Low Signal Quality
 

I've just had sky installed, I find my picture quality is rather pixelated
and disappointing. I noticed in "signal test" my signal quality is about
40% even though my signal strength is usually about 80%. I asked my friend
to check his and he has about 80% for both signal strength and quality.

What can I do to try and improve my signal quality? Will something such as
tweaking my dishes alignment help?

Any help much appreciated.


Thanks,

Allan

Get the installer back to do the job properly.

Kick Sky's ass to return & align your dish properly!

Well it depends,
It might be a poor signal issue or, like me you might be disappointed with
the picture quality on some channels due to the transponders being
overstuffed with highly compressed services.
You might have assumed that that BBC1 or your local ITV1 reason might escape
this given their popularity, but you would be wrong. I notice the picture
'falling apart' during rapid camera pans and scene transitions (especially
rapid fades to black) If you too notice these things then I am afraid no
amount of signal increase will improve the situation.

Maybe HDTV TV will fair better in this regard?
I think the accountants who make these decisions will always put profit
before quality.

I've already had hell trying to get them to honour their promotional offer,
now this. I thought the dish couldn't see much of the sky where it is
(between houses, pointing at next doors wall and the roof of the house
across the street) but the installer said it was fine. I'm even wondering
if they will have to relocate the dish. Surely high up on the front of my
house would be better for a nice clear field of view?

Don't rely too much on the signal readings from the box, they are a little
arbitrary in that they vary depending on the type of box and LNB.

I hope my earlier comments on the more subtle picture imperfections with
Digital TV did not cloud the issue (could be a pun there).

If your picture is breaking up into obvious blocks probably accompanied by
glitches in the sound; even if it is only doing it once or twice a day, then
you should get the installers back to sort it out.

The remedy may indeed be to re-site the dish.

After a 52 minute phone call (most on hold) I have an engineer booked for
Wednesday 8th Dec (very quick!) to investigate the matter and possibly move
the dish to the front of the house like all the others on my side of the
street.

My pictures does not got out totally, it is more of a constant
pixelation/roughness, not unwatchable but really annoying when the old
analogue BBC picture is a better. I explained all this to them and they
took me through several settings and digibox restarts but it was still the
same every time, so they booked the tech.

Allan, I suspected this when I read your original post, but after carefully
reading the above I am again of the opinion that you might not have signal
problems.

When you speak of 'constant pixelation/roughness' I think you are
describing a'texture' to the picture rather than the solid colours you
expect. And you don't appear have any issues with the sound; as the sound is
intimately linked with the picture sharing the same data stream, you would
expect some sound break-up if the signal was to blame.

How is the box connected to the TV? SCART cable I hope.
Make sure that it is the TV SCART socket that is connected to the TV, not
the one marked VCR.
In Services - Picture settings set the output to RGB not PAL
When switching from PAL to RGB and you should see a dramatic change in
picture quality. If you do not, try a different SCART socket on your TV as
many TV.s only support RGB on one (usually AV1)

Thanks for those pointers, I went through those steps the first time I used
it after install last Friday. I have it connected to AV1 (RGB enabled on my
TV set) with RGB enabled on digibox, there was a great difference when I
selected RGB on the first day. The blockyness has always been there
especially on fast motion video or running water for example. On still video
I have sort of fuzzy edge artefacts like a badly compressed JPG image.

I just don't get why I get this quality when my friends is almost crystal
clear on a bigger screen. He has a Panasonic dsb31 digibox and near full
signal & quality readings for what its worth. I have the newish Thomson
dsi4212 box. Could differences in picture quality be down to the choice of
box maybe?

This is not a signal problem. This is a DSP (digital signal
processing) problem.

Signal problems result in big fixed squares, picture jerks and nasty
glitches in the sound.
