Has anyone got T2-MI working?

Chris G

From what I understand, it's DVB-T over satellite?
Right now, as far as TVH is concerned, these muxes only contain a single service.
The service gets disabled (parent disabled) and won't play anything.

I can create a mux dump if someone thinks they have a solution?
There are several muxes across Europe that use this standard with and without encrypted serveries.

I don't know much about it but a quick search says "T2-MI is a communication interface embedded into the second-generation digital terrestrial television signals (DVB-T2) received by the modulators that carry out the broadcasting itself. In fact, T2-MI stands for T2 Modulator Interface. The T2-MI signal provides the broadcasting parameters and contents to the modulators." so that doesn't sound like anything to do with a satellite. DVB-T is designed for terrestrial broadcast and the kind of errors that are common in that kind of broadcast,so it seems unlikely they would adapt that for satellite use, which encounters different types of error.

Maybe if you can provide some more information about what specifically you're trying to do and who the broadcaster is etc somebody will be able to help?

edit to add: a second search brought up "The term "t2-mi satellite" is a misnomer;
T2-MI (T2 Modulator Interface) is a communication interface for the DVB-T2 (Digital Video Broadcasting – Second Generation Terrestrial) standard, which is terrestrial, not satellite-based. However, some satellite receivers, labeled as DVB-S2 T2-MI, are designed to receive satellite signals that are then used to transport T2-MI streams, enabling the satellite to act as a backhaul for the terrestrial DVB-T2 system." so on the face of it it sounds likely you're trying to interface to a signal that is not designed for public use?

I really don't know what it is.
I remember reading it was T2 over DVB-S some years ago.

Here is a mux on 4.8E:

TVH reports 3 services.
1 for the "normal" channel listed at the top, and 1 for each of the T2-MI groups (is group the right term?), both T2-MI services get disabled.

If I ffprobe this mux I see:

Only with TVH I think it is not possible.
But by adding tools (such as astra-sm), it becomes possible.

A very complicated real case where it worked well after some steps:

("only" for T2-MI I suppose that most of the steps are not necessary)

Kind regards

Thanks for the reply.
That's very complicated.
I wonder if it's possible to include that "astra-sm" with TVH and have a simple checkbox on serveries which pipes the service through it?
