Audio signal outputs.

Zo=50 Ω (within DC ±2 mA)

Detects the S2-compatible DC

superimposed onto the C signal.

4 : 3 video signal at 1.3 V or less

4 : 3 letter-box signal at 1.3 V or more

to 2.5 V or less

16 : 9 picture squeezed signal at 2.5 V

or more

This pin is pulled down to GND by a

100 kΩ resistor, so the 4 : 3 video

signal is selected when open.
