Abstract

PURPOSE: To reduce the color variation caused by the overload by making use of the fact that the S/N standard for the color signal is less strict than the luminance signal and thus lowering the amplitude of the color signal as well as the DC reference level.
CONSTITUTION: Color signal I and Q are supplied to input terminals 1 and 2 and then converted into the linear sequential signals via switch 4. This signal gives attenuation of about 5dB to the color compression signal through attenuator 7 and via clamper 5 and time axis compression circuit 6. While luminance signal Y is supplied to clamper 8 through input terminal 3. Switch 9 switches attenuator 7 and clamper 8 to deliver the output through terminal 10. This output is supplied to terminal 11 and then isolated into the color and luminance signals by switch 13 and via clamper 12. The compressed color signal is supplied to amplifier 14 to be amplified by 5dB. And this output is converted into the simultaneous signal at color signal interpolation circuit 16 through time axis expansion circuit 15. Thus signals I, Q and Y are delivered through terminals 17, 18 and 19 respectively.
