Conference Profiles
Profiles stored on the MCU enable you to define all types of conferences. Profiles include
conference parameters such as Conferencing Mode, Conference Session Type, Conference
Line Rate, Video Layout, Encryption, Lost Packet Recovery etc.
The maximum number of Conference Profiles that can be defined is 80.
Conference Profiles are assigned to Conferences, Meeting Rooms, Reservations and Entry
Queues. The same Profile can be assigned to different conferencing entities. When modifying
the Profile parameters, the changes will be applied to all the conferencing entities to which
the profile is assigned.
Conference Profile options differ according to the selected Conferencing Mode and Conference
Type. Profiles can be defined for AVC (Advanced Video Codec) CP conferencing Mode or
SVC (Scalable Video Codec) conferencing Mode. AVC Conferencing Mode, offers two Video
session types: Continuous Presence (CP) conferences and Video Switching (VSW)
Conferences, and a special functional conference - Operator Conferences.
Conference Profiles can be saved to Conference Templates along with all participant parameters,
including their Personal Layout and Video Forcing settings, enabling administrators and
operators to create, save, schedule and activate identical conferences. For more information
see Chapter 11, “Using Conference Templates” .

Conferencing Modes
The MCU system offers the following Conferencing Modes:
•Transcoding - AVC Conferencing
•Media Relay - SVC Conferencing
•Mixed Mode - Mixed AVC (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 30 fps
All endpoints that do not support the H.264 SVC protocol such as H.263, 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 ,
"AVC Conferencing - Video Session Types” on page 2-4.
Polycom, Inc.2-1
Polycom® RealPresence Collaboration Server 800s Administrator’s Guide
Media Relay - SVC Conferencing
Media Relay SVC Conferencing is based on the SVC (Scalable Video Codec) video protocol
and SAC audio 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 , "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.
In the same way, the MCU processes the video streams received from the SVC participants,
converts them into AVC video and then transcodes all the video streams to compose the
video layout that is sent to the AVC endpoints.

AVC Conferencing - Video Session Types
All 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.
Continuous Presence (CP) Conferencing
The dynamic Continuous Presence (CP) capability of the Collaboration Server system
enables viewing flexibility by offering multiple viewing options and window layouts for
video conferencing.
Endpoints can connect to the conference using any signaling protocol (H.323, SIP and RTV),
line rate (up to a maximum line rate defined for the conference), Video Protocol (H.261,
H.263, H.264 Base and High Profile) and at any resolution and frame rate (provided they
meet the minimum requirements set for the conference).
In Continuous Presence conferences, the MCU receives the video stream from each
endpoint at the video rate, video resolution and frame rate that it is capable of sending, and
it superimposes all the received streams into one video stream that includes the input from
the other endpoints arranges in the selected video layout.
Participants do not see themselves in the video layout. By Default, the speaker is shown in
the top left layout cell in symmetric layouts, in the larger cell in asymmetric layouts, or in
full screen. The speaker sees the previous speakers (their number depends on the number of
cells on the speaker’s layout.
The Continuous Presence video session offers layouts to accommodate different numbers of
participants and conference settings including support of the VUI annex to the H.264
protocol for endpoints that transmit wide video instead of 4CIF resolution. Each participant
can select his/her layout for viewing during the conference, as can be seen in Figure 2-1.
For conferences with more participants than display squares, the Collaboration Server
dynamic video mix capability allows the viewed sites to be modified throughout the
conference. The displayed layout can be changed during an ongoing conference, allowing a
participant to view different screen layouts of the other conference participants. These
layout options allow conferences to have greater flexibility when displaying a large number
of participants and maximizes the screen’s effectiveness.

