The choice between multicast and unicast depends on a number of network
factors. 

Unicast is typically required when security is a bit more of a concern; while
multicast puts lower requirements on the sender and the first part of the
network when a lot of clients share the same source.

e.g. when 20 clients connect to channel one of a 16 channel encoder; in the
case of unicast you're sending out 20x4 mbps; while in the case of multicast
you can do with 4 mbps and the last part of the network will do the stream
multiplication on switch level.
