5 SVC Conferencing Solution Overview This chapter describes the Polycom RealPresence SVC Conferencing solution, a general description of SVC, and using the SVC conferencing solution. This chapter includes the following topics: SVC Conferencing Overview Using the Polycom RealPresence SVC-Based Conferencing Solution SVC Conferencing Overview This section provides a general description of the SVC protocol and video conferencing using the SVC protocol. Overview of SVC Scalable Video Coding (SVC), an extension of the H.264/MPEG4-AVC video protocol, is a powerful video compression protocol that enables the standardization of encoding high-quality video streams to provide scalable adaptation to various application requirements, such as the display and processing capabilities of video devices and varying transmission conditions. SVC provides network-friendly scalability at a bit-stream level, with a moderate increase in encoder and decoder complexity, which is relative to the single layer H.264 AVC protocol. SVC enables high flexibility for implementation and optimization in various application scenarios. It provides a wide range of display and processing capabilities of target devices and varying transmission conditions for video conferencing to serve the various needs of users with different displays and CPUs (video conference endpoints, laptops, tablets, and mobile phones) connected through different network links, such as LAN and wireless. In video conferencing, efficient scalable video coding provides certain benefits in the transmission of video streaming. For example, a video conference with heterogeneous clients where multiple bit streams of the same video content differing in picture size, frame rate, and bit rate should be provided simultaneously. An SVC solution could make use of simulcasting, in which multiple SVC streams are made available to the different clients, allowing each client to select the picture size, frame rate, and bit rate that best suits their needs. This provides a scalable bit stream set from which representations with lower resolution or quality can be obtained. A video client with restricted resources such as display resolution, processing power, or battery power, needs to decode the lowest available bit stream. The following diagram illustrates an example of the various devices and bandwidths that can be used in an SVC-based video conferencing environment: Polycom, Inc. 1

6 Polycom RealPresence SVC-Based Conferencing Solutions Deployment Guide Using the Polycom RealPresence SVC-Based Conferencing Solution This section describes the Polycom RealPresence SVC-Based Conferencing solution and its components. This section includes the following topics: Overview of the RealPresence SVC-Based Conferencing Solution Using SVC-Enabled Endpoints in a Mixed AVC CP and SVC Conference Allocating Available Bandwidth During Calls SVC Encryption Optimizing Video Traffic B2B Support using the RealPresence SVC-Based Conferencing Solution Detecting SVC/SIP Endpoint Disconnections Overview of the RealPresence SVC-Based Conferencing Solution The RealPresence SVC-Based conferencing solution is a powerful and innovative video conferencing mode that provides high-quality video streaming between endpoints with lower resolutions, frame rates, and line rates. SVC conferences also provide up to three high video capacity resolutions, better error resiliency, and lower latency. Using the SVC video protocol, SVC conferences provide video bit streams at different resolutions, frame rates and line rates to SVC-enabled endpoints with various display capabilities and layout configurations. Polycom, Inc. 2

7 Polycom RealPresence SVC-Based Conferencing Solutions Deployment Guide In the SVC-based conference, each SVC-enabled endpoint transmits multiple resolutions and temporal layers to the Polycom RealPresence Collaboration Server (RMX) 1500/1800/2000/4000 or the RealPresence Collaboration Server (RMX) 800s, enabling each endpoint to transmit at different resolutions and frame rates, such as 180p at 7.5fps and 15fps, 360p at 7.5 fps, 15fps and 30fps, 720p at 7.5fps, 15fps, and 30fps. Polycom SVC-enabled endpoints (Polycom RealPresence Desktop, Polycom RealPresence Mobile, and the Polycom RealPresence Group Series 300/500/700) enable video conference layouts to be automatically assembled by the endpoint giving more flexibility to the endpoint. This enables the RealPresence Collaboration Server (RMX) to send or relay the selected video streams to the endpoints without sending the entire video layout to the endpoints. The video streams displayed in the conference layout on each endpoint are obtained from the different streams received from each of the endpoints displayed in the layout. Depending on the size of the video cell in the configured layout, the endpoint requests the video stream in the required resolution from the RMX. The higher the display quality and size, the higher the requested resolution is sent to the endpoint. The endpoint creates the displayed layout from the different video streams it receives. The following diagram illustrates how the RealPresence Collaboration Server (RMX) is used as a media relay server in an SVC-based conference: For instance, an SVC endpoint might want to receive three video streams at different frame rates and resolutions, and create a conference layout with the received video streams. Each SVC-enabled endpoint sends and receives encoded SVC bit streams to and from the RealPresence Collaboration Server (RMX). Polycom, Inc. 3

