In layout 2+8, the two central windows display the last two speakers
in the conference: the current speaker and the "previous" speaker. To
minimize the changes in the layout, when a new speaker is identified
the "previous" speaker is replaced by the new speaker while the cur-
rent speaker remains in his/her window.
The RMX supports the VUI addition to the H.264 protocol for endpoints that
transmit wide video (16:9) in standard 4SIF resolution.
12 To select the Video Layout for the conference, click the required
number of windows from the layouts bar and then select the
