If it is indeed delivered over DVB-H, the SDP ought to be delivered by FLUTE
(RFC3926), but if it's a trial it could be SAP or something proprietary. If
over multicast, it really ought to be on a different IP address and
different port.
However, many trials have limited channels and they are eithe

DVB-H can be with IPv4.
In Italy we have three different DVB-H providers, each is using IPv4.

Do you mean that it should be hidden somewhere in my udp.dump file? But
it contains only UDP packets sent to ports 2 and 20002, and all of
them are valid RTP packets.
How to search for it? Might it be

I've no idea, especially if you want to do that on the fly. In that
case you'd probably need some kind of DVB APIs.
As for captures, a viable (if overly complex) way could be replaying
the captured traffic as if it was normal network traffic and use

Yes, I was able to dissect it with wireshark as RTP, and it shows
payload types 96 (on port 2) and 97 (on port 20002). According to

If you're on the West side of Russia you might be getting something DVB-H
from the East of Finland over DVB-T: but I very much doubt it. In Finland
most of the DVB-H trials are in the West and they'll be increasingly headed
for their own Mux and 4k mode (DVB-T receivers ought to only be capable of

Hi yall,
Been googling for a while, but my problem seems rather simple so I think
I'll just ask.
I have UDP encapsulated MPEG TS; how do I perform online analysis using
dvbsnoop? All the pages I've been to so far seem to indicate hardware is
required. This may be the case for QAM transport, but
