—
Detects the S2-compatible DC
superimposed onto the C signal.
4:3 video signal at 1.3V or less
4:3 letter-box signal at 1.3V or more
to 2.5V or less
16:9 picture squeezed signal at 2.5V
or more
These pins are pulled down to GND
by a 100k
Ω
resistor, so the 4:3 video
signals are selected when open.
