ABSTRACT:
In a video signal recording/reproducing apparatus for emphasizing an input video signal, recording by adding an additional signal necessary for recording, and de-emphasizing when reproducing, the emphasis processing is stopped on the time axis in a period in which the additional signal is to be added. Besides, by adding an additional signal before emphasis processing, the waveform deterioration in the end portion of the effective period occurring due to the addition of additional signal after emphasis processing is decreased, and a favorable waveform reproduction is realized over the entire period of the effective portions.
