Contents Introduction
xConfiguration Video Input Source [1..2] PresentationSelection
In general, any input source can be used as a presentation source; normally, the main camera (self view)
will not be used as a presentation source.
This setting is used to define whether to display the presentation source on the local video system's
display automatically or not. To share the presentation with the far end always requires additional action
(tap Start Presenting on the Touch controller or the Presentation key on the remote control).
The default values for all input sources are Manual.
Requires user role: ADMIN
Value space: <Manual/Automatic/Hidden>
Manual: The content on the input source will not be presented on the local video system's display
before you select it. Use either the remote control or the Touch controller to choose which input
source to present.
Automatic: Any content on the input source will be presented on the local video system's display
automatically. If there is active content on more than one input source (which is set to Automatic)
the most recent one will be used.
Hidden: The input source is not expected to be used as a presentation source.
example: xConfiguration Video Input Source 1 PresentationSelection: Manual
xConfiguration Video Input Source [1..2] CameraControl Mode
Select whether or not to enable camera control for the selected video input source when the video
input is active.
Requires user role: ADMIN

xConfiguration Video Input Source [1..2] OptimalDefinition Profile
58
xCommand
The Video Input Source Quality setting must be set to Motion for the optimal definition settings to take
any effect.
The optimal definition profile should reflect the lighting conditions in your room and the quality of the
video input (camera); the better the lighting conditions and video input, the higher the profile. Then, in
good lighting conditions, the video encoder will provide better quality (higher resolution or frame rate)
for a given call rate.
Generally, we recommend using the Normal or Medium profiles. However, when the lighting conditions
are good, the High profile can be set in order to increase the resolution for a given call rate.
Some typical resolutions used for different optimal definition profiles, call rates and transmit frame rates
are shown in the table below. It is assumed that dual video is not used. The resolution must be supported
by both the calling and called systems.
Use the Video Input Source OptimalDefinition Threshold60fps setting to decide when to use the 60
fps frame rate.

.
Requires user role: ADMIN
Value space: <Normal/Medium/High>
Normal: Use this profile for a normally to poorly lit environment. Resolutions will be set rather
conservative.
Medium: Requires good and stable lighting conditions and a good quality video input. For some call
rates this leads to higher resolution.
High: Requires nearly optimal video conferencing lighting conditions and a good quality video input
in order to achieve a good overall experience. Rather high resolutions will be used.
example: xConfiguration Video Input Source 1 OptimalDefinition Profile: Normal
