Just had a look, no signal on that frequency now. Data signal with similar parameters on 10719V 4800 3/4 MIS 171, but doesn't look to be carrying any PIDS.

Interesting! Cheers for taking a look. If they’re on there, it’s presumably some form of DVB-IP then rather than a regular transmission.

As found by @MCelliotG - Greek ERT DAB+ is being carried on Eutelsat 3.1°E 12734V (along with the ERT DVB-T feeds) -

Requires an extra tool because it uses a slightly different version of ETI (v.11) - newspaperman/tsniv2ni

Code:
adam@mediacentre:~/eti-tools$ curl -s http://127.0.0.1:9981/stream/mux/70375cf311be0e1e32556af6a71401cd?pids=1010 | ./tsniv2ni 1010 | ./ni2http --list

Apparently this is the one carrying the DAB feeds. It is DVB-GSE (IP over DVB ) though -

Satellite sources of DAB feeds · Issue #12 · piratfm/eti-tools

Carrying 6 out of the 7 NRK DAB+ multiplexes (all regions except Oslo).

Has anyone managed to discover what pids are used in the DAB packages on 23.5E? I analyze both 12641V and 12645V but cannot seem to find the pids that contain the info!
The github page claims they have read the content but doesn't state any parameters to analyze!
We have a BIG project in the way, so I'd like to know!

Both of the ones on 23.5°E are apparently not actually MPEG-TS. All the data is the DAB stream, and it simulates being TS by having a ‘fake’ TS packet header starting with 0x47. You need to just dump all the data from the transponder and run that through the DAB tools.

Can you post an analyzed report through dab tools?

I don't have a dish on 23.5E to receive them,

It's described here - Satellite sources of DAB feeds · Issue #12 · piratfm/eti-tools

Both streams from 23.5 are using 0x47 header only (it's simulating mpeg-ts by adding that byte). So DVB-cards must work in "budget" mode and pass all packets to the reception application. Also ts2na must have negative offset (as i remember -3 bytes).
You'd just pipe the raw TS from the transponder to "ts2na -s -3"

There's a little DAB player program for Linux that you can build and listen to these DAB stations on called Dablin

Opendigitalradio/dablin

Tuned to 12.5W 12518H PID 777 (DAB Italia), the Italian muxes even carry slideshow pictures!:

I still haven't found time to translate to English the DAB+ E2 implementation by SatDreamGr on Enigma2!

Could you post command in console .
I have dablin and enigma2 from Satdreamgr.
With VLC player works very well streaming, but with Dablin i cant write correct command to play from Enigma2 receiver.
Every dab mux from 4.8E, 7E, 39E, 12.5W works perfect on rececer.
But with Dabln ...no success!

There may be but I haven't seen any. I'm only aware of the Linux tools.

What's the time delay when receiving these stations compared to through a dab radio? I know DAB radio tends to be a few seconds behind compared to FM/AM because of the extra processing involved, is the delay when it's compiled and sent out on 4.8e or purely at the receiver end?

It should be slightly ahead of the signal via a DAB radio, as the DAB transmitters themselves downlink the satellite signal for transmission (and will apply a certain amount of delay to the stream synchronise the transmissions between the different transmitters using GPS).

Most is the same as before. The two Italian ensembles have moved from 5W to 9E Italy beam (along with the DTT services). The UK ones are on 9E as well as 4.8E/28.2E now (12092H).

There's a few German public ones in DVB-IP format (also work with ETI-Tools) on 7E 12572H. BR, SWR and HR.

Even if I didn't get very well the frequencies.
Anyway, I am interested in times radio, any suggestion?

On 30.0W there are some DAB muxes in DVB-IP format for the Portugese, Spanish and Catalan market.

They're not DAB, they're just standard AAC audio streams transmitted in DVB-IP. They feed the FM transmitters in Portugal, and in Spain they feed the regional studios of each of the networks where local adverts/programmes are inserted (before getting sent to the FM transmitters).

At least some of the Portuguese ones (Rádio Comercial at least) also carry the RDS data for the FM transmitters via this feed, inside the UDP packet headers in the DVB-IP stream.

I'm not really sure why they're listed as DAB on Flysat. You can use the tools that come with the satellite DAB eti-tools to decode them, so maybe that's where the confusion comes from!
