ABSTRACT:
A dual-deck VCR includes a delaying portion for delaying a color signal of 629 KHz reproduced from one deck by a horizontal scanning period, a color comb filter for removing crosstalk from the delayed color signal and a not-delayed color signal, a burst level processing portion for integrating the burst to output the integrated level of the burst and a color gain controller for controlling the amplitude of the color signal output from the color comb filter in response to the integrated level output from the burst level processing portion. The characteristics of the components of the dual-deck VCR are chosen so that crosstalk and a pickup noise generated from the non-uniformity of friction between head and tape are removed.
