Polycom RealPresence Collaboration Server 800s Getting Started Guide
1-6 Polycom, Inc.
For more information see the Polycom® RealPresence Collaboration Server 800s Administrator’s
Guide, "Video Resolutions in AVC-based CP Conferencing” on page 4-1.
SVC-based Conferencing
In the Scalable Video Codec (SVC)-based conference, each SVC-enabled endpoint transmits
multiple bit streams, to the Polycom® RealPresence® Collaboration Server. Simulcasting
enables each endpoint to transmit at different resolutions and frame rates such as 720p at
30fps, 15fps, and 7.5fps, 360p at 15fps and 7.5fps, and 180p at 7.5fps.
Using the SVC video protocol, SVC conferences relays the received video streams to the
SVC-enabled endpoints at different resolutions, frame rates and line rates according to the
endpoint’s display capabilities and layout configurations without sending the entire video
layout to the endpoints.
For more details, see Polycom® RealPresence Collaboration Server 800s Administrator’s Guide,
"SVC-based Conferencing” on page 2-9.
H.239
The H.239 protocol allows compliant endpoints to share content. By default, all Conferences,
Entry Queues, and Meeting Rooms launched on the Collaboration Server have H.239
capability.
For more details, see Polycom® RealPresence Collaboration Server 800s Administrator’s Guide,
"Content Sharing” on page 3-1.
IVR-Enabled Conferencing
Interactive Voice Response (IVR) is a software module that automates the connection
process and lets participants perform various operations during ongoing conferences. The
participants use their endpoints’ keypads, remote controls and touch control devices to
interact with the conference’s menu-driven scripts using DTMF codes.
Operations that can be performed by participants or chairpersons during a conference
include:
• Mute or unmute the participant’s audio channel.
• Play the Help menu.
• Mute or unmute undefined dial-in participants upon their connection to the conference.
• Secure and unsecure a conference.
• Request individual and conference assistance (CP conferences).
• Manually terminate the conference.
For more details, see Polycom® RealPresence Collaboration Server 800s Administrator’s Guide,
"IVR Services” on page 17-1.
Entry Queue
An Entry Queue is a special routing lobby for video and audio participants. After dialing the
Entry Queue ID, voice prompts from an IVR service are used to connect the participants to
the appropriate conference.
