Chapter 4-Additional Conferencing Information

Polycom, Inc.

Automatic switching between participants viewed on the lecturer’s screen is enabled in the 

conference Profile, or during the ongoing conference, in the Conference Properties. 
>> In the Profile Properties - Video Settings dialog box, select the Lecturer View Switching 

check box. 

This option is activated when the conference includes more sites than windows in the 

selected layout. If this option is disabled, the participants will be displayed in the 

selected video layout without switching.
For more information about Profile definition, see "Defining a CP Conference Profile” on 

>> Once the conference is running, in the Conference Properties - Video Settings dialog box, 

select the Lecturer View Switching check box. 

A conference in which the Lecture Mode is enabled is started as any other conference. The 

conference runs as an audio activated Continuous Presence conference until the lecturer 

connects to the conference. The selected video layout is the one that is activated when the 

conference starts. Once the lecturer is connected, the conference switches to the Lecture 

Mode.
When Lecturer View Switching is activated, it enables automatic switching between the 

conference participants in the lecturer’s video window. The switching in this mode is not 

determined by voice activation and is initiated when the number of participants exceeds the 

number of windows in the selected video layout. In this case, when the switching is 

performed, the system refreshes the display and replaces the last active speaker with the 

current speaker.
When one of the participants is talking, the automatic switching is suspended, showing the 

current speaker, and it is resumed when the lecturer resumes talking.
