Ofcom plan for 4 HD channels - Techwatch Support Forums: Digital & Satellite TV, FTA, Cable, Computers, Mobile Phones, Apple and General Tech Forums

Ofcom chief executive Ed Richards has said the regulator has drawn up a plan that would allow up to four high definition channels to be broadcast on the DTT system. Speaking to the Broadcasting Press Guild, Richards explained the plan had not been greeted with universal enthusiasm by the public broadcasters, which had been seeking gifted capacity after digital switchover.

Richards explained that the combination of new compression technology and a reshuffle of the existing DTT line-up could create additional capacity for HD: “The whole point is that we can use spectrum space more efficiently,” he said. Richards is not proposing a wholesale shift to either MPEG-4 or DVB-S2, but these technologies could be used for new services.

“There is a debate about how much you can squeeze in, we’ve got a view, but we have commissioned some independent research which we will make public in due course. We genuinely believe that you can get four HD channels,” said Richards. He hinted that after initial scepticism, some broadcasters were now coming round to Ofcom’s proposals.

DVB-S2?

Has DVB-T2 standard even created yet?

Still its not the gifted spectrum broadcasters want is it

, this will end up being "HD-Lite" crammed in on existing Digital Spectrum.

Just out of curiosity, would it be possible to have four standard definition 'quaters' being broadcast, and then have them stitched together?

-------------------------
|
Channel1 | Channel 2
|
-------------------------
|
Channel3 | Channel 4
|
-------------------------

Or would that just be too complex?

Im probably wrong but they are not right next door to each other say Mix one is not on Channel 33 and Mix two is not on Channel 34.

Good spot!

Yes, DVB-T2 is now certified. It's based heavily on DVB-S2 and will transport MPEG-4.

The attached Ofcom document is very interesting, and discusses the recent DTT HD options etc.

Yeah and its every press release on every hd blog and media site I can find.

Are people just stupid or dont even proof read the stuff they are copying?

If that's what the press release says, it's not my job to go correcting them!