8 Polycom RealPresence SVC-Based Conferencing Solutions Deployment Guide As another example, the SVC stream sent from a RealPresence Desktop client (1) transmits bit streams suited for both a RealPresence Mobile client (2) and a RealPresence Desktop client (4). The transmitted bit streams might contain a compressed video with a lower bit rate to support the capability of the receiving client. The RealPresence Collaboration Server (RMX) determines which of the incoming bit streams to send to each endpoint. It does not perform any encoding and decoding or any transcoding of the video streams. The RealPresence Collaboration Server (RMX) functions as the multipoint media relay to the endpoints. For voice activated selection of the video streams, the RealPresence Collaboration Server (RMX) determines which of the incoming bit streams to send to each endpoint. SVC video conferences provide a robust bandwidth-efficient technology that deliver a consistently high-quality user experience across networks with varying degrees of quality of service. SVC increases the scalability of video networks and enables mass desktop video deployments. Some of the advantages of SVC conferencing are: Offers high-resolution video conferencing with low end-to-end latency, improved error resiliency and high system capacity. Allows the SVC-enabled video endpoints to manage display layouts, support multiple resolutions and data rates. SVC provides simulcasting at different resolutions with more layout building options on the endpoint. It also provides flexible in-stream selection to accommodate various endpoint capabilities, such as bandwidth, CPU, screen resolution, and so on. Supports video layouts on two display monitors for the RealPresence Group Series endpoints. The RealPresence Collaboration Server (RMX) functions as a media relay server providing low cost production benefits. The RealPresence Collaboration Server (RMX) reduces bandwidth usage by only selecting the necessary video stream to be sent to the endpoints. Using SVC-Enabled Endpoints in a Mixed AVC CP and SVC Conference Three types of conferences are defined in the RealPresence Collaboration Server (RMX): AVC CP Only SVC Only Mixed AVC CP and SVC In an AVC CP Only conference, endpoints that use various protocols such as H.263, H.264 AVC, and RTV can be connected to the conference. All Polycom SVC-enabled endpoints support the H.264 AVC protocol and can connect to an AVC CP Only conference. In an SVC Only conference, only the H.264 SVC protocol is supported. Endpoints that do not support the H.264 SVC protocol cannot connect to an SVC Only conference. However, in a mixed AVC CP and SVC conference, both AVC-capable and SVC-enabled endpoints can be supported in the same conference. The RealPresence Collaboration Server (RMX) 1500/2000/4000, in addition to the RealPresence Collaboration Server (RMX) 800s - Virtual Edition, can manage a mixed AVC CP and SVC conference. In a mixed AVC CP and SVC conference, SVC endpoints transmit multiple resolutions and temporal layers to the RealPresence Collaboration Server (RMX), while AVC endpoints send only one H.264 AVC video stream to the Collaboration Server. Other endpoint types can send different kinds of video streams. The Collaboration Server relays SVC-decoded video streams to the SVC-enabled endpoints in the conference according to their display capabilities. This enables the video conference layouts to be automatically assembled by the endpoint. Polycom, Inc. 4

9 Polycom RealPresence SVC-Based Conferencing Solutions Deployment Guide AVC endpoints connected to the conference send a single H.264 AVC video stream to the Collaboration Server, which is then transcoded to SVC video streams. AVC endpoints receive a single video bit stream with the defined video conference layout from the Collaboration Server. SVC-enabled endpoints receive the AVC converted video bit streams through the Collaboration Server from the AVC endpoints as a single SVC video bit stream. In this mixed AVC CP and SVC conferencing, both SVC and AVC endpoints in the conference receive the same AVC CP layout. The following diagram illustrates an example of a mixed AVC CP and SVC conferencing mode: In this example, an SVC endpoint (1) receives three video streams at different frame rates and resolutions, and creates the conference layout with the received video streams. The video bit stream that the SVC endpoint receives from the AVC endpoint (3) is transcoded in the Collaboration Server and then encoded into an SVC bit stream in the required resolution. Alternatively, an AVC endpoint (4) sends a single resolution video stream to the Collaboration Server. The Collaboration Server first converts the SVC bit stream into AVC, then transcodes the video received from the other endpoints to the required resolution. The Collaboration Server composes the video layout for the AVC endpoint and sends a single resolution video stream with the video layout to the participant. In the displayed example, the Collaboration Server creates different video layouts for each AVC endpoint. In a mixed AVC CP and SVC conference when packet loss occurs, the Collaboration Server uses the Polycom proprietary Lost Packet Recovery (LPR) component to recover lost packets for AVC-capable endpoints and uses the Error Resiliency and the Media Bandwidth Allocation (MBA) components to retransmit lost packets for SVC-enabled endpoints. Polycom, Inc. 5

