Hi,

I'm on Astra 19.2 and tested the following HD transponders : Anixe HD Arte HD Astra HD+

first test results :

Arte HD tunes ok and plays fine.

Same here. Arte HD is a DVB-S2 transponder using the 8PSK modulation. Locking goes without any problems at all.

...

On Astra HD+ and Anixe HD im getting an error :

Astra HD+ en Anixe HD is on a DVB-S2 transponder which is using a QPSK modulation.

If you need further informations let me know.

I tested other DVB-S2 transponders which have a QPSK modulation. All these didn't want to lock and gave a timeout. DVB-S2 Transponders with a 8PSK modulation did gave a lock (Hotbird has a couple, while I don't have subscriptions to chose channels, I'm able to lock those).

So my first impression was, it's a missing parameter in the Frontend struct. So I made some changes and check if the transponder is DVB-S2 and added parameters for DTV_PILOT (with data PILOT_AUTO) and when QPSK is used with DVB-S2, to use the NBC_QPSK modulation (which is needed for DVB-S2 if I'm not mistaken) instead of regular QPSK.

However, didn't bring me the sollution I hoped for. I now have a timeout, lost lock and regain lock, etc, etc, etc. But it's more then it was before.

So I'm close. Currently I do have a small problem where I put in parameters which shouldn't been given (oops!) and now my DVB-card doesn't lock any more, I need to reboot first.

I hope to start to work on it this further when I'm done with work. I'll keep you all posted :)

BTW, I did manage to get DVB-T working. At least it locks on on the encrypted channels, but I didn't had time to check for image. Mainly since DVB-T is my backup for channel-viewing and I wanted to focus on the DVB-S2 problem.

May I ask you, Niels or Edgar, would you try szap-s2 with parameter -M3, wh= ich=20 means NBC_QPSK modulation. It is interesting for me, whether it works. i'm= =20 not able to receive Astra HD+ and Anixe HD.

I will test it.

For your information, when I fixed up Manu's szap hack renaming it szap2 i had to add a whole bunch of options which were originally known as `team' then they eventually became known later as `meow'

These are all necessary for the hvr-4000 with the cx24116 which is a dumb part.

These params were:

-m : modulation 0=QPSK (DVB-S) 1=NBC-QPSK (DVB-S2) 2=NBC-8PSK (DVB-S2) -e : fec 0=NONE 1=1/2 2=2/3 3=3/4 4=4/5 5=5/6 6=6/7 8=8/9 9=9/10 10=3/5 11=AUTO -o : rolloff 0=0.20 1=0.25 2=0.35 -w : pilot 0=OFF 1=ON 2=AUTO

The cx24116 can't do auto-detect from what we know for any DVB-S2 parameter not only modulation. I had to emulate auto-pilot in the demod. rolloff seems superfluous in most cases but even then you must have an option to allow it.

I will check your szap but raise the point above if not all these options are catered for. If they are catered for and not named MEOW then I will be disappointed, but will survive ;-)

Suddenly, pilot not implemented :-( I get parameters from VDR(with part of source code, with perspective put it back modified), think it is familiar for VDR users -S : delivery system type DVB-S=0, DVB-S2=1 -M : modulation 1=BPSK 2=QPSK 3=NBC-QPSK(for DVB-S2) 5=8PSK -C : fec 0=NONE 12=1/2 23=2/3 34=3/4 35=3/5 45=4/5 56=5/6 67=6/7 89=8/9 910=9/10 999=AUTO -O : rolloff 35=0.35 25=0.25 20=0.20 0=UNKNOWN So, szap-s2 can handle channels.conf line like this(though not compatible with VDR, but similar): poverkhnost:12111:lC34M5O0S1:0:27500:1201:1301:3201

It is not like I'm pretend on copyright here, I can easily remove my name from sources. I pretend to be useful. Welcome any other comments. Now it is valuable like gold.

l8r!