Chapter 2-Conference Profiles
Figure 2-1 AVC Continuous Presence (CP) video streams and built layouts
Video quality in Continuous Presence conferences is affected by the conference line rate
(that determines the maximum line rate to be used by the connecting endpoints), and the
video capabilities of the endpoints such as the video protocol, video resolution and frame
rate. Content sharing is available in all CP conferences.
This requires extensive processing of the video sent to each participant in the conference.
The higher the video rate and resolution, the more processing power is required.
By default every conference, Entry Queue and Meeting Room has the ability to declare the
maximum CP resolution as defined for the system. This includes conferences launched by
the Collaboration Server Web Client and conferences started via the API.
CP conferencing is defined in the Conference profile by settings the following main features:
•Setting the Conferencing Mode to AVC only
•Conference Line Rate
•Video Layout
Video Protocol Support in CP Conferences
The video protocol selected by the system determines the video compression standard used
by the endpoints. In Continuous Presence conferences, the system selects the best video
protocol for each of the endpoint according to he endpoint’s capabilities.
The following Video protocols are supported in CP conferences:
•H.261 - the legacy video compression algorithm mandatory to all endpoints. It is used
by endpoints that do not support other protocols.
•H.263 - a video compression algorithm that provides a better video quality than H.261.
This standard is not supported by all endpoints.
Polycom, Inc.2-5
Polycom® RealPresence Collaboration Server 800s Administrator’s Guide
•H.264 Base Profile - a video compression standard that offers improved video quality,
especially at line rates lower than 384 Kbps.
H.264 High Profile allows higher quality video to be transmitted at lower line rates.
•RTV - a video protocol that provides high quality video conferencing capability to
Microsoft OCS (Office Communicator Server) endpoints at resolutions up to HD720p30.
(SIP only).
AVC Conferencing Parameters
Basic Conferencing Parameters
When defining a new video Profile, you select the parameters that determine the video
display on the participant’s endpoint and the quality of the video. When defining a new
conference Profile, the system uses default values for Continuous Presence (CP) standard
conferencing. Continuous Presence conferencing enables several participants to be viewed
simultaneously and each connected endpoint uses its highest video, audio and data
capabilities up to the maximum line rate set for the conference.
The main parameters that define the quality of a video conference are:
•Line (Bit) Rate - The transfer rate of video and audio streams. The higher the line (bit)
rate, the better the video quality.
•Audio Algorithm - The audio compression algorithm determines the quality of the
conference audio.
•Video protocol, video format, frame rate, annexes, and interlaced video mode - These
parameters define the quality of the video images. The Collaboration Server will send
video at the best possible resolution supported by endpoints regardless of the
resolution received from the endpoints.
— When Sharpness is selected as the Video Quality setting in the Conference Profile, the
Collaboration Server will send 4CIF (H.263) at 15fps instead of CIF (H.264) at 30fps.
— H.264 High Profile protocol provides better compression of video images in line
rates lower than 384 Kbps and it will be automatically selected for the endpoint if it
supports H.264 High Profile. If the endpoint does not support H.264 High Profile,
the Collaboration Server will try H.264 Base Profile which provides good
compression of video images in line rates lower than 384 Kbps (better than H.263
and not as good as H.264 High Profile).
— When working with Collaboration Servers at low bit rates (128, 256, or 384Kbps),
HDX endpoints will transmit SD15 resolution instead of 2CIF resolution.
When using a full screen (1x1) conference layout, the Collaboration Server transmits the
same resolution it receives from the endpoint.
•Lost Packet Recovery (LPR) - LPR creates additional packets that contain recovery
information used to reconstruct packets that are lost during transmission.
•Supported resolutions:
— H.261 CIF/QCIF – Is supported in Continuous Presence (CP) conferences at
resolutions of 288 x 352 pixels (CIF) and 144 x 176 pixels (QCIF). Both resolutions
are supported at frame rates of up to 30 frames per second.
— H.263 4CIF - A high video resolution available to H.263 endpoints that do not
support H.264. It is only supported for conferences in which the video quality is set
to sharpness and for lines rates of 384kbps to 1920kbps.
2-6Polycom, Inc.
Chapter 2-Conference Profiles
— Standard Definition (SD) - A high quality video protocol which uses the H.264
and H.264 High Profile video algorithms. It enables compliant endpoints to
connect to Continuous Presence conferences at resolutions of 720 x 576 pixels for
PAL systems and 720 x 480 pixels for NTSC systems. For more information, see
"Video Resolutions in AVC-based CP Conferencing” on page 4-1.
— High Definition (HD) – HD is an ultra-high quality video resolution that uses he
H.264 and H.264 High Profile video algorithms. Depending on the Collaboration
Server’s Card Configuration mode compliant endpoints are able to connect to
conferences at the following resolutions:
•720p (1280 x 720 pixels)
For more information, see "Video Resolutions in AVC-based CP Conferencing” on
page 4-1.
Supplemental Conferencing Features
In addition to Standard Conferencing the following features can be enabled:
•Content Sharing (H.239) – Allows compliant endpoints to transmit and receive two
simultaneous streams of conference data to enable Content sharing. H.239 is also
supported in cascading conferences. Both H.263 and H.264 Content sharing protocols
are supported. If all endpoints connected to the conference have H.264 capability,
Content is shared using H.264, otherwise Content is shared using H.263.
For more information, see "Content Sharing” on page 3-1.
•Lecture Mode – The lecturer is seen by all participants in full screen while the lecturer
views all conference participants in the selected video layout.
For more information, see "Lecture Mode (AVC CP Only)” on page 3-42.
•Presentation Mode (CP Conferences only) – When the current speaker’s speech
exceeds a predefined time (30 seconds), the conference layout automatically changes to
full screen, displaying the current speaker as the conference lecturer on all the
participants’ endpoints. During this time the speaker’s endpoint displays the previous
conference layout. When another participant starts talking, the Presentation Mode is
cancelled and the conference returns to its predefined video layout. Presentation mode
is available with Auto Layout and Same Layout.
— If the speaker in a video conference is an Audio Only participant, the Presentation
Mode is disabled for that participant.
— Video forcing works in the same way as in Lecture Mode when Presentation Mode
is activated, that is, forcing is only enabled at the conference level, and it only
applies to the video layout viewed by the lecturer.
•Encryption – Used to enhance media security at conference and participant levels. For
more information, see "Audio Algorithm Support” on page 3-25.
•Conference Recording - The Collaboration Server enables audio and video recording of
conferences using Polycom RSS recording system.