10 Polycom RealPresence SVC-Based Conferencing Solutions Deployment Guide Video Layouts in the Mixed AVC CP and SVC Conference Mode Video layouts that are used in the mixed AVC CP and SVC conferencing mode depend on the endpoint of the participant. SVC endpoints display the same video layouts whether in an SVC Only conference or in a mixed AVC CP and SVC conference. AVC endpoints display video layouts as configured by the Collaboration Server. The RealPresence Group Series endpoints can use dual monitors to display various video layouts. The video layouts for the RealPresence Group Series endpoints differ from the video layouts displayed in the Polycom SVC applications (RealPresence Desktop and RealPresence Mobile) and AVC endpoints. For a detailed description of the video layouts for the RealPresence Group Series, see Video Layouts for the RealPresence Group Series. Using the Polycom SVC applications and AVC-capable endpoints, the participant who is currently speaking is displayed with a colored border (orange or yellow), depending on the type of skin of the conference, while the participants that are listening are displayed in the other panes. AVC endpoints can use the PiP (Picture in Picture) option, which displays the participant s Self View. This can change the video layouts view. The following table illustrates how participants are displayed in video layouts for both SVC and AVC endpoints: Video Layouts for Mixed AVC CP and SVC Conferences Number of Participants SVC Endpoints (RPD) AVC Endpoints (Auto Layout) Polycom, Inc. 6

11 Polycom RealPresence SVC-Based Conferencing Solutions Deployment Guide Number of Participants SVC Endpoints (RPD) AVC Endpoints (Auto Layout) Polycom, Inc. 7

12 Polycom RealPresence SVC-Based Conferencing Solutions Deployment Guide Number of Participants SVC Endpoints (RPD) AVC Endpoints (Auto Layout) 12 AVC endpoints can support up to 16 participants in a video layout. In the AVC endpoints video layout for 10 participants, the current speaker is displayed in a larger video pane. The other seven smaller panes display the participants who have previously spoken in the conference. The video layout displays the participants in speaker order - the participant who was the speaker before the other participants were displayed is no longer displayed in the video layout. In layout 2+8, the two central windows display the last two speakers in the conference -- the current speaker and the previous speaker. To minimize the changes in the layout, when a new speaker is identified, the previous speaker is replaced by the new speaker, while the current speaker remains in their window. Allocating Available Bandwidth During Calls As SVC-enabled endpoints transmit video streams to the Collaboration Server, the Collaboration Server is used as a relay server sending media streams between other SVC-enabled endpoints. Video conferences deliver media streams as datagrams (packets) across the internet and are subject to possible packet loss. Polycom s AVC video conferencing endpoints can minimize packet loss by using Lost Packet Recovery (LPR). When required, the MCU reduces or increases the bandwidth to avoid network congestion using the Dynamic Bandwidth Allocation (DBA). The DBA dynamically adapts the bandwidth used to the network status. However, SVC-based conferencing is different from the traditional ACV CP conferencing as there is no transcoding of the media streams. Therefore, different error resiliency methods are used. Using Polycom s Media Relay Bandwidth Allocation (MBA) algorithm, designed specifically for SVC-enabled endpoints, media streams are retransmitted when packet loss occurs because of network congestion. Similar to the DBA for AVC conferences, the MBA reduces the effective bandwidth used to avoid network congestion and decrease the packet loss percentage. This provides recovery of lost packets while maintaining and adjusting the bandwidth of the endpoint. Media Relay Bandwidth Allocation is beneficial for both constrained pipes and network congestion using the following methods: Constrained Pipe - Identifies that available bandwidth in each direction is lower than defined in the beginning of the call and is adjusted accordingly. Dynamic Congestion - Measures the effective bandwidth during the call and dynamically modifies the effective bandwidth accordingly. Using these methods to handle packet loss, MBA provides available bandwidth allocation to SVC-enabled endpoints for packet loss recovery with a quick transition to the endpoint. Polycom, Inc. 8

13 Polycom RealPresence SVC-Based Conferencing Solutions Deployment Guide SVC Encryption SVC media streams are encrypted using SRTP protocol with AES 128 encryption. The SIP signaling is encrypted using SIP over TLS secured signaling. SVC encryption is supported in both SVC conferences and mixed AVC CP and SVC conferences. Optimizing Video Traffic To reduce the computational and network resources used by a sending endpoint, the MCU optimizes the amount of uplink video traffic to endpoints in the conference. Endpoints that do not need to receive video streams, such as enabling the Pause Video option, will have video streams suspended from being sent to these endpoints. The sending endpoint only transmits the negotiated simulcast video stream that is actually requested by the other endpoints in the conference. This enables the endpoint to save CPU usage needed to encode the simulcast streams in addition to the uplink bandwidth. Only streams that should be relayed to the downlink are received. The total uplink bandwidth is reduced, making the endpoints less susceptible to network problems, such as jitter, packet loss, and traffic congestion. This video traffic optimization procedure applies only to the uplink of video and has no affect on video downlink, conference behavior, audio streams, or speaker change. B2B Support using the RealPresence SVC-Based Conferencing Solution Business-to-Business (B2B) conferences are supported in the RealPresence SVC-based Conferencing solution. The RealPresence SVC-based conferencing solution provides multiple Polycom UC environments to communicate with each other to establish conferences using Polycom s SVC technology. Mixed AVC CP and SVC conferences are supported for B2B conferences. The following diagram illustrates an example of Polycom B2B support: Polycom, Inc. 9

