ABSTRACT:
An apparatus for reproducing, from a recording medium, a composite signal in which an image signal and a non-image signal are multiplexed on a time axis. The apparatus includes (a) a reproduction device for reproducing the composite signal from the recording medium; (b) a detection device, coupled to the reproduction device, for detecting a drop-out portion of the composite signal reproduced by the reproduction device; (c) a discrimination device, coupled to the reproduction device, for generating a discrimination signal to discriminate between an image signal portion and non-image signal portions of the composite signal reproduced by the reproduction device; and (d) a replacing device, coupled to the detection device and to the discrimination device, for replacing the drop-out portion of the composite signal with a corresponding replacement signal, reproduced a predetermined period of time before the composite signal, in response to (i) a detection of a drop-out portion by the detection device and, (ii) the discrimination signal generated by the discrimination device.
