Hi to all Linux Users.
http://e1h7.simplecdn.net/lqcdn/imag...s_lq/icon7.gif
In 2010 in Mauritius, there will be no analog tv channels only digital ones.
http://e1h7.simplecdn.net/lqcdn/imag...s_lq/icon9.gif
Can anyone recommend me which DVB card is fully supported in linux.

The website linux-tv did not show any good information. http://e1h7.simplecdn.net/lqcdn/imag..._lq/icon13.gif

Also there is this thread
http://e1h7.simplecdn.net/lqcdn/imag...s_lq/icon7.gif
http://www.linuxquestions.org/questi...evices-770320/

I'm searching for a pci device instead of a USB onehttp://e1h7.simplecdn.net/lqcdn/imag..._lq/icon12.gif
http://e1h7.simplecdn.net/lqcdn/imag..._lq/icon10.gif (I f*cked my USB ports but they work and pci should put less strain on the system I think )http://e1h7.simplecdn.net/lqcdn/imag..._lq/icon10.gif

The smilies are nice but...

It might be of help if you mentioned what standard of digital signal the card is expected to receive. Is it DVB-T2?

I dont know what standard of digital signal is to be recieved, but the video codec is mpeg2 if that can help.

You can get "smilies" without putting in all those links---just go to advanced editing mode.

Those links make your post really cluttered and hard to read.

As for your question, someone in your local area will surely know the standard to be used---I would start by calling the local TV stations.

From the link http://www.dvb.org/about_dvb/dvb_wor...tius/index.xml

it seems to be dvb-t . Are there other formats ?

Google found this:

http://www.dvb.org/technology/index.xml

After spending some time searching here and there, only one product was available in the market and thanks tux that it works on linux (I haven't yet tested it on FreeBSD, NetBSD, OpenBSD ).

It is a hybrid TV pci card with the ability to play DVB-T, analog SECAM-B TV and FM radio.

My current Slackware 13.0 detected it as follows :

Is there anything I missed?


PS: Also, I'm testing on Mandriva 2010's tv-time, it seems to be able to scan for analog tv channels and find them but because of no existing X-Video extension it refuses to display anything (I'm currently working on a better xorg.conf file for the moment)

Just a thought...

Despite the fact that they may not be directly relevant, have you tried to look on the IVTV or MythTV forums for any useful hints or information?

By the way, you don't need large, bold type; any useful reply will not come sooner by raising your typographical voice.

I have correctly setup modprobe.d for the saa7134 module to receive the analog tv signals. The tuner has been detected (both tda829x and tda18271 are loaded) , and I'm getting the video signal but the audio is missing with only a hissing sound being heard, tried sox piping from /dev/dsp1 to /dev/dsp .
I have captured the sound into a pcm file and there was only noise in it.

I have recompiled the 2.6.32.3 kernel with full debugging options and added more debug options in modprobe.d files:

The problem stems from : "[ 11.463287] saa7133[0]/audio: sound IF not in use, skipping scan
"

The audio signal is not being demodulated.

How can I know what is not working?


PS: With a wrong option in '/etc/modprobe.d/saa7134.conf' both tuners (tda829x and tda18271) were not loaded instead it was the module 'TDA 9885/6/7 analog IF demodulator' which got loaded at the same memory address. Is this normal ?

After some heavy testing and looking around the net , I have come to conclusion that my tv card is partially detected by the linux kernel.

The pci interface chip saa7134 works in linux, and the analog tuner 'tda18270 + tda8970' is tuning to the proper channels.
I grepped and snooped into the source codes to find that to write a patch is going to be a hell of a job since I will be needing a stable internet connection .

Can some one direct me to whom I shall have to contact to get my tv card work on linux.
It will be great having someone helping me on the I2C programming part of the saa7134 since I am not being able to make this chip detect the tda10048 digital tuner .

Finally it works(I think so),

I have the slackware 13.1 kernel 2.6.33.4 , the TVcard Gigabyte_GT-P8000 is detected by an insmod option :
modprobe saa7134 card=173

but the full functionality is not available, the analog tv and the dvb-t part was detected and it properly uploaded this firmware(attached to this post, just remove the .txt part from the file).

But the scan program(from dvb-utils is not finding any channel)


Hi can anyone update this info on the webpage ::: http://linuxtv.org/wiki/index.php/Gigabyte_GT-P8000.

This is a crash I got from dmesg when doing a dvb scan of saa7134, is this related and to whom do I have to submit this crash.

Finally it works,

I have the slackware 13.1 kernel 2.6.33.4 , the TVcard Gigabyte_GT-P8000 is detected by an insmod option :
modprobe saa7134 card=175 tuner=54

but the full functionality is not available in this card options. The tuner is NXP 8750/18750 working on all card options.

When the saa7134 module is loaded as card=175 only dvb-t option is working. The scan program finds two frequency at 482000000Hz and 530000000Hz with a bandwidth of 8Mhz and all other options being at auto. MPlayer and mencoder works properly on the MPEG streams but a combination of cache=80Mb and -vo X11 sometimes produces an unexpected MPlayer crash. XINE takes a very long time to change from channel to another.

Other card options make the S-video & video capture (card=1, 17, 173), radio (card=1) , analog tv (card=1,17) work but audio is still not working.


Hi can anyone update this info on the webpage ::: http://linuxtv.org/wiki/index.php/Gigabyte_GT-P8000 and close this thread.

PS: Now that I have dvb-t working , I won't be testing my GT-P8000 card for sometime , I'm testing another tvcard for the moment , an old Zoltrix Genie card that won't even work on neither winxp nor win7.

I tried to debug the seperate ir module in 2.6.38 but to no avail.

The module does not send any keystroke response
