SCR / Unicable

MS Schw · 2013-05-21T22:41:39+00:00

Hello, at the moment I have XBMC running togeather with VDR. But I'm not very satisfied. It takes realy long to switch the channels. I hope that tvheadend...

Ok, I'll test it when I'm home again and try to reproduce it.
I have both a Inverto unicable LNB on one dish and a Inverto IDLP-USS2OO-CUO1O-8PP with two LNBs on another dish to test, so let's hope my setup has the same problem :-)

Stefan Seyfried

I think I found the problem.

Make sure you set the PIN to -1 if you don't need it, otherwise the LNB will not accept the commands.

I'd bet that you have PIN == -1 on SCR2 and PIN == 0 on SCR3.

The problem is, that the web frontend defaults to PIN=0 when adding a new config, which is more often wrong than right.

I'll see what I can do about that, but as I already wrote: the web-stuff is not my strong part :)

Edit: I now pushed an update that defaults to PIN==-1 also for new satellite configs via "Add entry"

Stefan Seyfried

I reworked the code, the setup should now be more logical.

Best is to check out again, since master branch has changed (old master is available as branch "en50494-1st-try").

Now, the SCR#, Frequency and Pin are configured in the adapter configuration, only the port is configured in the satconf settings (port is not often used anyway).

So in your case, configure one adapter to SCR2 and the second to SCR3. I'm pretty sure it will work.

Defaults are also better (PIN is -1 per default).

If this one works well for you, I'll do a pull request to get it upstream.

MS Schw

cool

I'll start with the new code and post the result!

Thanx for your work!!!!!!!

MS Schw

Ok, looks much better now.

Channelscanning works now on both adapters.

Now I can start making the other configuration steps.

Any clue when/if youre code will be added to the main branch? ;)

MS Schw

OK, everything works,
except for the channelimages (imagecache: failed to download /mnt/samba/TV-Aufzeichnungen/xbmc/Channellogos/"zdf hd.png"),
but that is an other topic.

Hi,

@Stefan Seyfried
i tried your version with my unicable setup:
- 3x TechnoTrend AG TT-connect S2-3600

- Inverto UniCable Quad LNB

with all 3 adaoters and just with 1 without a splitter.

syslog with 1 adapter on scr0 1210 Mhz:

Jul 5 13:40:10 nt425 tvheadend[5623]: en50494: fd=12, in=0, v/h=0, l/h=1, f=1951500, pin=-1 qrg=1210 scr=0 ret=1208500
Jul 5 13:40:10 nt425 tvheadend[5623]: diseqc: sending E0 10 5A 5 B8 0

Jul 5 13:40:10 nt425 tvheadend[5623]: dvb: "/dev/dvb/adapter0" tuning via s2api to "12,551,500 kHz Vertical (Default (Port 0, Universal LNB))" (1208500, 22000000 Baud, 5/6, SYS_DVBS, QPSK) for Autoscan

no error is logged.

but tvheadend is not finding any mux.

usb adpaters+tvheadend work on legacy output of the lnb without unicable settings.

hi again,

i replaced 2 technotrends with 2 Opera DVB S1 USB boxes.

and guess what - the older boxes work just fine with unicable.

so i guess its a driver issue with diseqc commands ...

i also tried with the newest v4l-dvb tree.

any advise for me to get the newer TechnoTrend TT-connect S2-3600 to work with unicable?

maybe some older firmware/driver?

Hello,

I'm new to unicable and using latest tvheadend version from unstable repository on Ubuntu 12.04 LTS machine since some month.
Now I have a Inverto Unicable Switch (IDLP-UST111-CU010-8PP) and a Digital Devices Cine S2 V6.5 with extension board after two 3-Way Splitters.

(By the way, connecting the splitter to the standard output of the switch, one receiver works surely fine.)

Unfortunately now I get just some channels found while scanning and none is receivable.

I configured everything as good as I could find in this topic.

Here the configs of my adapter0 and adapter1.

