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.
