1) rarely supported.
2) non-standard extension.
3) from STB to VCR when used for unattended recording
4) protocol not standardised, e. g. D²B.
5)bi-directional bus.
6)This pin is part of the shell/surround of the male connector. It is often connected to the overall screen in a cheap cable.
In equipment, Pin 21 should be connected separately to the chassis, but often it is merely connected to all the other ground pins.
output/input denotes symmetrical links. up/down denotes links to/from the TV set |
