RAI DAB+ feed from 5 West

[newspaperman]

yes, that's possible in BBFrame mode.

Here's a quick video of the Salisbury mux decoded from 10°E with the tools already mentioned just this afternoon -

...

I've joined the Salisbury "Club" too

 

[satesco]

I don't know the command line other users use to activate the DBA Rai radio on MIS 11 at 5.0W, but the one with the GOLD code and PLS 131070 (established on various sites) doesn't work in my case. Instead, if I use ROOT and 16416, everything works fine.
So instead of this line, which does not work:
dvblast -s 35291000 -v 13 -f 11013000 -m psk_8 -3 -a 0 --multistream-id-is-id 11 -u --multistream-id-pls-mode GOLD --multistream-id-pls-code 131070 | dd if=/dev/stdin skip=188 | ts2na -p 1000 -s 0 | na2ni | dablin_gtk -LI use
I use the following, and the stream runs fine:
dvblast -s 35291000 -v 13 -f 11013000 -m psk_8 -3 -a 0 --multistream-id-is-id 11 -u --multistream-id-pls-mode ROOT --multistream-id-pls-code 16416 | dd if=/dev/stdin skip=188 | ts2na -p 1000 -s 0 | na2ni | dablin_gtk -LI use

 

[EnoSat]

e2 has a similar problem, even if ROOT is defined,

<transponder frequency="11179000" symbol_rate="35295000" polarization="1" fec_inner="2" system="1" modulation="2" is_id="4" pls_mode="0" pls_code="16416"/>

e2 only works with mode GOLD

[eDVBFrontend0] prepare_sat System 1 Freq 11179000 Pol 1 SR 35295000 INV 2 FEC 2 orbpos 3550 system 1 modulation 2 pilot 2, rolloff 0, is_id 4, pls_mode 1, pls_code 131070, t2mi_plp_id -1 t2mi_pid 4096

if GOLD is defined

<transponder frequency="11016000" symbol_rate="35295000" polarization="0" fec_inner="2" system="1" modulation="2" is_id="9" pls_mode="1" pls_code="131070"/>

so the GOLD value is processed

[eDVBFrontend0] prepare_sat System 1 Freq 11016000 Pol 0 SR 35295000 INV 2 FEC 2 orbpos 3550 system 1 modulation 2 pilot 2, rolloff 0, is_id 9, pls_mode 1, pls_code 131070, t2mi_plp_id -1 t2mi_pid 4096

the value 16414 is not processed, but recalculated - maybe dvblast with the calculated value 131070 has a similar problem

or you must enter all four values --multistream-id

--multistream-id            Set stream ID (0-2147483648, default: 0)." );
--multistream-id-pls-mode   Set multistream PLS mode (ROOT, GOLD, COMBO, default: ROOT)" );
--multistream-id-pls-code   Set multistream PLS code (0-262143, default: 0)" );
--multistream-id-is-id      Set multistream IS id (0-255, default: 0)" );

 

[EnoSat]

have you tried other transponders?
Root-8/Gold-262140
Root-143816/Gold-121212
Root-175803/Gold-51416

 

[satesco]

No problems with other MIS transponders at 5.0W, but only with stream 11 on this DAB Rai Radio mux.
I don't know why only Root and old PLS work on this stream and why it doesn't recognize GOLD.

 

[EnoSat]

and the debug output for GOLD, what does it output?

 

[Satfaca]

Quick guide:
FTP all the files in the zip (except libfec.so) to \usr\bin and give permission 755
FTP libfec.so in \usr\lib
Copy "dabstreamer" from satdreamgr image ( \etc\init.d\dabstreamer ) and FTP to \etc\init.d give permission 755 (this is necessary if you want to store the DAB stations like normal channels... see HERE )

At this point you can reboot and all will work.

After rebooting you can start the deamon with the command "/etc/init.d/./dabstreamer start" (using telnet)

I have recently installed OpenATV 7.2 in the Multiboot Slot 2; followed all the same procedures as in OpenATV 6.4 but unable execute the start command (Error message:required file not found). The dabstreamer file confirmed in \etc\init.d with 755 permission. Any idea where the hack is?
Anyone with the OpenATV 7.2 here having the DAB running?

