na2ts and ni2na tools

[lars18th]

Hi @piratfm ,

Can you please add also a tool na2ts to the "eti-tools"?

The objective is have the tools to encapsulate/deencapsulate an ETI-NA bitstream inside an MPEG-TS.

You agree? 😄

Hi @piratfm ,

In order to do the reverse way (that is, from an ETI-NI generate an MPEG-TS with the DAB bitstream encapsulated), a tool like ni2na will also be needed.
You feel that this can be developed?

I wait for your response.

Sorry, I don't see sense to make such apps. We are not a sat broadcasters. But patches are welcome!
Just note that ni2na - is little bit complex, but na2ts can be implemented easier (if You need to produce just a single-pid TS-stream).

I also think, a professional solution is more reliable

The objective it's create simple streaming wrappers of the DAB bitstream for opensource tools. Then, will be possible to decouple the demodulator (aka SDR processor) from the decoder (aka DAB player). As the MPEG-TS is easy to stream.

Me, too. I'm just an hobbyst! 😄

I know. The na2ts can be easy... even when creating a "pid-valid stream" (not just 0x47 header plus 188 bytes of paylod, but a valid header with CC counter and PID number).

But regarding the ni2na I'm not sure. It will be possible to generate a "fake" or "simple" mode of ETI-NA?

I created a PR for the tool "na2ts": #19

My next objectives:

• improve the new "na2ts" tool with "ETI-NI" input and PCR handle.
• improve the "ts2na" tool with new functions (auto "-s", etc.)
• develop one "ni2na" tool (in the future, as it's a lot more complex tool).

Hi,

I like to see comments about the new "na2ts" tools. Any comment?

[maceyldn]

na2ts does not need contain a valid PCR. It is just a data stream, so long as it contains a valid dab-mux should be fine.

Would like to see ni2na, eventually develop this as an output for ODR-DabMux as a fork.

@lars18th

After two years, is there a progress in your objectives? ni2na?

But I guess we can close this issue as eti2zmq might work for you as well.

Hi @andimik ,

Sorry, no time to work on this project. 😢
