Abstract

PURPOSE:To enable to limit the propagation of an error in the course of transmission to the prescribed limit, by splitting an encoding signal of one scanning line of the picture signal into (n) pieces, adding (n) pieces of each split head value to the encoding signal, and executing its transmission. CONSTITUTION:A signal S5 which has been encoded by A/D converter 10, substracter 14, forecasting encoder 12, equalizer 11 and adder 13 is stored in the register 16 by one scanning line portion. In the control circuit 17, a clock signal for equally dividing 1 scanning line into (n) under the synchronizing signal u1 is generated, and by this period, a prescribed number of pieces u3 of the output signal u2 of the adder 13 is taken out, a reference block is prepared by storing said signal in the head of the register 16, and it is transmitted through the desirablizer 15. The receiving side detects the head reference block by the control circuit 25, and stores the signal v1 in the register 24. After that, a decoding signal of the head position of each block is compared with the storage signal v2 of the register 24 by the error correcting circuit 26, and in case of uncoincidence, an error is corrected by replacing with a signal of the register, and the propagation of an error is limited to the prescribed limit.
