I've 2 perfectly good analogue TVs which I see no point in ditching in
favour of some digital TV. The impetus for me, to get a free to air digibox,
was a TV channel was going to do a long feature on a recent artist Constable
exhibition. That low power channel , locally, on analogue is just snow with
a hint of colour.
The digitally decoded version of that channel, at first sight, was full
colour and no snow. But viewing closeups of Constable's work in that
programme and of course all the other digital channels the same shortcomings
in the coding/decoding of the video info. In artistic terms I belive its
called "local colour" , in effect, a restricted palette range of colour.
Instead of a myriad of green hues you could expect from the analogue system
there was such limiting of range that it makes watching anything other than
cartoons very noticeably degraded.

Congratulations ! You've just discovered the great myth of the 'perfect'
digital picture ...

Digital terrestrial TV is NOT about better pictures or more channel choice,
it is primarily about ways to reduce spectrum useage so that this rotten
government have got more to sell off to the mobile phone operators.
Satellite, on the other hand, is a whole different matter. There is plenty
of bandwidth available there, so very high quality transmissions can take
place.

If you want to see REALLY bad digital artifacts, go look at a Freeview box,
connected to a plasma or LCD TV. Digital + digital = ( crap ) x 2 ...

Just *this* government? IMHO, the rot really set in in UK TV after the
last lot auctioned off the ITV franchises - thus setting the precedent
that revenue raising was more important than the quality of the service.
Just about everything else led on from there.

'Can' being the operative word. Most of what I've seen is equally as bad.

I agree. Time Warner's digital cable has to deliver not only the bandwidth
for regular and HD TV but VoIP and high speed internet up top 4mbps. My
girlfriend has cable, I have DirecTV we both have big screen teles. The
video compression is very noticable on hers whereas on mine it's hardly
noticable if at all. The artifacts on cable are much larger and ragged
while on sat they are smooth and gradient.

It's not all about broadcast spectrum. It's about DVD recorders, VCR's and
Hollywood's money. The entire switch to digital broadcasting has been pushed
by Hollywood so that we have to BUY all our video. HDCP "Broadcast Flag"
anyone? No you can't record HD content, because they want to sell it to you.
That's what the push for digital is about right there. Analog they can't
control copying. Digital they THINK they can. They are trampling over our
Fair Use rights roughshod. To make a back up of a DVD for a kid so your kid
won't scratch the original to pieces is illegal in the US now due to the
DMCA, and so will be making a tape of that HBO broadcast if you have to
crack the copyright protection.
Do a little research. It's all about greedy *******s wanting to take more of
your money.

Good question . In my eyes a decent picture is just fine . I do alot of
`off air`` watching with a good old pull up antenna on the tv set . If
the picture is slightly snowy i dont care , i grew up with that .
A nice clear picture is nice too .

I could care less about digital high def tv pictures .. its just not
that important .

It`s not all about broadcast spectrum. It's about DVD recorders, VCR's

Why did they make these units record in the first place ? In the 60`s
and 70`s we didnt have these . None of our friends had them . We were
out playing after an hour of morning cartoons . Parents were only
watching tv for a couple hours in the evening .
If they make watching tv hard enough it might be a good thing !

BRAVO KEN! You hit the nail on the head. No wonder this world (more-so the
U.S.) is as it is. Too much arm chair excersize.

When we were kids, we couldn't wait to go outside! Unless it was raining -
then it may have been a bit of a rant. I spent more time playing pick up
sports, fishing, roaming the local woods or creeks for critters, looking for
and doing odd jobs to earn some cash, doing errands for my parents - than
watching TV. If I wasn't doing that, then I was reading books to "learn"
from.

Yes, it IS nice to have a nice clear picture - BUT - as a recent commercial
uses the words of a famous song and says - "you can't always get what you
want". Hey, TV is TV. Cable or rabbit ears - you turn it on - watch what you
want - and get away from it afterwards! It wasn't designed to be stuck
watching it 24/7 - unless of course - you have no choice. I don't know many
who do NOT have a choice.

Today, I seen a preview of a show designed to pay big stakes for "Video
Games". Sheesh, no wonder this country is getting so freaking lazy. So it
now gives our kids more incentive to "sit" and watch a "screen". YIKES!

Technology is great but can also be ruination and at the rate we're going -
the others will create the ruination for us. They produce these stupid
things - our people get sucked into it and whalah! They'll catch us
literally by the seat of our pants being most will be sitting - and
watching - A SCREEN!

What a waste to let life slip by like that. MY only use of TV - is to watch
as I fall asleep, watch the news during lunch or dinner, "listening" to it
while busy on the computer with my work or watch during a break or folding
laundry on my couch (being a bachelor). But it sure doesn't rule my life!
Black and white, snow or clear - as long as I can see "something" - I'm
happy. IF all I could watch, is the news - that is ok. Most of the new crap
isn't worth watching - anyway.
