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.

How does LTC timecode work?
Longitidinal time code (LTC) is a timing signal that is part of an audio tape recording. It is recorded on a track that runs lengthwise along the tape, which is why it is called longitudinal. LTC is one of two timing codes adopted by the Society of Motion Picture and Television Engineers ( SMPTE ) in the 1960s.
What is Smpte timecode used for?
Time code, sometimes known as SMPTE time code or SMPTE code, is an electronic signal which is used to identify a precise location on time-based media such as audio or video tape or in digital systems. (SMPTE refers to the Society of Motion Picture and Television Engineers.)
What is HDMI time code?
Timecode (TC)
This is used to synchronize multiple devices and media (both audio and video) on a metadata level. Genlock (generator locking) is most often simply called 'sync', it's even labeled as such on lockit boxes.
What is a time code generator?
Timecode generators produce a signal, usually an audio track, that marks out certain events in recorded footage. These signals can be a regular pulse like a metronome, common where there are a lot of people speaking, or for busy events.
