Wow, what is this?

The device in the photo is the beating heart of television.
It's called a video switcher, live streaming switcher, or production switcher, and its job is to build the final picture you see at home on your TV screen.

If you watch a broadcast on screen, you'll notice it's made up of a huge number of elements.
There's the background layer, above it video windows carrying studio feeds, a Zoom interviewee, a field reporter, or a video file.
On top of those come additional elements, such as lower-thirds and guest name titles.
All of this information is gathered from an enormous variety of sources —
studio cameras, Zoom, a browser, a video player, and more — and everything ultimately converges at the production switcher.
The person operating the switcher is the television director.
The director is effectively in charge of all the visuals inside the broadcast control room, deciding at every moment which camera angles and elements appear on screen and how.
The many buttons on the switcher are designed, among other things, to allow smooth transitions between pre-configured layouts — so that switching to, say, a combined view of the studio together with a field reporter and a lower-third title appears on screen with a single button press.

I haven't operated one of these switchers during a live broadcast yet, but it's definitely on the list now that I've studied its technical architecture in depth.
If that ever happens and goes smoothly, I'll come back and report 😉
I took the photo some time ago in the control room of one of Israel's TV channels — and it's not Channel 10. If you recognize it, there's a good chance we've crossed paths before ☺️
