'''VANC''' stands for '''Vertical Ancillary Data Space'''. This is part of the transmission signal for digital video that is not displayed on the screen as video frames. It is available as a means of carrying data other than the image.
It is described in the [[Society of Motion Picture and Television Engineers|SMPTE]] specification SMPTE-334M "Vertical Ancillary Data Mapping for Bit-Serial Interface".
In the [[PAL]] and [[NTSC]] analog television systems the [[Vertical blanking interval]] (or VBI) is similarly used to carry non-display data.
