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.

Polycom, Inc. 2-1

Polycom® RMX™ 1800 Administrator’s Guide

AVC Conferencing - Continuous Presence (CP) Conferencing

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.

2-2 Polycom, Inc.

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

2-4 Polycom, 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

Field/Option Description

Chapter 2-Conference Profiles

Mute participant except lecturer

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.

• In cascaded conferences, all participants (including the link

participants) are muted. Only the lecturer is not muted.

Video Protocols and Resolution Configuration for CP Conferencing

Video Resolutions in AVC-based CP Conferencing

The following video resolution information applies to AVC CP Conferencing Mode.

The Polycom RMX 1800 always attempts to connect to endpoints at the highest line rate defined for the conference. If the connection cannot be established using the conference line rate, the Collaboration Server attempts to connect at the next highest line rate at its highest supported resolution.

Depending on the line rate, the Collaboration Server sends video at the best possible resolution supported by the endpoint regardless of the resolution received from the endpoint.

The video resolution is also defined by the Video Quality settings in the Profile.

• Motion, when selected, results in lower video resolution at higher frame rates (30 fps to

60 fps).

• Sharpness, when selected, results in higher video resolution at lower frame rate (30 fps

and lower). However, it can also be sent in 1080P 60fps.

The combination of frame rate and resolution affects the number of video resources required on the MCU to support the call.

The following resolutions are supported:

• CIF 352 x 288 pixels at 30 or 60 fps.

• SD 720 x 576 pixels at 30 or 60 fps.

• HD 720p 1280 x 720 pixels at 30 or 60 fps.

• HD 1080p 1920 x 1080 pixels at 30 fps

• HD 1080p 1920 x 1080 pixels at 60 fps (Symmetric in Motion and Sharpness)

Video Display with CIF, SD and HD Video Connections

Although any combination of CIF, SD and HD connections is supported in all CP conferences, the following rules apply:

• In a 1X1 Video Layout:

— SD: If the speaker transmits CIF, the MCU will send CIF to all participants,

including the SD participants. In any other layout the MCU will transmit to each participant at the participant’s sending resolution.

Polycom, Inc. 3-1

Polycom® RMX 1800 Administrator’s Guide

— HD: The MCU transmits speaker resolution (including input from HD

participants) at up to SD resolution. If 1x1 is the requested layout for the entire duration of the conference, set the conference to HD Video Switching mode.

• In asymmetrical Video Layouts:

— SD: A participant in the large frame that sends CIF is displayed in CIF.

— HD: Where participants’ video windows are different sizes, the Collaboration Server

transmits HD and receives SD or lower resolutions.

• In panoramic Video Layouts:

— SD: Participants that send CIF also receive CIF. — HD: the Collaboration Server transmits HD and receives SD or lower resolutions,

the Collaboration Server scales images from SD to HD resolution.

H.264 High Profile Support in CP Conferences

The H.264 High Profile is a new addition to the H.264 video protocol suite. It uses the most efficient video data compression algorithms to even further reduce bandwidth requirements for video data streams.

Video quality is maintained at bit rates that are up to 50% lower than previously required. For example, a 512Kbps call will have the video quality of a 1Mbps HD call while a 1Mbps HD call has higher video quality at the same (1Mbps) bit rate.

H.264 High-Profile should be used when all or most endpoints support it.

Guidelines

• H.264 High Profile is supported in H.323, and SIP networking environments.

• H.264 High Profile is supported in Continuous Presence conferences at all bit rates, video resolutions and layouts.

• H.264 High Profile is the first protocol declared by the Collaboration Server, to ensure that endpoints that support the protocol will connect using it.

Setting minimum bit rate thresholds that are lower than the default may affect the video quality of endpoints that do not support the H.264 High Profile.

• For monitoring purposes, the Collaboration Server and endpoint H.264 High Profile capability is listed in the Participant Properties - H.245 and SDP tabs for H.323 participants and SIP participants respectively. For more information see "IP Participant Properties” on page 12-15.

