Polycom RealPresence Collaboration Server 800s Getting Started Guide
1-4 Polycom, Inc.
The Polycom RealPresence Collaboration Server 800s unit can be controlled via the LAN, by
the Collaboration Server Web Client application, using Internet Explorer installed on the
user’s workstation or the RMX Manager application. The RMX Manager can control
several MCU units. For more information about the RMX Manager, see "RMX Manager
Application” on page 19-1.
MCU management and IP conferencing are performed via two different LAN ports. The
networks can be separated in Maximum Security Environments.Management and IP Service
can be combined in one LAN port or separate to different ports.
RealPresence Collaboration Server Main Features
Conferencing Modes
The MCU system offers the following Conferencing Modes:
• Media Relay - SVC Conferencing
• Mixed CP and SVC Conferencing
• 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 protocols (SIP, H.323)
and video parameters:
• Video protocols: H.263, H.264 Base and High profile and RTV
• Video Resolutions: from QCIF, CIF and up to 720p
• Frame rates up to 3060fps
All endpoints that do not support the H.264 SVC protocol such as H.263, and H.264, or RTV,
are considered AVC endpoints.
The MCU process the received video, transcodes it and send the resulting video streams to
the endpoints. The video processing that is required differs according to the video session
set for the conference, with all the processing performed by the MCU. For more details, see
Polycom® RealPresence Collaboration Server 800s Administrator’s Guide, "AVC Conferencing -
Video Session Types” on page 2-4.
Media Relay - SVC Conferencing
Media Relay SVC Conferencing is based on the Scalable Video Coding (SVC) video protocol
and SAC Polycom's proprietary Scalable Audio Coding protocol. It offers high resolution
video conferencing with low end-to-end latency, improved Error Resiliency and higher
system capacities.
The Polycom multipoint media server, serves as an integrated media relay engine that
provides media streams for displaying conferences at low latency video experience in video
conferences. For more details, see Polycom® RealPresence Collaboration Server 800s
Administrator’s Guide, "SVC-based Conferencing” on page 2-9.
Mixed CP and SVC Conferencing
This type of conference enables participants with SVC-enabled endpoints and AVC
endpoints to participate in the same conference.
Each endpoint connects according to its capabilities. The MCU processes the AVC video
streams and converts them into SVC video Streams and relays them to the SVC participants
that constructs the video layout on the endpoint.