14 Polycom RealPresence SVC-Based Conferencing Solutions Deployment Guide In this B2B diagram example, multiple enterprises can connect to conferences outside the enterprise environment. Using the Polycom RealPresence Access Director (RPAD) for secured firewall traversal in the enterprise environments, the environments can be configured to communicate with one another s peers in a federated list. After the RPADs of each enterprise have been configured to accept calls from the other enterprises, the following call scenarios can be implemented: A conference participant from one enterprise can call a Virtual Meeting Room (VMR) of another enterprise A participant from one enterprise can call another participant in another enterprise A participant from one enterprise can call a remote participant in another enterprise A remote participant from one enterprise can call a VMR of another enterprise A remote participant from one enterprise can call a participant in another enterprise A remote participant from one enterprise can call anther remote participant from another enterprise Detecting SVC/SIP Endpoint Disconnections When an abnormal disconnection of SIP endpoints occurs because of network problems or client application failures, SIP endpoints remain connected to the conference and cause connection disruptions. For example, the video freezes in the layout or blocks content for SIP endpoints when a quick re-connection is performed. It can take several minutes to detect the SIP endpoint disconnection using the SIP standard behavior. Polycom, Inc. 10

15 Polycom RealPresence SVC-Based Conferencing Solutions Deployment Guide To detect the disconnection of SIP endpoints in a reasonable amount of time, a new system flag can be defined to specify the amount of time that the MCU should wait for an RTCP or RTP message from the SIP endpoint before the endpoint starts the disconnection process. The system default value is automatically set to 20 seconds. The system flag, DETECT_SIP_EP_DISCONNECT _TIMER, contains the amount of time in seconds to wait for an RTCP or RTP message to be received from the endpoint. When the time that was set in the system flag has elapsed and no RTCP or RTP audio or video message has been received on either the audio or the video channel, the MCU disconnects the SIP endpoint from the conference. A CDR event record is created with a Call Disconnection Cause of SIP remote stopped responding.

Software upgrades to the various Polycom components are performed Polycom, Inc. 19

24 Polycom RealPresence SVC-Based Conferencing Solutions Deployment Guide to provide deployment of SVC-based conferencing, enabling the enterprise to keep their initial investments and upgrading costs to a minimum. POCN, Cisco TIP, ISDN, PSTN, and H.323 are supported in the RealPresence Collaboration Server (RMX) for AVC-based conferences. ISDN and PSTN are not supported in the RealPresence Collaboration Server (RMX) 800s/Virtual Edition. The RealPresence Collaboration Server (RMX) automatically assigns AVC and SVC resources and can be expanded as needed. Upgrading the RealPresence Collaboration Server (RMX) software enables managing and operating SVC-based conferences, mixed AVC CP and SVC conferences, and AVC-based conferences. SVC-based conferencing requires that the RealPresence DMA be used as a SIP Proxy server and as the conference focus (for example, use RealPresence DMA VMRs and not RealPresence Collaboration Server (RMX) meeting rooms). Polycom s SVC-based conferencing solution does not require any special training and does not require changing existing dial plans. SVC-based conferencing possess exceptional audio quality Polycom s proprietary Scalable Audio Coding (SAC) is supported.

