RMX 1500/2000/4000 Release Notes for Maximum Security Environments - Version 7.5.0.J

Resolution Configuration
In previous versions, video resolutions for participants were determined according to a
predefined video resolution decision matrix. The decision matrix matched video
resolutions to connection line rates, with the aim of providing the best balance between
resource usage and video quality at any given line rate.
Version 7.0
The Resolution Configuration dialog box enabled the RMX administrator to override the
default video resolution decision matrix, effectively creating his/her own decision
matrix. The minimum threshold line rates at which endpoints are connected at the
various video resolutions could be optimized by adjusting the resolution sliders.
Version 7.0.1
Version 7.0.1 incorporated System Flags allowing the administrator to modify the
minimum bit rate thresholds to prevent potential video quality issues when using
endpoints that do not support H.264 High Profile.
For more information see "Flags used in Version 7.0.1” on page69.
Version 7.0.2
Version 7.0.2 incorporates these System Flags into a Resolution Configuration dialog box
designed to enable the administrator to modify the minimum bit rate thresholds to
prevent potential video quality issues when using endpoints that do not support H.264
High Profile.
Card Configuration Mode
Version 7.0.2 displays the Resolution Configuration dialog box according to the Card
Configuration Mode of the RMX: MPM+ or MPMx.
Guidelines
• Resolution Slider settings affect all Continuous Presence (CP) conferences running on
the RMX. Video Switched conferences are not affected.
• A system restart is not needed after changing the Resolution Slider settings.
• Resolution Slider settings cannot be changed if there are ongoing conferences
running on the RMX.
• The displayed sliders and the resolutions change according the Card Configuration
Mode: MPM+ or MPMx.
Accessing the Resolution Configuration dialog box
The Resolution Configuration dialog box is accessed by clicking Setup > Resolution
Configuration in the RMX Setup menu.
The Resolution Configuration dialog box display changes according to the Card
Configuration Mode:
• MPM+
• MPMx - supports H.264 High Profile
• 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).
• The frames per second (fps) values listed for the video resolutions above are the maximum
possible and may be adjusted downward depending on available bandwidth.
