BBC forges ahead with DVB-T2 Freeview HD trial
Although Freeview has been destined for HD for quite some time, it has been far too long since we've heard about any progress. Thankfully, the Beeb is attempting to change all that, and it's moving forward with DVB-T2 tests. Reportedly, said standard is an advanced version of DVB-T -- the protocol currently used in the UK for digital terrestrial transmissions -- that provides an increase in efficiency and more bandwidth for more content. If all goes to plan, at least three high-def channels (one of which will be BBC) will be carried via DVB-T2 by the close of 2009, but it seems that ITV, Channel 4 and Five will have to cast lots for the remaining two openings.

I was all for HD on freeview originally, but now Ofcom are selling the spare spectrum created by the switch off, all it's ever going to be is a limited service with only 10 mbps available to each of the 3 HD channels - BBCHD on freesat currently uses 16 mbps! and Sky sports 19 mbps.
Plus to create this limited service they are going to rob bandwidth from existing channels, thus reducing the existing picture quality of SD freeview channels.
Surely freesat is the best way to go, with massive bandwith for SD and HD channels, plus proven S2 technology and cheap and available receivers.

Why don't ITV and channels 4 & 5 just build their own transmitters and towers?
Simple, no?

It's not a coverage problem that can be solved with more transmitters, it's a lack of spectrum problem i.e. Ofcom are selling it all off to the highest bidder (mobile phone companies) and not considering the benefit it would have to the UK public to keep the spectrum to expand HDTV.
Satellites don't have the same problems, and have oodles of bandwidth for HD channels. They have other benefits as well i.e 1 satellite can cover the whole of the UK rather than the cost of building & maintaining lots of transmitters. Plus they use solar panels to provide the power to transmit rather than mega watts of grid energy.
