Thomas, I think a lot of DVB-H silicon manufacturers would take exception
to your comment that only Dibcom's solutions provide powersaving via the
timeslicing mechanism - this is one of the fundamentals of DVB-H ;-)
To address Manu's question though, and the answer really depends what is
the goal. The Linux DVB drivers currently don't support specific DVB-H
silicon, so if you're trying to get a specific bit of hardware going, then
you may be out of luck, However, if you simply want to play around with some
DVB-H transport streams, then in many cases you can get away with using DVB-T
hardware and the existing Linux DVB drivers. As long as your DVB-H transmission
is only using options which maintain backwards compatibility with DVB-T (and
most do), then you should be able to use the Linux DVB drivers to get at the
SI and IP (MPE)data.
Chances are that without a lot of work you won't be able to do anything with
the FLUTE/ESG data, but if you can somehow find out the PID and SDP data of the
A/V streams, then you can use dvb-net to route these to the IP stack for
playback via e.g. mplayer etc.
Best wishes.
