Abstract

PURPOSE: To obviate degreasing of discrimination ability by generating digital signals having a reference level signal of an amplitude larger than the amplitude of the digital signals to be modulated.
CONSTITUTION: A reference level signal detection circuit 19 is inputted with the reproduction digital signal from an automatic gain control circuit 16 and the reproduction horizontal synchronizing signal out of the composite synchronizing signal from a synchronous separator circuit 21 and detects the presence or not of the reference level signal C in the reproduction digital signal. The output detection signal of this reference level signal detecting circuit 19 is applied to a gate circuit 18. The gate circuit 18 detects the presence of the reference level signal C and supplies the reproduction digital signal to a memory circuit 23 constituted by RAM, etc. when the detection signal thus obtained is applied. On the other hand, it cuts off the supply when there is no reference level signal C.
