What about something even simpler:  an integrated
tuner/demod (Alps BSBE for DVB or Alps TDHU for
QAM/VSB) which both output byte-parallel MPEG-TS, an
FPGA which implements a FIFO, pid filter, and directly
drives a 100mbps ethernet PHY.  This leads to a low
part count, low cost and size. 

The rest of the work can be done by the clients
receiving the stream. 

Regards,
Brian
