Unicast and Multicast Modes
Configuring Multicast Mode
The term multicast is used to describe a conî‚¿guration where information is sent from one or
more points to a set of other points. For example, a single Sender unit can transmit data to
multiple Receiver units. In addition, if multiple Sender units are used, each Sender unit can
transmit data to any Receiver that is not already receiving data from another Sender unit.
In multicast mode, the HD over IP w/ RS-232 and 2-way IR functions similar to an HDMI
matrix.
The following illustration shows three Sender units (S1, S2, and S3) and two Receiver units
(R1 and R2) on a network, operating in multicast mode. Sender unit S2 is transmitting the
video signal to Receiver units R1 and R2. The video channels are shown in blue. The
video signals are shown in red.