SVC-based Conferencing
The SVC-Based conferencing mode provides video without transcoding by the MCU, hence
requiring less video resources while providing better error resiliency and lower latency.
Using the SVC video protocol, SVC conferences provide video bit streams at different
resolutions, frame rates and line rates to SVC-enabled endpoints with various display
capabilities and layout configurations.
In the SVC-based conference, each SVC-enabled endpoint transmits multiple bit streams,
called simulcasting, 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.
The Polycom SVC-enabled endpoints (such as Polycom® RealPresence® Desktop and
Polycom® RealPresence® Mobile) compose the layout according to their layout settings and
video capabilities. This enables the MCU to send or relay the selected video streams to each
endpoint without processing the video streams and sending the composite video layout to
the endpoints.
Chapter 2-Conference Profiles
-
Figure 2-2 SVC video streams and Layouts
The video streams displayed in the conference layout on each endpoint is obtained from the
different streams received from each of the endpoints displayed in the layout. Depending on
the size of the video cell in the configured layout, the endpoint requests the video stream in
the required resolution from the RealPresence Collaboration Server. The higher the display
quality and size, the higher the requested resolution will be sent to the endpoint. The
endpoint creates the displayed layout from the different video streams it receives.
Polycom, Inc.2-9
Polycom® RealPresence Collaboration Server 800s Administrator’s Guide
For instance, an SVC endpoint might want to receive three video streams at different frame
rates and resolutions, and create a conference layout with the received video streams. Each
SVC-enabled endpoint sends encoded SVC bit streams to the MCU to relay to the other
SVC-enabled endpoints in the conference.
The endpoints encode the video in multiple resolutions and decodes the multiple video
input streams.
For example:
RealPresence mobile client (2) will transmit two resolutions; one that is suited for
RealPresence Desktop client (3) and a second that is suited for two other endpoints:
RealPresence Desktop client (4) and (1).
RealPresence Desktop client (1) transmits two resolutions; one that is suited for
RealPresence Mobile client (2) and a second that is suited for RealPresence Desktop
client (4).
The MCU determines which of the incoming resolutions to send to each endpoint. It does
not perform any SVC encoding and decoding, or any transcoding of the video streams. The
RealPresence Collaboration Server functions as the multipoint media relay to the endpoints.
For voice activated selection of the video streams, the RealPresence Collaboration Server
determines which of the incoming bit streams to send to each endpoint.
Advantages of SVC Conferencing
SVC increases the scalability of video networks and enables mass desktop video
deployments. Some of the advantages of SVC conferencing are:
•Offers high-resolution video conferencing with low end-to-end latency, improved error
resiliency and higher system capacities.
•Allows the SVC-enabled video endpoints to manage display layouts, supporting
multiple line rates, resolutions and frame rates.
•The RealPresence Collaboration Server functions as a media relay server providing low
cost production benefits. The RealPresence Collaboration Server reduces bandwidth
usage by only selecting the necessary video stream to be sent to the endpoints.
Guidelines
•SVC conferences are supported only with the following:
•SVC Only conferences can run on the same MCU as AVC Only conferences.
•End-to-end latency on a local network (same site), is around 200mSec to ensure AV
sync (also known as Lip-sync).
•Dial-out is not available in SVC Only conference.
•Dial-in is available as follows:
— AVC endpoints (participants) can only connect to an AVC conference or Mixed CO
and SVC conference. When dialing into SVC Only conferences they will be
disconnected and the calls fail.
2-10Polycom, Inc.
Chapter 2-Conference Profiles
— SVC endpoints support both AVC and SVC video protocols.
When dialing into SVC Only conferences, they connect as SVC endpoints.
When dialing into AVC Only conferences, they connect as AVC endpoints. They
cannot connect to an AVC conference using the SVC capabilities.
•SVC endpoints cannot be moved between conferences.
•Content is supported in H.264 (AVC).
— Only the H.264 Cascade and SVC Optimized option is supported.
— LPR and DBA are not supported for SVC content sharing.
•In SVC Only conferences and Mixed CP and SVC conferences, Auto Layout is the
default and the layout display for SVC endpoints is controlled from the endpoint
application.
•Site names display on SVC endpoints is controlled from the SVC endpoints.
•When DMA is part of the solution, the DMA is used as the SIP proxy and the SVC
endpoint subscribes to DMA for call control. If a DMA is not part of the solution, the
SVC endpoint dial directly to the Collaboration Server using IP addresses is the SIP
dialing strings.
•When Hot backup is enabled, all the conferences are created on the Slave MCU.
•When Hot Backup is activated and the Slave MCU becomes the Master MCU:
— All AVC endpoints will be reconnected to the AVC conferences. SVC endpoints
connected to AVC conferences using their AVC capabilities will be reconnected to
their AVC conferences.
— SVC endpoints cannot be reconnected to their SVC Only conferences as dial-out is
not supported for SVC endpoints. These endpoints will have to manually
reconnect to their SVC conferences.
•Cascading between SVC Only conferences or between AVC and SVC Only conferences
is not supported.
•The following functionality and features are not supported during SVC Only
conferences:
— FECC
— Skins. The video cells are displayed on the endpoint’s default background.
— Conference Gathering phase
— Password protected conferences as DTMF input for passwords cannot be
processed
— Manual selection of video layout
— Recording of SVC Only conferences
— Text messaging using Message Overlay

