Tvheadend

Hi,

Stefan A 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 tvheadend⁵⁶²³: 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 tvheadend⁵⁶²³: diseqc: sending E0 10 5A 5 B8 0
Jul 5 13:40:10 nt425 tvheadend⁵⁶²³: 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,

"uni_pin": -1
}

{

"dmx_path": "/dev/dvb/adapter1/demux0",
"dvr_path": "/dev/dvb/adapter1/dvr0",

}

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

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.

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 configured both 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.

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.

Hello,

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

So that I'll be part of OpenELEC?

@ 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

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.
