Chapter 3-Video Protocols and Resolution Configuration for CP Conferencing
Polycom, Inc. 3-13
•Video Quality Optimized
Video is optimized through higher resolution connections at lower line rates increasing
the resource usage at lower line rates. This may decrease the number of participant
connections.
The Video Quality Optimized settings are described in the section: "Default Minimum
Threshold Line Rates and Resource Usage Summary” on page 3-9.
•Manual
Manually adjusting the sliders to accommodate local conferencing requirements.
Resolution Configuration - Detailed
H.264 High Profile allows higher quality video to be transmitted at lower bit rates.
However, setting minimum bit rate thresholds that are lower than the default may affect the
video quality of endpoints that do not support the H.264 High Profile. The Collaboration
Server uses two decision matrices (Base Profile, High Profile) to enable endpoints to connect
according to their capabilities.
Sharpness and Motion
Sharpness and Motion are Video Quality settings that are selected per conference and are
defined in the conference Profile. A conference with Sharpness selected in its Profile uses the
Sharpness settings of the Resolution Configuration and a conference with Motion selected in its
Profile uses the Motion settings of the Resolution Configuration dialog box.
The Sharpness and Motion tabs in the Resolution Configuration dialog box allow you to view
and modify Resolution Configuration settings for conferences with either Video Quality
setting.
Resolution Configuration Sliders
The Detailed Configuration dialog box allows you to configure minimum connection
threshold bit rates for endpoints that support H.264 High Profile and those that do not
support H.264 High Profile by using the following slider panes:
•Base Profile - Endpoints that do not support H.264 High Profile connect at these minimum
threshold bit rates.
Use this option when the priority is to use higher video resolutions while decreasing the number of
participant connections.
