 Well... I guess we are both right. :-) They need to assert ownership
 and license the code under the GPL, and we need to ensure that the
 quality of the code is high enough (driver is working and does not
 interfer with other parts of the code base...).

no, they must provide GPLed code accepted by NXP or someone else will do
it. We can't assure quality of code we can't see.

  BTW, the TBS dual seems to be fine on m$, but there are some mysterious
  lockups without any trace, if used in conjunction with some prior
  S2/HDTV cards. I can't tell yet, if that it is evenly distributed over
  amd/ati and nvidia stuff or whatever on win7 ... , but people do spend
  lifetime in vain on it.
 
 This is pretty interesting, do you have any references? (forum links
 or similar)

No, a friend recently bought that card in addition to a Terratec S2 PCI
for his new windows 7 he already had. Likely totally unrelated to linux,
but on his stuff it turned out he can't use both cards at once, single
both are fine.

 In my particular case, I was thinking about using it as the only S2
 card in the machine, later possibly adding a DVB-C card if/when we get
 cable... so, it might not be a problem for me, but it still doesn't
 feel really good. I guess the card is pretty new, so maybe (hopefully)
 it will get fixed by a new firmware release.
 
 Do we have any readers of this list who own the card and use it in
 Linux (with the drivers from TBS)? Could you please share your
 experiences: is the picture quality good? Sound? Does the tuner work
 well? (e.g. can you receive all channels you normally receive...)

Sorry, can't help much yet and can't add anything new.

For now I advised better not to try with binary blobs on linux, he was
already burned enough on win7. He might try later and we will have it
under GPL sooner or later.

Cheers,
Hermann

TBS 6980 Dual DVB-S2 PCIe card

2010-03-04 Thread Per Lundberg
Hi!

I read the old thread about this card, at
http://www.mail-archive.com/linux-media@vger.kernel.org/msg12753.html. I've also
tried downloading the vendor-provided drivers from
http://www.buydvb.net/download2/TBS6980/tbs6980linuxdriver2.6.32.rar

As someone has already indicated, it seems like TBS (TurboSight) have made their
own fork of v4l where the drivers for this card is included. I've also
understood that the card works fine, which is nice (I down own it yet but am
considering getting one).

Has anyone done any attempt at contacting TBS to see if they can release their
changes under the GPLv2? Ideally, they would provide a patch themselves, but it
should be fairly simple to diff the linux/ trees from their provided
linux-s2api-tbs6980.tar.bz2 file with the stock Linux 2.6.32 code... in fact, it
could be that their patch is so trivial that we could just include it in the

We I asked TBS' support about this question they told me they would like

to some of the code in use by some of the chips on the board. No further 
details were provided.

Yes I use the card. Have had it for a couple of months now running in a 
server that acts as a video head-end in my test network. I only tune to 
specific transponders when I boot the server so I can't really comment 
on tuning time and related issues. Yes I've used it for S and S2 feeds 
and so far it fits my requirements.

Re: TBS 6980 Dual DVB-S2 PCIe card

2010-01-20 Thread Dominic Fernandes
Hi,

I just got a new card the TBS 8920 DVB-S2 PCI version.  And having problems 
with MythTV.
I'm running Mythbutu 9.10 with MythTV0.22 and the TBS supplied drivers.  I have 
generated a channels.conf file using scan and can view channels using mplayer 
dvb:// command.

Now I want to import my channels.conf into Mythtv, I gone through the steps of 
specfying the card in Mythtv backend setup, DiSEqC set to LNB, specified path 
and file to import channels.conf file /home/tv/channels.conf.  It then starts 
to do a Scan, but timesout and no channels are found.  I tried increasing the 
timeout values but I get the same result.  

Can you tell me if I'm missing a step?  or how you approached the scanning of 
channels in MythTV

Thanks,
Dominic

I can now confirm it works fine with MythTV 0.22 and at least their version of 
V4L. I tripped up on the known backend defect where you can't obviously select 
the DiSEqC config. See https://bugs.launchpad.net/mythtv/+bug/452894 for more 
info, and the workaround.

I got one last Thursday, also direct from TBS. They provide a mini CD 
with their own V4L which has support for it included, together with 
versions of scan-s2 and szap-s2, but I'm a relative newbie and I've 
already managed to break my MythTV 0.22 setup trying to get it working. 
Any tips on how to get it working with Ubuntu 9.10 and kernel 
2.6.31-16.52 would be very handy.


With their V4L I can only get as far as a successful channel scan.



Ian,

I got my card today and have installed it. Works fine with the drivers 
from the mini CD and the streamer I'm testing against (DVBlast). So 
unfortunately I can't help you with MythTV since I don't use it.


Note that I'm using Ubuntu 9.10 with 2.6.31-16-server

Hello Matthias,

I've ordered a card directly from TBS. It's currently being shipped 
hence I won't be able to test it until at least next week. Then I'll see 
how it behaves in my system alongside all the other cards I have in it.

TBS 6980 Dual DVB-S2 PCIe card

2009-12-02 Thread Thomas Kernen


Hello,

Is someone already working on supporting the TBS 6980 Dual DVB-S2 PCIe 
card? http://www.tbsdtv.com/english/product/6980.html


Chips in use appear to be:
- Conexant CX23885 (PCI Express bridge)
- NXP/Conexant CX24132 (DVB-S/S2 tuner)
- NXP/Conexant CX24117 (DVB-S/S2 demodulator)

I know there is code in v4l-dvb for the CX23885 but I don't think I've 
seen any for the CX24132 and CX24117.


Any insight into supporting this card would be great

Thanks
Thomas
