Erm.......think again people
Just some comments to consider:
1) A lot of programmes are currently filmed in HD, as the broadcasters have been re-equipping for some time, in order to produce better quality.
2) The newest HDMI spec (v1.3), improves the colour depth significantly....so in time, if HD broadcasts follow the HDMI spec, then the picture quality will improve enormously...
3) If you see a native 720p or 1080i resolution broadcast (rather than one that's been upscaled from a lower reslution "source") then most people will notice a significant difference, whether on PAL or NTSC....
4) OfCom has really messed up the entire radio and TV spectrum both on DAB as well as on DTT. They've claimed to have the consumers best interests at heart, but they are hanging on to RF spectrum on both systems for unknown reasons - it's as if they are scared to allow these digital mediums to be developed properly, so instead we have low resolution DAB and NO HD content on Freeview.....all because of a supposed "lack of bandwidth"....! Pull the other one...OfCom controls the entire licensed RF spectrum...
5) The Olympic Games are being held in London in 2012 (assuming most people didn't know this already :-) ....and the host broadcaster (I assume it'll be the BBC), will be outputting HD content for the rest of the world, but we'll have to accept SD on Freeview.....it's likely that the only way some UK-based people will be able to watch the Games in HD will be via a Sky HD box....and you can bet that'll still be a premium service...!
I think it's time that OfCom had a change of management and instead of fudging things, instead took a pro-active stance and did things properly...
