All I can tell you is that when our nature/history channel switches from
720 to 1080 the jump in picture quality is nothing short of stunning.
But as I said the price for that performance is that it cuts out when
the Fedex freighter lumbers into Mather. And it's 10 minutes from here
to touch-down, all smack dab in the path. OTOH next Tuesday that same
freighter will bring the bare boards from the design I just finished.

I am glad I am not in ammericca.

Huh? It's great out here.

When I hear the freighter roar by I go to the Fedex site an hour later
and whoopdidou, I know whether the PCBs made it or not. That tells me

Members only, not good.

It all depends on how you dealt with money in the past. People who live
at the edge of financial sanity will get less credit, and that's how it
should be since credit is what go them into the mess. If you lived
frugally you'll have no problems, nothing will likely change for you.

Example yesterday on TV: Woman chained herself to their house. Banks
want to foreclose on it. She moaned and complained about "those mean
banks". Then, the reporters found out some details: This family had
refinanced the house at every opportunity, sucking more and ever more
money out of it until they had racked up $770000 (!). They had used
their house like a cash cow until nothing could be squeezed out anymore.
Sorry, but I don't quite understand that sort of behavior.

What you mention under drawbacks (artefacts), that's where we usually
start in ultrasound. And every single time we pretty much stop where we
run out of multipliers or other resources.

Yes a brick wall filter against the unwanted components has the effect
of creating a convolution in real space with an approximation of the
sinc function. This generates unwanted ringing artefacts. Hence nasty
negatives and out of bound values in the IFT. Downsampling necessarily
has to compromise some high frequency response to avoid generating
visible spurious features on sharp edges. You have to choose carefully
for optimum visual results.

You have to compromise and grade the high frequency response down a
bit.
Gaussian weighting exp(-k(u^2+v^2)) is a popular choice for a suitable
value of k although there are better functions.

I do not recommend to use this scaler, but an other one:

That is certainly true. I don't find any of the current 50Hz sets
acceptable at all for fast moving sports events. The worst thing I
have seen in shops was water skiing on a dark pond in bright sunlight.
The sets for the most part could not handle high contrast fast dynamic
changes at all and the spray pixellated in a visually offensive
manner. It is not for nothing that all the demo CDs and feeds in shops
are smooth panning of detailed scenes to show off the system
performance to maximum advantage.

I bought a set with the 100Hz frame rate which uses more processing
power but gives a much smoother image.

Amusingly last night for about the last 15 minutes the UK's flagship
BBC1 programme (in my neck of the woods) was broadcast on DTV with a
random soundtrack that appeared to be a live ambience mike at some
football match. The bad soundtrack continued into the adverts
(trailers since BBC officially doesn't have adverts). This was a
little odd since the programme was about the reintroduction of the
doormouse (subtitles were OK).

DTV continuity announcer wants shooting - in the good old days they
would only broadcast a few seconds or tens of seconds of junk on a
major channel before someone stepped in. In these digital days it is
assumed to work until the phones start ringing with complaints. The
analogue BBC1 broadcast was fine it was only their super new DTV
signal that was screwed to blazes. No mention of it after the
programme and no apology either.

Be interested to know if the fault was national or some local cock up
in the NE.
