Conference Profiles

Profiles stored on the MCU enable you to define all types of conferences. Profiles include conference parameters such as Bit Rate, Video Layout, Encryption, etc.

The maximum of Conference Profiles can that be defined is:

• RMX 1500 - 40

• RMX 2000 - 40

• RMX 4000 - 80

Conference Profiles are 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 8, “Conference Templates” .

The RMX is shipped with a default Conference Profile which allows users to immediately start standard ongoing conferences.

Its settings are as follows

Conferencing Modes

Standard Conferencing

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 standard conferencing. Standard conferencing enable several participants to be viewed simultaneously and each connected endpoint uses its highest video, audio and data capabilities up to the maximum bit rate set for the conference.

The main parameters that define the quality of a video conference are:

• Bit Rate - The transfer rate of video and audio streams. The higher

the 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 RMX 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 RMX will send 4CIF (H.263) at 15fps

instead of CIF (H.264) at 30fps.

— H.264 protocol provides better compression of video images in

bit rates lower than 384 Kbps and it will be automatically

selected for the endpoint if it supports H.264.

— When working with RMXs at low bit rates (128, 256, or 384Kbps),

HDX endpoints will transmit SD15 resolution instead of 2CIF

resolution.

When using 1x1 conference layout, the RMX 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.

capabilities to the RMX 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. Operator assistance is available in both MPM, MPM+ and MPMx Card Configuration Modes. For more information, see Chapter 7, “Operator Assistance & Participant Move” on page 7-1.

— 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 are not H.264 enabled. 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 video algorithm. It enables HD compliant endpoints to connect to Continuous Presence conferences at resolutions of 720X576 pixels for PAL systems and 720X480 pixels for NTSC systems. Bit rates for SD range from 256Kbps to 2Mbps. For more information, see "Video Resolutions in CP” on page 2-4.

— High Definition (HD) – HD is an ultra-high quality video

resolution. Depending on the RMX’s Card Configuration mode, compliant endpoints are able to connect to conferences at resolutions ranging from 720p (1280 x 720 pixels) to 1080p (1920 x 1080 pixels) (in MPM+ and MPMx Modes) at bit rates ranging from 1024 Kbps to 4 Mbps (6 Mbps with MPMx). For more information, see "Video Resolutions in CP” on page 2-4.

Polycom RMX 1500/2000/4000 Administrator’s Guide

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 "H.239 / People+Content” on page 2-27.

• 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 2-86.

• Presentation Mode – 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.

• Telepresence Mode - enables the connection of numerous high

definition telepresence rooms and of different models (such as TPX and RPX) into one conference maintaining the telepresence experience. This mode is enabled by a special license.

• Encryption – Used to enhance media security at conference and

participant levels. For more information, see "Message Overlay” on page 2-50.

• Conference Recording - The RMX enables audio and video recording

of conferences using Polycom RSS 2000 recording system.

Additional Conferencing Information

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.

The RMX 1500 contains only an MPMx card.

The RMX 2000 can function with three types of video Media Processing Modules (MPM): MPM, MPM+ and MPMx. These cards differ in their port capacity and their support of video resolutions.

The RMX 4000 can contain MPM+ or MPMx cards.

MPM+ and MPMx cards support additional video resolutions and video quality enhancement such as Video Clarity™ in addition to all video modes and features supported by MPM cards.

Video Session Modes

The RMX offers two video session modes: Continuous Presence and Video Switching. The video session type determines the video display options (full screen or split screen with all participants viewed simultaneously) and the method in which the video is processed by the MCU (with or without using the MCU’s video resources).

Dynamic Continuous Presence (CP) Mode

The Continuous Presence mode offers 35 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.

For conferences with more participants than display squares, the RMX 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.

2-3

Chapter 2-Additional Conferencing Information

Continuous Presence (CP) Conferencing

Video quality in Continuous Presence mode 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.

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 the endpoint according to its capabilities.

The following Video protocols are supported:

• H.261 - the 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.

• H.264 - 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 bit rates.

Video Resolutions in CP

The RMX always attempts to connect to endpoints at the highest line rate. If the connection cannot be established, the RMX attempts to connect at the next highest line rate at its highest supported resolution.

