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:
•
•
•
•
•
•
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).

Additional Intermediate Video Resolutions

Two higher quality, intermediate video resolutions replace the transmission of CIF (352 x
288 pixels) or SIF (352 x 240 pixels) resolutions to endpoints that have capabilities between:
•
•
The frame rates (depending on the endpoint's capability) for both intermediate resolutions
are:
•
In MPM+ / MPMx Mode – 50 or 60 fps.

Video Display with CIF, SD and HD Video Connections

Although any combination of CIF, SD and HD connections is supported in all CP
conferences, the following rules apply:
•
•
•
Polycom, Inc.
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).
CIF (352 x 288 pixels) and 4CIF (704 x 576 pixels) – the resolution transmitted to these
endpoints is 432 x 336 pixels.
SIF (352 x 240 pixels) and 4SIF (704 x 480 pixels) – the resolution transmitted to these
endpoints is 480 x 352 pixels.
In MPM Mode – 25 or 30 fps.
In a 1X1 Video Layout:
— SD: If the speaker transmits CIF, the MCU will send CIF to all participants,
including the SD participants. In any other layout the MCU will transmit to each
participant at the participant's sending resolution.
— HD: The MCU transmits speaker resolution (including input from HD
participants) at up to SD resolution. If 1x1 is the requested layout for the entire
duration of the conference, set the conference to HD Video Switching mode.
In asymmetrical Video Layouts:
— SD: A participant in the large frame that sends CIF is displayed in CIF.
— HD: Where participants' video windows are different sizes, the RMX transmits HD
and receives SD or lower resolutions.
In panoramic Video Layouts:
— SD: Participants that send CIF also receive CIF.
— HD: the RMX transmits HD and receives SD or lower resolutions, the RMX scales
images from SD to HD resolution.
