Re: MPEG2-TS, DVB-SI, and DVB-GSE Dissectors

Hi Alexander,

good to see you again. We worked together in the DVC-CI+ group back in
2014. I hope that I told you about Wireshark's CI+ dissector then ;-)

Thus wrote Alexander Adolf (alexander.adolf () condition-alpha com):

... and the best way to _become_ familiar with the code.

There's no such thing as a "high-level introduction to the DVB-related
functionality" document.
There is, however, doc/README.dissector, which is worth a read.

That sounds like a good starting point: Find a field that we don't
interpret correctly. Try to find out where it's defined and modify it.
Try to come up with a small and simple modification for the first patch.
If you get stuck along the way, let me know which field you're looking
at and prepare a ts file that you can share with us.

Good luck,
Martin
