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).
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).
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.
— With H.323, SIP and ISDN endpoints.
H.323 endpoints must identify themselves as Tandberg MXP during capabilities
exchange.
— In all Video Layouts.
— In 1x1 Layout:
• When Video Clarity is Off, the RMX transmits the same resolution as it
receives.
• When Video Clarity is On, the RMX changes the transmitted resolution to
w448p.
For more information see "Video Clarity” on page 1-18.
• Resource consumption for the w448p resolution is the same as for SD and WSD
resolutions, with each MPMx-D card supporting up to 60 w448p participants.
