RealPresence Collaboration Server Main Features

The RealPresence collaboration server offers:

Conferencing Modes

The MCU system offers the following types of conferences (Conferencing Modes), based on the video
protocol and the video display during the conference:
● AVC-based Conferencing - CP Only (Video Transcoding)
● AVC-based Conferencing - Video Switching (Collaboration Server (RMX) 1500/2000/4000 only)
● SVC-based Conferencing (Media Relay) - SVC Only
● Mixed AVC and SVC Conferencing - CP and SVC

AVC-based Conferencing

AVC-based Conferences allow endpoints that support AVC video to connect to these conferences. AVC
(Advanced Video Coding) video refers to the H.264 video protocols used to send and receive video. On the
Collaboration Server system it also includes all the standard video protocols such as H.261, H.263, and
RTV.
All endpoints (including SVC-enabled endpoints) have AVC capabilities and can connect to AVC
conferences running on the MCU. AVC-based endpoints can connect using different signaling protocols and
different video protocols.
Based on the video processing required during the conference, the Collaboration Server offers the
Continuous Presence Video Session Type for AVC-based conferencing.
In the Collaboration Server (RMX) 1500/2000/4000, the MCU also offers the Video Switching conferencing
Mode. Video Switching is not supported with Collaboration Server (RMX) 1800.
The Conferencing Mode determines the video display options (full screen or split screen with all participants
viewed simultaneously) and the method in which the video is processed by the MCU (with or without using
the MCU's video resources).
CP Only (CP Transcoding) - AVC-based Conferencing
A transcoded CP (Continuous Presence) conference is also described as an AVC (Advanced Video Coding)
conference. It supports the standard video protocols. In this mode, video is received from all the endpoints
using different line rates, different transport protocols (SIP, H.323, PSTN and ISDN) and video parameters:
● Video protocols: H.261, H.263, H.264 Base and High profile and RTV
● Video Resolutions: from QCIF, CIF and up to 1080p60
● Frame rates up to 60fps
By default every conference, Entry Queue and Meeting Room has the ability to declare the maximum CP
resolution as defined for the system.
The MCU processes the received video, transcodes it and sends the resulting video streams to the
endpoints.
The Continuous Presence (CP) conference enables viewing flexibility by offering multiple viewing options
and video cell layouts for video conferencing.
