Chapter 3-Video Protocols and Resolution Configuration for CP Conferencing
Polycom, Inc. 3-5
• A different decision matrix is used for Motion and Sharpness as the quality requirements
are different.
By default, the system shipped with three pre-defined settings of the decision matrix for
H.264 Base Profile and three pre-defined settings of the decision matrix for H.264 High Profile
with Motion and Sharpness video quality for each:
•Resource-Quality Balanced (default)
A balance between video quality and resource usage. This is the only available
resolution configuration in version 6.0.x and earlier.
•Resource Optimized
System resource usage is optimized by allowing high resolution connections only at
high line rates and may result in lower video resolutions (in comparison to other
resolution configurations) for some line rates. This option allows to save MCU
resources and increase the number of participant connections.
•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.
Video Resource Usage
Video resource usage is dependent on the participant’s line rate, resolution and Video
Quality settings.
