'''CTL''' ([[controlControl track]] longitudinal)''', or '''CTL''', '''timecode''', developed by [[JVC]] in the early 1990s, is a unique technique for embedding, or ''striping'', reference [[SMPTE]] [[timecode]] onto a videotape.

Similar to the way [[VITC]] timecode is embedded in the vertical interval area of a video signal, CTL timecode embeds SMPTE timecode in the ''[[control track]]'' area of [[helical scan]] video recordings. The advantage of both VITC and CTL timecode is that a precious audio track does not have to be sacrificed for [[linear timecode]].