• H.264 High Profile is not supported:

— For Content Sharing — With Video Preview

• HD1080p 60 is supported in Continuous Presence (CP) mode:

— In Motion Video Quality mode — With maximum bit rate of up to 4 Mbps — With a-symmetrical video qualities, the RMX receives HD720p60 and sends

HD1080p60.

• PAL endpoints are supported at a frame rate of 50 fps.

•Each HD1080p60 participant consumes 4 HD video resources.

3-2 Polycom, Inc.

• HD1080p60 is not supported:

— With Content sharing.

CP Conferencing with H.263 4CIF

The video resolution of 4CIF in H.263 endpoints is only supported for conferences in which the video quality is set to sharpness and for line rates of 384 Kbps to 1920 Kbps as shown in the following table.

Table 3-1 Video Quality vs. Line Rate

The Collaboration Server Web Client supports monitoring of H.263 4CIF information. The H.245 or SDP tab includes the additional information.

The creation of a new H.263 4CIF slide is supported in the IVR Service in addition to the current H.263 IVR slide. If users utilize the default Polycom slides that are delivered with the Collaboration Server, the slide’s resolution will be as defined in the profile, i.e. SD, HD, CIF, etc.

For more information see “High Resolution Slides” on page 15-13.

Resolution Frame Rate Resolution Frame Rate

H.263 4CIF Guidelines

• H.263 4CIF is supported with H.323 and SIP connection endpoints.

• H.263 4CIF is supported in CP mode only.

• AES encryption is supported with H.263 4CIF.

• Recording of H.263 4CIF conferences is supported by the RSS 4000 and other devices.

• All video layouts are supported in H.263 4CIF, except 1x1 layout. In a 1x1 layout, the resolution will be CIF.

• H.239 is supported in H.263 4CIF and is based on the same bandwidth decision matrix as for HD.

The CP Resolution Decision Matrix

All the CP resolution options and settings are based on a decision matrix which matches video resolutions to connection line rates, with the aim of providing the best balance between resource usage and video quality at any given line rate.

The following factors affect the decision matrices:

• The used video protocol: H.264 base Profile or H.264 High Profile. The H.264 High Profile maintains the Video quality at bit rates that are up to 50% lower than previously

Polycom, Inc. 3-3

Polycom® RMX 1800 Administrator’s Guide

required. For example, a 512 kbps call will have the video quality of a 1Mbps HD call while a 1Mbps HD call has higher video quality at the same (1Mbps) bit rate.

• A different decision matrix is used for Motion and Sharpness as the quality requirements are different.

By default, the system shipped with three pre-defined settings of the decision matrix for H.264 Base Profile and three pre-defined settings of the decision matrix for H.264 High Profile with Motion and Sharpness video quality for each:

• Resource-Quality Balanced (default)

A balance between video quality and resource usage. This is the only available resolution configuration in version 6.0.x and earlier.

• Resource Optimized

System resource usage is optimized by allowing high resolution connections only at high line rates and may result in lower video resolutions (in comparison to other resolution configurations) for some line rates. This option allows to save MCU resources and increase the number of participant connections.

• Video Quality Optimized

Video is optimized through higher resolution connections at lower line rates increasing the resource usage at lower line rates. This may decrease the number of participant connections.

Video Resource Usage

Video resource usage is dependent on the participant’s line rate, resolution and Video Quality settings.

H.264 Base Profile and High Profile Comparison

The following illustrations show a comparison between the resolutions used at various line rates for H.264 baseline and the H.264 High Profile, for Motion and Sharpness Video Quality setting according to the Resolution Configuration Mode (Balanced, Resource Optimized or Video Quality Optimized).

Resolution Configuration for CP Conferences

The Resolution Configuration dialog box enables you to override the default video resolution decision matrix, effectively creating your own decision matrix. The minimum threshold line rates at which endpoints are connected at the various video resolutions can be optimized by adjusting the resolution sliders.