MCU Supported Resolutions for SVC Conferencing
The MCU automatically selects the resolution and frame rate according to the conference
line rate. Table 2-3 details the maximum resolution and frame rates supported by the MCU
for each conference line rate. The actual video rate, resolution and frame rates displayed on
each endpoints is determined by the endpoint’s capabilities.:

Mixed CP and SVC Conferencing
In a Mixed CP and SVC conference, SVC endpoints transmit multiple resolutions and
temporal layers to the Collaboration Server like the SVC-based conferences, while AVC
endpoints send only one H.264 AVC video stream to the Collaboration Server. The
Collaboration Server relays SVC-decoded video bit streams to the SVC-enabled endpoints in
the conference according to their display capabilities. This enables the video conference
layouts to be automatically assembled by the endpoint. AVC endpoints connected to the
conference send a single H.264 AVC video bit stream to the Collaboration Server, which is
then transcoded to SVC video streams. SVC-enabled endpoints receive the AVC converted
video bit streams through the Collaboration Server from the AVC endpoints as a single SVC
video bit stream. Alternatively, AVC endpoints receive a single video bit stream with the
defined video conference layout from the Collaboration Server. In this mixed mode
conferencing, both SVC and AVC endpoints in the conference receive the same CP layout.
Polycom, Inc.2-13
Polycom® RealPresence Collaboration Server 800s Administrator’s Guide
The following diagram illustrates an example of a mixed AVC/SVC conferencing mode:
In this example, an SVC endpoint (1) receives three video streams at different frame rates
and resolutions, and creates the conference layout with the received video streams. The
video bit stream that the SVC endpoint receives from the AVC endpoint (3) is transcoded in
the Collaboration Server and then encoded into an SVC bit stream in the required
resolution.
Alternatively, an AVC endpoint (4) sends a single resolution video stream to the
Collaboration Server. The Collaboration Server first converts the SVC bit stream into AVC,
then transcodes the video received from the other endpoints to the required resolution. The
Collaboration Server composes the video layout for the AVC endpoint and sends a single
resolution video stream with the video layout to the participant. In the displayed example,
the Collaboration Server creates different video layouts for each AVC endpoint.
Default Profile Settings in Mixed CP and SVC Conferencing Mode
The Collaboration Server is shipped with a default Conference Profile for Mixed CP and SVC
conferences which allows users to immediately start a standard ongoing Mixed CP and SVC
conference. These are also the default settings when creating a new Profile.

Profiles are the basis for the definition of all ongoing conferences, Reservations, Meeting
Rooms, Entry Queues, and Conference Templates and they contain only conference properties.
Conference Profile options differ according to the selected Conferencing Mode and Conference
Type. Profiles can be defined for AVC (Advanced Video Codec) conferencing Mode or SVC
(Scalable Video Codec) conferencing Mode.
AVC Conferencing Mode offers the following Video session types: Continuous Presence
(CP) conferences, Mixed CP and SVC conferences, and a special functional conference Operator Conferences in CP mode.

In layout 2+8, the two central windows display the last two speakers in the conference:
the current speaker and the “previous” speaker. To minimize the changes in the layout,
when a new speaker is identified the “previous” speaker is replaced by the new speaker
while the current speaker remains in his/her window.
The Collaboration Server supports the VUI addition to the H.264 protocol for endpoints that transmit
wide video (16:9) in standard 4SIF resolution.
When there is a change of speaker in a Continuous Presence conference, the transition is set by
default to fade in the current speaker while fading out the previous speaker.
To make this transition visually pleasant, fading in the current speaker while fading out the previous
speaker is done over a period of 500 milliseconds.
The Fade In / Fade Out feature can be disabled by adding a new flag to the System Configuration.
The Value of the new flag must be: FADE_IN_FADE_OUT=NO.

When the Mute Participants Except Lecturer option is enabled, the
audio of all participants in the conference except for the lecturer can
be automatically muted upon connection to the conference. This
prevents other conference participants from accidentally interrupting
the lecture, or from a noisy participant affecting the audio quality of the
entire conference. Muted participants cannot unmute themselves
unless they are unmuted from the Collaboration Server Web Client/
RMX Manager.
You can enable or disable this option during the ongoing conference.
Notes:
•When enabled, the mute indicator on the participant endpoints are
not visible because the mute participants was initiated by the
MCU. Therefore, it is recommended to inform the participants that
their audio is muted by using the Closed Caption or Message
Overlay functions.
In the Collaboration Server Web Client/RMX Manager the mute by
MCU indicator is listed for each muted participant in the Audio
column in the Participants pane.
•The Mute Participants Except Lecturer option can be disabled
during an ongoing conference, thereby unmuting all the
participants in the conference.
•If the endpoint of the designated lecturer is muted when the
lecturer connects to the conference, the lecturer remains muted
until the endpoint has been unmuted.
•When you replace a lecturer, the MCU automatically mutes the
previous lecturer and unmutes the new lecturer.
•When you disconnect a lecturer from the conference or the
lecturer leaves the conference, all participants remain muted but
are able to view participants in regular video layout until the you
disable the Mute Participants Except Lecturer option.
•A participant can override the Mute Participants Except Lecturer
option by activating the Mute All Except Me option using the
appropriate DTMF code, provided the participant has authorization
for this operation in the IVR Services. The lecturer audio is muted
and the participant audio is unmuted. You can reactivate the Mute Participants Except Lecturer option after a participant has
previously activated the Mute All Except Me option. The
participant is muted and the lecturer, if designated, is unmuted.