Depending on the line rate, the RMX 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 Quality settings:

• Motion, when selected, results lower video resolution.

• Sharpness, when selected, sends higher video resolution.

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

2-4

Polycom RMX 1500/2000/4000 Administrator’s Guide

Video Resource Usage

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

Default Minimum Threshold Line Rates

The following Table summarizes the Default Minimum Threshold Line Rates and Video Resource usage for each of the pre-defined optimization settings for each Resolution, H.264 Profile, Video Quality setting (Sharpness and Motion) for MPM, MPM+ and MPMx Card Configuration Modes.

2-5

Chapter 2-Additional Conferencing Information

Additional Video Resolutions in MPM+/MPMx Card Configuration Mode

The following higher video quality resolutions are available when the RMX is working in MPM+ or MPMx Mode:

• 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 (symmetric with MPMx).

• HD 1080p 1920 x 1080 pixels at 30 fps (symmetric with MPMx).

The video resolution transmitted to any endpoint is determined by the endpoint’s capabilities, the conference line rate, the Conference Profile’s

Motion and Sharpness settings and the RMX’s Card Configuration Mode (MPM, MPM+ or MPMx).

Additional Intermediate Video Resolutions

2-6

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.

The frame rates (depending on the endpoint’s capability) for both intermediate resolutions are:

•In MPM Mode – 25 or 30 fps.

•In MPM+ / MPMx Mode – 50 or 60 fps.

Polycom RMX 1500/2000/4000 Administrator’s Guide

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.

— 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

RMX transmits HD and receives SD or lower resolutions.

• In panoramic Video Layouts:

— SD: Participants that send CIF also receive CIF. — HD: the RMX transmits HD and receives SD or lower

resolutions, the RMX scales images from SD to HD resolution.

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 Resolution pane of the Resolution Configuration dialog box.

2-7

Chapter 2-Additional Conferencing Information

Depending on the type of Media card(s) installed, the Maximum CP Resolution of the RMX can be set to one of the following resolutions:

Resolution Configuration

All the above 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 Resolution Configuration dialog box enables the RMX administrator to override the default video resolution decision matrix, effectively creating his/her 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 2-5 and "Default Minimum Threshold Line Rates” on page 2-5.

Guidelines

• Resolution Slider settings affect all Continuous Presence (CP) conferences running on the RMX. 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 RMX.

• The displayed sliders and the resolutions change according the Card Configuration Mode: MPM, MPM+ or MPMx.

Chapter 2-Additional Conferencing Information

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. This is the only available resolution configuration in version 6.0.x and earlier.

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 CMA.

The Balanced settings are described in the section: "Continuous Presence (CP) Conferencing” on page 2-4.

• 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.

2-16

Use this option when the priority is 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.

Use this option when the priority is to use higher video resolutions while decreasing the number of participant connections.

• Manual

The administrator adjusts the sliders to accommodate local conferencing requirements.

Polycom RMX 1500/2000/4000 Administrator’s Guide

Sharpness / Motion Resolution Slider Panes

Sharpness and Motion are Video Quality settings that are selected per conference and are defined in the conference Profile and they determine the resolution matrix that will be applied globally to all conferences according to the selection of Sharpness or Motion. The resolution matrix for Sharpness or Motion is determined by the resolution configuration and can be viewed in the Resolution Configuration sliders.

System Resource usage is affected by the Resolution Configuration settings.

Example

As shown in following diagram:

•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

1.5 system resources instead of 3 system resources.

•Moving the HD1080p30 resolution slider from 4096kbps 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 720p30 resolution will instead connect at HD 1080p30 resolution. Each of the affected endpoints will connect at higher resolution but will use 6 system resources instead of 3 system resources.

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 RMX uses two decision matrices (Base Profile, High Profile) to enable endpoints to connect according to their capabilities.

The Detailed Configuration dialog box allows the administrator 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.

