I’m curious as to how a ref will blow their whistle and get instant replay footage within seconds. Can someone explain this process to me?

This is sort of an ELI5 of how a single replay feed works:
Imagine you are walking down a path at a magic zoo. At this zoo, at the end of the path a new animal exhibit will always pop up and the path gets longer, you will never run out of animals to see. You and your friends start walking with a zoo keeper, and as you walk, the keeper puts a flag in the ground in front of every animal exhibit. No matter how far you and your friends walk, you will be able to instantly go back to any animal exhibit by using the flag she put in the ground. Even if your friends keep waking and new animals keep appearing at the end of the path, you can go back to the flags and see an animal you already walked by. When you’re done looking at the animal you saw, you can use the flag to catch up to your friends and the zookeeper.
It’s not perfect, but in this example, your friends are what is happening live at the football game, you are the person watching on TV, and the zookeeper is the EVS(Instant Replay) operator. The video feed is constantly recording what is happening. The EVS operator can go “back in time” along the path to an event they made (the flags) and show you the viewer at home a replay. While you are watching the replay, new flags are being made for new replays because the machine is always recording. There is also a producer sitting next to each operator in the truck that keeps notes of what replays are located at which point along the path so that when the director calls for it, it can be found quickly. Like I said, not a perfect example, but nobody else here was really trying to explain it to a 5 years old.
