Chapter 2-Additional Conferencing Information

A new conference can be started on the DMA using a Conference Profile 

that is defined on the RMX or by defining all the conference parameters. 

The Send Content to Legacy Endpoints option can be enabled only in the 

Conference Profile defined in the RMX, therefore, to include this option in 

the conference started on the DMA use an RMX existing Profile. However, 

the DMA does not display an indication that this option is enabled for the 

conference.

When Contents is sent to legacy endpoints, their video layout 

automatically changes to a “Content layout” which is defined by the 

system flag LEGACY_EP_CONTENT_DEFAULT_LAYOUT and the 

Content is shown in the larger/top left (“speaker”) window. The video 

layouts of the other conference participants do not change.
The switch to the Content layout occurs in the Auto Layout, Presentation 

Mode, Lecture Mode and when a layout is selected for the conference. 

However, in Lecture Mode, when Content is sent to legacy endpoints, 

when switching to the Content layout, the Content is shown in the 

“lecturer/speaker” window and the lecturer is show in a second window. 

If the layout contains more than two windows, all other windows will be 

empty. All other participants will see the lecturer in full screen.
In Same Layout mode, Content cannot be sent to legacy endpoints.
The LEGACY_EP_CONTENT_DEFAULT_LAYOUT Flag default is set to 

a layout of 1+4 where the Content is shown in the large window and the 

other conference participants are shown in the small windows. This 

default value can be changed in the System Configuration. 
When Content is stopped, the layout of the legacy participants returns to 

the last video layout seen prior to the Content mode.
The Legacy participants can change their layout using Click&View. In such 

a case, the Content is forced to the “speaker” window.
The RMX user can also change the layout for the participants the legacy 

endpoints (selecting personal layout).
When forcing a video participant to the Content window (instead of 

Content), the Content display can be restored only by selecting any other 

video layout.
