摘要：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 apack header of the MPEG stream and extracting SCR information, a PES packet processingsection (4) for separating a header of a PES stream, extracting PTS information andseparating packets, a GOP detection section (5) for detecting a GOP of a video stream, avideo 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 andmanaging one picture frame, a video display processing section (10) for storing severalpicture frames and reading out at a display timing, and an error information processingsection (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 irregularcondition.
