EnoSat,
do you get picture and sound on free t2 muxes? Which applications and OS do you use?

DVB-T2 in my country planned on 2013~2014 , DVB-T work ok but level and quality show 90% , momentary use WinXP.

Hi EnoSat

The PID 8191 is the empty stream,You do not need to care about this.

Kind Regards

steven

actual situation with driver tbs5880.sys (ver-1.0.0.1) in DVB-T
signal 30dBuV show as Level-90 and Quality-90 , BLUE led , show actual pid`s in stream
signal 70dBuV show as Level-90 and Quality-90 , BLUE led , show actual pid`s in stream
signal 0 dBuV show as Level-10 and Quality-0 , RED led , but show pid 8191

[EnoSat]

status on emty transponders:
show empty (non-exist) pid 8191 + after some time show fake pids

show status signal in another SW:

Hi EnoSat

Sorry for the delay reply,About the signal quality ,we have not added the calculate of the level,
if locked the value is 90, if have not locked the value is 0,So this is why the value is always 90,
this is because DVB-T's signal is not like DVB-S.

Kind Regards

and problem with no-signal ? showing pid 8191 (thread part-2)

but cxd2820 report correct SNR, RFLevel values (strenght), so can be used for some Strength/Quality calculation.

for example my implementation in StreamREaderEx-BDA + TSReader proxy source:

Reception of DVB-T2,256QAM,3/5
Strength=SNR*2, Quality=f(BER). Maybe only RFLevel some incorrect (because i not have lookup table for AGC->RFLevel conversion)

[steven]

Hi crazycat

thank you very much for the Strength/Quality calculation, we will have a update about
this later.

Kind Regards

@crazysat: any chance crazyscan2 will support the TBS 5880 box as well?
It works well with TBS 5925.

@Thorium: wait updated drivers with I2C-access.

P.S. And maybe i need some additional info about cxd2820r (proper RFLevel calculation, constellation monitoring) - so if somebody have this info - send me to e-mail or PM
