Sat>IP

Hi
is there a way to get SageTV to use a sat>IP server as a network tuner either directly or via OpenDCT?

If it helps here is the sat>ip protocol:

Thanks
Eric

What server devices are supported?

In my specific case I am using a megasat sat>ip server 3 (they thought long and hard about that name).

https://www.megasat.tv/en/produkt/sat-ip-server-3/

This provides eight tuners from 4x satellite connections from either a quad or a quattro LNB.

One complication is that the megasat is not setup with the frequencies for the astra 28.2 satellite (which is what the dish is pointed at). However it is recognised as eight tuners by NextPVR which is able to scan for a full bouquet of channels successfully.

Similarly TVHeadend will discover the tuners and scan for channels successfully. I think Sage user @rickgillyon uses TVHeadend as a bridge to re-serve sat>ip streams that OpenDCT can request using its command line syntax (or perhaps TVHeadend will emulate an HDHomerun? This is the route that I'm trying to follow ATM, but I'm a novice with TVHeadend and my Sage install is on Windows not linux, so far its a slow process).

My understanding is that the sat>ip protocol is common to all sat>ip servers and that it will take frequency, polarisation etc switches from either an RTSP or an HTTP request (the protocol booklet I linked has details and examples and I've manually used them successfully in VLC player). Unfortunately my ability to use this knowledge is zero.

OpenDCT alone cannot see the sat>ip server on my network.

Thanks for any guidance.

Cheers

Eric

WOW

This is incredibly intriguing!!

I've been thinking recently to a simple way of improving my setup by having a 4W max power consumption pico/nano ITX or NUC system to run a STV server only, but having 2 Quad DVB/S2 tuners to use things become complicated as such systems have limited/not standard PCIe bus or miniPCIe connectors that can export a couple of standard PCIe bus via a riser card, but it all seems to me incredibly flaky.

Another solution could be the HD-HomeRun network encoders already supported by STV but unfortunately not available for DVB-S standard, as yet?

I know you can make a network encoder by having one STV server running where the tuners are and connecting to another STV server, but again this is not a cheap low power solution and it requires two separate builds anyway.

Then I stumbled into this Sat>IP thing, eagerly read the specification and though this is exactly what I want for my future setup. but it is not directly supported by STV.

Reading around I found some people have tried chaining different piece of software together to have STV ingesting the SAT>IP protocol with more or less success, but I'm always for simple, rock solid solutions and with that precise spirit I've developed the DVB Decrypter, simple, direct, native.

It is still very early days, but I can somehow see developing a generic BDA driver for SAT>IP server as the most viable, cleanest and direct path to have this technology integrated to STV as a native tuner....and all the rest should just fit it as normal, will see

Stay tuned!
Eddy

It would be awesome if this could be done as I have not had chance to patch together a solution. Google

I note that the 8 tuner megasat server that I linked above appears no longer to be made. Google tells me there are still some in retail channels (at discounted prices).

Mine has been powered up for months and hasn't failed (or even get hot) but I've not been able to stress test it. npvr appears to lose connection to it (TVHeadend didn't).

I'm sure you are aware but google implies that there is a solution under linux (I haven't had chance to try; maybe over christmas so I don't know if it works).

The big DVB thread may also be of interest

But again I'm sure that you've seen.

Hi, thanks for the info, I was aware of a different virtual tuner solution but more interested on the Windows development. I bought few books about Windows Driver Foundation development I'm currently reading (massive books BTW) trying to gather more information. From the surface I discovered that Windows 10 makes somehow harder to develop kernel drivers in terms of validation because every driver must be submitted to Microsoft for scrutiny and initial acceptance.

Initial development should start at some point next year with the aim of completion by end of 2020.

Cheers
Eddy
