发明名称 PERFECCIONAMIENTOS INTRODUCIDOS EN UN APARATO PARA LEER UN SOPORTE DE REGISTRO DE FORMA DE DISCO.
摘要 <p>An apparatus for reading a disc-shaped record carrier, which apparatus comprises provisions 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 color signal during reproduction via a PAL or SECAM receiver, a correction circuit has been provided. The correction circuit comprises a delay line for delaying the chrominance signal by one line period and a recombination circuit with a switch which is controlled by the command device. The 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.</p>
