Video Input Connector [1..5] Optimaldefinition Profile - Cisco TelePresence SX80 Administrator's Manual

Introduction

Video Input Connector [1..5] OptimalDefinition Profile

This setting will only take effect if the corresponding Video Input Connector [n] Quality
setting is set to Motion.
The optimal definition profile reflects the lighting conditions in the video conferencing room
and the quality of the camera. The better lighting conditions and the better quality of the
camera, the higher the profile. In good lighting conditions, the video encoder will provide
better quality (higher resolution or frame rate) for a given call rate. Generally, the Normal or
Medium profiles are recommended. However, when the lighting conditions are very 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. The resolution must be supported by
both the calling and called systems. Use the Video Input Connector [n] OptimalDefinition
Threshold60fps setting to decide when to use the 60 fps frame rate.

Requires user role: ADMIN
Default value: Medium
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.
Video Input Connector [1..5] OptimalDefinition Threshold60fps
For each video input, this setting tells the system the lowest resolution where it should
transmit 60fps. So for all resolutions lower than this, the maximum transmitted frame rate
would be 30fps, while above this resolution 60fps would also be possible, if the available
bandwidth is adequate.

Video Input Connector [1..4] PresentationSelection
Define how the video system will behave when you connect a presentation source to the
video input. In general, any input source can be used as a presentation source; normally,
the main camera will not be used as a presentation source.
If the video system is in standby mode, it will wake up when you connect a presentation
source. Note that sharing the presentation with the far end always requires additional action
(press Share on the user interface).
Requires user role: ADMIN
Default value: Connector 1, 2: Manual Connector 3, 4: OnConnect
Value space: Manual/OnConnect
Manual: In manual mode, the contents of the video input will not be presented on the
screen until you choose it from the user interface.
OnConnect: When in on-connect mode, the content on the video input will be presented
on screen when a cable is connected. Otherwise, the behavior is the same as in manual
mode.
