During these winter vacations I've worked around MultiStream, Vu+ and my Technisat SkyStar HD USB.
Why Technisat SkyStar HD USB? Because it has ICs and Demods capable of MultiStream for sure
This is (only) a little report about implementation status and TODO list.
Hardware used:
1x Vu+Solo 4K
1x SCR LNB mounted on my USALS rotor dish
1x Technisat SkyStar HD USB
1x BH image with MultiStream support (of course

)
First thing to do: introduce into Enigma2 all the logic about MultiStream and the corresponding commands for the DVB-S2 device (thanks
@crazycat for their implementation that I've used as a base for mine!)
Second thing to do: test enigma2 compile
Third thing to do: test, test and more test ....
After two steps succeded, the only thing I should do are the only interesting: search and tune.
First operation: check if SkyStar USB HD works with my rotor and LNB like an internal tuner and it was OK. Not so quickly to zap but works and it's a great thing. USALS control also works and preliminary tests are all positive.
Second operation: try to scan a MultiStream frequency. After some Google's search I've understood how works MS and my target is defined: Eutelsat 12 West B @ 12.5W where some streams are present and have correct modulation and less parameters to be inserted to perform scan.
I've tried to scan the following frequency:
12718 H 36510 5/6 8PSK - streams 33 to 36
Looking from enigma2 debug log, after issue the first scan command (stream 33) I've seen immediately that all C++ and python code are good and
WOW channels are found!
I've continued with other streams and now I can try to tune ....
Channels gone in the same place like all other channels ....
I've choosen RTL 102.5 channel ..... IT'S WORK!
Here is the screenshot about Service Info when I see MS channel ....

As you can see, all works properly.
I've tried also other MS frequencies but for missing tune information the scan was failed.
Other scan-able MS frequencies are located @ 4.9E but quality was unaccettable, I suppose due to signal quality and or bad reception from my USB device.
TODO list:
- check if Vu+ tuners have MULTISTREAM capabilities and, if check is negative, ask Vu+ to add them (if they can, according to hardware specs used into their tuners)
- write a list of device capable to MULTISTREAM (DVB-S2 and DVB-T2)
- test MS on DVB-T2 (not yet tested due to missing muxes in my area that uses MS and -T2)
- refine support into enigma2 to be more and more robust.
I'll evaluate in the future if I would release a MS image for some Vu+ boxes. Please, DON'T ASK FOR AN IMAGE NOW: I don't know where you live, what kind of tests you can do ... so I appreciate any kind of help: reply into this thread and explain what can you do
This is a little step forward to make Vu+ a very complete machine ...
