  1. In broadcast video situations, the LTC generator should be tied-in to house black burst, as should all devices using timecode, to ensure correct color framing and correct synchronization of all digital clocks

  2. Linear (or Longitudinal) Timecode (LTC) is an encoding of SMPTE timecode data in an audio signal, as defined in SMPTE 12M specification. The audio signal is commonly recorded on a VTR track or other storage media

  4. Accomplished by using a generator that generates both black burst & video-resolved word clock, or by synchronizing the master digital device to video, & synchronizing all subsequent devices to the word clock output of the master digital device (& to LTC)

  5. Made up of 80 bits per frame, where there may be 24, 25 or 30 frames per second, LTC timecode varies from 960 Hz (binary zeros at 24 frames/s) to 2400 Hz (binary ones at 30 frames/s). and thus is comfortably in the middle of the audio frequency range
