Hi,

 

There is new test of DVB-S2X tranmission on Hotbird,

 

Eutelsat Hot Bird 13C (13°E) tp. 134 (11,200 GHz, pol. V, SR: 34290, FEC: 32/45; DVB-S2X / 16APSK) ID: Eutelsat Promo TV PID V: 512 (MPEG-4 / SD) PID A: 4112 PID PCR: 512 SID: 1 PID PMT: 256

but there is unable to set up system parameters for DVB-S2X

I can only set up DVB-S and DVB-S2 system. How can I set up DVB-S2X? When using VTi there is possible to choose DVB-S2X but I want to use OpenPLi not VTi   :D

 

Regards,

DJWeed

DVB-S2X is not a seperate system, X means extension of DVB-S2.

Where does this information come from? Both Lyngsat and KingofSat don't have this transponder in their list. If the info is correct, it is probably the FEC that is the problem, never seen 32/45 before, don't think that is supported at the moment.


Currently in use: VU+ Duo 4K (2xFBC S2), VU+ Solo 4K (1xFBC S2), uClan Usytm 4K Ultimate (S2+T2), Octagon SF8008 (S2+T2), Zgemma H9.2H (S2+T2)

Due to my bad health, I will not be very active at times and may be slow to respond. I will not read the forum or PM on a regular basis.

This information came from Polish satkurier.pl 

 

https://satkurier.pl...s2x-na-13e.html

 

When using signal meter You can receive that, see below

 

 

On VTi there is the separate option to set up DVB-S2X parameter and then it is possible to set up more FEC options

Found that page to.

 

We can't see what VTI is doing, they violate the GPL license and don't publish their code.

But maybe there is possible also to add DVB-S2X option to OpenPLi or not?

Everything is possible ;).

 

Al it requires is someone with the correct knowledge and skill, and time to research and implement it,

Recently (Nov 2022) the new fec parameters merged on linux.

https://github.com/t...ce3847aaeeab744

Most probably drivers build with a non standard patch.

What is more disappointing, is auto fec not working. New tuners supposed to detect the fec automatically (as long as they support the new fec).


The correct way to support this, is to backport the patch (on uapi and machine kernel).

Apply then apply new enumerations to e2.

It's a hardware problem that more tuners Short Frame doesn't support
I don't know if anyone can solve this problem because it digs deep into the drivers
In addition, new tuners mostly work in the mode AUTO and it doesn't matter what FEC and MODULATION is entered
 
M88RS6060 no problem
1-0-1-1-1-1-82-ABC0-0-0-0-20230108123957
 
Si2166 It even has problem with Long Frame on DVB-S2X/ACM-VCM (AVL6261 works much better with this signal)

Availink is available on Github.

A ticket created: https://github.com/a...ailink/issues/3



Regarding the VU+, the enumerations used are here: http://code.vuplus.c...e798eb94eb#l303

FEC_Auto=0
FEC_1_2=1
FEC_2_3=2
FEC_3_4=3
FEC_5_6=4
FEC_7_8=5
FEC_8_9=6
FEC_3_5=7
FEC_4_5=8
FEC_9_10=9
FEC_None=15
FEC_13_45=16
FEC_9_20=17
FEC_11_20=18
FEC_23_36=19
FEC_25_36=20
FEC_13_18=21
FEC_26_45=22
FEC_28_45=23
FEC_7_9=24
FEC_77_90=25
FEC_32_45=26
FEC_11_15=27
FEC_1_2_L=28
FEC_8_15_L=29
FEC_3_5_L=30
FEC_2_3_L=31
FEC_5_9_L=32
FEC_26_45_L=33


enum fe_code_rate {
	FEC_NONE = 0,
	FEC_1_2,
	FEC_2_3,
	FEC_3_4,
	FEC_4_5,
	FEC_5_6,
	FEC_6_7,
	FEC_7_8,
	FEC_8_9,
	FEC_AUTO,
	FEC_3_5,
	FEC_9_10,
	FEC_2_5,
	FEC_1_3,
	FEC_1_4,
	FEC_5_9,
	FEC_7_9,
	FEC_8_15,
	FEC_11_15,
	FEC_13_18,
	FEC_9_20,
	FEC_11_20,
	FEC_23_36,
	FEC_25_36,
	FEC_13_45,
	FEC_26_45,
	FEC_28_45,
	FEC_32_45,
	FEC_77_90,
};
They don't match with official fec, (and problem is not the enumeration on e2, but what is send on drivers).

Because in order to support VU+ a new code IF VU THEN VU_FEC Else Linux_FEC will be required.


Anyway S2X, even most promo/demo available are causing problems to receivers. If this technology doesn't become mainstream, don't expect manufactures to really pay attention on this.

Will it not be a problem that we only have AVL6261C verified?

Do you know of any receiver that uses AVL6261A?

I checked also osnino pro, it uses AVL6261C.

 

211268612-bf0dd766-dd8a-439c-a70d-fe473a

 

So no short frames are available on this tuner (16APSK with FEC 32/45 is a short one, https://dvb.org/wp-c..._Feb_2021.pdf).

I also wrote to the Edision company whether it would be possible to use the AVL6261A in my box (use same socket 48 pin QFN) , but no one answered me  :wacko:

too on https://github.com/edision-open

Ι think the AVL6261A is a drop in replacement for AVL6261C.

Hi,

 

Indeed Availink relased a new firmware few hours ago, and they manage to enable short FEC on AVL6261C (although it's not advertised as a supported HW feature).

 

Kudos to Availink!

 

If everything works normally, please let me know if order to create a PR on edision, with the newer firmware.

 

 

Although the initial problem still remains, further investigation required on VU+

 

Does it tune with DVB-S2 and AUTO in FEC ?

Does it tune with DVB-S2X and AUTO in FEC ?

 

(as already mentioned above in DVB API there is no S2X mode)

Hi,

 

Thanks athoik,

 

On my edison os mio 4k+ with openpli 8.3, i have replace dvb-fe-avl62x1.fw

 

With the setting SR 34285 or SR 34290, the video isn't stable, many freez.

 

So, i have a good video with SR 34265, inversion stop, pilot stop & roll-off 0.25 and mode ordinary

It's getting interesting. Until now, the transponder 27W-11609V Siminn Radiomidun provider with IPTV was not available because it works in ShortFrame mode.

Now pids are also available in e2 (and with utilities maybe also userbouquet :P )
