vertical interval timecode

Quick Reference

*Timecode information encoded along with the video signal, which typically appears in the UK as a series of white dashes recorded onto TV lines 19 and 21 in the vertical interval of a television image. The advantage VITC has over linear timecode (LTC) is that it can display usable timecode information when a videotape is either completely still or moving very slowly. The disadvantages are that VITC becomes unreadable when the picture breaks up: for example, when it is rewound at high speed, and because VITC is part of the video signal, it cannot be changed or inserted without re-recording the video.
