Hd1080P60 Resolution Guidelines; Cp Conferencing With H.263 4Cif - Polycom 1500 Administrator's Manual

RealPresence Collaboration Server (RMX) 1500/1800/2000/4000 Administrator's Guide

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:
 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.
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.
 For Content sharing.
 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.

CP Conferencing with H.263 4CIF

The video resolution of 4CIF in H.263 endpoints is only supported for conferences in which the video quality
is set to sharpness and for line rates of 384 Kbps to 1920 Kbps as shown in the following table.
