Chapter 3-Video Protocols and Resolution Configuration for CP Conferencing

Polycom, Inc.

Endpoints will connect at resolutions as set out in the following table, depending on 

whether they support H.264 High Profile or not:

The following higher video quality resolutions are available when the RMX is working in 

MPM+ or MPMx Mode:
•

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 60 fps (symmetric with MPMx).

•

HD 1080p 1920 x 1080 pixels at 30 fps (symmetric with MPMx).

•

HD 1080p 1920 x 1080 pixels at 60 fps (symmetric with MPMx). 

For improved interoperability with Tandberg MXP 990/3000 endpoints, the appropriate 

System Flag settings, will force the RMX to send w448p (768x448 pixels) at 25fps as a 

replacement resolution for WSD15 (848x480) and SD15 (720x576 pixels).

•

The w448p resolution is supported:
—

In MPMx card configuration mode.

—

In CP mode.

—

At conference line rates of 384kbps and 512kbps.

The video resolution transmitted to any endpoint is determined by the endpoint’s capabilities, the 
conference line rate, the Conference Profile’s Motion and Sharpness settings and the RMX’s Card 
Configuration Mode (MPM+ or MPMx).