Various conferencing modes and video features require additional settings, such as system
flag settings, conference parameters and other settings. In depth explanations of these
additional settings are described in the following sections:

Content Sharing
Content such as graphics, presentations, documents or live video can be shared with
conference participants using the H.239 (H.323) or BFCP (SIP) protocol, which is the
standard protocols for content sharing.
H.239 Protocol
The H.239 protocol allows compliant endpoints to transmit and receive two simultaneous
video streams:
•People video stream – video is displayed in Continuous Presence conferences or in
Media Relay (SVC) conferencing Mode
•Content video stream – Video Switching mode for content sharing
By default, all conferences, Entry Queues, and Meeting Rooms launched on the Collaboration Server have H.239 capabilities.
To view Content, endpoints must use the same Bit Rate, Protocol, and Resolution. Endpoints
may not send Content while connecting to an Entry Queue.
Endpoints without H.239 capability can connect to the video conference without Content.
Cascade links declare H.239 capabilities and they are supported in Star cascading
topologies. For more details, see "Basic Cascading” on page 5-3.
Polycom, Inc.3-1
Polycom® RealPresence Collaboration Server 800s Administrator’s Guide
SIP BFCP Content Capabilities
SIP Clients supporting BFCP over UDP, when connected to conferences on the
Collaboration Server, can share Content with endpoints supporting the following Content
sharing protocols:
•BFCP/TCP
•BFCP/UDP
•H.323/ H.239
•H.323 /Polycom People+Content
Guidelines:
For SIP Clients that support both BFCP/TCP and BFCP/UDP:
•The preferred protocol is BFCP/UDP.
•When used in Cascading conferences, the Cascade Link must be H.323.
•BFCP/UDP is supported in both IPv4 and IPv6 addressing modes.
•BFCP utilizes an unsecured channel (port 60002/TCP) even when SIP TLS is enabled. If
security is of higher priority than SIP content sharing, SIP People+Content can be
disabled. To do this manually add the ENABLE_SIP_PEOPLE_ PLUS_CONTENTSystem Flag to the System Configuration and set its value to NO.
•SIP People+Content and BFCP capabilities are by default declared to all endpoints. If,
however, the endpoint identity is hidden by a proxy server, these capabilities will not
be declared by the Collaboration Server. Capabilities declaration is controlled by the
ENABLE_SIP_PPC_FOR_ALL_USER_AGENT System Flag.
The default value of the ENABLE_SIP_PPC_FOR_ALL_USER_AGENT System Flag is YES resulting in BFCP capability being declared with all vendors’ endpoints unless it is
set to NO. When set to NO, the Collaboration Server will declare SIP People+Content
and BFCP capabilities to
•The ENABLE_FLOW_CONTROL_REINVITE System Flag should be set to NO when SIP BFCP is enabled.
•If these System Flags don’t exist in the system, they must be manually added. For more
information see "Modifying System Flags” on page 21-1.
•BFCP capabilities are not supported in Microsoft ICE environment.
Dial-out Connections:
•For dial-out connections to SIP Clients, BFCP/UDP protocol can be given priority by
adding the adding the SIP_BFCP_DIAL_OUT_MODE System Flag to system.cfg and
setting its value to UDP.

Dial-in Connections:
•The Collaboration Server will share content with Dial-in SIP Clients according to their
preferred BFCP protocol.
•SIP Clients connected as Audio Only cannot share Content.
Defining Content Sharing Parameters for a Conference
Content can be shared using two main methods:
•Content Highest common parameters (also known as Content Video Switching)
•Multiple Content Resolutions (not supported with RealPresence Collaboration Server
800s)
In Content Video Switching mode, the content is negotiated to highest common capabilities
supported by the endpoints connected to the conference. If the conference includes
participants that support lower content capabilities (such as H.263) and higher content
capabilities (H.264), content will be sent at the lower capabilities supported by all endpoints,
resulting in lower content quality seen by all endpoints.
In this mode, the content is set according to the capabilities of all the participants currently
connected to the conference. If the all the connected participant support the H.264 protocol,
the Content will be started with H.264 capabilities. If then an endpoint supporting only
H.263 protocol connects, the content is stopped in order to switch to H.263 and has to be
resent. If the H.263 participant leaves the conference and only H.264 capable endpoints
remain connected, content is stopped in order to switch back to H.264 and has to be resent.

