parallel processing of data without increasing the amount of buffer required for data parallel processing in an image decoder. For this purpose, a frame of an image signal encoded by an image encoder is encoded. In a data parallel processing apparatus of a video decoder for parallel processing by bit strings, the coded bit strings of the parallel frame are grouped in a local unit, and the data grouped in the local unit is buffered into a plurality of modules. By distributing means for switching to transfer, it is possible to reduce the capacity increase of the buffer required for data parallel processing in the image decoder, while efficiently converting the image data signal into the coded bit stream without generating the buffer pool or empty phenomenon. Can be processed in parallel.
