I wouldn't say the trials weren't succesfull.....IMHO they 'pressured'
the Gov to allow HD on terrestrial which wasn't on the radar before.
I agree though that DVB-T was 'bandwidth hungry' for the HD channels
(up to 24mbps) and if T2 reduces this by the rumoured amounts this
will help enormously.
This makes an interesting read....

But the real reason they're switching over is that DVB-T2 can carry a lot more data on the same amount of spectrum - giving room for more channels (and of course, HD needs more anyway). It's all about revenue.
