Abstract

PURPOSE: To simplify the constitution, and to enable the deterioration of a demodulated color-difference signal output in a weak electric field to correspond to the error rate of a color discrimination signal, by providing a color discrimination signal detection circuit which detects a color discrimination signal in every period from a color signal from at least either or both the 1st and 2nd demodulator circuits and supplies it to a control circuit.
