News MultiStream on Vu+

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 :D )

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 ....
service_info_multistream.png
Here is the screenshot about Service Info when I see an ordinary channel ...
service_info_std.png

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 ...

Skystar 2 USB is not capable to recept these channels and actually there is no support into enigma2 that support ACM modulation.
Thanks for your reply.
Can you say me what i need. SkyStar USB 2 HD is not compatible.. ok.. which one is compatible?

Thanks

Actually I discourage to buy something related to MultiStream because is a very alpha feature and I'm not sure to implement it on stock BH images.

Hardware is specified into my first post of this thread.

ok there is no chance with enigma2 receivers (for the moment). Skystar hd usb & pc it should work.?

Thanks

If you talk Multistream on DVB-S2/8PSK transponders they should work when I include MS support on enigma2 and MUST HAVE Technisat Skystar HD USB device.
If you talk about Multistream on DVB-S2/16PSK-32PSK-ACM-VCM there is no ETA and I don't know if they work or not. I've planned to buy a TBS5925 in the future (2-3 months) and try directly but I don't want to report as work-able or other strange things: I can report if they are work-able only when I can test it directly.
I hope you can understand my words and my work method.

You make a good work..

Sure. These channels are modulated with ACM so they not work with my hardware.

This not ACM. It's also 8PSK multistream with changed PLS code. You must some extend stv090x driver with PLS support (some extended bits in stream_id) and add PLS support to enigma2.
See my sources - https://bitbucket.org/CrazyCat/linu...ivers/media/dvb/frontends/stv090x.c?at=master
additional stv090x_set_pls() + extended stv090x_set_mis().
And my fork Enigma2PC - https://github.com/crazycat69/enigma2pc
Proper PLS codes for Mediaset, RAI multistreams @5W, 13E you can found in https://github.com/crazycat69/enigma2pc/blob/master/etc/tuxbox/satellites.xml

P.S. Same implementation in drivers enigma2-openpli for STi7111-based STB (aka Fulan spark)

ok..+ mi spiace davvero tanto
i love blackhole image but it need for multistream support mis/pls
Pay attention.
The Vu+ tuners NOT SUPPORT MULTISTREAM!
When the feature will be implemented in stock BH images, you need a specific hardware to tune and see multistream TPs.

Now that full support is available for the TBS5925 has the openBH team added support for this multistream capable tuner ?

Thanks

Hello everybody,

first of all I`d like to thank angelofsky1980 for his interest in multistream reception. Yes, this topic is very hot on other forums, too. Multistreams and T2-MI reception is no more a matter of hard core DXers, but also ordinary TV viewers as there are plenty of interesting FTA stations.
Anyway, I`d like to ask you, angelofsky1980 will you, please consider to add Multistream and T2-MI support to our great Black Hole image?

I hope you won`t mind if I help you with some links even I`m sure, you`re familiar with all this stuff already:

http://www.satdreamgr.com/forum/showthread.php?14001-SATELLITES-XML-7-5-2016-FOR-MULTISTREAM

Info about Astra SM (needed for T2-MI reception):
Code:
https://gitlab.com/berdyansk/astra-sm
https://gitlab.com/berdyansk/astra-sm/blob/master/src/mpegts/t2mi.c

TBS 5925 & 5980 do the job perfectly in OpenPLi and SatDreamGR images, so I hope that with your and other BH Driver specialists` help we can make it work on BH, too!

PLS are a bit tricky sometimes, so a little help from our DX community where we publish everything you`ll need:
Code:
http://satellitescommunity.de/index.php?sid=a9d951f7e00b38a0843c820c96326abe

It`s easier to change the image where everything works, but I guess we are members of this community because we love Black Hole! So let`s make it even better as it`s right now!
Thanks to all who are/will be involved in this project.

Regards
sato
