View Full Version : Dual tuner streaming
Multi LNB on a motor. One cable goes to TunerA, second to TunerB
TunerA = positioner
TunerB = second cable...
Can stream any single channel with no issue.
But if I watch a channel on TV, on few channels streaming a different channel (different transponder) is almost impossible (it breaks all the time). While the one on TV is fine or the other way round)
But some combinations of 2 different channels is fine for simultaneous watching & streaming.
So I do not think it is that H7 is not powerful enough to do that
I think I have some settings incorrect.
Is there a way for "force" channel to be received via specific Tuner?
Thanks

It should work fine as long as tuner A doesn't aim the dish away from what Tuner B is receiving.

Should being the operative word. Some do, some do not. It is a single LNB with 2 cables out, so no way to aim it at something different!
What levels are showing on signal on both tuners.
Excellent. 88-90. As I said, it only happens on some combinations of channels

When the dish here was out of alignment and some signals were okay while others were weak or unusable I did find that when one tuner changing transponder could change the S/N ratio on the other enough to change it from weak but usable to not working at all.
But if you have signals that bad something is wrong with the dish alignment, the LNB or the wiring.
Can you tell us some of the combinations that work and don't work?

Then what did you mean by positioner and motor here:
Multi LNB on a motor. One cable goes to TunerA, second to TunerB
TunerA = positioner
TunerB = second cable...

That is not possible in the 'second cable from...' setup.
@Sebus:
1- Are all the channels involved FTA?
2- What happens with the signal quality (SNR, not AGC) when you notice these issues?
Have tested & redone both cables
Each cable separate works fine
But from quad LNB I can only stream a channel & watch another channel from the same TP (like describe here (https://www.boards.ie/mobile/vbulletin/showpost.php?p=115669008&postcount=456))
It makes no difference if channels are enc or FTA

Anybody has any more ideas?
Thanks

Nobody? Is it supposed to work? Depends on the LNB? Used image?

sebusYou need to be specific. Channel you are watching. Channel you are recording.
It is all in first post
There is no recording involved
One channel on TV & another one streamed to PC
Two DO work ONLY if both coming from same transponder
Ok, so you don't want to provide the channel names. Also need settings file from /etc/enigma2.
It does not matter what channels they are, it is the same for each & any pair (same transponder = both fine, different transponders = only first one "wins")
Also it makes no difference in behaviour if they are FTA or encrypted channels

Does picture in picture work?
Anybody any ideas at all?
If you are using pure2 which is what your signature says, then I would suggest you flash openvix and try that…..I have no idea what pure2 are based on as they block access to their code ( they are obviously superior to everybody else), but I assume its openatv which uses different code for tuners.

So it behaves like only one Tuner is working.
Check both tuners are correctly connected and correctly configured.
If you don't have openvix loaded you are posting on the wrong forum.
Your signature shows you have a motorised setup are both channels on the same satellite?
No, I do not have openvix
4 way LNB, 1 direct cable goes to tuner A, second direct cable goes to tuner B
H7S has only a single port per each tuner, so impossible to connect in any other way
Tuner A = USALS
Tuner B = Second cable from motorized LNB
I can watch a channel on TV & stream another to PC ONLY if they both come from same transponder (that also means same satellite)
If they are on different transponders (on SAME satellite) only the first channel wins (whichever one was accessed first, either on TV or via stream)
You are going to have to specify which image you are using because its one area that maybe different between images in the C++. code
Correct info is in signature

That is not a public image, so cannot even view the code to see what is the setup.
SOLVED (none of the above was of any help)
I ended up with changing the LNB (Golden Media 0.1dB PLL gain twin)
At the same time I re-checked both cables, tightened the endings
It all works without issue (FTA or encrypted channels)
So could it be (somehow) LNB?
The image is/was definitely public - zgemmah7-PurE2-7.3-20230818_multi
Just because it no longer shows in https://www.pur-e2.club/OU/images/index.php?dir=7.3/airdigital/ does not make it any different
Yes - all very well, but this is the OpenVix forum.

PueE2 is closed code - so have no idea what these people have done...
