Hello all,

in the process of replacing ZeroMQ by EDI for distribution of ETI, the
need to replace ODR-ZMQ2EDI appeared.

Some modulators only support EDI over UDP, so if you want to carry EDI
over not-so-reliable networks and want to use TCP, there's was no way
except having an ODR-ZMQ2EDI instance running close to the modulator.

I have just published ODR-EDI2EDI for that application:

https://github.com/Opendigitalradio/ODR-EDI2EDI

Cheers

Great news Matthias, this tool can help those modulators who in EDI UDP have a lot of sensitivity to network jitter and so disconnect frequently.
What do you think, could you also put a TCP output (or zmq) to feed the Sergiy modulators? Infact in zmq link with mux, with network delays greater than 20ms tend to become unstable, to the point of failing the connection sometimes (
the best thing would be Sergiy implement reception of edi on his card, but I think he has no more space in the FPGA)

Thanks a lot for this toolt!!

Hello Francesco,

I doubt I can take time to work on a tool like that, but I will not
remove the ZMQ output from ODR-DabMux anytime soon, since it's used by
the EasyDAB.

Cheers

Hello Matthias and Francesco,

actually I am working at the same problem, to put the zmq stream to Sergji's modulator via VPN Links with more than 20ms network delay. It seems to be very difficultly.

I'm thinking of putting a second muxer to the transmitter station and feed this second muxer from the first muxer via EDI. Is it possible to create an input subchannels with inputuri for EDI Input from a muxer output?

Have a nice day,
Markus

Hello Markus,

no that wouldn't fit the way ODR-DabMux works. A tool like ODR-ZMQ2EDI
or ODR-EDI2EDI would be most appropriate.

Hi, Matthias, in the future, it could be fantastic to have in this tool also a zmq output to feed Sergji modulator, so we could be indipendent from network delay greater than 20ms that create instability and disconnection.
Thanks.

Hello Matthias,
thanks for your great new software odr-edi2edi. It works good for buffering EDI streams and for converting vom tcp to udp and to multicast, I have tested a lot today.
To integrate zmq or raw (ETI over tcp) output (the output modul from odr-dabmux) it would be very very helpful to work with Sergji's modulator. It's a perfect idea.

Hello,

there is no need to do anything. This software https://github.com/piratfm/eti-tools#eti-edi2eti does it's job for this problem, too.

Which is required to operate the EasyDAB in SFN mode... very much required here in the Netherlands...

Following this thread with great interest now ;o)

Best regards,

Gerard

Hi, a zmq output in editoedi tools could be also the solution to Easydab glitch......
Do you think Matthias is possible put it in the future?
Thanks a lot.

Hello Francesco,

the problem is that nobody is taking care of software development on the
EasyDAB v2. There's something wrong with timestamps (see Gerard's
emails), there's no EDI support, and there might be other undiscovered
things.

I'm not using the EasyDAB, not because of lack of interest, but there's
just a lot of other stuff ongoing. And I can't develop something that I
can't test.

So if you want to use the EasyDAB, don't ask me, find someone who can
maintain and continue the development of the EasyDAB.

Sorry,
mpb

I've exposed the problem to Sergji a lot of time ago, he reply to me that he must prepare a mux with new release, but after this no other reply.......
