A timecode (alternatively, time code) is a sequence of numeric codes generated at regular intervals by a timing synchronization system. Timecode is used in video production , show control and other applications which require temporal coordination or logging of recording or actions.
SMPTE timecode signal (A logic value 1 is expressed by a transition at the midpoint of a period. A logic value 0 is expressed by the absence of such a transition.) compared to the outwardly-similar Manchester code (A logic value 0 is expressed by a high-to-low transition, a logic value 1 by low-to-high transition at the midpoint of a period).
This converts 30 frame/second time code to the 29.97 frame/second NTSC standard. Bit 11, the color framing bit, is set to 1 if the time code is synchronized to a color video signal. The frame number modulo 2 (for NTSC and SECAM ) or modulo 4 (for PAL ) should be preserved across cuts in order to avoid phase jumps in the chrominance subcarrier .

Control Track Pulse: Most are familiar with the digital "counters" on VHS recorders and camcorders, viewed via the onscreen display (OSD) and/or a dedicated LED display. These numbers are sometimes in real-time format (hours:minutes:seconds), but are often only an ambiguous 4 digit sequential counter.
