For live streaming video, you mask the loss and keep on chugging just 
like you do with VoIP. The same thing happens with OTA with signal 
fading or a burst of RF noise or interference. The OTA broadcast 
transmitter doesn't retransmit when one or more receivers lose data.

If the endgame is to replace OTA live TV with a packet based solution, 
IMHO there's a place for multicast. It's basically the same model as 
OTA, one transmitter and many receivers.
