ABSTRACT:
For recording and/or reproducing color television signals steps are proposed which enable the crosstalk signal from an adjacent track to be suppressed during reproduction. This is possible both for the chrominance signal and for the luminance signal. For this purpose the polarity of the signals in the line periods in all tracks is switched during recording in periodically recurrent groups with the same pattern of consecutive polarities, the groups comprising at least four line periods and being offset relative to each other in adjacent tracks by at least one line period. During reproduction the signals scanned from the relevant track whose polarities have been switched, at least in respect of the chrominance signal, are restored to signals with the original polarities. The frequency spectra of the useful signal relative to the crosstalk signal from an adjacent track are then interlaced, which is utilized for suppressing the crosstalk signal.
