What does Multicast mean?
Multicast delivers traffic to a group of interested recipients within a network arrangement that supports it. Some managed television systems use multicast, but the word IPTV does not prove that a particular internet player does. Delivery models need to be verified.

Multicast group handling does not increase the purchased internet line's capacity or grant additional media rights. Keep account and network questions separate.
