Abstract

PURPOSE:To prevent the quality of a reproduced picture from deterioration by replacing the picture signal with the data of the prescribed number of samples before which relates the ratio of a prescribed sample frequency to the chrominance subcarrier of an analog video signal to be reproduced. CONSTITUTION:During the period an error correction disabling signal generated by an error correction circuit at the disability of error correction is supplied to an input terminal 23, a signal switching circuit 26 connects a terminal (c) with a terminal (b) and, during the period other than the said case, connects the terminal (c) with a terminal (a). In the error correction disabling status, the circuit 26 is switched so that an output signal of a three sample delay circuit 25 is applied to a memory circuit 30 through the circuit 26. Thus, a digital video signal and a color burst signal are replaced with the data of 3 samples before and the replaced signal is sent to the circuit. At an output terminal, a picture can be reproduced so as to quiet noise, drop-out etc, on the picture even if error correction is impossible.
