Technical guide details SMPTE/EBU LTC timecode used in TS1 tape sync product
A technical write-up explains how SMPTE timecode, particularly the Bi-Phase Mark 'LTC' sync tone, is recorded onto audio or video tape tracks to keep equipment synchronized, alongside notes on VITC and BCD data encoding. The author traces the origin of the research to building a low-cost MIDI tape sync device, which became a long-running product called the TS1 supporting SMPTE Drop Frame and MIDI Time Code.
