Take a look at: http://www.vdr-wiki.de/wiki/index.php/HDTV
There are 2 different ways how you could do this:
1. Use a Reel HDe card
Use a Reel HDe card (http://www.vdr-wiki.de/wiki/index.php/Reel-HDe) for video
This will offload you CPU and do the video decoding in hardware.
2. Use softdevice / xineliboutput
Here you will do software decoding. Right now it is extremly CPU intensive. You
need a at least
Dual-Core CPU with 3000+ MHz. I can watch Arte HD with my Athlon X2 6000+ with
a CPU load of ~90%.
You can also use a Nvidia Video card with VDPAU, which will do the decoding in
Then then CPU-Load will be less then 10%, but this is currenly in development
and does not work
reliably right now. Using VDPAU you will be able to watch HDTV with a Atholon
X2 4850e CPU.
There are also Mainboards with onboard Nvidia 9300 or 9400 GPU's. They also
The ATI cards can also do video decoding in hardware, but this is currently not
working with linux at all,
so I would recommend you to get a mainboard with an onboard Nvidia GPU.
To receive Arte HD you need a DVB-S2 card, like the TechnoTrend S2-3200 or the
Hauppauge HVR4000 because
Arte HD is transmitted on DVB-S2 and not DVB-S.
