In theory (I don't know too much about IP video), you could have a
server PC with a DVB-S PCI tuner, which serves the received IP packets
to the STBs.

A TCP/IP link does need 2-way communication. A one-way satellite link is often
used in conjunction with a modem link for the return path. Or you could set
up a two-way satellite link with the appropriate service provider.

UDP, however, does not. In fact, UDP multicast would seem to be ideal
for this application. Assuming, of course, that all of the routers
along the path through the satellite provider support IP multicast...
