Cisco Cisco TelePresence MCU 4510 Maintenance Manual
Participants viewing themselves
When considering which participants to show in which panes, a participant's self view has the lowest priority.
This has two main implications:
This has two main implications:

Participant pane selection
When choosing participants to display, the MCU considers the viewer last. This prevents the participant
who is the active speaker from seeing only themselves. In this case, while everyone else will see the
active speaker, the active speaker will see the previous active speaker in their biggest view pane.

View family layout selection
When the MCU is required to choose a layout from a view family, it does so based on the number of video
contributors to the conference. However, when calculating the number of video contributors for a particular
view, the MCU does not consider any video stream being received from the viewer.
Thus, with five participants in a conference and everyone seeing the standard equal-sized view family
(2x2, 3x3 or 4x4), each of the five contributing participants will always see the 2x2 view with themselves
excluded. However, streaming viewers will see the conference display using the 3x3 view with five panes
in use.

You may configure the MCU never to show participants their own video stream in small panes (see
). If this is the case, then participants viewing layouts with some
panes larger than others will never see their own video stream in any of the small panes, even if there are free
slots. They may still appear in large panes, for example if the view focus is manually changed to show their
video.

Changing view focus
Using the tilt (up and down) far-end camera controls on a connected video endpoint causes the view to
change, cycling through the available families and then the conference-wide or per-participant custom
layouts (if enabled).

layouts (if enabled).
In addition, the pan (left and right) far-end camera controls on a connected video endpoint can be used to
focus the view on a particular participant, as opposed to the MCU allocating participants to panes based
solely on the volume of the audio being received from them.

solely on the volume of the audio being received from them.
To reduce the disruption of the view when cycling through conference participants, there is a short delay after
selecting a new focused participant before the rest of the view layout reverts to the "correct" arrangement of
participants in panes.

"Important" participants
For each conference, one active participant can be set as "important". This means that the MCU considers
this participant first when deciding which contributors to show in which layout panes, rather than their
position in the list being set by how loudly they are speaking. See the

"Important" participants combined with view focus
Both "Changing view focus" and "Important participants" above involve a single specific participant being
shown in the biggest pane available, even if that participant is not currently the loudest speaker. This causes
a potential conflict, which is resolved dependant on the type of layout.
