Genlock (for Generator Lock) is a common technique where the video output of one source, or a specific reference signal, is used to synchronize other television picture sources together. The aim in video and digital audio applications is to ensure the coincidence of signals in time at a combining or mixing or switching point. When sources are synchronized in this way, they are said to be genlocked.

Genlock (for Generator Lock) is a common technique where the video output of one source, or a specific reference signal, is used to synchronize other television picture sources together. The aim in video and digital audio applications is to ensure the coincidence of signals in time at a combining or mixing or switching point. When sources are synchronized in this way, they are said to be genlocked.

Genlock performs four main functions: vertical, horizontal, frame, and color synchronization. These features are all normal parts of a standard composite video signal, which allows a TV or monitor to display an image properly. A fifth function, field 1 reference, is used mainly in broadcast video. A standardized signal which includes all of these, without any actual video image, is known as black burst. In the absence of a source of true black burst, many genlockable cameras will accept a standard composite video signal instead.
