As you all have said, to confirm, I use ssm Mcast to distribute TV from satellite down links in the headend, out to a few different remote head ends. From there it's converted back to RF video and sent to subscribers via cable or hfc plant
I'm aware that multicast is used extensively for "closed enterprise" networks in the financial and media industries. It seems to work well when a single organization is paying for the entire network. My executive official came from that background, so I get why someone from that world would think multicast is widely used. Asking enterprise network sales people, they keep saying Yes, of course we support multicast. That's why I wanted to hear from public Internet engineers if multicast was still viable on the *public Internet*.
