Digital retuning

I have to go out to the MILs on Wednesday to retune their digibox as
there has been adverts for about a week now that the boxes will need
retuning (we know nought of this as we get cable telly). Is this tuning
just adding more channels, or are the same frequencies being used so
channels will be there they will just be in different places or is it a
case of everything will be moved and the telly will just be a doorstop
until it is re-tuned?
Edinburgh area. MILs digibox is in the telly if that is significant.

No. It's actually to remove channels including an entire multiplex and
reduce the picture quality of what remains from the looks of it.

I think the BBC are switching over to 64 QAM and everything is being moved
so only a retune will work and most of the BBC interactive channels, if not
all of them will be removed in order to provide for a substandard HD service
on one multiplex that nobody can receive because the boxes haven't even been
built yet, and which uses a lower bitrate than SD on DVD.

Without a re-tune, she wouldn't be able to pick up
Five or a few of the lesser ITV channels as these are
shifting to different (though existing) frequencies.
All of the other major channels should be OK. She
might be able to pick up Five on the TVs analogue tuner.

The new Quest channel is supposed to be starting and
will need a re-tune as the present marker number is
changing. Quite a few other channels are changing
number as well, but they're not the sort that most
people would miss if they disappeared.

No, not at pre DSO sites. However BBC Radio is moving from Mux B into
the 1 Mb/s of null packets that have been on Mux 1 for some months.

BBC 4, BBC Parly and BBCi services will remain on Mux B in the preDSO
areas, and all muxes currently at 16QAM will remain so.

In pre-switchoff areas, the BBC multiplexes remain at 16-QAM.

At switchover, the BBC multiplex 1 and the Freeview licenced multiplexes
B, C, and D are changed from 16-QAM 2k to 64-QAM 8k.

So where is the bandwidth going to come from to put and BBC1, BBC2, ITV1,
Ch4, Ch5, BBC3 and BBC News all on the same multiplex then?

Larger dogs need less bandwidth to transmit than real moving pictures.
Simple.

I'm going away on business tomorrow morning (Wednesday). My wife is
really worried that she won't be able to watch TV. She saw the dire
warning as she switched on the TV before the sky box yesterday

I have told her she will just have to put up with it until I get home
on Sunday evening.

Retuning is a bit of misnomer. Its a re ordering of the existing channels as
far as I can see. Id expect some things to work, but some not and some in
the wrong places depending on how the box is designed.

Ahem, there is no way they will go to the new mode of transmission till the
signal levels are up to a better standard in the non switched over regions.
Just to clarify, at least according to people who tell me they know.. I'm
not naming them....
