ABSTRACT:
Signal processing apparatus for processing a color video signal formed of a luminance signal and a color carrier signal reproduced from a magnetic tape, in which the signals include respective crosstalk components produced from the tracks adjacent the track being traced. The color video signal was originally recorded so that the crosstalk components are frequency interleaved relative to the signal in the track being reproduced, and signal processing apparatus permits the luminance and color carrier signals to be processed and the respective crosstalk components eliminated using only a single time delay element for both luminance and color carrier crosstalk components. The single delay unit is part of a comb filter and is particularly adapted for fabrication as a CCD element.
