Analogue TV was much faster with much lower latency than digital TV.
If there's one thing I don't need from a TV, then it's low latency. The pause, rewind, and skip functions are some serious stuff, on the opposite.
It was funny during the transition period. You could hear through the timing of cheers during football matches who in the neighbourhood was analogue and who was digital.
But yeah, recording features were really nice for the transition to streaming.
It was so in the football world cup of 2014 IIRC. Outside was public screening and they had a sat dish while we watched a delayed stream. We could hear the goal seconds in advance. But that's an edge case.
Latency doesn't matter if you're just watching television, but it's very important if you're trying to hook a game console up to it.
Speaking of analog: Light Guns don't work on modern televisions due to the high latency relative to CRT screens (which had essentially zero latency).
Mostly because of the timing of the electron beam. That let the game see which target you hit. Otherwise you could hit everything by shooting any bright light.
Oh man, remember when you just had to press the channel number on the remote.
Now you gotta use menus in a Smart TV that takes 2 seconds to process an input event.
Reminds me of the time I had to make an interface for a set top box by Deutsche Telekom. It was severely underpowered and I had to work with some very quirky browser. I think the browser was based on Internet Explorer.
It was super slow and couldn't handle anything asynchronous. Which meant that it would lock up for even the simplest operation. And they insisted on their buttons having button down animations. Which meant that I had to slow down the incredibly slow machine artificially so that you could see the animation. And it wasn't enough to slow it down just for the animation duration. You had to give it some extra time because it was so damn underpowered. I think in the end a button push took a whole second extra time.
And it was still faster than what they had produced themselves before that, even though their thing didn't have any animations.
The worst was that those machines actually did have a fancy hardware accelerated interface one could use. But for some reason they weren't ready yet for that. So everything I had done was just a placeholder anyways.
Back when Nintendo light zapper games worked, the power bars you stopped on games were accurate, and guitar hero was perfectly synced in timings.
I mean, the vacuum tubes will take quite a while to warm up at the start.
