This is exactly right.
I used to work at a video duplicating plant where we controlled our source machines (Beta, DigiBeta, C1s, D2s, etc.) via a central computer. We had about 20 source machines providing movies, commercials, logos, and trailers to over 4000 VHS recorders divided into 14 racks.
Until we got the centralized computer management thingie, we used manual switchboards and our skills to start, synchronize, and switch between, different source machines providing logos, trailers, commercials, and features, making sure each "item" was properly synchronized after each other.
This was not so difficult with just trailers before a film, but if you had two source reels that needed to be switched in the middle of a movie, you had to make damn sure you didn't switch sources more than a couple of frames out of sync, or you'd get a really bad copy. It was a fun little game, but the computerized system, of course, made the whole thing much easier and much more accurate.
But of course, this accuracy depended on the accuracy of the OS the system ran on. A running video player controlled via RF over BNC cables doesn't provide interrupts, the entire thing had to be timed to the frame from within the application itself. And not for one source and one target, but for M sources and M targets. So you needed an OS which absolutely guaranteed a time slice from the kernel at an absolutely non-negotiable point in time.
That, at the time, would be Windows 3.11
