I think the idea is very good. In fact, this is what I
would like to have, too, only a bit extended/different.
With a modified RTP header you could even have an accurate
PCR sync on the other side of the network... (sorry, just
my dream which probably will never be real due to either
nobody being interested or some company already holding
My idea would be to use an (embedded) processor for doing
all the control and network stuff, and have an FPGA for
the TS handling (and demux). Like this you could have a
DVB card that is not only usable for such a server but
also for a "stand-alone" PC.
Disadvantage: the "multi-frontend" DVB card would have
to have a PCI interface.
Advantage: you could maybe integrate some more fun stuff,
like packet time stamping (MPEG measurement/testing),
accurate (synchronised) PCM/AC-3 output without resampling,
PCR synchronisation on board, section filtering/version
control, etc. Of course this would then be more targeted
for the stand-alone PC, but this is what I am really
missing from all the "solutions" available right now.
Do you have FPGA experience? Are there other people maybe
already working on such a thing? Anybody already implemented
a video decoder in an FPGA, to have a new full-featured
board like this? ;-)
