VITC
Vertical Interval Time Code (VITC) is timecode information encoded in the
vertical retrace interval of the video signal (this is the time when the beam is
getting back to the top of the screen). The advantage of VITC is that the timecode
value can be read when the video deck is paused, and is accurate to the frame.
