V / I output
Outputs R-Y (V) or Q signal.It
includes LPF that can remove carrier.
The chroma signal that routed ACC
and TOF circuits (before demo input)
can be monitored by pulling up this
pin at 10k

control
Outputs the result of whether the
signal is PAL, SECAM or NTSC.
Connect the output to the 1H DL IC.
In the case of discrimination between
white or black, the voltage just before
that is retained.
The voltage immediately after
turning-on is not fixed.
