Conference Profiles
Profiles stored on the MCU enable you to define all types of conferences. Profiles include
conference parameters such as Conference Line Rate, People and Content resolution and
settings, Video Layout, Encryption, Lost Packet Recovery, etc.
The maximum number of Conference Profiles that can be defined is 40.
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. Profile changes are not implemented in or affect ongoing
conferences.
Conference Profile options differ according to the selected Conference Type. AVC (Advanced
Video Codec) Conferencing Mode offers Continuous Presence (CP) conferences and a
special functional conference - Operator Conferences.
Conferences based on 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, “Conference Templates” .

Conferencing Mode
The MCU system offers Transcoding - AVC 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.261, H.263, H.264 Base and High profile
•Video Resolutions: from QCIF, CIF and up to 1080p
•Frame rates up to 60 fps
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 - Continuous Presence (CP) Conferencing” on page 2-2.
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.
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), 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 Quality – Motion or Sharpness
•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 the 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.
Polycom, Inc.2-3
Polycom® RMX™ 1800 Administrator’s Guide
•H.263 - a video compression algorithm that provides a better video quality than H.261.
This standard is not supported by all endpoints.
•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.
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.
— 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
2-4Polycom, Inc.
Chapter 2-Conference Profiles
connect to Continuous Presence conferences at resolutions of 720X576 pixels for
PAL systems and 720X480 pixels for NTSC systems. For more information, see
"Video Resolutions in AVC-based CP Conferencing” on page 3-1.
— High Definition (HD) – HD is an ultra-high quality video resolution that uses he
H.264 and H.264 High Profile video algorithms. Endpoints are able to connect to
conferences at the following resolutions:
•720p (1280 x 720 pixels)
•1080p (1920 x 1080 pixels)
For more information, see "Video Resolutions in AVC-based CP Conferencing” on
page 3-1.
Supplemental Conferencing Features
In addition to Standard Conferencing the following features can be enabled:
•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 4-1.
•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” on page 4-38.
•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 "Media Encryption” on page 4-27.
•Conference Recording - The Collaboration Server enables audio and video recording of
conferences using Polycom RSS recording system.
Operator Conferences (CP only Conferences)
Offers additional conference management capabilities to the Collaboration Server users,
enabling them to attend to participants with special requirements and acquire participant
details for billing and statistics. This service is designed usually for large conferences that
require the personal touch. For more information, see Chapter 10, “Operator Assistance & Participant Move” on page 10-1
