<p>An MPEG coded picture decoding apparatus includes a stream buffer memory (1) for storing an MPEG stream, a pack header processing section (3) for separating a pack header of the MPEG stream and extracting SCR information, a PES packet processing section (4) for separating a header of a PES stream, extracting PTS information and separating packets, a GOP detection section (5) for detecting a GOP of a video stream, a video buffer memory (6) for storing the video stream, a video MPEG decoding section (8) for MPEG decoding the video stream, a decoded data storage section (9) for storing and managing one picture frame, a video display processing section (10) for storing several picture frames and reading out at a display timing, and an error information processing section (14) for supervising a picture frame memory at each display timing and developing a video re-sending request when the picture frame memory is in an irregular condition. <IMAGE></p> |
