Sorry there's something I'm missing. Are talking about games with no coverage at all?

When plays Djokovic vs Murray at US open, how many seconds before the TV/iPhone/Android applications transmits the signal/point/data?

I don't get why do they need a courtsider. Can someone explain what I'm obviously missing here???

The television delay for "live" sports seems to be surprisingly high (and has got worse since the advent of digital TV); we're talking 5-10 seconds here. Probably even more for streaming video.

Would be interested to see a breakdown of how all the additional latency is added. I'm sure part of it is from the increased of overlaid graphics. The recently-posted article about the virtual American football firstdown line mentioned that they added a 2/3 seconds delay to accommodate the technology (at least, in the original implementation).
