Description by fransman:
If the studio is be at a place with only low band width or a bad internet connection and you want to broadcast a satellite uplink. For example with the BBC News (like now with a internet stream) We can do it with a 60-70 dollar linux DVB-S pci satellite card into the scheduler server, but we need a satellite stream element player. The stream is be already real digital MPEG. The main library's are available form Linux TV the DVB (-s satellite) part, supporting a lot of cards. http://www.linuxtv.org/ Are there library's we can use from gstreamer ?

basically add the possibility to schedule playing the input of any sound device into the scheduler
maybe add the same possibility to live mode (basically a mixer into live mode)

I have installed a Techsan Skystar2 pci DVB card.
0001:10:15.0 Network controller: Techsan Electronics Co Ltd B2C2 FlexCopII DVB chip / Technisat SkyStar2 DVB card (rev 02)
It's default supported by the kernel, so load the budget and stv0299 modules by /etc/modules.
[ 60.267215] DVB: registering new adapter (SkyStar2). [ 60.566413] DVB: registering frontend 0 (ST STV0299 DVB-S)...
Directed/set the dish to the Hotbird satellite.
Installed with apt-get the dvbutils and xawtv applications. So it's now possible to checkout the available of free to air channels with scan, creating a channels.conf and switch to one of the channel with szap and view mplayer.
scan -x 0 scan/dvb-s/Hotbird-13.0E > /home/frans/dvb/channels.conf szap -r "RTL9" mplayer dvb://RTL9 -vo x11 -ao alsa
And last but not least found out the availability of the dvbstream library with a pipe-ing methode and got to be able to run a application like xine, but that's fails.
dvbstream -o -ps 600 601 -qam 16 -cr 3_4 | xine stdin://mpeg2

There's dvbstream shell script for radio, using dumprtp with pipeline to mpg123.

I found Gstreamer DVB Source at but this is be tv and i don't have experience with elements http://cvs.freedesktop.org/gstreamer/gst- sandbox/dvb-elements/ =============================================================== GstDvbSrc? makes it possible to view Digital TV with gstreamer. Try: gst-launch dvbsrc freq=11954 pol=h srate=27500 pids=210:220 ! mpegdemux name=demux ! { queue ! mpeg2dec ! xvimagesink } { demux. ! queue ! mad ! osssink } or ./gstdvbtv 2 to view the German 3Sat telestation from the Astra 1 19.2E satellite. The latter command uses the channels.conf in the plugin's directory to fetch the channel parameters. Limitations: DVB-T is not fully implemented. DVB-C is untested, feedback is welcomed.
