HD Picture; All or Nothing?

[Guest]

I always assumed that once a TV receives a HD picture and there is no
breakup, that there is no way of improving the picture . Is that true,
or are there gradations with HD quality depending on signal strength,
etc?

On HD Picture 'reception', I see 6 categories of reception:

Nice Superb picture
Picture Pixelation
Picture freeze up
Picture hunting... Picture comes & goes (When big truck
drives by) I believe is temporary multipath
White blank picture (Picture present buy not viewable)
Black blank picture (No Picture present, not viewable)

Once you have a signal that delivers the bits error free the picture
quality is independent of the signal strength. Zeros and ones don't get
"better" when they are louder.

That doesn't mean that all HDTVs have the same quality picture.

It depends more on broadcast quality and the quality of your set. Since
you're probably not changing your set every five minutes, any differences
you're seeing are probably broadcast quality. About the only thing that
weak signal will cause is some pixelation (over a small range of signal
strengths below which it drops out altogether).

As other have said, signal stength is meaningless once you're getting
an HD picture with pixelation. However, depending on your TV, you may
notice a better picture once the TV has warmed up sufficiently,
because you SHOULD have calibrated your TV when it was warm.