Content Settings
The Content channel can transmit one of the following modes:
•Graphics – for standard graphics. This is the default mode in AVC conferences and the
only supported mode for SVC conferences.
•Hi-res Graphics (AVC CP Only) – requiring a higher bit rate, for high quality display or
highly detailed graphics.
For Graphics, Hi-res Graphics and Live Video, the highest common Content bit rate is
calculated for the conference each time an endpoint connects. Therefore, if an endpoint
connects to an ongoing conference at a lower bit rate than the current bit rate, the Content
bit rate for the current conference is re-calculated and decreased.
Bit rate allocation by the MCU is dynamic during the conference and when the Content
channel closes, the video bit rate of the People conference is restored to its maximum.
During a conference the MCU will not permit an endpoint to increase its bit rate, it can
however change its Content resolution. The Collaboration Server can decrease the allocated
Content bit rate during a conference.
The following table summarizes the bit rate allocated to the Content channel from the video
channel in each of the Content Settings according to the conference line rate:

Content Protocols
Two Content Protocols can be used for sharing content:
•H.263 (CP and mixed CP and SVC)
•H.264 (all conferencing modes)
H.264 offers higher quality content, but is not supported by legacy endpoints. Depending on
the endpoints capabilities, you can determine the content sharing experience by selecting
the appropriate protocol and system behavior from the Content Protocol list:
•H.263 & H.264 Auto Selection
•H.263
•H.264 HD
(AVC CP Only)
(AVC CP Only)
•H.264 Cascade and SVC Optimized (all conferences)
(AVC CP Only)
H.263 & H.264 Auto Selection (AVC CP Default)
The H.263 & H.264 Auto Selection option should be selected when Content is to be shared
using a mix of H.263-supporting and H.264-supporting endpoints.
Bit rate allocation to the Content channel by the Collaboration Server is dynamic according
to the conference line rate and Content Setting selected for the conference.
If an endpoint that supports only H.263 for Content Sharing connects to a conference with
Content Protocol set to H.263 & H.264 Auto Selection:
•Content is shared using H.263 even if H.264-supporting endpoints are connected.
•Content is shared using H.264 if all connected endpoints have H.264 capability.
•If the first endpoint to connect to the conference only supports H.263, the H.263 protocol
is used for Content for all conference participants.
•If Content is already being shared using the H.264 protocol when a H.263 endpoint
connects, Content sharing is stopped and must be manually restarted using H.263 (i.e.
the endpoint using H.263 Content Protocol must connect first), for all participants to
receive content. If the H.263 endpoint disconnects, Content sharing must be manually
stopped and restarted and will automatically upgrade to the H.264 protocol.
•Endpoints that do not have at least H.263 capability can connect to the conference but
cannot share Content.
•This option is not available in SVC Conferencing Mode and CP and SVC Conferencing Mode.
3-8Polycom, Inc.
Chapter 3-Additional Conferencing Information
H.263 (AVC CP Conferences)
Select this option when most of the endpoints support H.263 and some endpoints support
H.264. In such a case, all endpoints will share content using the H.263 protocol, and this
protocol will not change throughout the conference (fixed mode).
Bit rate allocation to the Content channel by the Collaboration Server is dynamic according
to the conference line rate and Content Settings selected for the conference. For more
information see "Content Sharing Parameters in Content Highest Common (Content Video Switching) Mode” on page 3-6.
This option is not available in SVC Conferencing Mode and CP and SVC Conferencing Mode.
H.264 HD (AVC CP Conferences)
The H.264 HD option should be selected only if most endpoints in the conference support
H.264 to ensure high quality Content.
When this protocol option is selected, endpoints must connect at Content bit rates above a
minimum as specified by specific System Flags to ensure high quality Content for all
participants. For more information about System Flags see "Setting the Minimum Content Rate for Each Content Quality Setting for H.264 HD” on page 3-10.
Bit rate allocation to the Content channel by the Collaboration Server is dynamic according
to the conference line rate and Content Setting selected for the conference. For more
information see "Content Sharing Parameters in Content Highest Common (Content Video Switching) Mode” on page 3-6.
Endpoints that do not support H.264, or those that do not meet the minimum line rate
threshold for the Content Settingwill not receive content.
Guidelines
•Only endpoints that support H.264 capability at a resolutions of HD720p5 or higher will
be able to receive and send Content.
•This option is not available in SVC Conferencing Mode and CP and SVC Conferencing Mode.
•Maximum supported content resolution is HD 720p.
•The minimum Content Rate required for allowing a participant to share Content is the
lower valued parameter when comparing the System Flag setting (Table 3-7)

rate allocation derived from the conference line rate (Table 3-8).
and the
When the flag settings enable an endpoint to share Content at a content rate that is
lower than the conference content rate (Table 3-8), the content rate of the entire
conference is reduced to the content rate supported by that endpoint.
Setting the Minimum Content Rate for Each Content Quality Setting for H.264 HD
The following System Flags determine the minimum content rate required for endpoints to
share H.264 high quality content via the Content channel.
A System Flag determines the minimum line rate for each Content Setting:
•Graphics
•Hi Resolution Graphics
•Live Video
Polycom, Inc.3-9

H.264 Cascade and SVC Optimized
The H.264 Cascade and SVC Optimized option maintains content quality and minimizes
the amount of content refreshes that occur in large cascading conferences when participants
connect or disconnect from the conference.
This option is the only available option automatically selected in SVC Only conferencing Mode and mixed CP and SVC Conferencing Mode.
The H.264 Cascade and SVC Optimized option uses fixed resolution and frame rate for SVC Only and mixed CP and SVC conferences. In AVC CP conferences, each content Line Rate
and Content Setting has its own resolution and frame rate as summarized in Table 3-12.
In AVC CP conferences, endpoints that do not support the required content parameters
(Content line rate, H.264 protocol and Content Resolution), will not receive content.
Endpoints that do not support the required content parameters (Content line rate and Content Resolution) cannot share content.
Guidelines
•In Cascading conferences, the cascade link must be H.323.
•This is the only available Content sharing mode in SVC Conferencing Mode and CP and SVC Conferencing Mode.
•H.264 High Profile is not supported.

