Hi.
Tecnically signal quality should be possible to get from eighter ber,
unc or snr. Signal level is not really important, because a low noise
floor with a weak signal could give you just as good a reception as a
strong signal with a strong noise floor. What you as an end user wants
is a
Hi Wolfgang,
the SNR value is only dependent on the demodulator you use, so even with
a different frontend, the values can be directly compared as long as you
use the same demodulator IC (and firmware, maybe...).
For most demodulators, you can give a (more or less) simple equation to
Hi.
This has given me some grey hairs a couple of times. Mentioned in
#linuxtv earlier, but this time I send a patch. Thanks for all help!

I verified that it is the problem, by watching the BER numbers from czap
go from 0 to 3 digit order when starting playback of anything on the
screen using the nvidia driver.
I have now swapped PC with an older Dell Optiplex with ATI graphichs,
and it is working fine. I didn't manage to get the
First, try differene resolutions on your monitor. It should not make a
big difference, but if it does, changing the VGA/DVI cable to DVI/VGA
or to a different of the same type could help out a bit.
I need to run at 1920x1080_50Hz on the DVI (to HDMI) to make full use
of the Monitor. All other
You wouldn't by any chance know of any good devices to amplify / clean
DVB signal befor it's fed into the DVB-card ? I tried with an ordinary
antenna amplifier , but that even made my settopbox , which normally
works fine, go bananas too .
If the Nvidia card introduces noise, it probably
Hi.
I have a question regarding the frontend. You ask for:
ioctl(Fd_frontend,FE_READ_BER, ber_value_goes_here)
As I have not seen the result from this that I would expect from the
documentation here:

this question/request
Nice idea. But i think 1Mhz is a bit heavy. Have seen an approach on a
commercial STB, where you could give the starting frequency and the
distance (f.i. 8khz) to do a scan. Shouldn't a similar approach also
work with scan ?
I've had success locking on a 27500 mux with being as much as 15MHz
I thought the MT352 is a demodulator... isn't the tuner a separate entity??
For example my cards both use a MT352 demod and they also both have a Thomson
7579 tuner so it may be that your devices both had the MT352 but
different tuners... here's what I discovered on the wiki
I am a little puzzled as to why the second entry in your example is
showing uncorrected errors and yet has a ber of 0.
Many (at least professional satellite modems) receivers calculate BER
rather than actually measuring them, and the other way around. The
theory is very clear here, and quite

Hi Samuel,
I am developing a dvb s1 transmitter. Its input is a MPEG TS from a
mpeg encoder and its output is a DVB S1 stream to the RF satellite.
OK.

What would be the common cause of transport_error_indicator to be set?
Is this set in hardware or in the driver?
I seem to get bursts of packets with the indicator set sometimes. At
some channels it comes very regularly, like every 5 second or so. It
is often accompanied by blocking and sound

I am also very interested in the state of this driver, if there is a state.
