Abstract
In order to prevent phase errors in the transmission of a colour television signal in time and frequency multiplex without taking account of image interference, a reference signal is inserted during image generation in at least one line of each complete image which contains no image information in its image blanking region. In the image blanking region of the line concerned the reference signal has a sloping component continuously rising with the amplitude on which a sine-wave oscillation with the frequency and phase of the colour carrier is superimposed. Throughout studio processing and broadcasting at the transmitter to preparation at the receiver, the reference signal remains inseparably linked to the image information of the appropriate complete image.
