ABSTRACT:
An video signal processing circuit of a double deck VCR capable of preventing a deterioration of picture when dubbing, which includes a reproducing video cassette tape recorder and a recording video cassette tape recorder disposed in a single body, wherein the reproducing VCR transmits a luminance signal and a chrominance signal, respectively, to the recording VCR and includes a luminance reproduction processing circuit generating a high band detection signal to be transmitted to the recording VCR, and the recording VCR includes a first switch for switching an input signal and an output signal of a low pass filter for luminance signal in response to the high band detection signal so that the output of the low pass filter is outputted to a luminance signal recording processing circuit when a high band signal is detected and the input of the low pass filter is outputted when the high band signal is not detected, and a second switch for switching an input signal and an output signal of a band pass filter in response to the high band detection signal so that the output of the band pass filter is outputted to a color signal recorder processing circuit when the high band signal is detected and the input of the band pass filter is outputted to the color signal recording processing circuit when the high band detection signal is not detected.
