Abstract
A color TV signal is recorded on an information carrier and includes a luminance component which occupies a predetermined luminance frequency range and a modulated chrominance subcarrier. In a conventional color TV signal, the modulated chrominance subcarrier occupies a first chrominance frequency range having a predetermined location relative to the luminance frequency range. However, the modulated chrominance subcarrier is assigned a different second frequency range which has the advantage that the modulated chrominance subcarrier in such range is easier to record. A color TV picture is to be reproduced from such recorded color TV signal. Firstly, there is introduced into such color TV signal a corrective phase shift bringing the signal into synchronism with a studio synchronizer. Only thereafter is the modulated chrominance subcarrier frequency-translated from the second back to the conventional first chrominance frequency range to thereby form a conventional color TV signal.
