<p>An MPEG decoder is provided which is capable of performing processing of all PTS/DTS values even if data with the PTS/DTS values added is contained consecutively in a system stream. The MPEG decoder is adapted to replace a start code ID of data with the PTS/DTS values added in a video elementary stream with a unused start code ID of a video layer and which includes a system decoder used to hold the PTS/DTS values and the unused start code ID value, a memory controller used to store the video elementary stream into a memory, to read and to output it and a video decoder used to detect the fact that the start code ID has the unused start code ID at the time of starting to decode the video elementary stream and to issue an instruction of interruption to occur to a processing device and to output images obtained from the decoding in accordance with the instruction from the processing device based on the interruption.</p> |
