Time code

1. Vertical interval time code (VITC). This is SMPTE time code that is recorded as video signals in the vertical interval of the active picture. It has the advantage of being readable by a VTR in still or jog. Multiple lines of VITC can be added to the signal allowing the encoding of more information than can be stored in normal LTC. 2. Linear time code (LTC). Time code recorded on a linear analog track (typically an audio channel) on a videotape. Also called longitudinal time code. Time code can be drop frame (59.94 Hz) that matches actual elapsed time by dropping occasional frames or non-drop frame (60 Hz) that runs continuously although it does not exactly match actual elapsed time.
