X1 Layout Scenario Adaptation - Polycom realpresence 1800 Administrator's Manual

● Remote participants (that is, connected to a cascaded conference) are not included in the count, as
well as the cascading link itself. Layout indications are displayed within each Collaboration Server
participants independently, thus no layout indications are embedded in the video sent towards the
cascading link.
In that context, Lync endpoints connected via the AV MCU are included in the count, although other
video participants connected to the AV MCU conference are not included.
● The Layout Indications tab is hidden in SVC, VSW, and TIP-enabled conferences.
● Layout indications can be set only in conference profiles, and not for ongoing conferences.
● The same indication display duration is applicable for all indications.
● For TelePresence endpoints:
 The layout indications appear only on the main screen.
 Only non-TIP endpoints can view the layout indications.
 TelePresence rooms with three screens are considered as a single endpoint in the video
endpoints count.
● Upgrade of endpoints from audio to video, or downgrade from video to audio, is reflected in the layout
indications count.
● PSTN/H.323 audio participants calling the Collaboration Server Gateway profile, and dialing-out a
VMR on the DMA via SIP/H.323, are counted as either an audio or a video endpoint, regardless of
the Collaboration Server they are connected to.
● AVC endpoints connected to a Polycom® RealPresence® WebSuite™ client, can view layout
indications, depending on the conference profile configuration.

1x1 Layout Scenario Adaptation

To display indications according to the local endpoint's capability (4CIF and up), Collaboration Servers
(2000/4000) should disable the system's 1x1 layout functionality that includes sending the current speaker's
resolution.
For example, in a conference between two video endpoints the layout is 1x1 by default. If the resolution of
one of the endpoints is lower than 4CIF and the other higher than 4CIF, RealPresence Collaboration Servers
2000/4000 will follow the speaker and not transmit the Indication Icons when the lower resolution endpoint
is the active speaker. (RealPresence Collaboration Servers 1800 never follow the speaker.) As a result, the
endpoint capable of higher resolution will not receive the Indication Icons.
For further details on how to determine the layout indications position, see
Indications Parameters.
This behavior can be modified by manually adding the
HW_FOLLOW_SPEAKER_RESOLUTION_ON_1X1_LAYOUT flag to the System Configuration and
modifying its value.
For more information, see HW_FOLLOW_SPEAKER_RESOLUTION_ON_1X1_LAYOUT.
Lecture Mode
Lecture Mode enables all participants to view the lecturer in full screen while the conference lecturer sees
all the other conference participants in the selected layout while he/she is speaking. When the number of
sites/endpoints exceeds the number of video windows in the layout, switching between participants occurs