Enabling H.264 Cascade and SVC Optimized Content Sharing in AVC CP Conferences
When H.264 Cascade and SVC Optimized is selected as the Content Protocol, an additional
field, Content Resolution is displayed in the Content Video Definition pane.
In SVC Conferencing Mode and CP and SVC Conferencing Mode, the Content Resolution option
is disabled.
The Content Resolution is a fixed resolution and frame rate for Content sharing in a Cascaded
Conference. The Content Resolution that are available for selection are dependent on the Line Rate and Content Settings that have been selected for the conference.
The following table summarizes the interaction of these parameters.
The selection of the appropriate Content Resolution option, when several options are
available, should be based on the line rate and capabilities that can be used by most or all
endpoints connecting to the conference.
Examples:
•If the conference Line Rate is 1024 kbps.
and
•If the Content Settings selection is Graphics.
— Content Resolutions of HD720/5 and HD1080/15 are selectable with 256 kbps and
768 kbps allocated as the Conference Content Rate respectively.
The higherContent Resolution, HD1080/15 should be selected only if most of the
endpoints connecting to the conference can support a Content Rate of 768Kbps,
which requires the participant to connect to the conference at a Line Rate of
1024kbps.
3-12Polycom, Inc.
Chapter 3-Additional Conferencing Information
When the lower Content Resolution HD720/5 is selected, the conference Content Rate
is set to 256 kbps. This will enable the endpoints that connect to the conference at a
Line Rate of at least 768 kbps to receive content in the Content channel. Endpoints
that connect to the conference at a line rate lower than 768Kbps, will not receive
content.
•If the Content Settings selection is Hi Resolution Graphics.
— Only HD720/5 can be selected as the Content Resolution with 384 kbps allocated as
the conference Content Rate.
Only endpoints that connect at a Line Rate of 768 kbps that is required to support a
Content Rate of 384 kbps will receive content in the Content channel. Endpoints that
connect to the conference at a line rate lower than 768 kbps, will not receive
content.
•If the Content Settings selection is Live Video.
HD720/5, HD720/30 or HD1080/15 can be selected as the Content Resolution with
768 kbps allocated the as the Conference Content Rate. The higher Content Resolution
should be selected according to the resolution capabilities of the majority of the
endpoints connecting to the conference. Endpoints that cannot support the selected
Content Resolution are considered Legacy Endpoints and will not receive content.
Selecting a Customized Content Rate in AVC CP Conferences
Customized Content Rate functionality can be implemented when a ConferenceContent Rate,
that is automatically calculated by the Collaboration Server, may not be suitable in a
Cascaded Environment, where conference line rates may vary widely between the cascaded
conferences. For example, one conference may have a line rate of 2 Mbps, and the other a
line rate of is 512kbps.
Guidelines:
•Cascaded conferences may have different Conference Line Rates.
•The Customized Content Rate must be the same for all cascaded conferences.
Polycom, Inc.3-13
Polycom® RealPresence Collaboration Server 800s Administrator’s Guide
To Select the Customized Content Rate:
Customized Content Rate is enabled in the Profile - Video Quality dialog box.
1In the Content Settings list, select Customized Content Rate.
When selected, a drop-down menu of the available Conference Content Rates is
displayed. These Content Line Rates are based on and will vary according to the selected
Conference Line Rate.
The largest selectable Content Line Rate is 66% of the Conference Line Rate.
If the Conference Line Rate is 64kbps or 96kbps, the only available Conference Content Rate
is 0, indicating that Content is not supported at these rates.
2Select the required content rate.
When selecting a Conference Line Rate (after selecting Customized Content Rate) that is too
low for the selected Customized Content Rate, the following error message is displayed:
“The selected content line rate should be modified. To update content line rate press Cancel. To
return to automatic mode (Graphics) press OK.”
You can then modify either the Content Line Rate or the Conference Line Rate or select
another Content Setting option.

•In Exclusive Content Mode, if an endpoint attempts to send Content a few seconds after
another endpoint sent Content, the Content stream it is receiving is momentarily
interrupted by a slide which is displayed for a few seconds before the normal Content
stream is resumed.
Stopping a Content Session
In some cases, when one participant ends the Content session from his/her endpoint, the
Content token is not released and other participants cannot send Content.
The Collaboration Server User can withdraw the Content token from the current holder and
to return it to the MCU for assignment to other endpoints.
To end the current Content session:

