ABSTRACT: An apparatus for reading a disc-shaped record carrier, which apparatus comprises previsions such as a command device, for reproducing the recorded information in a scanning sequence which differs from that during recording. In order to maintain the line-sequential phase alternation of the colour signal during reproduction via a PAL or SECAM receiver, a correction circuit has been provided. Said correction circuit comprises a delay line for delaying the chrominance signal by one line period and a recombination circuit with a switch is controlled by the command device. Said recombination circuit, depending on the position of the switch, supplies an output signal which consists of the combination of the luminance signal and either the chrominance signal or the chrominance signal which has been delayed by one line period.
