4.2 Dominant Speaker Notification

The following diagram represents an exchange of messages between the protocol client and the mixer for dominant speaker notification.

Figure 6: Message exchange for dominant speaker notifications

On the first message, the dominant speaker is notified to be the one with MSI=2. The protocol client can then use this information, perhaps in conjunction with the SDES data communicated through RTCP for MSI=2, to put a visual indicator beside protocol client 2's name on the user interface.

Then the protocol client is talking, and receives a packet from the mixer indicating that it is the current dominant speaker. The protocol client can use the information to put a visual indicator beside its own name on the user interface. The protocol client does not detect this as a loop.