The following table describes the SVC support for each type of endpoint: SVC Support for Endpoints Endpoint SVC Support RealPresence Desktop Sends and receives up to 720p30 Layout up to 1+10 Content is added to the layout (double-click to view full screen) RealPresence Mobile Receives up to 360p30 (for ipad2 and ipad3) Sends up to 270p at 15fps Layout up to 1+5 on ipad and up to 2x2 on iphone Content is added to the layout on ipad (double-click to view full screen) RealPresence Group Series Sends and receives up to 720p30 When sharing content, one monitor is used for content and one for people, but the configuration varies, depending on whether Self View is enabled and how many people are participating. When content is not shared, the configuration for both monitors is spread over both monitors, again depending on whether Self View is enabled and how many participants are in the call. Using a RealPresence Group Series 500 system, layouts can include up to 5 participants and/or content on 1 monitor or across 2 monitors. Using a RealPresence Group Series 700 system, layouts can include up to 7 participants and/or content on 1 monitor or across 2 monitors. RealPresence CloudAXIS Sends and receives up to 720p30 For more details on supported resolutions, refer to the Release Notes for the Polycom RealPresence CloudAXIS Suite (version 1.5 and later). Deploying the RealPresence DMA in the Enterprise Environment The RealPresence DMA is used as the primary video conferencing call controller. It provides conference management, call control, port signaling, and functions as the conference focus. The RealPresence DMA also communicates with the provisioning server to configure conferences, create virtual meeting rooms (VMR), and connects participants to conferences. The RealPresence DMA is used as the SIP Proxy server when making SVC-based calls. Upgrading the RealPresence DMA software to version 6.1 enables the enterprise deployment to keep the existing RealPresence DMA component and use the RealPresence DMA for SVC-based conferencing. Polycom, Inc. 21

26 Polycom RealPresence SVC-Based Conferencing Solutions Deployment Guide For more information on the RealPresence DMA, see the Polycom RealPresence DMA 7000 System Operations Guide. Deploying the RealPresence Resource Manager in the Enterprise Environment The RealPresence Resource Manager is an integrated scheduling and device management platform for video conferencing. The RealPresence Resource Manager handles the provisioning of the conference participant endpoints and the scheduling of video conferencing. It communicates with the enterprise s management applications and servers such as user authentication, DNS, and servers. The RealPresence Resource Manager replaces the CMA 4000/5000 in the SVC-based conferencing architecture. An existing CMA server may be used in an enterprise deployment, but with limited SVC-based conferencing support; for instance, the scheduling of SVC-based conferences is not supported.

A new Profile is created and added to the Conference Profiles list. Resource Capacities for Mixed CP and SVC Conferences In a mixed CP and SVC conference, video resources are allocated according to the MCU type and the transcoding pools (AVC to SVC and SVC to AVC) required to convert video streams. Transcoding pools are dynamically allocated. If the conference has only AVC (CP) endpoints, or SVC-only endpoints, no additional transcoding resources are required. This is compared to a regular AVC (CP-only) conference or an SVC-only conference. However, when the conference becomes mixed, the transcoding pools must be allocated. Note that pools are not released when the conference stops being a mixed conference. For example, after all the SVC endpoints leave the conference and only AVC endpoints remain, the conference is no longer mixed. By default, the transcoding pools convert the SVC stream of each SVC endpoint to an AVC stream with a resolution of 360p. The transcoding pools also perform a conversion of AVC streams from each AVC endpoint to SVC streams. Translations between different endpoints can be done without using the highest resolution, thus saving translation resources. CP video layouts in mixed CP and SVC conferences support standard resolutions, just as they do in non-mixed CP conferences. Taking these factors into consideration and the type of MCU deployed in the environment, the resource capacities for a mixed CP and SVC conference can vary. The following table describes an example of the resource capacity allocations for the RealPresence Collaboration Server (RMX): System Resources are now reported in terms of HD720p30 CP ports. One HD video port equals 3 CIF video ports. Resource Capacity Allocations Number of Available Ports Resource Type Mixed CP and SVC (HD) (Example) RMX x MPMx 20 AVC 90 SVC RMX x MPMx 40 AVC 180 SVC HD720p SD 30 fps) SVC Only Polycom, Inc. 55

60 Polycom RealPresence SVC-Based Conferencing Solutions Deployment Guide Number of Available Ports Resource Type RMX x MPMx RMX x MPMx CIF 30 fps) The first four resource types in the resource capacity allocations table are endpoints in a CP-only conference or a mixed CP and SVC conference before the actual resource allocations occur. In a mixed CP and SVC conference, video resources are used according to the amount of both AVC and SVC participants in the conference and according to the actual type of the conference - mixed CP and SVC conferences or CP only conferences. The ratio of resources in a mixed conference is one AVC HD (720p30) video resource to three SVC video resources, meaning for each AVC HD video resource, three SVC video resources can be allocated. In this resource capacity allocations example, the mixed CP and SVC conference can allocate a combination of AVC and SVC ports depending on the endpoints that are defined in the actual conference. For example, a conference can be defined as a mixed CP and SVC conference, but will only allocate resources as a mixed conference when both AVC and SVC endpoints join the conference. When there is only one resource type of endpoints participating in the conference, such as AVC or SVC, the resource allocations are assigned according to the type of endpoint. For instance, a mixed CP and SVC conference with HD endpoints assigned can have 60 or 120 ports allocated depending on the server configuration. When an SVC endpoint joins the conference, the conference becomes an actual mixed conference and the resource allocations are divided between the AVC and SVC endpoints. The Resource Report will reflect this by showing an increase in the resource usage. The following diagram illustrates the amount of AVC to SVC port resources used in a mixed CP and SVC conference: When viewing the Collaboration Server resource report for mixed CP and SVC conferences, the resource allocations are described in AVC HD720p30 units. A port ratio of 1 AVC HD port equals 2 AVC SD ports, which equals 3 SVC ports (in a non-mixed conference). Polycom, Inc. 56

