Abstract

PURPOSE: To increase the S/N other than red and cyan, by converting the color signal and performing recording so that the maximum level of the color signals can be made equal.
CONSTITUTION: The color TV signal inputted to the terminal 1 is given to the low pass filter 5 and the band pass filter 2. The filter 5 separates only the luminance signal, it is FM-modulated at the FM modulator 6 and given to the adder 8. On the other hand, only the carrier chrominance signal is separated at the filter 2, conversion is made so that the maximum level of chrominance signal of each color can be equal at the amplitude uniform conversion circuit 3, frequency conversion is made at the frequency conversion circuit 4 to lower frequency band. It is added with the FM modulation luminance signal at the adder 8 and recorded with the recording magnetic head 9. Further, the luminance signal from the filter 5 is given to the synchronizing signal separation circuit 7 to separate the synchronizing signal, which is used to separate the burst signal having the reference phase information at the circuit 3.
