AKA Control-L. A communications
protocol for
VCRs and
camcorders. It
transmits most commands found on
remote controls, but it goes further by echoing back
timecodes which facilitate
video editing.
It is very similar to the
RS-232 serial protocol, but uses 0v/5v levels instead, and is designed in a way that allows multiple devices to use the same cable (
open collector).
