There's a thread in another forum about the online BBC News being delayed by two minutes. Someone said that it didn't really matter, but another made a tongue in cheek remark that it would do if the 4 minute warning was given out!

The delay was said to be down to how the internet works and it was pointed out that satellite transmissions are slightly delayed too because of the time it takes for the signal to get into space and back again.

This made me wonder if Virgin Media TV has a lesser delay on the line fed HD channels because the satellites up and downlink times are cut out of the distribution chain. Conversely the delay is probably longer for SD channels as these are fed by satellite.

So, if a nuclear attack looks imminent, would Virgin Media customers be advised to tune into an HD news channel to get their full 4 minutes worth!!!
