Discussion Mode is triggered once the number of participants reaches a minimum, and one of the
participants becomes the active speaker by speaking over a time interval (see
Layout Usage Criteria
● A 1+7 layout is used for single speaker scenarios.
● While a 1+7 layout is used, should another participant become an active speaker, the 1+7 layout is
replaced by a 2+8 layout.
● While a 2+8 layout is used, once another participant becomes the active speaker, its video, if exists
(i.e. not an audio participant and video is not muted), replaces that of the active speaker preceding
the last speaker. If no video is sent for the speaker, both the layout and speakers remain as is.
● While a 2+8 layout is used, and only one participant remains the active speaker, the 2+8 layout is
replaced by a 1+7 layout, with the two least active participants moved out of the layout.
● The active speakers do not view their own video, but that of the last active speaker(s).
● At all times, the most recent active speaker is displayed in the top-left cell. The smaller cells are
populated bottom up, right to left.
● More than 10 participants do not result in using layouts with larger number of cells.
