WHERE ARE the uhd 4k f1 feed?
and elfeed of the mux with different cameras?
Eurovision publicizes these feed, in addition to the main feed, but nobody publishes them. Eurovision says it is not standard modulation DVB-S2. the modulation is NS3 (I don't know)
Does anyone have more info about these feed?

Hello, as you know, I have been withdrawing from the sat world for some time, and now, on my return I see many new features that escape me. for example the new modulation NS3 vs dvb-s2.
Looking for the F1 UHD feed, I see that Eurovision reports that these feed sends them in this new modulation. This may be why I do not see information about this feed in any of the usual feed pages, as well as the MUX of the race with the different cameras.
can it be for this?
@Romant or the transport analysis specialists:
Can you shed some light on NS3?
