Darwin Streaming Server supports both multicast (broadcast) and

1. Multicast:
Figure 36. Muticast
In a multicast, a single stream is shared among the clients (see

In a unicast, each client initiates its own stream, resulting in the
generation of many one-to-one connections between client and server (see
