Currently, there is a small confusion. Most drivers in kernel, just 
report some
crap as signal strength, snr etc.

For the STB0899, STM helped so much, alongwith i had some help from one
of the Newtec guys, we were able to get the statistics in some proper form,
currently a dBm/10 scale is used.

Since this scale is different from the in kernel existing scale of 
to a standardized one, currently this change might look a bit nonsense 
to you
as it will report different signal statistics as reported by the API.

There will be a need to add one more ioctl, where the user can request the
driver to provide the statistics in a relative scale or an absolute 
scale which
can be used for measurements too.

The result would be that and end application can display the statistics 
any other commercial STB, in a nice and beautiful way, while being quite
accurate (depending on the driver) without any hacks or workarounds to be \
done in the application

(The statistics that you get is very much device specific and not device 
and hence is not very easy for a user application to get proper 
statistics as of now)

With the change, all statistics related operations can be implemented 
within the driver
such that the user is presented with standard and uniform statistics 
across multiple
devices without the need to do device specific code as done by MythTV 
etc, where it
looks for specific device drivers (really ugly)

The statistics is working with the STB0899, maybe i didn't follow what 
exactly you are
looking at. If you can detail a bit, it would be much more helpful. The 
STB0899 supports
TT S2 3200, KNC1 DVB-S2+, KNC1 DVB-S2, Pinnacle PCTV 450e and the 
VP-1041 as of
now and the same signal related stuff is applicable to all.

Currently, the STB0899 is _not_ calibrated for actual statistics. I have 
Azurewave for some sample devices to be sent to STM for proper 
calibration of the
LUT's for the statistics. (Most probably, tomorrow or so STM will 
receive the samples
at Grenoble)
