Video signal recording and reproducing apparatus a frequency down-cinverted luminance signal into the vertical retrace line interval of a recording signal

DETAILED DESCRIPTION Accordingly, it is an object of the present invention to provide a video signal recording and reproducing apparatus which can improve resolution by compressing a high band component of a signal and recording the same on a vertical retrace line interval for reproducing.
In accordance with one aspect of the present invention, there is provided a video signal recording apparatus, the apparatus comprising a high band signal recording process means wherein a high band signal separated from a video signal is transmitted to a low band to thereby be compressed and be outputted to a vertical retrace line interval by control of a control means, and a recording means for recording on a recording medium the high band signal and video signal processed from the high band signal recording process means.
In accordance with another aspect of the present invention, there is provided a video signal reproducing means comprising a reproducing means for reproducing the video signal recorded on the recording medium, and a high band reproducing process means wherein the high band signal compressed and reproduced on the vertical retrace line interval is restored from the signal reproduced at the reproducing means to thereafter transmit the same to the high band for outputting.
