BBC1 HD signed programmes

As far as I can see, what they do is shrink the picture so it makes room
for the signer, thus losing resolution because the programme is made in
SD. They then upscale it for HD. Why not fit the original (be it SD or
HD) into an HD picture? Then, if the original was SD it would end up
more-or-less the same resolution as it started off, instead of being
sort of 405-lines-ish. Do I make myself clear? Thought not.

Simpler solution - just rely on subtitles!

I suppose it's a cultural thing, but I would have thought the same: I have
no difficulty following the subtitles of foreign language programmes.

Yes, but as they probably send most of the stuff via sd as well would this
not mean making two versions?

Hi Bill,

Yes, but you wouldn't make the picture clear for those who haven't got HD.

The oriinal picture would look very small when the programme was
simulcast on BBC1 SD, which is what happens with BBC1.

That's not the point.

Hi Bill,

Of course not. It would make no difference either to the clarity or the
size.

It would look exactly the same as it does now in SD. But in HD the part
of the picture showing the original frame would be roughly the same
resolution as it is in SD when it is broadcast normally (filling the
frame), whereas with the present method it roughly equates to a 405-line
picture.

OK. (I think) I see what you mean. You're again suggesting that the SD
picture be postage-stamped into the HD frame. Most people wouldn't like
or understand this. Also, it's not just SD programmes which get signed,
HD programmes do too.

You make perfect sense Bill. (I should get out more!).

I assume the signing department doesn't have HD capabilities yet? Or,
if it does, they don't send the SD programmes to that part, keeping it
only for HD programmes?

They haven't really caught up with the implications of BBC One _HD_
yet - there are lots of programmes which aren't full HD, but are (or
have parts which are) better than SD - but for now, they're all SD.
It's a hang over from BBC HD's instance that HD programmes must be at
least 75% real HD - whereas, given they run BBC One HD 24/7, I think
any programme with _any_ "better than SD" content should be processed
in HD to make the most of it.

Shrunk SD is of course "better than SD" in terms of resolution, as
long as you process it in HD.

Cheers,
David.