System resource usage is also affected by the Resolution Configuration settings. For more information see "Video Resource Usage” on page 3-4 and "Default Minimum Threshold Line Rates and Resource Usage Summary” on page 3-9.

Guidelines

• Resolution Slider settings affect all Continuous Presence (CP) conferences running on the Collaboration Server. Video Switched conferences are not affected.

• A system restart is not needed after changing the Resolution Slider settings.

• Resolution Slider settings cannot be changed if there are ongoing conferences running on the Collaboration Server. .

be used as the basis for manual fine tuning of resolution settings by the administrator.

The Manual radio button is automatically selected if any changes are made to the Resolution Sliders.

The Resolution Configurations are:

• Resource-Quality Balanced (default)

A balance between the optimized video quality and optimized resource usage.

Use this option:

• When the priority is to maintain a balance between resource usage and video quality.

• When it is necessary to maintain backward compatibility with previous versions.

• When working with Polycom DMA/RealPresence Resource Manager.

The Balanced settings are described in the section: "Default Minimum Threshold Line Rates and Resource Usage Summary” on page 3-9.

• Resource Optimized

System resource usage is optimized by allowing high resolution connections only at high line rates and may result in lower video resolutions (in comparison to other

resolution configurations) for some line rates.

Use this option when the priority is to save MCU resources and increase the number of participant connections.

Resolution Configuration - Detailed

H.264 High Profile allows higher quality video to be transmitted at lower bit rates.

However, setting minimum bit rate thresholds that are lower than the default may affect the video quality of endpoints that do not support the H.264 High Profile. The Collaboration Server uses two decision matrices (Base Profile, High Profile) to enable endpoints to connect according to their capabilities.

Sharpness and Motion

Sharpness and Motion are Video Quality settings that are selected per conference and are defined in the conference Profile. A conference with Sharpness selected in its Profile uses the

Sharpness settings of the Resolution Configuration and a conference with Motion selected in its Profile uses the Motion settings of the Resolution Configuration dialog box.

The Sharpness and Motion tabs in the Resolution Configuration dialog box allow you to view and modify Resolution Configuration settings for conferences with either Video Quality setting.

Resolution Configuration Sliders

The Detailed Configuration dialog box allows you to configure minimum connection threshold bit rates for endpoints that support H.264 High Profile and those that do not support H.264 High Profile by using the following slider panes:

• Base Profile - Endpoints that do not support H.264 High Profile connect at these minimum threshold bit rates.

Polycom, Inc. 3-13

Polycom® RMX 1800 Administrator’s Guide

• High Profile - Endpoints that support H.264 High Profile connect at these minimum threshold bit rates.

Although the default minimum threshold bit rates provide acceptable video quality, the use of higher bit rates usually results in better video quality but will require more resources.

The Base Profile and High Profile sliders operate in the same manner in Sharpness and in

Motion.

Video Resource usage is affected by the Resolution Configuration settings. The lower the line

rate threshold set for a certain resolution the more resources will be used to connect that participant (as a higher resolution will be used).

Moving the slider of a certain resolution to the left reduces the line rate threshold required for the endpoints to connect using that resolution (resulting in higher video quality, more video resources). Moving the slider to the right, increases the line rate required for the endpoint to connect using that resolution (resulting in lower video quality, less video resources).

The following example demonstrate the usage of the sliders.

•Moving the HD720p30 resolution slider from 1024kbps to 1920kbps increases the minimum connection threshold line rate for that resolution. Endpoints connecting at line rates between 1024kbps and 1920kbps that would have connected at HD 720p30 resolution will instead connect at SD 30 resolution. Each of the affected endpoints will connect at lower resolution but will use less video resources.

