GoKawiilTechnical 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.
GoKawiil's interpretation of the reporting above, not reported fact.
Timecode synchronization underpins how audio, video and music gear stay locked together during production, a foundational need in broadcast and studio workflows. The TS1's decade-long success shows how solving a niche technical customer request—affordable sync hardware—can turn into a durable commercial product.
- LTC is a Bi-Phase Mark sync tone recorded on tape audio tracks for synchronization.
- The TS1 product supported SMPTE Drop Frame and MIDI Time Code for tape syncing.
- BCD encoding underlies how SMPTE/EBU timecode data words are structured.
