Recommend Split Article

It's true that "vision mixer" is a uniquely European term, as I've never heard of it before. The device pictured in the image is what I know as a production video switcher or a production switcher. This ambiguity is referenced in the article, and that is fine. However, the subject of this article is not what I would call a video switcher. When I think of a video switcher, I think of a device that routes audio from inputs to outputs. Within the category of video switchers, there are many subcategories, including:

Video Switcher (routes multiple inputs to one output)
Matrix Switcher (routes multiple inputs to multiple outputs, and one input can be routed to multiple outputs)
Seamless Switcher (routes multiple inputs to one output "seamlessly", i.e. with no video gremlins during the switch; usually incorporates automatic transition effects)
Scaling Switcher (routes multiple inputs to one output, and automatically performs format conversion if necessary)
Production Switcher (what this article describes. like a seamless switcher, but with much more user control and flexibility)

Many of the switchers that only route to one output actually route to two outputs. That is, they have a program output (which is what is currently being displayed or broadcast) and they have a preview output (which shows what is cued up to be displayed next).

Also, many of these switchers will optionally switch the audio associated with the video. Some can also switch the audio independently of the audio (i.e. breakaway audio). Some do not route audio at all. Here is an example of a matrix switcher.

I would recommend that this article focuses on what I call production video switchers, and that the term "video switcher" has its own article.

Cleen Feed bus

I have added a reference to the clean feed signal. I don't know if this term is used in US, I am quite sure it is in EUrope. However, since it is reported in any Sony, Grass Valley, Philips or Snell & Wilcox switcher I have seen, it should be of common use.
