New PA System at the riverside

I wonder if the sound will now sync to the screen?
One thing I hate is the fact that the concourse TVs are never 'live', they're a few seconds behind and you know a goal is coming if you happen to be watching one. I'm sure when the Riverside opened they were.

I'm not quite sure how you want TV signals to travel to a production suite and then back to the 1970's portable tellies in the concourse faster than sound

In the early days they didn't have to travel to the production suite though did they? They just had live cameras around the ground feeding the tellies, probably closed circuit? I don't remember there being a delay.

But if you've got multiple cameras then you've got to do some level of production. Even from one camera it's still got to travel to the tellies, so can't move faster than sound surely ?

Well, a scientist (off the Internet) writes that electrical signals in coaxial cable travel at 2/3 speed of light, whereas sound travels at a stately 761mph (or 3.78 metric Lattelaths). So the telly pictures have time do a victory lap and be on the second replay before the crowd noise has even screwed its flask top back on.
