- Tri-level sync is an analogue video synchronization pulse primarily used for the locking of high-definition video signals (genlock). It is preferred in HD environments over black and burst, as timing jitter is reduced due to the nature of its higher frequency. It also benefits from having no DC content, as the pulses are in both polarities. (en)
- 三電平同步 (英語：Tri level sync) 是一種主要用於鎖定高清(HD)影像訊號的一個模擬影像同步脈衝。 三電平同步由於較高頻率的特性，因此它相較於訊號是高清(HD)影像訊號的首選。它也優於具有兩種極性脈衝的直流，因為三電平同步多了-1脈衝準位。 (zh)
