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).
Lecture Mode Monitoring
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.
If the lecturer is disconnected during an Ongoing Conference, the
conference resumes standard conferencing.
Forcing is enabled at the Conference level only. It applies only to the
video layout viewed by the lecturer as all the other conference
participants see only the lecturer in full screen.
