This page lists example software configurations that you might find helpful as a suggestion of what you can do with your system.
For a complete list of programs, see the commented software list page --- here, you'll find solutions, not just simple programs. For testing purposed or small systems, have a look at the First steps with a budget DVB card.
In order to be most useful for the reader, this page is diveded into three sections:
- setups for full featured cards (DVB cards with hardware decoders)
- setups for budget cards (DVB cards without hardware decoders) -- see here for USB DVB adapters
- setups for analog TV cards (hey, shouldn't that sort of stuff rather be in the video4linux wiki?
A sample solution for a system with a budget DVB card
My system is a Twinhan DTV Mini Ter on a cheap HP Pentium 4 1.2GHz. The graphic card is only an on-board Intel 82810E with shared memory, so nothing fancy.
After installing the card drivers, I tried several solutions. I didn't get the VDR Software Decoder Plugin working so I tried xine -- which worked on the first trial and provides much functionality (for watching) on an easy and intuitive interface.
A sample solution for a system with a full-featured card
My system is a Mythtv pc installed with Fedora Core 6 following this howto . I use the Technotrend Premium DVB-C 2300 Hybrid dvb-c card bought from Dvb shop in Germany . I was thinking buying the Technotrend Budget C-1500, but it was out of stock from Dvbshop that time .
The Linux 2.6 kernel had already support for Technotrend Premium DVB-C 2300 so the card was autodetected after first time boot. The firmware for the card was not in place so you must download the correct dvb-ttpci-01.fw-2622 (or newer) firmware file from this place . Place this file in the hotplug directory /lib/firmware and rename to dvb-ttpci-01.fw. Change the permission on the file. After a reboot you should get some file in /dev/dvb/adapter0/
Using Fedora, assume root privileges then install the dvb utilities with
# yum install dvb-apps
Scan will need some idea of where to start searching; for this reasons it takes a file for your location as a starting point. Therefore, you need to find channel information for your locality. Again, the location where they are installed may vary. In the following examples, the directory is /usr/share/doc/dvb-utils/examples/scan/dvb-t/; other installations also use /usr/share/doc/dvb-apps-1.1.1 or /usr/local/share/dvb/scan/dvb-t/. DVB-S users should use the folders /usr/share/doc/dvb-utils/examples/scan/dvb-s/, /usr/share/doc/dvb-apps-1.1.1 or /usr/local/share/dvb/scan/dvb-s/. In each case, the name of the file you're looking for is of the form cc-Ttttt, where cc is a two-letter country abbreviation, and Ttttt is the name of the location of the transmitter. So in Adelaide, Australia, you'd look for a file called au-Adelaide; the following example relates to Oxford in the United Kingdom.
I live in Norway and use Grimstad cabeltv. I did not find any channel information file I could use. But I find one for Norwegian UPC which I first take a copy of and then edited it. I got the correct frequency setting, QAM and so on from the cable box Grimstad cabeltv has delivered me.
[mythtv@mythpc ~]$ cat no-oslo-UPC # no-oslo-UPC (cable) C 410000000 6875000 NONE QAM64 C 418000000 6875000 NONE QAM64 C 426000000 6875000 NONE QAM64 C 442000000 6875000 NONE QAM64 C 450000000 6875000 NONE QAM64 C 458000000 6875000 NONE QAM64 C 466000000 6875000 NONE QAM64 C 474000000 6875000 NONE QAM64 C 482000000 6875000 NONE QAM64 C 490000000 6875000 NONE QAM64 C 498000000 6875000 NONE QAM64
After I have edited the file no-oslo-UPC I did a scan.
$ /usr/bin/dvbscan /home/mythtv/no-oslo-UPC
This should produce output saying "WARNING: >>> tuning failed!!!" if a signal was not found on that particular frequency. Eventually, a list of services found should be displayed. Here is a sample list:

This is a list with both radio and tv channels. You have both encrypted and unencrypted channels her also.
Next try to create a "channels.conf", a file in a hidden (dotted) directory off your "home" directory. I make a directory called .czap because I shall use czap to tune in the channels.
$ mkdir ~/.czap $ /usr/bin/dvbscan /home/mythtv/no-oslo-UPC > ~/.czap/channels.conf
Next display the contents of the channels.conf file to make sure the file creation proceeded correctly
$ cat ~/.azap/channels.conf
Note: For reasons not readily apparent, tzap used in the UK example above didn't work. So try azap instead, picking the first entry from ~/.azap/channels.conf (The KPAX-DT part)
$ /usr/bin/azap -r -c ~/.azap/channels.conf "KPAX-DT"
which in turn displays lines similar to (terminate with Ctrl-C)
using '/dev/dvb/adapter0/frontend0' and '/dev/dvb/adapter0/demux0' tuning to 177028615 Hz status 1f | signal 0000 | snr ff28 | ber 00000000 | unc 00000000 | FE_HAS_LOCK ... (repeated output) ...
Then for some statistics, try
(The budget setup above of course also works for FF cards.)
