Howto set DVB-S2 information in .INI?

[nwagenaar]

I would like to watch some DVB-S2 channels on the sats I can receive (Astra 19.2e, Hotbird 13.0e, Astra 23.5e and Astra 28.2e) and in the past I read something about that the data for DVB-S2 transponders isn't 'complete'.

For instance, my provider sends out several DVB-S2 channels on Astra 23.5e (1D/3A) and I defined it as followed (I changed a current value):

22=11720,H,27500,910,S2

During scan it (obviously) failes to scan this transponder. According to kingofsat it has the following information:

Astra 1E (23.5E) - 11778.00 V - Txp: 68 - Beam: Astra 1E DVB-S2 (QPSK) - 27500 9/10 - NID:3 - TID:3204

So, the information I possibly need, is how to setup the information in the .INI's for DVB-S2 transponders. Because several use QPSK or 8PSK.

Could anybody provide me this information?

Unfortunately there is no easy answer to this. The reality is that even though the in theory supports DVB-S2 (for Hauppauge or FireDTV devices), I dont know if anyone has ever tested it. We dont have any DVB-S2 available here.

In "22=11720,H,27500,910,S2", the "S2" part needs to be replaced with a number constructed from the following bit mask:

Code:

Bit 0-1 : Modulation (0 = Auto, 1 = QPSK, 2 = 8PSK, 3 = 16QAM)
Bit 2   : Modulation System (0 = DVB-S, 1 = DVB-S2)
Bit 3-4 : Roll-Off (0 = 0.35, 1 = 0.25, 2 = 0.20, 3 = reserved)
Bit 5-6 : Spectral Inversion (0 = undefined, 1 = auto, 2 = normal, 3 = inverted)
Bit 7   : Pilot Symbols (0 = off, 1 = on).

[nwagenaar]

So, in short. We're talking a 8-bit values in the following way:

Code:

Bit 0-1 : Auto = 00 / QPSK = 01 / 8PSK = 10 / 16QAM = 11
Bit 2    : DVB-S = 0 / DVB-S2 = 1
Bit 3-4 : 0.35 = 00 / 0.25 = 01 / 0.20 = 10 / reserver = 11
Bit 5-6 : Undefined = 00 / auto = 01 / normal = 10 / inverted = 11
Bit 7    : Pilot off = 0 / Pilot On = 1

The line with values 11778.00, V, DVB-S2, QPSK, 27500 and 9/10 will become:

22=11778,V,27500,910,01100011

01 = QPSK
1 = DVB-S2
00 = 0.35
01 = auto
1 = Pilot off

Does this seem right?

[sub]

The bits go the other way (most significant bit first), so "1" "01" "00" "1" "01", or 10100101, which is binary and needs to be converted to decimal, so 10100101=165.

22=11778,V,27500,910,165

I think that something is very flaky with the support for my Hauppauge WinTV-NOVA-HD-S2 (Detected as HVR-4000). I've tried GBPVR (latest version) with the drivers van WinTV CD 4.6b (April 2008) as well as the old drivers from January 2007 and get the following output:

It seems it ignores settings thrown to the driver.

* small bump *

Anybody have a sollution? Or does anybody know which DVB-S2 card will work with HDTV channels?

Sub, if you need more information. I'm glad to give it to you

[sub]

nwagenaar, are you on Vista or XP?

[sub]

I have talked to Hauppauge about this problem this morning, but I didnt receive any solid comments about what I should do to resolve it.

[nwagenaar]

Hi Sub,

For your information. I do run Vista (32-bits). I do hope the people from Hauppauge may be able to tell you something

[nwagenaar]

Sorry to bump this old thread. But currently I'm in process of reinstalling my system because of new hardware (motherboard/cpu). But I still have the my trusty Hauppauge NOVA-HD-S2.

Currently my configuration runs a Linux configuration with VDR and XBMC. But hardware decoding of H264 transports is unstable and software decoding results in stuttering. So I'm looking into a Windows Vista installation again and I want to try the new GB-PVR version. But this will only happen if the DVB-S2 scanning will work with my DVB-S2 card.

Sub, did you hear anything from Hauppauge? And have others got the viewing and scanning of DVB-S2 transponders working?
