stream according to the larger dimension of the pane.
For example, in the layout to the left, the size of the top left pane is one half of the view width and two thirds
of the view height. Because two thirds is greater than one half, the MCU scales the participant video stream
to two thirds of its size and thus a small amount of the left and right of the original image will not appear in the
final composed layout.

Video stream vs. fixed bitmap images
For video conference participants, the image that displays in the layout view pane is either the live video
stream (if viewing from the video endpoint) or a captured video image from the current video stream (if
viewing from the web interface).
stream (if viewing from the video endpoint) or a captured video image from the current video stream (if

However, audio-only participants do not have any associated video to display. Instead, you can assign a
fixed image (in bitmap format) to a specific participant. When the participant joins a conference as an audio-
only participant, this image appears in the layout pane. To enable this feature, the participant must be added
as a user to the MCU, have an associated E.164 telephone, and have a designated image file uploaded. See

Muted participants
Audio mute
Participants who have had their audio muted from the web interface do not contribute audio to the
conference. Additionally, muted participants are not considered when the MCU calculates the loudest
speakers to display in the largest panes, even if the participant had previously been in one of those positions.

Note that other participants will not have an indication that a participant has been muted. They simply will no

Automatic lecture mode
Automatic lecture mode allows a lecturer to be shown in full-screen view to the students. In this mode, the
lecturer will continue to see the normal (continuous presence) view. That is, the lecturer will see the students
and not himself. When Automatic lecture mode is enabled for a conference, the MCU identifies the
loudest speaker as the lecturer. If you have configured a custom layout for the lecturer, that will override the
normal continuous presence view. For the other participants (the students), the view of the lecturer (the
loudest speaker) overrides any custom layout. You can enable automatic lecture mode for scheduled and/or
ad hoc conferences either in the conference configuration or in the relevant conference template.
