The picture on the TV has just degraded to early Five standards. This
is on terrestrial.

What is going to happen when the buggers switch us all to digital?
Total white-out?

You will see nothing but white noise.

Umm, it can't really be called white noise can it since I thought they were
going to use the same channels for digital. OK, so I'm pedantic ;-).

What some people *might* see, depending on the design of their TV sets, is a
slight increase in noise even when watching pictures from an external source.
I've noticed my TV does this unless I have an aerial plugged in and the
analogue tuner selected to a valid channel, even though I'm not watching the
analogue picture. I guess it's just slight crosstalk in the video input
switching circuitry, and to be honest on my TV it's so slight that many people
wouldn't notice and fewer would care, but it's definitely present. I keep
meaning to take the wire cutters to it. Maybe one day I will.

I take you mean as a result of "atmospherics" affecting analogue
reception?

BSOD...

As the interference increases so will the amount of blocks and frozen
frames/parts of picture until it either totally freezes or just blanks
thes creen the transition from perfect(*) to F all is quite likely to be
quite quick.

(*) I use the term with the qualification. Just come back from my sisters
down south and have been watching their Sony LCD IDTV set. The quality was
highly variable from channel to channel BBC1/2 are OK (ish) still have the
odd blocky splat and horizontally scrolling credits are so jerky/smeared
as to be unreadable (fine when static). Other channels are almost
unwatchable, ITV2 and others, terrible multiple image lag/smearing on
moving objects with fairly frequent 1/4 frame blocky splats or freezes.

Makes me glad that terrestial digital won't be here for another 5 years
and even when it is I think I'll stick with DSAT...

There was a bit of a lift on today. I was picking up several dutch
radio stations on the A14 today. And Broadland FM was bombing in.

I heard they will sell the analogue frequencies, possibly for mobile phone
use.

I think you'll find most of those artefacts you observed are more to do with
the LCD display device, and not DTT transmission per se. Feed a D-Sat version
of the same channel into the set, and it'll look much the same.

Having said that, some ITV and C4 channels do use noticeably less bandwidth on
DTT than on D-Sat. However that's offset by ITV-1 and C4 using a horz res of
704 on DTT, compared with 544 on D-Sat. Bizarrely Ofcom set a minimum
horizontal resolution of 704 for ITV1/C4/C5 on DTT, yet no lower limit for bit
rate. The other ITV/4/5 channels are a total free for all technically on all
platforms.

So, an improvement on the current output, then?
