Video Protocols and Resolution Configuration for CP Conferencing
Polycom®, Inc. 112
HD1080p60 Resolution Guidelines
HD1080p60 resolution is supported in Continuous Presence (CP) mode:
● With MPMx media cards:
Asymmetrically: The Collaboration Server receives HD720p60 and sends HD1080p60.
In both Video Quality modes (Motion or Sharpness).
With line rates between 2Mbps and up to 4 Mbps (the maximum line rate available for CP
conferences).
● With MPMRx media cards / RMX1800:
Symmetrically: The Collaboration Server receives and sends HD1080p60.
With Video Quality mode set to Motion.
For H.323 and SIP participants.
At line rates up to 4Mbps.
RMX1800-0 only supports HD1080p60 symmetric video when Video Quality is set as Motion in
the conference Profile.
HD1080p60 resolution is supported in Video Switching (VSW) mode:
At bit rates of up to 6Mbps.
HD1080p60 is supported symmetrically: The RMX receives and sends HD1080p60.
HD1080p60 resolution is not supported:
For ISDN participants.
With RTV video protocol.
HD1080p60 resolution is not supported symmetrically:
In 1X1 layouts, including 1X1 layouts in Telepresence Mode. Instead, the Collaboration Server
transmits the current speaker endpoint’s video resolution and frames per second.
In TIP environments.
In Telepresence environments the RMX receives HD720p60 and sends HD1080p60 to all endpoints except
for those with 1x1 Video Layouts, which receive the same resolution and frame rate from the RMX as they
send. TIP endpoints are not supported.
PAL endpoints are supported at a frame rate of 50 fps.
