 |
|
I'm writing this tutorial for dvb-t cards (specifically the AverTV DVB-T), but it should also work fine for dvb-s and -c cards.
Getting your DVB card detected
The first thing we want to do, is make sure our DVB card is detected. Open a Konsole window, and type;
and depending on your card look for lines that start with "bttv:" Here is what it should look like;
| Code: | Real Time Clock Driver v1.12
bttv: driver version 0.9.15 loaded
bttv: using 8 buffers with 2080k (520 pages) each for capture
bttv: Bt8xx card found (0).
ACPI: PCI Interrupt 0000:02:0b.0[A] -> GSI 23 (level, low) -> IRQ 23
bttv0: Bt878 (rev 17) at 0000:02:0b.0, irq: 23, latency: 64, mmio: 0xefefe000
bttv0: detected: AverMedia AverTV DVB-T 761 [card=124], PCI subsystem ID is 1461:0761
bttv0: using: AverMedia AverTV DVB-T 761 [card=124,autodetected]
bttv0: gpio: en=00000000, out=00000000 in=009d008d [init]
bttv0: using tuner=-1
bttv0: registered device video0
bttv0: registered device vbi0
bttv0: PLL: 28636363 => 35468950 .. ok
bttv0: add subdevice "remote0"
bttv0: add subdevice "dvb0"
bt878: AUDIO driver version 0.0.0 loaded
bt878: Bt878 AUDIO function found (0).

If you can't find anything at all, first check the what chipset you have. You can usually find this out on the tuner box, or in hardware detection, in controll pannel, the tv tuner is usually listed as a cammera device. If it says something like ivtv, you need to load the ivtv module;
Then look for lines starting with ivtv: in dmesg
If you still can't find any lines like that, there might still be an additional card-specific module you need to load. do a quite google search to find what the module might be, and load it with modprobe.
If you see some lines, but instead of seeing your model tuner card, you see something like "***UNKOWN or Generic tuner card***" then your card is being detected, but not configured. Things get a bit complicated now, so post below and we can try to work it out.
Setting up DVB
Although our card is detected, we still can't use it to tune a dvb stream, because the modules that route the digital signal are not loaded. we can do do this on this (for bttv chipsets) by;
| Code: | su
modprobe dvb_ttpci
modprobe dvb_bt8xx
|
As I said before, if you have a different chipset, you'll need to load different modules, and you might need to load a card-specific module aswell.
you'll know it worked, when you see similar lines added to the end of dmesg;
| Code: | DVB: registering new adapter (bttv0).
DVB: registering frontend 0 (Spase SP887x DVB-T)... |
The modules will disapear when we reboot, so to get them to stay, we need to open an admin filemanager, and navigate to /etc and open the file "modules" with text editor.
You'll see a long list of singe words, which are a list of modules loaded at start up. I added these lines to the end of the list, but you need to add what ever modules you needed to get your dvb card registered.
| Code: | dvb_ttpci
dvb_bt8xx |
I'm not sure if other cards need to do this, but mine needed the firmware for my card. To see if you need the firmware, try using one of the below, and if you can't get anything, or get errors, have a look at dmesg for for something like
| Code: | waiting for firmware upload... warning!
fimware not uploaded (timout of file not found?)" |
The firmware can be picked up from your wininstallation, and in my case it was called sc_main.mc and was found in /disks/C/Program Files/AVerTV DVB-T. (I think there is an app that you can use to extract the firmware from a windows driver file, without the need to use windows, but I couldn't find it.)
copy it to your home dir, and rename it the file, that the lines in dmesg were looking for (in my case it was dvb-fe-sp887x.fw). Next open an admin file manager, and navigate to /usr/lib/hotplug/firmware, and move the file to here.
Congratulations your dvb card is now ready to use!
Using your DVB card
You can use a number of Applications to view DVB. My favorite, is Kaffene (available from the XORID, or ArchLug repository) because you can scan for channels with a GUI.
You can also use Xine, or a number of other apps, but you have to use scan. You can install in by installing the dvb-utils packag from XN.
You then need to go to /usr/share/doc/dvb-utils/examples/scan/dvb-t/ (there is a directory for dvb-s and -c aswell) and find the file that corresponds to your position. Then goto tools and open console window. In konsole type "scan ./your_region > /home/your_home/channels.conf"
where your_region is the file that corresponds to where you live, and your_home is the name of the current user.
Now that you have a channels.conf, goto your home dir, select View -> show hidden files, and then open .xine, and copy your channels.conf here. You can now open Xine, and press the "dvb" button on the contoles (press g to show the contols), and if you can't see it, it might be hidden. (sometimes when I press the dvb button, I get an error message, but pressing the done button and pressing the dvb button again 1-3 times, will make it work for me).
I believe you can also use Mplayer to watch dvb, but I havent tried this yet.
Getting your remote to work
coming soon. I'm still working on it, but should have a solution by tuesday.

I checked /usr/share/doc/dvb-utils/examples/scan/dvb-t, but I can't find any document that corresponds to California or any where in the US.
What can be done about this?
Thanks in advance,
Randolph

When you get to the point where you really understand your computer, it's probably obsolete. |