 

[EnoSat]

are all the files needed for dastreamer available + wget command?

cmd = "wget http://127.0.0.1:8001/%s -q -O- | tsniv2ni %s | ni2out --sid %s" % (sref, pid, sid)
cmd = "wget http://127.0.0.1:8001/%s -q -O- | ts2na -p %s -s %s | na2ni | ni2out --sid %s" % (sref, pid, ofst, sid)
cmd = "wget http://127.0.0.1:8001/%s -q -O- | ts2na -p %s -s %s | ni2out --sid %s" % (sref, pid, ofst, sid)
cmd = "wget http://127.0.0.1:8001/%s -q -O- | fedi2eti %s %s %s | ni2out --sid %s" % (sref, pid, ip, port, sid)
cmd = "wget http://127.0.0.1:8001/%s -q -O- | %s %s %s %s" % (sref, tool, pid, ip, port)
cmd = "wget http://127.0.0.1:8001/%s -q -O- | dvb-ip-mpe2ts -i - -o - -p %s -a %s -n %s 2>/dev/null" % (sref, pid, ip, port)
cmd = "wget http://127.0.0.1:8001/%s -q -O- | mpe2ts-arm -i - -o - -p %s -a %s -n %s 2>/dev/null" % (sref, pid, ip, port)
cmd = "dab-rtlsdr-sdgradio-pcm -C %s -G %s -S %s | ffmpeg -f s16le -channels 2 -r 48000 -i pipe:0 -f wav pipe:1" % (channel, gain, program)

or it will be necessary to modify the dabstreamer script for use in python3

 

[Dggrr]

Dabstreamer seems to be fine on python 3.10.9 on my Gentoo desktop -

~/src/dabstreamer $ python
Python 3.10.9 (main, Dec 8 2022, 07:45:45) [GCC 12.2.1 20221203] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>>
~/src/dabstreamer $ ./dabstreamer manualstart
Tue Jan 17 22:04:15 2023 Server Starts - :5237

I see the same output on my OpenATV 7.1 which is python 3.10.4

 

[Satfaca]

I don't know what to do with these commands, EnoSat.
All the files are where they should be, same as with OpenATV 6.4 , the only difference is that when I look into var/run there's the dabstreamer.pid file in it while it is missing in the same folder of OpenATV 7.2. I have even tried to copy if from 6.4 to 7.2 but after reboot it's gone again.

 

[humaxboy1]

Satfaca - it i very simple. All versions of dabstreamer are compiled for use in python2, which is used in 6.4 OpenATV. Ali version > OpenATV 7 are using python3 and it should be compiled again for use with python3. That's why i am still on 6.4 version and waiting for somebody to do that...

 

[Dggrr]

Python is an interpreted language, it is not compiled.

Dabstreamer works fine on Python 3, in my experience.

The eti-tools, that are called by dabstreamer, are compiled and so may have library version mismatches and other issues on each image version.

 

[satesco]

It's FTA on the BFBS transponder (10°E 11221V). Only the Salisbury one is present - BFBS is the operator, and I guess it just ended up being cheaper for them to use their own satellite capacity for distribution to the transmitter(s) than a web or microwave link.

By chance, I got an up to date list of the services a couple of days ago, it's much more packed out now
...

This mux for DAB Salisbury (on 11221 V) has changed its port, as it is now 2048 and not 4000, which it was until recently.
Pid 701 has remained the same, as shown in the screenshot.
Instead of tuner-s2, this time I used neumoDVB. Also, this DAB works with all the cards I have.
Here is the list of streams I have found now. Sort of an update, if you will.

[EnoSat]

I noticed on the French DAB transponder a new pid appeared.
PID501 seems to carry someting similar to PID 301 (french DAB )
It's transmitted on 239.0.1.10 port 7010 but doesn't work with fedi2eti.

View attachment 144071

Could someone with much more skills than me (@Adam792 maybe.. ) take a look?

Thanks

11456 H
- MPX RTL2 - pid 521 239.10.1.10 port 7010
11461 H
- M1 - pid 301 239.0.1.11 port 5001
- M2 - pid 301 239.0.1.12 port 5002
- RTL2 MPX - pid 501 239.10.1.10 port 7010
- MPX RTL2 - pid 521 239.10.1.10 port 7010

fedi2eti doesn't even list names for MPX

 

[Adam792]

The MPX ones aren’t DAB unfortunately so they won’t work with these tools. MPX refers to the multiplexed audio format used for FM transmitters where you have mono plus L-R with all the carrier signals already inserted (stereo pilot at 19kHz, RDS at 57kHz). I think they must be using some kind of proprietary codec inside these IP streams labelled “MPX” to carry this as a high sample rate digital stream.

 

[EnoSat]

yes, as you wrote Jul 23, 2022
rather, it was just a statement that nothing changed even after starting the new transponder 11456H

PS: but I lost 11465H (Alouette), maybe someone with SDR can check what frequencies are still active

Ahh I’d forgotten about that message!

I should get a chance to check it with SDR tomorrow.

11465 H is active; nothing has changed on this mux.

can someone please capture one of those mpx streams please? I think I know how you can at least hear something
