Techopedia Explains Generator Locking

Genlock technology is used to sync a number of cameras together so that if the source is switched from one to another, the frame rate, color burst and line rate remains the same between them. It is important to keep all of the video sources in sync and in the same phase to ensure all the video signal sources are in the same fields and frames at the same time. This allows the viewer to see the correct picture without distortion or delay. Genlock works by aligning the first signal from the first source with the first signal from the second source.
