I believe multicast is only used for IPTV
There is at least one company that is using multicast for video switching, or
in other words to replace HDMI switchers in rooms with video sources and
displays.
They have devices that encode video from an HDMI input to a multicast stream.
And devices that receive a multicast stream and output the video from that
stream to an HDMI output.
So you can have multiple cameras and a multicast stream for each camera is
input into the network.
Then you can have a projector that can choose any of those multicast streams to
display.
I believe the video is uncompressed
Multicast by itself does not reduce much bandwidth : that reduction is
purely based on the network design
If you place unicast nodes near your customers, multicast is effectively
unicast (just think about it) :)

Hi Every one,
Recently we had good discussion over multicast uses in public internet. From
discussion, it was pointed out uses of multicast is more with in enterprise.
Wanted to understand how much % multicast traffic present in network
* If there is any data which can provide what % of traffic is multicast
traffic. And if multicast is removed, how much unicast traffic it would add up?
* Since this forum has people from deployment area, I would love to know if
there is real deployment problems or its pain to deploy multicast.
These questions is to work / discussion in IETF to see what is pain points for
multicast, and how can we simplify it.
Thanks
Mankamana
