World Cup 2010 in HD?

High definition is a term you'll see used on all forms of media today, offering greater picture clarity as well as richer and more natural colours, it's a service that most would like but so far it has remained a service that has proven to be too expensive for many.

Before high definition becomes a standard in the UK, it has been essential that a freeview offering of HD material be made available. Though the BBC have carried out trials of their own HD service, the deployment of HD channels via freeview has remained in doubt following claims of limited transmission capacity.

Having signed a non-binding memorandum of understanding however, BBC, ITV, Channel 4 and FIVE look set to deliver HD channels via freeview from as soon as 2009 using existing transmission bandwidth.

The agreement encompasses:

  • The use of new technologies, which will increase the capacity available on Freeview
  • A rearrangement of some of the channels carried on Freeview, in line with Ofcom's suggestion, setting aside one of the BBC's two multiplexes for the carriage of not only BBC HD but also ITV HD, Channel 4 HD and – as soon as technically possible – Five HD.

Upon approval by the BBC Trust of BBC's proposed HD channel, BBC HD, BBC Director General Mark Thompson stated "We are delighted that the BBC Trust has approved the BBC Executive's high definition television proposals, allowing us to launch the UK's first free-to-air, mixed-genre public service HDTV channel."

Despite this big step in the right direction, we don't expect to see any signs of BBC HD material via freeview until late 2009, if not early 2010. Other broadcasters, such as Five, may be waiting until 2012 for sufficient capacity to be made available.

Great! Will existing HDTVs with Freeview tuners be able to pick up the HD signal, or will there be further equipment required?
I think it would be dependent on the freeview box, as if you don't have a box with HDMI or component then you won't be able to physically output the HD signal via scart or composite. You can purchase a HDMI freeview box for as cheap as £19.99 from argos;

they won't, unfortunately.

whilst no decisions have been made yet on which technology to use on hd freeview, it certainly won't be something which existing hardware could possibly cope with - it'll almost certainly be a newer codec (h264 instead of mpeg2), and possibly a newer transmission standard (bbc mimo or dvb-t2 instead of dvb-t)

so anyone with existing kit will need a new box capable of dealing with h264 and dvb-t2/mimo
2009 as a date is a real shame. I'd hoped, judging by the details the BBC Trust released a few months back, that 2008 was the target they'd be aiming for. Oh well.

According to other sources, Everything on Mux B (listing here: Terrestrial - Digital Spy) will be moved to other multiplexes. Mux B will go through a “mode change” i assume that means changing the QAM value, probably to QAM64, increasing bandwidth by 20%. DVB-T2 will also be used increasing capacity by a further 30%. Finally, MPEG-4 will be used.

Because DVB-T2 will be used, no only will you need new STBs or integrated decoders, DVB-T PCI, USB and PCIe cards will also need to be replaced.
