Dear all,
I decided to post a patch against the TBS drivers for all those who
want to experiment
with the very preliminary base-band demultiplexer until I have a
repository to properly host
this stuff. Currently it only works for the
TBS 6925 card. The bb-dmx was created for Linux v3.3, so the patch
also contains some
changes that made it into Linux since TBS driver release v111118. You
can get the TBS source
code via this direct link (I know there's a newer version but the
patch is against the old driver package):
http://www.tbsdtv.com/download/document/common/tbs-linux-drivers_v111118.zip
And then you can download the bb-dmx patch from here:
http://www.cosy.sbg.ac.at/~cpraehaus/download/tbs_v111118_bb-dmx_2012-03-19.patch.gz
Tuning and configuration of the card is as normal, notice however that
the card is currently
put in base-band data mode irrespective of any configuration. This
means that you probably wont
be able to receive DVB-S.
To test the bb-dmx support, there is a patch against dvbsnoop 1.4.5.
You can get the source from the SF site:
http://dvbsnoop.sourceforge.net/
and the patch from here:
http://www.cosy.sbg.ac.at/~cpraehaus/download/dvbsnoop-1.4.50_bb-dmx_2012-03-19.patch
Usage:
dvbsnoop -s bb <ISI> (receive bbframes from <ISI>)
dvbsnoop -s bb -tsraw (receive everything)
Sorry, its still all very experimental and DVB-S2 specific, but I'd be
happy to get feedback from those interested.
Thanks and kind regards,
Christian.

Dear all,
First, thanks for your interest in this functionality. I think the
modifications
are in a shape where they begin to be useful for others. Currently
I'm (still) trying to get some GIT repo where I can host the whole
stuff.
Thank you all for your support, testing will indeed by important
after the first
version is "in the wild" :-). I definitely want to keep this going
and be sure
that I tell you as soon as the code can be accessed.
Kind regards,
Christian.

Hi Konstantin,
all work to support BBFrames in the Linux kernel is done by
Christian
- in fact it's a long lost work from 5 years ago:
http://www.linuxtv.org/pipermail/linux-dvb/2007-December/022217.html
yep, I have followed the history back... and like Christian said,
the
old repo is nolonger working. :(
and i hope it won't be lost again. i just encouraged Christian that
his work is important and there are people interested in it - you're
one such example. so, i offered Christian to help him with i can. i
guess more people appreciating what his doing and encourage him will
give him better motivation to release the code to the public.
however,
i guess the delay is more, because it's not easy and it requires
time
to prepare the code for initial public release and that's why the
delay. so, i don't have Christian's code and i'm eager as you're
to be
able to try it out, but we need to be patient. i'm sure that after
there is some public release and repository more people will be
interested to contribute to that work.
best regards,
konstantin
Agreed, I understand the pressure of releasing publicly. Once
released,
the nit picking begins.. lol. I will keep watch on the list.
Christian, if you want an extra tester to help yah, count me in.
I'll
help also with what I can.
Bob
