It always was Composite video in the old days,as it is a more rugged format than the others,needs only one cable/link channel,& everything is designed for it.
Wasn't it all Betacam in those days? They stored video as separate luma/chroma.
David Kilpatrick did a great tour, easy to listen to and informative. Two thumbs up as they say.
An overall excellent excellent video in so many ways.
He was a good guide, but I can't help feeling he was holding back a bit; he didn't exactly seem enthused and very driven about it (mind you, it's his daily job - he's seen it a thousand times); it may just be the bloke's character though. I loved the video, but I'm more looking forward to being back in the lab, with Dave's infectious excitement and passionate enthusiasm - I'm one for details - EXCESSIVE details, and David seemed to only skim over the basics, although I can appreciate HOW much there is to talk about for a limited amount of time in a place like this... maybe I'm wrong, who knows

I got the exact opposite reaction. Dave¹ asked a question, and Dave² answered quickly and comprehensively. I quite like the interchange between the two.

Not jaw-dropping, but on a related note...

I really enjoyed this EEVBlog episode: particularly David K's contributions. My understanding is that the signal combiner is, in essence, a cavity tuned to the amplified signals. It would be interesting to learn more about cavities and particularly how the input signals are introduced to the cavity, and the output signals derived: are they electromagentically / capacitively coupled with the cavity acting as a form of low loss faraday cage?
I'm still pondering what that was that required the "widow stick"?

If something is charged up to thousands of volts and you touch it you are dead, leaving your wife a widow. So you short it to earth using said stick to make sure it cannot be charged up to thousands of volts before you work on it.

I know, I know, but what was that part that he pulled out? It was a tube, it had rf shielding, it was heated, they could have told me it was a warp core.
The prop makers could not have made cooler looking stuff than what's there.
It was a valve (or vacuum tube, if you prefer). A very big expensive one.
I still can't believe that at least some of this beautifully crafted gear is not diverted to our musea for future generations to marvel at and learn from.
