What is needed to switch component video signals?
A dedicated component switcher is needed or a set of several high quality switchers that can be operated in parallel. The switcher, either single or part of a set, has to handle the incoming signals very accurately, as each signal (RGB or YUV) is part of the whole image, and if one part is impaired, the whole image becomes distorted. For example, if a switcher cannot transfer and match the RED signal to the same level as the GREEN signal, the whole image will suffer and have wrong colors and wrong brightness. The inputs and the outputs of the switcher should match the cables perfectly in order to avoid “standing waves” and other unwanted phenomena. The cables leading to and from the switcher should be of best quality and have the same length to avoid cross delay problems.
