What is a frame synchronizer?
A frame synchronizer is a digital device that stores a frame of video in its memory and releases it at a very
precise moment. These little devices are essential if you want to make a seamless switch from one video
source to another. If the sources you are switching between are not synchronized with each other, the video
image falls apart at the transition moment, and the result is not pretty.
The SE-800 has a full frame synchronizer (also known as a time base corrector or TBC) at its Main and Sub
Source inputs (2 total) to insure switches without distortion and smooth, well-regulated video at its output. In
addition to its digital memory, a TBC also has controls that affect the look of the video that passes through it.
These controls are known as processing amplifiers, or proc amps; they control brightness, contrast, color,
and tint, though these may have different names in different applications.
For more information on some of these technical aspects, see the Appendix Tech Notes on page 53