Chapter 3-Additional Conferencing Information
Content Broadcast Control
Content Broadcast Control prevents the accidental interruption or termination of H.239
Content that is being shared in a conference.
Content Broadcast Control achieves this by giving Content Token ownership to a specific
endpoint via the Collaboration Server Web Client. Other endpoints are not able to send content
until Content Token ownership has been transferred to another endpoint via the Collaboration Server Web Client.
Guidelines
•Content Broadcast Control is supported in CP conferences.
•Content Broadcast Control is supported in H.323 environments.
•Only the selected Content Token owner may send content and Content Token requests
from other endpoints are rejected.
•Content Token ownership is valid until:
— It is canceled by the Collaboration Server User via the Collaboration Server Web
Client.
— The owner releases it.
— The endpoint of the Content Token owner disconnects from the conference.
•The Collaboration Server User can cancel Content Token ownership.
•In cascaded conferences, a participant functioning as the cascade link cannot be given
token ownership.
Polycom, Inc.3-17

Giving and Cancelling Token Ownership (AVC Participants)
To give token ownership:
1In the Participants list, right click the AVC-enabled endpoint that is to receive Content
Token ownership.
2Select Change To Content Token Owner in the drop-down menu.
The endpoint receives ownership of the Content Token and an indication icon is
displayed in the Role column of the participant’s entry in the Participants list.
To cancel token ownership:
1In the Participants list, right click the endpoint that currently has Content Token
ownership.
3-18Polycom, Inc.
2Select Cancel Content Token Owner in the drop-down menu.
Content Token ownership is cancelled for the endpoint.
Managing Noisy Content Connections
The system can identify participants who send frequent requests to refresh their Content
display usually as a result of a problematic network connection. The frequent refresh
requests cause frequent refresh of the Content display and degrade the viewing quality.
When the system identifies the noisy participants, the system will automatically suspend
the requests to refresh the sent Content to avoid affecting the quality of the Content viewed
by other conference participants. This process is controlled by System flags.
Content Display Flags
•MAX_INTRA_REQUESTS_PER_INTERVAL_CONTENT
Enter the maximum number of refresh (intra) requests for the Content channel sent by
the participant’s endpoint in a 10 seconds interval that will be dealt by the
Collaboration Server system. When this number is exceeded, the Content sent by this
participant will be identified as noisy and his/her requests to refresh the Content
display will be suspended.
Default setting: 3
Enter the duration in seconds to ignore the participant’s requests to refresh the Content
display.
Default setting: 10
•CONTENT_SPEAKER_INTRA_SUPPRESSION_IN_SECONDS
This flag controls the requests to refresh (intra) the Content sent from the Collaboration
Server system to the Content sender as a result of refresh requests initiated by other
conference participants.
Enter the interval in seconds between the Intra requests sent from the Collaboration
Server to the endpoint sending the Content to refresh the Content display. Refresh
requests that will be received from endpoints within the defined interval will be
postponed to the next interval.
Default setting: 5
Chapter 3-Additional Conferencing Information
Forcing Other Content Capabilities
•The H239_FORCE_CAPABILITIES System Flag in system.cfg gives additional control
over Content sharing:
— When the flag is set to NO (default), the Collaboration Server only verifies that the
endpoint supports the content protocols: H.263 or H.264.
— When set to YES, the Collaboration Server checks frame rate, bit rate, resolution,
annexes and all other parameters of the Content mode as declared by an endpoint
during the capabilities negotiation phase. If the endpoint does not support the
Content capabilities of the MCU, the participant will not be able to send or receive
content over a dedicated content channel.

Video Preview (AVC Only Participants)
Collaboration Server users can preview the video sent from the participant to the
conference (MCU) and the video sent from the conference to the participant. It enables the
Collaboration Server users to monitor the quality of the video sent and received by the
participant and identify possible quality degradation.
The video preview is displayed in a separate window independent to the Collaboration Server Web Client. All Web Client functionality is enabled and conference and participant
monitoring as well as all other user actions can be performed while the video preview
window is open and active. Live video is shown in the preview window as long as the
window is open. The preview window closes automatically when the conference ends or
when participant disconnects from the conference. It can also be closed manually by the
Collaboration Server user.
Video Preview Guidelines
•Video preview is available for AVC participants. It is not available for SVC participants.
•Video preview window size and resolution are adjusted to the resolution of the PC that
displays the preview.
•Video Preview of the video sent from the conference to the participant is shown
according to the line rate and video parameters of the level threshold to which the
participant is connected.
•All users can view a video preview.
•Only one preview window can be displayed for each Collaboration Server Web Client
connection (workstation).
•Only one preview window can be displayed for a single conference and up to four
preview windows can be displayed for each system on different workstations (one per
workstation and one per conference).
•Live video that is shown in the preview window does not include the Content when it
is sent by the participant.
•Video Preview is supported in cascaded conferences.
•If the video preview window is opened when the IVR slide is displayed to the
participant, it will also be displayed in the video preview window.
•Video Preview is supported with H.264 High Profile.
•Video Preview is not supported for endpoints using the RTV protocol.
•Video Preview is disabled in encrypted conferences.
•Video preview cannot be displayed when the participant’s video is suspended.
•Participant’s video preview and the CMAD window cannot be open and running
simultaneously on the same PC as both require the same DirectDraw resource.
Workstation Requirements
To be able to display the video preview window, the following minimum requirements
must be met:
•Windows XP, Windows Vista and Windows 7
•Internet Explorer 7 and later
