REQUEST: Time to support DVB-S2X ? #1063
Comments
I think it is perfectly fine to support dvb-s2x. I just do not have the hardware for it. |
Opps, sorry! In my case I've one Edision OS Nino pro (second hand) with a compatible DVB-S2X tuner. I feel it's the cheaper option to have a compatible S2X tuner in a Linux box. Anyway, if you will start some implementation for it, I can check it. Regards. Note: Perhaps the best is to try to start adding support for this tunning mode in the satipc module. I'll try to find one SAT>IP server compatible for initial tests. In any case, for the SAT>IP client side perhaps the code could start parsing the new msys mode and the optional parameters. What you think? |
I can try to work on it, but I think I will need remote access to the box.Otherwise it will be a lot of back and forth with a long development time. |
Seems also needs support in dvb drivers, but isn't: |
Hi @Yuri666 ,
So first we need to found almost one Linux box with valid drivers capable of tuning one of the available DVB-S2X transponders. You have some idea? |
Ok, I have x86 linux box with dvb-s2x card and dish to 13E :) |
Therefore, please could you try to tune 13E 11200V DVB-S2X 16APSK 34290 32/45 with some linux tool and share with us the results? |
I don't see in my dvb card frontend driver code fec=32/45, why needs try to tune? It won't work |
Hi @Yuri666 , Why not try with fec=auto? The info is from here: https://en.kingofsat.net/pos-13E.php However, I feel is wrong as https://www.lyngsat.com/Hotbird-13B-13C-13E.html indicates: 11200 V | DVB-S2 16APSK 34285 3/4. Therefore try with fec=34 and fec=auto. |
Great news! Using current version of the minisatip running in a Edision OS nino pro, this request it's sufficient to tune the 13E DVB-S2X testing transponder: In this request the msys is incorrect, but the driver seems to select the correct one, because the
And here the modulation is correct "APSK/16". From this we can assume that:
Regards. |
Of course i'm tryed fec=auto, fec=3/4, mod=16apsk, mod=auto but without any luck (and any lock). My tbs6504 very sensitive to stream parameters - for example it can't lock dvb-s2 transponder if in parameters set dvb-s. I will try tbs6590 soon. it more tolerant to parameters. But I doubt to success anyway. |
Hi @Yuri666 ,
I don't know, however, now I'm waching the Eutelsat demo channel (just 576p H.264 loop program with 1.5Mbps) from my minisatip central server that uses the Edision STB running another minisatip slave instance. So, at time I feel it isn't necessary to implement new enhancements. Almost until the drivers will be more mature and more transponders will be available. For reference only: If someone wants to test DVB-S2X tunning (with minisatip) try 13E position with this request: Regards. |
mtype=auto mtype=16apsk no lock |
Hi @Yuri666 , Try with "mtype=16apsk" and
These three values are different in my case. |
symbol_rate = 0 is impossible, dvb card can't autodetect symbolrate. |
Therefore I can't help you. 😢 |
Is there anything actionable that can be done to this ticket? Or does DVB-S2X work now? I don't have any such feeds available myself so I'm unable to test. |
As far as I understand, there is no support DVB-S2X in linux drivers now |
dddvb at least for supported cards from Digital Devices should have it |
just FYI Sundtek Dual S2 supports DVB-S2X. I think some here own such a unit? |
Hi @catalinii ,
After reading the issue #978 I feel it's time to add support for DVB-S2X. I've started checking the 19.2E 11008.50V DVB-S2X QPSK 22000 11/20 transponder. My first try is with this URL:
http://192.168.1.133:8080/?freq=11008&src=1&pol=v&msys=dvbs2x&mtype=qpsk&sr=22000&pids=0,1,16,17,18
However it doesn't work. The target is a Edision OS nino pro with a DVB-S2X tuner running the last version of minisatip.
Acording to the documentation:
https://dvb.org/wp-content/uploads/2021/02/A179_Service-discovery-and-delivery-protocols-for-a-DVB-Home-Broadcast-system_Feb-2021.pdf
the URL is valid (check page 37).
At time I don't recommend to support something complex impossible to test it (for example bonding support tunning multiple frequencies at the same time). However, as we have some transponders to test it I suggest to try to add some basic tunning support.
You agree?
Note: Another transponder for testing is: 13E 11200V DVB-S2X 16APSK 34290 32/45.
