ABSTRACT:
A reproducing processor for processing a video format signal and allowing, during dropout, selective inhibition of at least one of dropout compensation and video signal correction processing, for preventing production of uncorrectable errors due to a processsing of digital data of the video format signal. Included are: a dropout compensation component for carrying out dropout compensation for a video format signal obtained from the reproducing component in the absence of a digital data signal reproducing command, and not carrying dropout compensation in response to the digital data signal reproducing command; and a signal selection component for selectively outputting an output of a waveform shaping component in response to the digital data signal reproducing command, and for selectively outputting an output of a signal processing component in the absence of the digital data signal reproducing command. The signal selection component may be excluded, whereupon the reproducing processor outputs, respectively, separate outputs of the signal processing means and waveform shaping means.
