Patent ID: 6925244

Claim:
An apparatus, comprising: a decision unit detecting when a video signal includes a color signal, detecting when said color signal has predetermined characteristics, generating a color killer control signal when said video signal does not include said color signal; low pass filter unit receiving said video signal, outputting a low frequency band signal, said low frequency band signal being lower than a first cut off frequency by setting said first cut off frequency higher than at least a color signal sub-carrier frequency when said color killer control signal is generated, said low frequency band signal being lower than a second cut off frequency by setting said second cut off frequency lower than a color signal sub-carrier frequency when said color killer control signal is not generated; a frequency modulation unit frequency-modulating said band signal output from said low pass filter unit; and a recording equalizing unit receiving said frequency modulated signal, peaking a predetermined luminance signal frequency band cutting off the frequency down-converted color signal frequency band when said color killer control signal is not generated, and not cutting off the frequency down-converted color signal frequency band when said color killer control signal is generated.
