That's pretty much what's going on across the regions with new cameras but no new apps/gallery. The camera/server input is HD, downscaled within the mixer etc to SD PAL, then down to CCM where it's upscaled to HD again.

I just had a butchers at the last opt out from Leeds on Breakfast and you can see it's still being transmitted in SD (you can see the picture quality drop when regions soft opt, and thin black bars appear on the left and right of the frame as network goes through the regional studio). One thing I did notice is how slightly out of focus the CU shot was, I thought it was my eyes to begin with:

Still, could be worse:

I think TW's must be the oldest studio cameras still in use across the regions now - and it shows. I imagine they were installed circa 2001, why does everything have a strange green outline?!

But if you compare both of the above (Leeds as an SD only, HD camera site and TW as an SD only operation) to a true HD studio you can see the difference in quality:

Leeds have had the newer Sony cameras for some time now, at least since May - so I expect this is what you're noticing - I think it's just TW and Hull left for the cameras to be replaced.
