Chapter 3-Video Protocols and Resolution Configuration for CP Conferencing
Polycom, Inc. 3-21
Endpoints will connect at resolutions as set out in the following table, depending on
whether they support H.264 High Profile or not:
Additional Video Resolutions in MPM+/MPMx Card
Configuration Mode
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).
w448p Resolution
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).
Guidelines
•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).
