You seem to describe satellite uplink jamming: perturbing the link going from the content provider to the satellite. I would expect this uplink would be redundant and encrypted in some way. Maybe even using optical communication for it, which would enable having a very narrow uplink receiver.
Thinking about it, jamming the downlink in a large area to get the same effect seems to be much harder than jamming the uplink.
