Keywords:  sync, synchronize, camera, vtrs, pulses
The use of composite video, composite sync, or vertical or horizontal sync to synchronize one or more cameras is known as Gen-lock.
A method used to synchronize one or more cameras by external means. Typical methods are composite video, composite sync, and horizontal or vertical sync.
Circuitry that synchronizes the television signal source of two or more devices. All video signals contain synchronization pulses that are used to reconstruct the picture on the CRT. When several signals are used together through a common device such as a switcher,they all must be operating on the same sync. A master sync generator provides gen-lock to signal generating devices (cameras, VTRs, switchers, etc.) so that they can operate in sync.
