PURPOSE:To reduce a noise in a picture search, etc., and to obtain a picture easy to see by outputting a reproducing signal recorded respectively when the level of the reproducing signal is large, when the level of the reproducing signal is small comparatively. CONSTITUTION:A control circuit 15 outputs a readout pulse to a controller 17, when the level of a signal RF is below a prescribed value. The controller 17 setting a signal outputted from an oscillator 18 as a clock, reads out a reproduced and demodulated video signal stored at a memory 13, and outputs it to a D/A conversion circuit 14. The D/A conversion circuit 14 converts an inputted digital signal to and analog signal, and outputs it to the contact R of a switch 11. Since the switch 11 is switched to the contact R side when the readout pulse is outputted, the signal is outputted to a succeeding stage, etc., through the contact R of the switch 11.
