。[Claims for Utility Model Registration] (1) In the chroma signal processing circuit of a video tape recorder that converts the chroma signal to a low frequency signal for recording and playback, the low frequency carrier signal is modulated with a color difference signal created from the RGB signal. A chroma signal processing circuit comprising: a modulation circuit that converts the output of the modulation circuit; and a conversion circuit that converts the output of the modulation circuit into a frequency. (2) The chroma signal processing circuit of the video tape recorder, which converts the chroma signal to the low frequency range for recording and playback, multiplies the color difference signal created from the RGB signal by the low frequency carrier signal and subcarrier signal, and converts the chroma signal to the low frequency range. A chroma signal processing circuit characterized by simultaneously creating a color signal and a chroma signal.
