Ofcom's road to Freeview HD gets explained

We'll warn you -- if you venture down to the full story on this one, you'll be wading knee-deep in some fairly technical hoopla. That said, those interested in exactly how Ofcom plans to get Freeview HD up and rolling when the 2012 digital switchover occurs in the UK will certainly find it of interest. As the story goes, the first three Freeview HD channels (BBC, ITV and Channel 4) are expected to go live in late 2009 when the Winter Hill transmitter is switched to digital-only. There are a grand total of six multiplexes to work with, and Ofcom has it planned to shuffle things around and use the now-empty PSB3 for high-def content. Sadly, the story ends with you needing a new set-top-box to digest the new signals, but hey, at least you can keep the same antenna. More technobabble awaits you in the read link.

BBC's DVB-T2 Freeview HD trials deemed a success

We're not quite sure what this means for the immediate future of OTA programming in the UK, but we suppose a "huzzah!" is in order either way. Reportedly, those complicated DVB-T2 Freeview HD trials that were underway have been successful, with Auntie Beeb achieving the "world's first reception of HD pictures over DTT using DVB-T2." If you couldn't guess, DVB-T2 is a successor to the existing DVB-T broadcasting protocol which provides additional bandwidth and more swagger to TV signals. In theory, the switch to DVB-T2 (in conjunction with the move to MPEG-4 from MPEG-2) will enable more high-def content to be available in the UK. Of course, when we say "more," we basically mean "any" -- estimates assert that just three HD stations will be available OTA in the UK by 2009, one of which will be owned by the BBC and the other two by ITV, Channel 4 or Five.

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.
