There is a jump of logic.

First, we should have STBes to generate not decoded video
signal over HDMI but encoded video over IP over Ethernet.

Though IP packets may be carried to anywhere, which makes
regional restrictions meaningless, (re-encoded) decoded
video can be carried by IP anyway.

We should also use IP even over radio waves. IP over MPEG2-TS
over DVB (or terrestrial broadcast network) is doable though
IP directly over DVB should be better.

Unicast video over satellite link costs a lot.
