| Summary: Linear/longitudinal timecode library | |
Linear (or Longitudinal) Timecode (LTC) is an encoding of SMPTE timecode data as a Manchester-Biphase encoded audio signal. The audio signal is commonly recorded on a VTR track or other storage media. libltc provides functionality to encode and decode LTC audio from/to SMPTE or EBU timecode, including SMPTE date support.
