Digital TV: Why do we have to have it?

Re antenna the difference in noise and clarity has nothing to do with that
but is simply a function of analogue TV.

Actually it has a lot to do with it. A good antenna and feeder system will
eliminate the pixellation that a lot of people are suffering now as a result
of going to digital with a far less than adequate setup. Many people trade
analogue noise and ghosting for dramatic picture breakups or even worse, a
complete loss of picture with digital. They think that buying a digital STB
will eliminate the problems they had on analogue when often they're just
trading one set of problems for another. Instead, a better antenna system
with properly terminated cables and an antenna better suited to their
location and possibly adding a masthead amp will fix most problems and give
them a superior picture on analogue and no pixellation on digital, if they
still want to go to digital. All that is usually a lot cheaper than buying a
new TV and STB.

No it doesn't. It means that analogue is not as good as digital, by a long
way.
Everything is magnified in such a large picture.
Om our normal 68 cm TV there is no difference between the two pictures. Of
one thing you can be certain, it is not due to any projector processing!

I agree with Nicholas. A decent antenna system makes a world of difference

to analogue and provides a quite respectable picture on a large TV.

All that means is that your projector does a crap job of converting from
analogue to digital. It doesn't prove anything either way about analogue
or digital TV.

Have you ever looked at an LCD when it's running in less than its native
resolution (yuck!)? I bet you get similar problems with this.

Sure, but even with the best antenna system you still get noise on analogue. And
it you put too much signal into your analogue TV receiver you get crosmodulation.

The whole point is that digital IS better than analogue.
But it is only really effective on a large screen.

Of course you can be limited by the bitrate (and hence number of pixels) from
the source.
But thankfully in Oz they have chosen to send the maximum bitrate.
As for the projector, a picture with less than the 1920 x 1080 looks better on
this screen than the same picture on a lower resolution projector.
For example, it has been compared with most of the SVGA projectors available in
OZ and is far superior - because the pixels are just not evident, even at that
lower resolution of 800 x 600 (with either a DVD or SD TV as the source). Why?
Well it seems that the edges of the pixels (from the source) are softened by the
processor. This is independant of using component or DVI connection.

It seems that only people who have not had this big quality screen experience
argue about analogue versus digital - obviously because they have opinions but
not facts.

I was comparing the excellent analogue and good digital. Obviously when you have
sufficient signal from the antenna you can make a valid comparison but not
otherwise.

Of all of the hundreds (probably thousands) of places that I have been to, very
few had a need to change their antenna or cables. Most of the problem is that
peoples expectations (from what they have been told) are different to that which
can actually be provided.
