What is the difference (technologically speaking) ?
Virgin TV at SD resolution = 576 x 400 (which is a lot less pixels to move about), and is MPEG3 encoded, which is a lossy compression that only transmits pixel changes. Hence a much smaller data footprint to move about.
Also, probably not on the 802.11 frequencies allocated.
