Hurray we've gained an extra HD channel on Freesat.
... and yet people say boo hoo we don't have our regional headline and news "this is crap"
Have you thought what you are asking for?
To do regional variations the BBC would have to have the bandwidth and money to uplink separate BBC HD channels for every region (just like BBC One SD).
It looks like what we are currently seeing is "phase 1" of BBC One HD, perhaps there will be some visible differences later. I found this out when Googling.
I wondered about how it was being done, for instance Merlin is said to be made in 720P, so didn't qualify for the original BBC HD channel, it was just down-scaled to SD for BBC1. Now that BBC1 HD exists I wondered if we get 720P upscaled to 1080i or down to SD and then up to 1080i
I didn't find my answer, but got some interesting information from Andy Quested's blog. He's one of the BBC's key people on matters HD. Google for