•Moving the HD1080p60 resolution slider from 3584kbps to 2560kbps decreases the minimum connection threshold line rate for that resolution. Endpoints connecting at line rates between 2560kbps and 4096kbps that would have connected at HD 1080p30 resolution will instead connect at HD 1080p60 resolution. Each of the affected endpoints will connect at higher resolution but will use more video resources.

Flag Settings

Setting the Maximum CP Resolution for Conferencing

The MAX_CP_RESOLUTION flag value is applied to the system during First-time Power-up and after a system upgrade. The default value is HD1080.

All subsequent changes to the Maximum CP Resolution of the system are made by selections in the Max CP Resolution pane of the Resolution Configuration dialog box.

Minimum Frame Rate Threshold for SD Resolution

The MINIMUM_FRAME_RATE_THRESHOLD_FOR_SD System Flag can be added and set to prevent low quality, low frame rate video from being sent to endpoints by ensuring that an SD channel is not opened at frame rates below the specified value. For more information see "Modifying System Flags” on page 20-1.

Additional Video Resolutions

The following higher video quality resolutions are available with the Collaboration Server

• CIF 352 x 288 pixels at 50 fps.

• WCIF 512 x 288 pixels at 50 fps.

• WSD 848 x 480 pixels at 50 fps.

• W4CIF 1024 x 576 pixels at 30 fps.

• HD 720p 1280 x 720 pixels at 60 fps.

• HD 1080p 1920 x 1080 pixels at 30 fps.

• HD 1080p 1920 x 1080 pixels at 60 fps.

Two higher quality, intermediate video resolutions replace the transmission of CIF (352 x 288 pixels) or SIF (352 x 240 pixels) resolutions to endpoints that have capabilities between:

• CIF (352 x 288 pixels) and 4CIF (704 x 576 pixels) – the resolution transmitted to these endpoints is 432 x 336 pixels.

• SIF (352 x 240 pixels) and 4SIF (704 x 480 pixels) – the resolution transmitted to these endpoints is 480 x 352 pixels.

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

• 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 .

Polycom, Inc. 4-1

Polycom® RMX 1800 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

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 addressing modes.

• BFCP utilizes an unsecured channel (port 60002/TCP) even when SIP TLS is enabled. 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 BFCP capabilities to Polycom and Avaya endpoints.

•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 20-1.

• 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.

The Collaboration Server’ s Content sharing determined by the System Flag’s settings and SIP Client capabilities are summarized in Table 4-1.

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

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.

In Multiple Content Resolutions mode, content is shared in multiple streams, one for each video protocol: H.263 and H.264. A separate video resource is used to process the Content shared with H.264-capable endpoints and another for content shared with H.263-capable endpoints, with each endpoint receiving its highest possible quality. This allows endpoints with different protocols to connect and disconnect without having to restart Content sharing in the middle of a conference.

In this mode, endpoints that do not support the content capabilities set for the conference will receive the content over the video (people) channel (“Legacy” content).

Content parameters are defined in the Conference Profiles - Video Quality dialog box.

Content Sharing Parameters in Content Highest Common (Content Video Switching) Mode

This section describes the possible content sharing parameters when content Highest Common mode is used:

• Content Settings

• Content Protocol

Polycom, Inc. 4-5

Polycom® RMX 1800 Administrator’s Guide

• Content Resolution

Content Settings

The Content channel can transmit one of the following modes:

• Graphics – for standard graphics.

• Hi-res Graphics – requiring a higher bit rate, for high quality display or highly

detailed graphics.

• Live Video

• Customized Content Rate

Rate.

Content Setting

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:

– highest bit rate, for video clips or live video display.

Content Protocols

Two Content Protocols can be used for sharing content:

• H.263

• H.264

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

• H.264 Cascade and SVC Optimized

H.263 & H.264 Auto Selection ()

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.

Polycom, Inc. 4-7

Polycom® RMX 1800 Administrator’s Guide

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.

H.263

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 4-5.

H.264 HD default

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 4-9.

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 4-5.

