Very informative explanation of something I've seen in practice during my Electronics studies in high school.
Back then they skipped over some parts of explanation making it very difficult to understand - now thanks to this post I get the full picture (pun intended) and I had my "aha" moment.
Tangential but Alec Watson of Technology Connections looked at a studio monitor that worked on the principle of cycling an LCD overlay over a monochrome CRT.
When I was growing up in Toronto, I want to say that I remember seeing these in use by “LiveEye” crews of CityTV whenever I went by an on-location shoot.
I remember for a CTF (I think PicoCTF?) we had to demodulate an image from sound using SSTV. This gave me a little more understanding of how that worked!
