This page provides examples of working hardware and software system configurations that may provide guidance for readers as to what can be accomplished on or with their own system.

If you believe you have a PVR / Linuxtv box that works well, please post a description that may be beneficial for others to read [such as your system hardware (mobo/chip/video), what TV tuner device you have (ideally with a link to the manufacturer's product page or to the device's entry here in the wiki) and with what kernel, drivers and software applications you operate on your system].

In order to be most useful for the reader, this page is divided into three sections:

  • setups for DVB cards that rely on "software decoding" (aka budget cards ... DVB cards without hardware decoders)
  • setups for DVB cards with hardware decoders (aka full featured cards)
  • setups for analog TV cards (hey, shouldn't that sort of stuff rather be in the video4linux wiki?

Each of the three sections can, in turn, be subdivided into categories covering the different standards (DVB-{C,S,T}, ATSC) for that type of hardware. Please add to the appropriate one, or create a new one if need be.

Readers should note that the suggestions found here are just that -- suggestions. For a more complete listing of available software programs, see the commented software list page. Likewise, for more complete listings of supported hardware, consult the [Hardware & Components] section of the 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.

I use a Twinhan Express compatible card Axtrom which works great with linux. So far kaffeine is the best choice to use with a budget card. Since xine does not let you to record and it's interface is buggy and VDR is very hard to setup and startup I decided to stick to kaffeine. It lets you record un-attended. you can even record and watch multiple channels within same transponder.

DVB-T example
Nova-T stick

Via SP13000 epia system Fedora Core 6

kernel: 2.6.18-1.2869.fc6

Drivers extracted from hg

Works reasonably well, records about 8 TV programs a day using freevo. Get kernel ops requiring reboot about once a month, can be slow to tune and sometimes doesn't tune at all.


A sample solution for a system with a full-featured card

DVB-C example
My system is a Mythtv pc installed with Fedora Core 6 following this howto [1]. I use the TechnoTrend Premium C-2300 hybrid DVB-C card [2]bought from Dvbshop in Germany . I was thinking buying the Technotrend Budget C-1500, but it was out of stock from Dvbshop that time [3]. I am going to document in the Mythtv Wiki howto use the channels.conf file for setting up channels in Mythtv.

---The following info showed be moved to a more appropriate place in the wiki ---

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:

dumping lists (7 services)

TV3 Norge:410000000:INVERSION_AUTO:6875000:FEC_NONE:QAM_64:1111:1112:1110

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. Czap is only for cable broadcasting, then you have tzap for terrestial and then szap for satelite.

 $ 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 ~/.czap/channels.conf

Then you can try to tune in one of the channels:

 $ /usr/bin/czap  -r -c ~/.czap/channels.conf "ZTV Norway"

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) ...
