Abstract
PURPOSE: To perform recording and reproduction by converting the color information component of color video signal into high region.
CONSTITUTION: The terminal 10 is the input terminal for the reproducing recorder, the luminance signal of FM modulation form for the input video signal is processed with the separation circuit 12 and the FM demodulator 14, and the chroma signal is processed with the separator 16 and the frequency convertor 18. The adder 20 gives the output NTSC video signal to the output terminal 22. 24 is a frequency divider, which produces N sets of signals for the frequency divided into 1/N with the shift circuit 26 and the signals are given to the signal selection circuit 28. The selection circuit receives error signal from the comparator 34 as signal. The comparator 34 compares the burst inserted with the burst gate 30 from the output of the frequency conversion circuit 18 with the reference subcarrier signal at the terminal 32. The signal at the phase selected with the selection circuit 28 is converted with the reference subcarrier signal and is given to the frequency conversion circuit, and converts the chroma signal from the chroma signal separation circuit into high band
