[linux-dvb] Picture Quality

[Alex.Wiessner@unvienna.org]

Hi !

First of all my Hauppauge card is getting rather hot as well. It's
especially on the RF (HF) area. I sure that's normal. My VDR was
continuously running for a couple of days now and I didn't get any heat
problems.

I've never had any problems with picture quality on live television. It's
probably you dish (what diameter ?) or the alignment. How is the quality of
the picture if you connect an analogue receiver ?

Hi folks,


first of all I have to thank all the programmers for their great work.
The VDR was my reason to go for Linux and dig. Sat TV. Its just a great
thing !


Since this is my first time having dig. Sat TV, I wonder about the picture
quality.
I see many mpeg based artifacts more or less on any station. Small ones
around contours with high contrast and motion related artifacts. So the
overall picture impression is quite less than with my old analog cable.
There´s only less noise.

Is that really normal, because of the relatively low data rate ? Is Sat TV
that problematic ?
Or is it due to the DVB card and its decoding ?  I saw the same problems on
some DVD players, they also had trouble decoding.  So it might be just a
decoding issue in most cases.


I got a Hauppauge (rev 1.3) which runs quite hot. A friend told me his
Technisat runs very cool.
Are there different revisions of the cards, or does it not matter ?



Or should I not make such a fuss about it ? :-)



thanks


Tobias Jachmann
