Restricting Content Sharing

You can restrict content sharing/broadcasting to the conference lecturer. Restricting content
sharing/broadcasting prevents the accidental interruption or termination of H.239 Content while it is shared
in a conference.
Enable this restriction by setting the RESTRICT_CONTENT_BROADCAST_TO_LECTURER system flag
to ON. For more information about setting this system flag, see
Designating a Participant the Lecturer in an Active
Conference
During an ongoing conference, you can change the conference to Lecture Mode by designating a participant
the lecturer.
In Lecture Mode, all participants see the lecturer in full screen, while the conference lecturer sees all the
other conference participants in the selected layout. When the number of participants in a conference is
greater than the number of cells in the conference layout, switching between participants occurs every 15
seconds. Automatic switching is suspended when one of the participants begins talking, and it is resumed
automatically when the lecturer resumes talking.
To designate a participant the lecturer during the ongoing conference:
1 In the RMX Manager Conferences List, select the active conference of interest.
2 Right click and select Conference Properties.
3 Go to Video Settings, and in the Lecturer field, select the lecturer from the list of the connected
participants.
4 To enable automatic switching between participants viewed on the lecturer's screen, enable Lecturer
View Switching.
5 To change the video layout for the lecturer, select another video layout option.
6 Click OK.

Muting Participants Other Than Lecturer

During an ongoing conference (including a cascaded conference) that is set to Lecture Mode, you can mute
all participants other than the lecturer. This prevents conference participants from interrupting the lecture.
You can enable or disable the Mute Participants Except Lecturer option at any time after the start of the
conference. When enabled, conference participants are not muted until the lecturer joins the conference.
Muted participants can only be unmuted by:
● A RealPresence Collaboration Server administrator or operator or
Polycom, Inc.
