SAT>IP DVB-T2 no channels found

[Harune]

Hi,

I'm running a Digital Devices OctopusNet SAT>IP receiver for DVB-T2 on a Panasonic TV via network. This works well for over 5 years now.

Currenty setting up a NextPVR instance. Looking at devices I got 4 DVB-T, 4 sat and 4 DVB-C devices. This is ok since all 4 tuner can receive terrestial, sat and cable signals.

Scanning a DVB-T tuner for channels reports 0 channels found. Running a scan on  OctopusNet revealed 60 channels.

Looking at the logs there are scann requests like

logs/nrecord.log:2025-11-28 11:36:56.657        [DEBUG][17]    About to scan: rtsp://192.168.178.10:554/?freq=490&msys=dvbt&bw=8&pids=0,16,17

I've got an m3u list for VLC that works. For the frequency above it contains 

rtsp://@192.168.178.10/?freq=490.000&bw=8&msys=dvbt2&plp=-1&pids=0,4368,4369,4372,4370,4371,4369
rtsp://@192.168.178.10/?freq=490.000&bw=8&msys=dvbt2&plp=-1&pids=0,4416,4417,4420,4418,4419,4417
rtsp://@192.168.178.10/?freq=490.000&bw=8&msys=dvbt2&plp=-1&pids=0,4400,4401,4404,4402,4403,4401
rtsp://@192.168.178.10/?freq=490.000&bw=8&msys=dvbt2&plp=-1&pids=0,4432,4433,4436,4434,4435,4433

Differ in pids (maybe not a problem since a scan was requested) and msys=dvbt vs msys=dvbt2

Is there any way to change the NextPVR request to msys=dvbt2 ?

Any other ideas how to get NextPVR working with OctopusNet?

Thanks!

It looks like the T2 ini that NextPVR needs doesn't match that m3u format and I am not sure there is working plp support.

Can you get more information on the frequencies scanned, checking the SAT>IP spec. this is what I see as an example used by NextPVR

rtsp://192.168.128.5/?freq=754&bw=8&msys=dvbt&tmode=2k&mtype=64qam&gi=132&fec=23&pids=0,16,50,201,301

and so transmission mode, modulation type, guard interval and FEC inner would all be necessary with the current support, assuming multiple plp value aren't involved. I understand you might not understand this so perhaps your OctopusNet device has more information. I can also see this page might have it https://de.wikipedia.org/wiki/Liste_der_...eutschland

Perhaps as a test try this scan file if you are not in Berlin (in Berlin change the 1/4 to 1/8

Code:

[[TERTYPE]
1=Germany
2=DVB-T2 Test

[DVB]
0=1
1=490000,8,T2,8k,16qam,1/4,2/3

Ideally if sub or I could access you SAT>IP tuner from the internet we might be able to help more.
