ABSTRACT:
A chrominance signal reproducing circuit reproduces a chrominance signal with reduced crosstalk, as by using a comb filter, and a luminance signal reproducing circuit reproduces a luminance signal. The reproduced luminance signal is delayed by a horizontal line interval and a difference signal is produced representing a difference between the delayed and undelayed luminance signals. A summing circuit sums the difference signal with the delayed luminance signal to produce a crosstalk-eliminated delayed luminance output signal.
