Note that each of the Sender units in Figure 2.3 is assigned a unique channel number. However, if we were to change the video channel on Sender unit S1 to channel 1, this would have violated the unicast mode rule: A Sender unit can communicate with only one Receiver unit at a time.
Figure 2.4 - Unicast mode violation: Two Sender units (S1 and S2) using the same video channel.
