  • Video signal recording and reproducing apparatus a frequency down-cinverted luminance signal into the vertical retrace line interval of a recording signal
    Patent number: 5585928
    Abstract: A video signal recording apparatus includes a high band signal recording process unit 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 units, a recording unit for recording on a recording medium the high band signal and a video signal processed for the high band signal recording process unit, and a video signal reproducing apparatus includes a reproducing unit for reproducing a video signal recorded on the recording medium and high band signal reproducing process unit wherein, among the signals reproduced in the reproducing unit, a high band signal reproduced and compressed in a vertical retrace line interval is restored to thereby be transmitted to a high band and outputted.
