•

Enable or disable the Lecturer View Switching between participants displayed on the 

lecturer monitor by selecting or clearing the Lecturer View Switching check box.

•

Change the video layout for the lecturer by selecting another video layout.

Content broadcasting can be restricted to the conference lecturer only, when one of the 

conference participants is set as the lecturer (and not automatically selected by the system). 

Restricting the Content Broadcast prevents the accidental interruption or termination of 

H.239 Content that is being shared in a conference.
Content Broadcast restriction is enabled by setting the 

RESTRICT_CONTENT_BROADCAST_TO_LECTURER system flag to ON. When set to 

OFF (default) it enables all users to send Content.
When enabled, the following rules apply:
•

Content can only be sent by the designated lecturer. When any other participant tries to 

send Content, the request is rejected.

•

If the RMX user changes the designated lecturer (in the Conference Properties - Video 

Settings dialog box), the Content of the current lecturer is stopped immediately and 

cannot be renewed. 

•

The RMX User can abort the H.239 Session of the lecturer.

•

Content Broadcasting is not implemented in conferences that do not include a 

designated lecturer and the lecturer is automatically selected by the system (for 

example, in Presentation Mode).
