Half our content is satellite feed, the other half comes in on the wan via VPN box. Once it leaves there it goes to another VPN box inside our network (not controlled by us) straight to the NOC where it is decrypted with another box (getting stupid, right?) and then fed into a pair of Verimatrix encryption servers.
Each set top has a key (think of it like a license, and there is a cost per license) that allows it to push the multicast join request upstream.
