Abstract
Moving picture signal transmission system, wherein the data-compression is effected for the moving picture by the intraframe-encoding and the interframe-encoding, the signal is divided into the fixed frame-length transmission frame, the transmission frame has the header (A, B, C) which identifies whether it is the first transmission frame, the middle transmission frame or the last transmission frame in one picture frame signal, and then the transmission frame is transmitted, a receiver informs a transmitter of the validity of the received sequence and the result of the error check, when a transmitter receives the error message from a receiver, the picture frame immediately after the message is encoded by only the intraframe-encoding, the succeeding frames are encoded through interframe-encoding, so that the influence of the error is removed within a short time.
