Tvheadend

Hi, I'm looking for an advise on compiling and installation on my hardware.
I got Dune HD TV-102W sometime ago. This devise having integrated DVBT2 and
Running on linux kernel 2.6.x with it's own drivers and application to watch TV connect to a hdmi port.
The device running on sigma design chips which using mips architecture.
I an disappoint in the lack of support on this media playing part that do not decode some audio codec i.e.. dts.
And the interface for TV viewing is not very nice. Is it possible to do install tv headend on to this device then connect it to my XBMC box by utilized the available drivers in the box.

Best regards,