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

Chapter 2-Additional Conferencing Information

Video Switching

In Video Switching mode all participants see the same video picture (full screen). The current speaker is displayed in full screen on all the participants' endpoints, while the speaker sees the previous speaker. Switching between participants is voice-activated; whenever a participant starts to speak, he or she becomes the conference speaker and is viewed on all screens. All conference participants must use the same line rate and video parameters such as video protocol, frame rate, annexes and interlaced video mode as no video processing is performed. Compliant endpoints can connect to conferences at the following resolutions:

• H.264 1080p30

• H.264 720p30

• H.264 720p60

• H.264 SD 30

Video Switching uses less system resources than CP: only one CIF video resource per participant for HD resolution. Table 3 lists the resources available to VSW conferences by line rate and card type.

Guidelines

• The display aspect ratio is 4x3 or 16x9.

• Site names, skins, etc. are not supported in Video Switching.

• Video forcing is enabled at the conference and participant levels.

• Endpoints that do not support HD or are unable to meet these

requirements connect as Secondary (audio only).

Enabling Video Switching

For the MCU to run Video Switching conferences the following criteria must be met:

•The HD_THRESHOLD_BITRATE flag must be set in the System

Configuration. The value of this flag is the system minimum threshold bit rate.

The HD_THRESHOLD_BIT RATE flag is responsible for negotiation only, It does not guarantee that the endpoint will open an HD channel or transmit on an opened HD channel.

• The line rate selected in the conference Profile must be the same as or

higher than that specified by the HD_THRESHOLD_BITRATE flag.

•The Video Switching option must be selected in the profile. For more

information see "Defining Profiles” on page 1-9.

• The RMX must have available resources (ports).

• The endpoints must support HD.

H.239 / People+Content

H.239

The H.239 protocol allows compliant endpoints to transmit and receive two simultaneous video streams:

• People Conference – Continuous Presence or Video Switched

conference

• Content Conference – Video Switching conference for content

sharing

By default, all conferences, Entry Queues, and Meeting Rooms launched on the RMX/RMX 4000 have H.239 capabilities.

To view Content, endpoints must use the same Bit Rate, Protocol, and Resolution. An endpoint 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 and MIH cascading topologies. For more details, see "Cascading Conferences - H.239-enabled MIH Topology” on page 2-118.

Polycom RMX 1500/2000/4000 Administrator’s Guide

People+Content

People+Content utilizes a different signaling protocol and is Polycom’s proprietary equivalent of H.239.

H.239 is selected as the preferred communications protocol.

2-27

Chapter 2-Additional Conferencing Information

• People+Content is enabled by default. It can be disabled for all conferences and endpoints by manually adding the flag ENABLE_EPC and changing its value to NO (default setting is YES).

• Endpoints that support People+Content may require a different signaling (for example, FX endpoints). For these endpoints, manually add the flag CS_ENABLE_EPC with the value YES (default value is NO) to the CS_MODULE_PARAMETERS tab.

Content Transmission Modes

The Content channel can transmit one of the following modes:

• Graphics – default mode, for standard graphics

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

• Live Video – highest bit rate, for video clips or live video display

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 RMX can decrease the allocated Content bit rate during a conference.

The following table shows the bit rate allocated to the Content channel from the video channel in each of the three Content modes:

When the flag is set to NO, the RMX only verifies that the endpoint supports the content protocols: Up to H.264 or H.263.

When set to YES, the RMX 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. The flag’s default value is NO.

Chapter 2-Additional Conferencing Information

If the System Flag, does not exist in the system, it must be created using the RMX Menu – Setup option. For more information see the RMX 1500/2000/4000 Administrator’s Guide, "Modifying System Flags” on page 18-5.

Entry Queues

• The selection of either H.263 or Up to H.264 in the Entry Queue Profile does not affect how Content is shared.

• When the endpoint is moved to the conference from the Entry Queue, the endpoint shares Content according to the guidelines set out under Endpoint Capabilities and according to the content protocol that is defined for the target conference.

Cascade Links

Content is shared across a Cascaded Link using H.263 irrespective of whether either or both the cascade-enabled Entry Queue and the Cascaded Link have Up to H.264 Content sharing defined in their profiles.

Content sharing is not supported across an ISDN Cascaded Link between two conferences.

Sending Content to Legacy Endpoints

The RMX can be configured to send Content to H.323/SIP/ISDN endpoints that do not support H.239 Content (legacy endpoints) over the video

(people) channel, allowing the participants using legacy endpoints to view Content instead of the other conference participants.

