Hi,
Appearently something like video printers exist. They have "normal" video
inputs and are somehow able to extract a command to make a hardcopy from
the video signal. In my case the command is triggered by a button on an
edoscope control panel. Can anyone tell me how the trigger signal is
embedded in the video signal?
Thanks!
