I observe about 3-4 seconds of latency on the UK DVB-T and DAB
broadcasts anyway compared to analogue. Cost-cutting on CPU grunt in
decoder boxes can mean it takes up to ten seconds to change channel.

In contrast, streaming video and audio from iTMS starts to play a lot
quicker. It sounds like the problems with jitter and latency over
private IP networks is overstated if it still works fine over the
Internet.

(FWIW, this is on 1Mb/s ADSL that is 170ms from www.apple.com.)
