Thanks for the link. Linked on that page is a doc that explains the BBCs
dolby use.

http://downloads.bbc.co.uk/rd/pubs/w...les/WHP175.pdf

So now I know that p21(17) they "generally use" mixdown params of -3dB
for both center and surround.

I have nothing to test but guess they actually send this in their dolby
stream but what about AAC on DVB-T2?

Dialogue level and drc are used but I've never seen anything mixdown
related in a stream even though it is possible, so I suppose we get
whatever the decoder does by default (-6dB surround?).

Does any one know why DVB-T2 didn't use dolby? I would have thought that
it is more compatible with existing kit, eg. if I actually had a 5.1
system my TV would pass dolby to it via s/pdif but I don't think it can
with AAC and I guess less amps would take it anyway.

I always thought the girl on the Sveridges Radio card was quite nice.

I've just looked at that white paper. That new word in the OED,
"Omnishambles" springs readily to mind. It's hard not to laugh out loud
when it gets to the Red Bee/Probel bit. If anyone bangs on about how
much better Digital is than analogue, just walk away...

As documented, I'm surprised the decoders don't just burst into flames
at every programme junction.

One can read between the lines, er, frame boundaries.

I've not yet read it. But it sounds like what I've expect from having had a
peek at the 'surround sound' used by BBC HDTV at the time of last year's
Proms! :-/

I asked various people at the BBC about mixdown, etc. They all gave
different answers for what 'standard' the BBC was using!

FWIW I've already encountered confusion between 'dolby' and the aac in
feedback I've had to magazine articles...

I *presume* the acc is to give better quality, etc. But it all adds to the
joy of 'standards' dunnit! The more, the merrier! :-)

Slainte,

I don't have the facilities, sadly: I hope someone here will capture the
"10 minute loop" and put it on YouTube, or something (the nostalgic bit
sounds interesting, even if recreated in some cases).

I agree with the various comments that say, basically, that we can't
believe they can't find a couple of minutes a day to send the test
signals.

Can you open your mind without it falling out?

Yes just remove one boring promo every day should do it.

I have a Sky HD+ box and a Panasonic Freesat HD with BD burner. The
former does not recognise the item and just says press back up to
proceed, but the second has taken the entire lump as recordable.

On Sky boxes, you need to set it as a manual recording, (same procedure as
recording radio channels)
