ABSTRACT:
An apparatus for recording and reproducing a video signal has a recording portion and a reproducing portion. The recording portion has an analog-to-digital converter for converting analog video signal to digital video signal, a wave form data extraction circuit for extracting digital wave form data expressed in 8-bit detail and carried in a vertical blanking period of the video signal, and a converter for converting the digital wave form data to a quantized wave form data expressed in 2-bit detail. The video signal is recorded on a tape together with the quantized wave form data. The reproducing portion has a wave form data selector for selecting the quantized wave form data, a counter converter for converting the 2-bit quantized wave form data to the original digital wave form data of 8-bit detail, and an adder for adding the digital wave form data in a vertical blanking period of the video signal.
