Abstract
A crosstalk cancelling circuit for a VTR eliminates adjacent-track crosstalk in a playback down-converted chrominance signal, with the resultant signal and a playback luminance signal being supplied to respective output terminals for re-recording by another VTR. Substantially improved display image quality is obtained from the re-recorded video signals, by comparison with prior art methods.