61 Polycom RealPresence SVC-Based Conferencing Solutions Deployment Guide When the Collaboration Server reports the available capacity, it appropriately rounds up the remaining capacity to the nearest whole value of available ports. For example, one SVC endpoint in a conference is equal to 1/3 of the resource value. The resource report displays this as one full resource used. Two SVC endpoints is equal to 2/3 of the resource value. Therefore, the resource report displays this as one full resource used, and so forth. The following table explains the actual resource capacity utilization for both CP only and mixed CP and SVC conferences: Resource Capacity Allocation Per Port Type Port Type Non-Mixed Conferences Mixed CP and SVC Conferences AVC HD * AVC SD * AVC CIF * SVC * Resources are consumed at this rate only after the conference contains mixed endpoints. Resource Capacity Utilization Per Port Type per MPMx Card Port Type Maximum number of licences Maximum Ports in Non-mixed Conferences 30 Maximum Ports in Mixed CP and SVC Conferences AVC HD AVC SD AVC CIF SVC The Resource Capacity Utilization table indicates the total amount of ports used for each port type for one MPMx media board in full capacity. The following diagram displays the RealPresence Collaboration Server (RMX) Resource Report, displaying a resource graph that indicates the number of voice and video ports that are available or occupied in the MCU. Polycom, Inc. 57

62 Polycom RealPresence SVC-Based Conferencing Solutions Deployment Guide Configuring the RealPresence Collaboration Server (RMX) 800s/Virtual Edition for Mixed AVC CP and SVC Conferences The RealPresence Collaboration Server (RMX) 800s/Virtual Edition can be configured for mixed AVC CP and SVC conferences, in addition to AVC CP-only conferences. To configure a mixed AVC CP and SVC conference: 1 In the RealPresence Collaboration Server Management pane, click Conference Profiles. 2 In the Conference Profiles pane, click the New Profile button. The New Profile - General dialog box is displayed. Polycom, Inc. 58

63 Polycom RealPresence SVC-Based Conferencing Solutions Deployment Guide By default, the Profile is set to the CP and SVC conferencing mode. 3 In the Conferencing Mode list, ensure that CP and SVC is selected to define a mixed CP and SVC conference. 4 Define the rest of the Conference Profile parameters for the mixed AVC CP and SVC conference as detailed in the RealPresence Collaboration Server (RMX) 800s/Virtual Edition Administrator s Guide. Resource Capacities for Mixed CP and SVC Conferences In a mixed AVC CP and SVC conference, video resources are used according to the number of both AVC and SVC participants connected to the conference. The ratio of resources in a conference is one AVC HD (720p30) video resource to three SVC video resources, meaning that three SVC video endpoints consume one AVC HD resource. The following table describes the resource capacity allocations for the RealPresence Collaboration Server (RMX) 800s per resource type. Resource Capacity per Resource Type Resource Type Number of Resources VoIP Ports 120 CIF Ports 40 SD Ports (4CIF) 40 HD 720p30 Ports 20 VGA RTV Ports 20 SVC Only Ports 60 Polycom, Inc. 59

64 Polycom RealPresence SVC-Based Conferencing Solutions Deployment Guide For example, the RealPresence Collaboration Server (RMX) 800s with 20 AVC HD resources can support a single conference with 10 HD (720p) AVC endpoints and 30 HD (720p) SVC endpoints. The following figure illustrates the number and ratio of AVC to SVC endpoints that can be simultaneously connected to the MCU. Resources - AVC to SVC Endpoint Ratio Resource Report When viewing the Collaboration Server resource report, the resource allocations are described in AVC SD/CIF units. A port ratio of 1 AVC HD port will equal 2 AVC SD ports, which equals 3 SVC ports. This signifies that when the Collaboration Server is reporting the available capacity, it appropriately rounds up the remaining capacity to the nearest whole value of available ports. For a detailed description of the Collaboration Server resource report, refer to the RealPresence Collaboration Server (RMX) Administrator s Guide. Configuring the RealPresence DMA This section describes how to configure of the RealPresence DMA for SVC-Based conferences and mixed CP and SVC conferences.