{ "enabled": 1, "fe_path": "/dev/dvb/adapter0/frontend0", "dmx_path": "/dev/dvb/adapter0/demux0", "dvr_path": "/dev/dvb/adapter0/dvr0", "type": "DVB-S", "displayname": "STV090x Multistandard", "autodiscovery": 1, "idlescan": 0, "idleclose": 0, "skip_checksubscr": 0, "sidtochan": 0, "qmon": 0, "poweroff": 0, "nitoid": 0, "diseqc_version": 2, "diseqc_repeats": 0, "extrapriority": 0, "skip_initialscan": 0, "disable_pmt_monitor": 0, "full_mux_rx": -1, "grace_period": 0, "uni_scr": 0, "uni_qrg": 1210, "uni_pin": -1 }

{ "enabled": 1, "fe_path": "/dev/dvb/adapter1/frontend0", "dmx_path": "/dev/dvb/adapter1/demux0", "dvr_path": "/dev/dvb/adapter1/dvr0", "type": "DVB-S", "displayname": "STV090x Multistandard", "autodiscovery": 1, "idlescan": 0, "idleclose": 0, "skip_checksubscr": 0, "sidtochan": 0, "qmon": 0, "poweroff": 0, "nitoid": 0, "diseqc_version": 2, "diseqc_repeats": 0, "extrapriority": 0, "skip_initialscan": 0, "disable_pmt_monitor": 0, "full_mux_rx": -1, "grace_period": 0, "uni_scr": 0, "uni_qrg": 1420, "uni_pin": -1 }

Maybe here is something wrong in my configs or anything I could try.

Stefan Seyfried

Tona: regarding the different devices, one working and the other not: I have really no idea. Maybe you could play with the DiSEqC-Timings in the code to see if that helps. I usually commented on the delays, something like "msleep(25); // EN50494 says 10-60ms", changing the timing might help work around broken drivers / devices. Usually you'll need longer delays, not shorter. If that does not help, you'll need to check the DiSEqC-signal on the antenna cable with an oscilloscope to see what's going on.

Kay: You need to use the version from my github repository, the official tvheadend has no unicable support AFAIK.

Stefan Seyfried

Kay: I saw you are apparently using a unicable-patched version already.

However, obviously your settings are wrong. Check the documentation of your switch. For my inverto switch the SCR / Frequency config is

CH 0 : 1076.06 MHz
CH 1 : 1178.12 MHz
CH 2 : 1280.18 MHz
CH 3 : 1382.24 MHz
CH 4 : 1484.30 MHz
CH 5 : 1586.36 MHz
CH 6 : 1688.42 MHz

CH 7 : 1790.48 MHz

Mine is basically the same as yours, just with 8 inputs instead of 4.

You configuredboth input as SCR0 -- this cannot work. Additionally, you configured frontend0 to 1210 and frontend1 to 1420 -- which is not what the documentation of your switch says.

Kay Jakobs

Stefan: Thank you very much, looks that you're right.

Changed my configs to the following and receiption works

dvbadapters/_dev_dvb_adapter0_STV090x_Multistandard

"uni_scr": 0, "uni_qrg": 1076,

dvbadapters/_dev_dvb_adapter1_STV090x_Multistandard

"uni_scr": 1, "uni_qrg": 1178,

dvbadapters/_dev_dvb_adapter2_STV090x_Multistandard

"uni_scr": 2, "uni_qrg": 1280,

dvbadapters/_dev_dvb_adapter3_STV090x_Multistandard

"uni_scr": 3, "uni_qrg": 1382,

If I understand right, everything is now done in the configs under dvbadapter and there is no special config under dvbsatconf necessary.

MS Schw

Hello,

is there a chance that Unicablesupport will be become part of the "main branch"?

So that I'll be part of OpenELEC?

Sylvio Egal

@ Stefan

I think you are the one posting this?
https://tvheadend.org/issues/1752

I am using openelec 3.2.0 with tvheadend 3.4.27. Could you please explain how to put your unicable patch into tvheadend? I just want to use my new tv-card (DD cineS2), but I dont get unicable to work :(

thanks, sylvio

Stefan Seyfried

I rebased the code against current git master and sent a pull request: https://github.com/tvheadend/tvheadend/pull/298

Today I installed seife's fork of TVHeadend from his GIT. After deactivating libav before make I was able to compile. With libav I had a bunch of compile errors. I need the SCR Feature. Unfortunately after launching and configuring I only see 0% Reception and no channels/muxes are being found. Since I do not know what information you guys need to help me I will start with a screenshot of my dvb-adapter config. Please tell me what else you need. I use an Inverto Unicable LNB and the frequencies are according to the manual.

/edit: installed 3.9.1608~gab8af7c from git today and scr works with my TT S2-1600 DVB-S2 card.
