DVB-S is a satellite television standard. This article describes the setup and use of DVB-S cards on Arch Linux.

Load required kernel modules
You have to lookup the chipset of your specific card; tools likeAUR may help you.
Pinnacle PCTV Sat
This card uses bt878 and cx24110 as chipset. These require the
cx24110 kernel modules.
Load them with modprobe:
# modprobe dvb-bt8xx # modprobe cx24110
And make them load at boot by creating the following file:
Additional modules: S2-liplianin
Some modules not included in the kernel are available from Igor M. Liplianin's mercurial repository.
First of all, you have to download and prepare the source code.
$ hg clone https://bitbucket.org/liplianin/szap-s2
To clone the repository will need to install or alternatively you can download the source code from https://bitbucket.org/liplianin/szap-s2/downloads/ and extract it manually.
After obtaining the code, change the working directory to the extracted folder:
$ cd s2-liplianin
Unfortunately not all modules of liplianin are compatible with recent kernels and cause some trouble if you want to compile them hence you have to exclude these modules from the build process (if you do not need them). You can choose which modules you want to build by executing:
$ make config
which will create a config file:
After that, you have to build the chosen modules:
If all configured modules were compiled successfully, you can install the modules at the kernel's default modules directory by executing:
# make install
After that, reboot your machine.
Additional firmware: OpenELEC DVB-firmware
The OpenELEC project provides additional firmware files for various DVB devices, eg. TechniSat SkyStar S2. To use these firmware files you can install either AUR or AUR.
To use your DVB-S card as user add him to the
# gpasswd -a [username] video
Most applications like szap or xine are needing a channel list created by scan, which is part of dvb-utils. You will find the dvb-utils package under the nameAUR.
scan needs an channel to initialize scanning. In
/usr/share/dvb/dvb-s/ are some files which contain these channels; you will need that one that fits the satellite you are watching from.
The following command will scan all channels and save them to
$ scan -x0 -t1 -s1 /usr/share/dvb/dvb-s/[your satellite] | tee channels.conf
- The channel file does not have to be called
channels.confbut it is more convenient as you will see later.
- Depending on your satellite dish setup you may have to try other arguments.
AUR allows for automatic scanning of channels without configuration. Install it then issue:
# w_scan -c [your country] > ~/someChannels.conf
Alternatively you can also scan using the satellite position like 19.5E for Astra 1. Scans like that can be done as follows:
# w_scan -fs -s S19E5 > ~/someChannels.conf
You can also add the -X flag to generate tzap/czap/xine output instead of vdr output.
# w_scan -X -c AU > ~/AustraliaChannels.conf
DiSEqC switch scanning (AKA multiple satellite LNB)
If you have a LNB with a DiSEqC switch in it you can manually select that using the -D option like so:
# w_scan -fs -s S23E5 -D 1c > ~/someChannels.conf
The above line should work but not all found channels where actually saved. The line below worked perfectly for me:
# w_scan -fs -s S23E5 -a 0 -D 1c -o 7 -e 2 > ~/someChannels.conf
By using zap, which comes with dvb-utils, you can switch channels, so you do not have to rely on the abilities of your player.
szap needs the channel file we created earlier; it will try
~/.szap/channels.conf by default. You can move the
channels.conf there or you can use the
"-c" command-line option.
Switching channels works like this:
$ szap -r [channel]
You can list all available channels with:
$ szap -q
Now you can watch the stream for example with xine:
$ xine -g stdin://mpeg2 < /dev/dvb/adapter0/dvr0
or with mplayer:
$ mplayer /dev/dvb/adapter0/dvr0
or with mplayer, but using DVB directly:
$ mplayer "dvb://RTL Television"
You can find all the channel names by running
szap -q (assuming the channel list is also in
Kaffeine is a really nice player; it supports EPG, time-shifting, and recording. Additionally Kaffeine has built-in channel-searching.
Install it with the package.
Importing channel list
- Linosaw.de provides channels.conf files for VDR
- conv2conf[dead link 2020-03-28 ⓘ] converts these files into kaffeine channel list format
Me-tv is a simple but powerfull dvb-viewer, supporting EPG, recording and channel-searching with a light-weight gui.
Install Me-tv with the AUR package.
Copy your channel file to
Watch a specific channel with following command:
$ xine dvb://[channel]
or use the playlist editor in Xine
