There is a shocking disparity between bit rates, very few fixed bit rate channels. BBCHD appears to be only beaten in the budget bandwidth stakes by LuxeHD!
Most surprising is how they can claim to offer FIVE times the quality on BBC HD to SD? Yes I appreciate there is a difference in encoders and all of the other sorcery we have read about this week . . . but seriously!
To my, rather naive eyes, if the BBC were using some fantasic, magical, low bit rate, same PQ encoders, surely Sky would be all over them in a heartbeat?