67 SVC-Enabled Conference Calls This chapter describes how to place an SVC-enabled conference call using the RealPresence SVC-Based conferencing solution. It describes the conference call from the end-user perspective, in addition to describing the SVC-enabled conference established in the RealPresence Collaboration Server (RMX) and the RealPresence Distributed Media Application (DMA). The chapter also describes the various features used in SVC-enabled conferences. Using the RealPresence SVC-Enabled Endpoints The Polycom RealPresence SVC-enabled endpoints provide full support for SVC-based conferences in addition to AVC-capable conferences. The RealPresence SVC-enabled endpoints include: RealPresence Desktop Supports Microsoft Windows and MAC (OSX). RealPresence Mobile Provides video conferencing for tablets and smartphones, extending video beyond conference rooms, enabling organizations to deliver video collaboration to more users in more environments. RealPresence Group Series Provides high quality video and sound and use the most up-to-date video communications technology to deliver the most natural video conferencing experience. RealPresence CloudAXIS Supports SVC conferencing on version 1.5 and higher. Configuring the RealPresence Group Series You can configure the RealPresence Group Series systems to make and receive SVC-enabled calls when the RealPresence Group Series system is connected to an SVC-capable bridge. You can enable or disable SVC calls in the RealPresence Group Series systems from the Dialing Preferences screen in the administrator s web interface. To enable or disable SVC calls: 1 In the RealPresence Group Series administrators web interface, navigate to Admin Settings > Network > Dialing Preference. Polycom, Inc. 63

68 Polycom RealPresence SVC-Based Conferencing Solutions Deployment Guide 2 Under Dialing Options, select one of the following settings from the Scalable Video Coding Preference (H.264) list: SVC Setting SVC then AVC AVC Only Description This is the default setting. This setting allows the system to determine whether the Virtual Meeting Room (VMR) is defined as SVC or AVC and enters the calls accordingly. When the conference is an SVC-capable conference, the system defines the call as SVC. When the conference does not have SVC capabilities, the system defines the call as AVC. This option disables SVC and allows AVC only calls. Making a Conference Call You can make point-to-point or multipoint calls using the SVC-enabled endpoints: Point-to-Point Calls Multipoint Conferences Point-to-Point Calls Using the RealPresence Desktop or the RealPresence Mobile applications, the participant can initiate a point-to-point call by: Selecting a participant from the Contacts list (LDAP access from the provisioning server or a manually entered contact) Selecting a participant from the Recent Calls list Typing the IP address of the participant to be called. SVC point-to-point SIP calls are only supported by the RealPresence Desktop or RealPresence Mobile applications. When the RealPresence Desktop is provisioned using the RealPresence Resource Manager, the Contacts list is comprised of the LDAP directory and contacts that have been manually added. When selecting a participant from the Contacts list, the call is started when the called participant answers the call. The RealPresence Access Director, the Polycom secure firewall solution, enables high-quality and secure unified communications with remote enterprise users and guest users in the enterprise. In this solution, the RealPresence Access Director system, acting as the Session Border Controller (SBC) for the enterprise IP network, secures the borders to the enterprise IP network, the private VPN, and the Internet. This allows for secure communication between the enterprise environment and enterprise remote users. The RealPresence Access Director enables external, remote users via designated video endpoints such as smartphones and tablets, to make an LDAP connection to the RealPresence Access Director system which are then proxied to the internal LDAP server. Polycom, Inc. 64

69 Polycom RealPresence SVC-Based Conferencing Solutions Deployment Guide The RealPresence Distributed Media Application (DMA) establishes point-to-point conferences within the enterprise network and is used as the SIP proxy server between the conference participants. The RealPresence Distributed Media Application (DMA) provides call control for point-to-point calls. When the point-to-point video call is sent to an endpoint outside the enterprise firewall, SIP signaling and media are sent through the RealPresence Access Director. Video Layouts for Point-to-Point Calls The video layout for point-to-point calls contain both participants in the layout view. The smaller pane displays the local participant (self-view). The following table illustrates how participants are displayed in the video layout of a point-to-point call: Number of Participants RealPresence Desktop RealPresence Mobile 1-2 Multipoint Conferences For SVC-based conferences, only SVC-enabled endpoints can connect to a configured SVC-Only conference on the RealPresence Collaboration Server (RMX) and the RealPresence Distributed Media Application (DMA). Supported SVC-enabled endpoints are as follows: RealPresence Desktop RealPresence Mobile applications RealPresence Group Series systems RealPresence CloudAXIS Non-SVC-enabled endpoints are not able to connect to SVC-Only conferences. SVC-based conferences are established on the RealPresence Distributed Media Application (DMA) through virtual meeting rooms. Participants to SVC-based conferences can dial-in to the virtual meeting room using a SIP URI, SIP IP address, or a virtual meeting room number. Examples of these can be: SIP URI SIP IP Address Meeting Room VMRs can also be located in the Contacts list when the RealPresence Resource Manager is connected with the enterprise LDAP. The RealPresence Resource Manager controls the provisioning of the enterprise computers. The RealPresence Distributed Media Application (DMA) is used for call control, SIP proxy, and conference management. The RealPresence Distributed Media Application (DMA) allocates a RealPresence Collaboration Server (RMX) for sending and receiving video streams to and from the SVC-enabled endpoints. When the RealPresence Collaboration Server (RMX) is allocated, it detects the type of Polycom, Inc. 65

