HD1080p60 Resolution Guidelines
HD1080p60 resolution is supported in Continuous Presence (CP) mode:
● 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.
RMX 1800 with no DSP cards 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.