Guidelines for Sending Content to Legacy Endpoints

• This option is enabled in MPM+ and MPMx Card Configuration Modes only.

• This option is valid when sending Content as a separate stream is enabled in the System Configuration and the flag: ENABLE_H239 is set to YES.

• Additional video resources are allocated to the conference when Content is sent to legacy endpoints:

— In MPM+ mode, an additional SD video resource is allocated. — In MPMx mode, an additional HD video resource is allocated.

The allocation is done only when a legacy endpoint is connected to the conference and a Content session is initiated and transmitted via the video channel.

2-32

Polycom RMX 1500/2000/4000 Administrator’s Guide

Once the resource is allocated, it remains allocated to the conference until the conference ends. If the system cannot allocate the resource required for sending the Content, the conference status changes to “Content Resource Deficiency” and Content will not be sent to the legacy endpoints.

As the resource required for sending Content to legacy endpoints is allocated on the fly, when scheduling a reservation, in rare occasions when the MCU is fully loaded, “Resource deficiency” may be encountered. This may prevent participants from connecting to the conference or from Content being sent to the legacy endpoint. To ensure resource for sending Content to legacy endpoints, add one resource to the number of resources defined in the Reserve Resources for Video Participants field, in the Conference Properties - General dialog box.

• Non-H.239 (legacy) endpoints receive the Content via the video

channel using the same video protocol and resolution with which they receive video.

• The highest Content resolution is HD720p, even if HD1080p is

selected in the Profile.

• Content cannot be sent to legacy endpoints when Same Layout mode

is selected for the conference.

• This option in not supported in High Definition Video Switching

conferences.

• When Content is transmitted, the Site Name of the endpoints cannot

be viewed.

• Content can be sent to legacy endpoints in gateway calls.

• When moving a legacy participant to the Operator conference, Content

will not be available to the legacy endpoint.

Interoperability with Polycom CMA and DMA

The CMA uses the Profiles that are stored in the RMX. If the Send Content to Legacy Endpoints option is enabled in the Conference Profile, this option

will be enabled in the conference started from the CMA that uses that Profile. However, the CMA does not display an indication that this option is enabled for the conference.

2-33

Chapter 2-Additional Conferencing Information

A new conference can be started on the DMA using a Conference Profile that is defined on the RMX or by defining all the conference parameters. The Send Content to Legacy Endpoints option can be enabled only in the Conference Profile defined in the RMX, therefore, to include this option in the conference started on the DMA use an RMX existing Profile. However, the DMA does not display an indication that this option is enabled for the conference.

Content Display on Legacy Endpoints

When Contents is sent to legacy endpoints, their video layout automatically changes to a “Content layout” which is defined by the system flag LEGACY_EP_CONTENT_DEFAULT_LAYOUT and the Content is shown in the larger/top left (“speaker”) window. The video layouts of the other conference participants do not change.

The switch to the Content layout occurs in the Auto Layout, Presentation Mode, Lecture Mode and when a layout is selected for the conference. However, in Lecture Mode, when Content is sent to legacy endpoints, when switching to the Content layout, the Content is shown in the “lecturer/speaker” window and the lecturer is show in a second window. If the layout contains more than two windows, all other windows will be empty. All other participants will see the lecturer in full screen.

In Same Layout mode, Content cannot be sent to legacy endpoints.

The LEGACY_EP_CONTENT_DEFAULT_LAYOUT Flag default is set to a layout of 1+4 where the Content is shown in the large window and the other conference participants are shown in the small windows. This default value can be changed in the System Configuration.

When Content is stopped, the layout of the legacy participants returns to the last video layout seen prior to the Content mode.

The Legacy participants can change their layout using Click&View. In such a case, the Content is forced to the “speaker” window.

The RMX user can also change the layout for the participants the legacy endpoints (selecting personal layout).

When forcing a video participant to the Content window (instead of Content), the Content display can be restored only by selecting any other video layout.

Video Preview

RMX 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 RMX 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 RMX 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 RMX user.

Video Preview Guidelines

• Video preview is available in Continuos Presence and Video Switching

conferences.

• 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.
