发明名称 Apparatus for recording a frequency modulated video signal with selective emphasis of its low frequency components
摘要 In an apparatus for recording a video signal on a record medium and having a circuit for separating luminance and chrominance signal components from an input video signal, a frequency-modulator receiving the separated luminance signal component and providing a frequency-modulated luminance signal, and an emphasizer low frequency components of the frequency-modulated luminance signal; a circuit is provided for selecting, as the luminance signal to be recorded on the record medium, either the frequency-modulated luminance signal from the frequency modulator when the video signal is derived from a television tuner or video reproducing apparatus having a relatively large frequency band, or the low frequency emphasized output of the equalizer when the video signal is from a television camera having a relatively smaller frequency band.
