Video Protocols and Resolution Configuration for CP Conferencing
Polycom®, Inc. 96

Flag Settings

Setting the Maximum CP Resolution for Conferencing
The MAX_CP_RESOLUTION flag value is applied to the system during First-time Power-up and after a
system upgrade. The default value is HD720p30.
All subsequent changes to the Maximum CP Resolution of the system are made by selections in the Max
Resolution pane of the Resolution Configuration dialog box.
The Collaboration Server can be set to one of the following resolutions:
●HD1060p30
●HD720p30
●SD 30
●CIF 30

Minimum Frame Rate Threshold for SD Resolution

The MINIMUM_FRAME_RATE_THRESHOLD_FOR_SD System Flag can be added and set to prevent low
quality, low frame rate video from being sent to endpoints by ensuring that an SD channel is not opened at
frame rates below the specified value. For more information see Modifying System Flags on page 754.
Additional Video Resolutions
The following higher video quality resolutions are available:
●CIF 352 x 288 pixels at 50 fps.
●WCIF 512 x 288 pixels at 50 fps.
●WSD 848 x 480 pixels at 50 fps.
●W4CIF 1024 x 576 pixels at 30 fps.
●HD 720p 1280 x 720 pixels at 30fps.
●HD 1080p 1920 x 1080 pixels at 30 fps.
w448p Resolution
For improved interoperability with Tandberg MXP 990/3000 endpoints, the appropriate System Flag settings
will force the Collaboration Server to send w448p (768x448 pixels) at 25fps as a replacement resolution for
WSD15 (848x480) and SD15 (720x576 pixels).
Guidelines
●The w448p resolution is supported:
In CP mode.
The video resolution transmitted to any endpoint is determined by the endpoint’s capabilities, the
conference line rate and the Conference Profile’s Motion and Sharpness settings.