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.

• The minimum Content Rate required for allowing a participant to share Content is the lower valued parameter when comparing the System Flag setting (Table 4-6) and the content bit rate allocation derived from the conference line rate.

When the flag settings enable an endpoint to share Content at a content rate that is lower than the conference content rate, the content rate of the entire conference is reduced to the content rate supported by that endpoint.

4-8 Polycom, Inc.

Chapter 4-Additional Conferencing Information

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

In order to change the System Flag values, the flags must be manually added to the System Configuration. For more information see "Modifying System Flags” on page 20-1.

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.

In AVC CP conferences, each content Line Rate and Content Setting has its own resolution and frame rate.

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.

• H.264 High Profile is not supported.

4-10 Polycom, Inc.

Chapter 4-Additional Conferencing Information

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.

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 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.

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.

4-12 Polycom, Inc.

Chapter 4-Additional Conferencing Information

•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

Customized Content Rate functionality can be implemented when a Conference Content 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. 4-13

Polycom® RMX 1800 Administrator’s Guide

To Select the Customized Content Rate:

Customized Content Rate is enabled in the Profile - Video Quality dialog box.

1 In 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.

2 Select 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 Conference Line Rate is too low to support the selected Content Line Rate. Click Cancel and reconfigure either of the Line Rates or click OK to return to the default Content Setting.”

You can then modify either the Content Line Rate or the Conference Line Rate or select another Content Setting option.

Exclusive Content Mode

Exclusive Content Mode allows you to limit Content broadcasting to one participant, preventing other participants from interrupting the Content broadcasting while it is active.

4-16 Polycom, Inc.

Chapter 4-Additional Conferencing Information

Guidelines

•The Exclusive Content Mode is enabled or disabled by a check box in the in the Advanced tabs of the Conference Profile. The check box is cleared (feature is disabled) by default.

• Exclusive Content Mode can be enabled or disabled during an ongoing conference using the Conference Properties - Advanced dialog box.

•In Exclusive Content Mode, if the RESTRICT_CONTENT_BROADCAST _ TO_LECTURER System Flag is set to:

Polycom, Inc. 4-17

Polycom® RMX 1800 Administrator’s Guide

— NO - the first participant to send content becomes the Content Token holder and has

to release the Content Token before any other participant can acquire the token and begin transmitting Content.

— YES - only the designated Lecturer can be the Content Token holder.

•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: >> In the Conferences list pane, right-click the conference icon and then click Abort H.239

Session.

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.

4-18 Polycom, Inc.

Chapter 4-Additional Conferencing Information

• In cascaded conferences, a participant functioning as the cascade link cannot be given token ownership.

Giving and Cancelling Token Ownership

To give token ownership:

1 In the Participants list, right click the AVC-enabled endpoint that is to receive Content

Token ownership.

2 Select 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.

Polycom, Inc. 4-19

Polycom® RMX 1800 Administrator’s Guide

To cancel token ownership:

1 In the Participants list, right click the endpoint that currently has Content Token

ownership.

2 Select 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

• MAX_INTRA_SUPPRESSION_DURATION_IN_SECONDS_CONTENT

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.

4-20 Polycom, Inc.

Chapter 4-Additional Conferencing Information

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

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.

Content Sharing via the Polycom CCS Plug-in for Microsoft Lync Clients

From version 8.1, Polycom CCS (Content Collaboration Solution) Plug-in for Lync clients allows Lync clients to receive and send Content on a separate channel, without having to use the video channel. Content is transmitted using SIP BFCP.

For more information, see Appendix 4, “Exclusive Content Mode”on page 4-16.

Video Preview

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 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.

• Only one preview window can be displayed for each Collaboration Server Web Client connection (workstation).

Polycom, Inc. 4-21

Polycom® RMX 1800 Administrator’s Guide

• Only one preview window can be displayed for a single conference and up to four preview windows can be displayed for each 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 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.
