all the 'digital' hype is a bit of a con. Yes, it allows a lot of good
things like being able to cram lots more channels into the band space,
eliminating noisy pictures from a poor signal, and ghosting and so on,
and
the digital display technology allows for slimline sets, consuming less
power etc, but with the best will in the world, if we're absolutely
honest,
the displayed picture doesn't come close to a good CRT set with a good
analogue signal going in, and the same seems to be true now of film stock
versus digital cinema projection.

I hear what you're saying Arfa. bit do the displays you mention really
consume less power'? In the case of the plasma sets in particular
you'd have to go back to the early 70s valve colour tvs to find
anything approaching their wattage consumption! so much for progress
and ecology. instead of ranting on about not leaving sets on standby,
they should bring in laws against this modern cr@p!

I think at least in the Uk, what has been done to broadcasting is a
disgrace. Sell everyone flat screens with awful artefacts especially
on tv reception, then use that as an excuse to phase out analogue and
also prepare the ground to sell HDTV.

Yes, you're right, the plasmas, at least, do consume a lot of power. I don't
think that the LCDs are too bad - I haven't really looked to be honest, but
I seemed to think that low power consumption was a 'selling point', although
this could be just sales hype; I suppose it depends what you're comparing it
to. I agree with what you say about broadcasting in the UK, although I think
that the whole situation is a lot more political than just phasing out
analogue in preparation for HD. The government stands to make billions
selling off spectrum space to rich users like cellphone companies, just as
soon as they can drive all the existing users off. 470 to 860 megs give or
take a bit of 70cms amateur space and a few other users between bands IV and
V, is an awful lot of spectrum to be able to put up for auction, if you can
make the new users co-exist with the originals by making it all digital ...

We are heading back for the old days of band III TV in terms of ironwork on
the roof now. We had got it down to nice neat little 10 ele yagis for the
most part. Now, in order to receive the crap digital signals - which let's
remember are, according to Monkey on the TV adverts, going to be dead easy
to receive just by plugging into a set top box - you need a 650 element
triple reverse co-phased crossed dipole anti-ghost log periodic about 6 foot
long and with a bloody great cake-cooling rack on the back ! Cost to install
? Oh, only about 180 quid ...

And let's not forget, as most people seem to have, or have not really
understood in the first place, every little portable in the kitchen,
conservatory, kids bedroom, garden shed, and every VCR, analogue DVDR, PVR
etc, is going to need yet another 30 quid STB ...
