Use of Broadcasting and Multicasting in IPTV

I need some text about use of Broadcasting in IPTV, I have lots of text about Multicasting in IPTV in some PDF’s, but nothing about Broadcasting.

Networking has 3 basic modes, unicast (1 to 1), multicast (1 to many, those many has registered a group for this specific multicast) and broadcast (1 to all, all does not include the sender). Unlike traditional Air/Cable/Sat TV in which a content is broadcast through a fixed channel, IPTV are generally implemented with multicast since broadcast from a network node would flood those neighboring nodes who do not want that specific information. If all nodes from a specific node A has registered a multicast group and A is the source, then even data flow looks like a broadcast case, but it is still a multicast.
