Longitudinal timecode. A type of SMPTE timecode that is recorded on the audio track of a videotape.

Stands for Longitudinal TimeCode. This type of SMPTE timecode, an alternative to VITC, is placed on an audio track. With LTC there is only one timecode per frame unlike VITC which can have one timecode per field.

A videotape time code encryption system found in certain VCRs and camcorders that enables edit controllers to communicate super-accurate editing commands.

Longitudinal Time Code (see Time Code).

Longitudinal Time Code. Time code information encoded in binary coded decimal (BCD) form which is recorded as an audio signal on a designated track of a VTR or an ATR.

Linear or Longitudinal Time code An alternative time code method to RCTC and VITC used by some professional computer editing packages. Information is recorded on the tape's linear edge track, so mono audio is lost.

Longitudinal Time Code. Type of time code recorded on one of the audio channels of video tape. Requires tape movement to read. (See also VITC.)

Linear Time Code. Time code recorded on a linear analog track on a video tape.

SMPTE time code standard usually recorded onto the linear audio track of a VCR or fed to a clapslate for later syncing with video.

Linear Time Code or Longitudinal Time Code. This time and address control signal standardised by SMPTE 12M has been in widespread use in the professional video and audio industries since 1975. It is typically written on a time code or address track of a video recorder and provides an individual frame number for each video frame recorded. LTC is also commonly used to distribute time of day information to wall clocks, automation systems and other devices throughout a television facility. In regions of the world using the NTSC or similar non-integer (1/1.001) frame rates, LTC locked to the video frame rate does not maintain accurate time and must be corrected regularly when it is used convey time of day information.

Longitudinal Time Code. A time code recorded alongside the images on a magnetic recording, often on one of the sound tracks.

Frame identification numbers encoded as an audio signal and recorded length-wise on the edge of a tape. (See EP, SP.)
