The MPEG coded picture decoding apparatus includes a stream buffer memory for storing an MPEG stream, a pack header processing section for separating a pack header of the MPEG stream and extracting SCR information, a PES packet processing section for separating a header of a PES stream, extracting PTS information and separating packets, a GOP detection section for detecting a GOP of a video stream, a video buffer memory for storing the video stream, a video MPEG decoding section for MPEG decoding the video stream, a decoded data storage section for storing and managing one picture frame, a video display processing section for storing several picture frames and reading out at a display timing, and an error information processing section 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.Other References
