PROBLEM TO BE SOLVED: To provide a system which allows low delay coding being more effective in a parallel processing environment.SOLUTION: A slice, WPP substream, and a low byte sequence payload being coded by descripting an image in a tile are re-divided and cut into segments, with accompanied continuation of coding probability compatibility over an entire segment border. The segment border does not reduce entropy coding efficiency. A segment is smaller than an original slice, WPP substream, and tile, and faster than the slice that is not cut, WPP substream, and tile for transfer with short delay. A substream marker NAL unit, so that the transport demultiplexer can assign the data of slice to a corresponding substream, tile in the NAL unit, uses a multi-thread decoder in the NAL unit so that it functions in parallel with the corresponding substream and the tile.SELECTED DRAWING: Figure 3 |
