Frame synchronization (video)
||This article needs attention from an expert in Entertainment Technology. (February 2013)|
In video, frame synchronization is the process of synchronizing display pixel scanning to a synchronization source. When several systems are connected, a synchronization signal is fed from a master system to the other systems in the network, and the displays are synchronized with each other.
A frame synchronizer is a device used in live television production to match the timing of an incoming video source to the timing of an existing video system. They are often used to "time in" consumer video equipment to a professional system but can be used to stabilize any video. The frame synchronizer essentially takes a picture of each frame of incoming video and then immediately outputs it with the correct synchronization signals to match an existing video system. A genlock signal is required to provide a means for video synchronizing with the house reference.
