ABSTRACT:
A device for reproducing a luminance signal from a magnetic record carrier has a first correction circuit (14, 37) to compensate for time errors in the signal being read and a second correction circuit (14, 38) to compensate for dropouts in the signal being read. The first correction circuit (37) comprises a first delay line (23) which provides a delay of half a line period (32 .mu.s). The second correction circuit (38) comprises a delay line (25) which provides a delay of one full line period. At least a section of the delay line (25) constitutes the delay line (23) for the first correction circuit.
