Blindscan multistream. Now what?

ArloG · Dec 2, 2022

Yeah. More and more blindscans are showing multistream here in the US.
Spotty information of what to do next, for real. I add them to my satellite.xml for the sat that they turned up on.
Manual scans for channels show nothing found. Encrypted or not it would be nice to get a tutorial covering A-Z on what to do next.
The Edision osmio4k is advertised as being capable and ViX seems to be playing "kind of" nice in a Lucas Electrics sort of way, although OpenATV 6.3 is my favorite image.
So what is needed to see channels on these transponders?

<transponder frequency="3839000" symbol_rate="32727000" polarization="0" fec_inner="3" system="1" modulation="1" is_id="0" pls_code="1" pls_mode="0" />
<transponder frequency="3839000" symbol_rate="32727000" polarization="0" fec_inner="3" system="1" modulation="1" is_id="1" pls_code="1" pls_mode="0" />

It will probably be necessary to upload the full TS and analyze what encapsulation is used

dvlajkovic · Dec 2, 2022

That's right. @ArloG please find someone with a PC DVB satellite tuner card that supports MIS to record at least a minute of a full TS so we can see what is packed inside.
Then upload somewhere this recorded TS file and drop here a link for us to download it.

Thanks for the suggestions. Unfortunately I may be the only one around with a working c-band setup.
If I may, to keep this all in one place. Not only pertaining to the multistream subject but also what seems to keep coming back at me when asking for assistance or a bit of a tutorial.
Tons of E2 receivers advertise being multistream capable. But does that mean without a DVB card in a pc to analyze the stream a person cannot receive video and audio or extract the correct things needed to do so?

In a recent post here I asked about recording a full .ts stream with my mio4k. Not by simply using the built in recording function but with something like dvbsnoop or an installable plugin.
Perhaps feeding the Ethernet signal to one of the DVB applications that allow sat/ip options along with being able to use one of the many DVB cards out there that they obviously are made for.
I got that partially working. But confusion and little available info. was out there to get .xml file data and lamedb imported from the mio. I believe it was DVB Viewer Pro (until the license expired).

EnoSat, you have an impressive hardware list at the end of your reply. It has been long time due for me to obtain a DVB pcie card. I have a very robust desktop pc with a more than adequate Nvidia card that I can cast to my various TV's no issues.
Forums have been little help in assisting a decision on which TBS or even a professional sat/ip DVB card.
1) I don't need 4 ports. Just one, maybe 2 will do. I need it to reliably steer my dish with diseqc protocol. And control a diseqc multi port box.
2) I'd really hate to be surprised after the initial learning curve that the card I bought doesn't do something needed for the more advanced uses of it besides watching TV.
3) IP data. For me kind of important. We have a NASA transponder here on 89W Galaxy 28 that broadcasts all sorts of data and images using multistream.
With the mio4k I have it will not do a solid signal lock. But using dbvsnoop I have been able to peek at some of the clear text data on one of the channels.
I registered with NOAA here and have a software package that uses data injection from a DVB car or one of the ip-data receivers such as the recommended International Datacasting Novra receivers. But even an older Twinhan DVB card can be used with limited functionality.
It would be cool as hell to be able to get the software functioning.

Well EnoSat. If you were to grab a TBS card, or the best card-du-jour. What would be your choice? And what about you dvlajkovic? Anything?
I'm ready. Even looked at a few rack mount DVB-S2X receivers. And one of the ones like the Viark Sat 4k units.
Sounds like I want to do as much as able on my own? Damned right. And maybe offer assistance to others. My receivable arc is 47.5W to 127W. Possibly 131W if Mr. Stihl and me cooperate here in the land of the ice and snow!

The bigger problem is that in the USA, in addition to the DVB standard, others are also used (almost unavailable here in Europe).
TBS6903 or TBS6903X can be included among the top TBS cards.
In your region, the Ricks Satellite Wildfeed and Backhaul Forum mainly deals with this topic.
As for the impossibility of fullTS with e2 boxes, I read somewhere how to use two utilities (dvbsnoop+dvb???) to create a TS with the required pids.

dvlajkovic · Dec 2, 2022

I second what @EnoSat suggested regarding TBS cards.
If you don't have S2X transponders on satellites that are point of interest, then go for TBS6903.
Only if you have S2X TPs that you want to lock on, then go for TBS6903X.
Both are great cards for any sat-enthusiast.

dvbstream + dvbsnoop for create fullTS in e2 box

Code:

dvbstream `dvbsnoop -s pidscan| awk '/PID found/ { print $3 }' | xargs` -o>full.ts

or
test_dvr + dvbsnoop

Code:

test_dvr new_full.ts 0 1 16 17 20 128 160 256 4109 4111 4113

Thank you for the kind and polite responses guys.
Looking at all of the TBS 5xxx, 6xxx cards is a bit overwhelming.
Searching for user reviews has given mixed opinions.
And dva. That's the thing. A few years ago there weren't many ms tp's that scanned in. Just the last few months loads are scanning in.
If there are S2X tp's or not. The trend might be just like ms. Tomorrow could reveal changes. And several new sats have been put up to replace older ones.
That in itself is raising havoc. Besides the whole 5g thing with lower freq. tp's being shut down, juggling channels from sat to sat.
Yesterday at least 2 tp's on 127W that disappeared a few days earlier came back. The move was to 2 sats over the horizon (or through the trees).
So. A sigh of relief.

So the the 6903 or 6903X it is. Unlike the mio4k or other E2 receivers. Do they lock signal on everything? I've seen the TBS ip/data software module and installed it to look at it.
I need to look at the specs. Before doing it. Does adding the X mean that that card will do more? Do we know what chipsets they use? Are the tuner frontends "hot" (sensetive)?

EnoSat. I have dvbsnoop installed on both ViX and OpenATV. No joy looking for a package for dvbstream. Ideas for an ARM platform?
Mind you not exactly a seasoned Linux guy, surely making an attempt at it.
You do that every bit of educational info. is massively appreciated.
