You're telling me they couldn't digitize it by simply having someone behind the ref say, 22 1/2 yard line is the first down. Then just paint a computer generated graphic stripe across the field.
The reason, of course, is that the camera's are not sending the signal back to the truck digitally. It's all still analog, apparently. I'm amazed at that.
As PrairiePat said, the problem is keeping the line visible above the turf, but below any players that go over it. Just drawing a line at the appropriate orientation would be trivial whether it's a digital or analog system (and where did you get the info that their cameras send an analog feed? I'd be very surprised if that were true, especially with the bandwidth you'd need to send an analog HDTV signal.)That seems like an incredibly complicated way to do it.

If this were all digital, the line would appear no matter the camera angle. It would be based on a simulated model of the entire field, with every angle already pre-programmed for every stadium.
OK, Pissah, get cracking, link me to explanations of all the other overlays they do now
The very first time I saw the yellow line on TV I thought it was real.
