I2C BUS DATA
input/output
signal
Separate Y/C signals by using LC-tank circuit or LPF,BPF for Y/C signals level adjust.
And then mix both signals for sub-picture input video signal.
(The above external circuit processing aims at controlling white compression of
sub-screen input luminance signal and strengthening the color playback function of
sub-screen input signal in the case of weak electric field.)
Units Resistance : Ω
Capacitance : F
