Chapter 2-Additional Conferencing Information
2-18
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.
Content Display on Legacy Endpoints
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.
