Dad's Army in HD

Dad's Army on BBC2 HD tonight is listed as being an HD originated
programme. Does anyone how it can be in HD as I thought it was shot in the
studio on SD colour cameras. It's not one of the filmed episodes. (Except
for some of the outside scenes) The picture looks noticeably sharper than
the average Dad's Army episode. Tonight's episode is entitled "Manhunt".

Had you not said "it's not one of the filmed episodes" (implying recovered
from a film-recorded copy made for overseas) I've have wondered whether the
film had been telecined in HD, though given that the original was made using
SD studio cameras, with a bit of spot-wobble to blur the raster on the film
copy, it would have been disingenuous to describe that as HD.

Could it simply be that the listing is wrong when it says "made in HD".

Well it was the fact that it looked noticeably better than your average
Dad's Army episode that led me to check the listings.

the bbc mis-describe stuff as hd a lot on their hd channels.
still, it will look better than on the sd channel even if it's not HD.

I presume they push up the Bit Rate?

Why? SD has an exact 1:1 correspondence between the scan lines in the
original analogue source and the number of pixels on the vertical axis in
the digital TV signal - 576 (well, in the case of analogue, 574 full lines
and a half-line at the top and one at the bottom). HD on the other hand
doesn't have twice that resolution - most HD broadcasts at 1080i. So there
would have to be interpolation as the picture was upscaled, which (certainly
when I've done it on still photos in Paint Shop Pro or Photoshop) leads (at
worst) to a bit of softening of the picture and at best is the same but not
sharper.

Or is it because the loss factor in the lossy compression is less for HD so
you get fewer compression artefacts?

He said it would look better, he didn't specifically say the
resolution would be improved. He might have been referring to motion
artifacts.

It does occur to me that with non-aligned scanning of an SD telecine, then
you would expect an HD scan to look a little better than an SD scan,
because although you obviously couldn't get better than SD resolution, the
SD-scan would end up at something like half-SD resolution.

I believe that there's a technology that can detect the position of the
lines in the telecined frames and can thus generate a somewhat better
digital transfer. I believe that this was used to create a few Doctor Who
transfers, but since the company that developed it charged extra for the
transfer service, the BBC went back to the usual blurry non-aligned
telecine scanning after that.

because their upscaler is better than the one in your tv - that and the
better bitrate.
