We have a IP STB for terrestrial use and want to add a satellite receiver to
it.

We want to send IP over a satellite link, down to a STB that has a Windows
Media decoder in it.... firstly can you do this over a one way system, that
is to say you download information basically off an IP network but you have
no path for the system to communicate back over, I would say no as TCP/IP
needs to know the packets got there, and in this system we would be only one
direction.

Also is there another way to get data to the set top box? other the the DVB
route? We have a lot at our disposal here but do not know what to use.

Thanks!

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...