70 Polycom RealPresence SVC-Based Conferencing Solutions Deployment Guide conference - SVC Only or Mixed CP and SVC. In an SVC Only conference, the RealPresence Collaboration Server (RMX) verifies that all endpoints support SVC capabilities and allows SVC-enabled endpoints to connect. When an endpoint in the conference is not an SVC endpoint, the RealPresence Collaboration Server (RMX) rejects the call and does not allow it to connect to the conference. In a mixed CP and SVC conference, both AVC-capable and SVC-enabled endpoints can connect to the conference. The conference uses the SVC protocol until an AVC-capable endpoint joins the conference. The conference then uses the AVC protocol. The RealPresence Collaboration Server (RMX) provides the information on the SVC streams for each endpoint in the SVC-enabled conference and negotiates the required video streams to be sent to the endpoints. Using the RealPresence Desktop, the RealPresence Mobile, or the RealPresence Group Series applications, the user can dial into VMRs or to other participants, view other participants in a continuous presence video layout, control video suspend and resume, audio mute, and share content. Video Layouts in Multipoint Conferences Depending upon the number of participants in the multipoint conferencing, video layouts are automatically configured for displaying on the participant endpoint. The participant who is currently speaking is displayed in the larger video pane and the previous active speakers are displayed in the smaller video panes. RealPresence Desktop and the RealPresence Mobile Using the RealPresence Desktop and the RealPresence Mobile applications, conference participants can control the appearance of video layouts. The participant can select a video frame in the video layout to enlarge the frame for a full frame view with a higher resolution. RealPresence Group Series In comparison to the RealPresence Desktop and RealPresence Mobile applications which support one monitor, the RealPresence Group Series systems can support both a single monitor or dual monitors. Dual monitors provide more flexibility in the video layouts, enabling you to view the active speaker or content on the second monitor. Continuous Presence in RealPresence Group Series Calls Continuous Presence mode shows multiple sites simultaneously on the near and far site screens in a video conference. The multipoint processor in this mode takes the streams from the different endpoints and puts them together into a single video image. In this mode, the MCU normally sends the same type of images to all participants. These images are called video layouts and can vary depending on the number of participants in a conference. When you use two monitors on the RealPresence Group Series systems, you can display up to eight video streams at the same time. The exact number of streams you can display depends upon your system configuration and capability. When sharing content, one monitor is always used for content and one for people. However, the configuration can vary, depending upon whether you have enabled Self-view and how many people are participating in the call. When you are not sharing content, the streams can be spread over both monitors, depending upon whether Self-View is enabled and how many participants are in the call. For more information on the RealPresence Group Series video layouts, see Video Layouts for RealPresence Group Series Conferences. Polycom, Inc. 66

71 Polycom RealPresence SVC-Based Conferencing Solutions Deployment Guide Video Layouts for RealPresence Desktop or RealPresence Mobile Conferences The following video layouts are used in an SVC-enabled conference and a mixed CP and SVC conference using the RealPresence Desktop or RealPresence Mobile clients. This table illustrates how participants are displayed in video layouts in an SVC-based conference: Number of Participants RealPresence Desktop RealPresence Mobile Polycom, Inc. 67

72 Polycom RealPresence SVC-Based Conferencing Solutions Deployment Guide Number of Participants RealPresence Desktop RealPresence Mobile Video Layouts for RealPresence Group Series Conferences The RealPresence Group Series can be configured to connect using AVC only mode, or to first try to connect using SVC. For more information on configuring the RealPresence Group Series, see Configuring the RealPresence Group Series. Available video layouts in the RealPresence Group Series depend upon whether you are using a single video display monitor or dual video display monitors. Self View can be displayed or hidden by using the RealPresence Group Series systems settings. AVC-Only Conferences The maximum number of participants is 5 for RealPresence Group Series 500 and 7 for the RealPresence Group Series 700. SVC-Only Conferences The maximum number of participants is 7 (plus 1 for Self View). For the RealPresence Group Series 300 and the RealPresence Group Series 500 systems, when there are more than six participants in a conference, the video layouts remain the same layout as specified for six participants. Using a Single Video Display Monitor and Showing No Content The following table displays the video layouts without content using a single monitor: Polycom, Inc. 68
