Video Multicast hosting service
 

I need to find a company to host a video feed from my organization, provide a URL to be included on a website that will initiate a muliticast session to the video feed.
HD video feed unicast to hosting company, very large audience 400K plus viewing via multicast from the hosted site.

Any suggestions?

You should contact several web hosts and ask them whether they offer CDN (content delivery network) or not.

You must select video hosting provider were you can easily upload your video

Multicast is an old, but currently emerging, technology that can be used for the more efficient delivery of identical data to one or more clients. Due to these characteristics people are now starting to use multicast across the public Internet to stream audio and video..
