Video ConferenCinG SerViCeS
- 1. Video ConferenCinG SerViCeS Video conferencing is a powerful communications tool in the modern business world. The ability to share important business discussions with body language and facial expressions delivers enormous benefits compared to any other conferencing medium. In many ways, video conferencing has truly become “the next-best thing to being there.” The enterprise video conferencing market has traditionally been supplied by a handful of suppliers of complete video conferencing solutions consisting of the vendor’s own video-enabled terminals or desktop software clients integrated with a centralized Video MCU (Multimedia Conferencing Unit). Video MCU products are typically proprietary integrations of the video conferencing application and the underlying video processing hardware. These solution-based video conferencing offerings limit third-party feature enhancements, and constrain the reuse of the video processing resources with other applications. The result is a relatively expensive single- service solution with limited flexibility to integrate into broader enterprise unified communication service capabilities. radiSyS ConVedia Media SerVerS Support open ip-BaSed Video ConferenCinG SolutionS RadiSys Convedia media servers are bringing open VoIP architecture benefits and cost efficiencies to the video communications development community. In a next-generation video conferencing solution using a RadiSys Convedia media server, the functions of a traditional MCU are decomposed and replaced with individual “best-of-breed” functional components, which are interconnected using open, standards-based interfaces. Video application and signal processing are now hosted on an application server, which is functionally separated from the actual video media packet processing. RadiSys Convedia media servers provide powerful video conferencing modes and features based on leading video and audio codec standards and file formats; this maximizes the interoperability with open video-enabled terminals, soft-clients, and 3G phones. The application server controls the RadiSys Convedia media server using SIP and Media Server Markup Language (MSML), a powerful and extensible SIP-based control interface specifically designed for feature-rich IP media server control.

RadiSys Convedia media servers bring to SIP audio application developers worldwide the opportunity to economically add video features to their solutions, accelerating their ability to introduce and integrate feature-rich IP video conferencing capabilities into a unified communication solution. The result is an improved business case for the widespread rollout of video conferencing capabilities, which will drive the migration and benefits of collaborative multimedia conferencing solutions out of the purpose-built, expensive video conference rooms of the past, and towards the desktops, mobile laptops, and 3G mobile phones of future video-enabled organizations and online communities. VoiCe-aCtiVated SwitChinG SiMple, CoSt-effeCtiVe Video ConferenCinG for MoBile and enterpriSe MarketS RadiSys Convedia media servers support two modes of video conferencing. Voice-Activated Switching (VAS) bridges multiple participants into a video conference, where everyone would see an identical real-time video stream of the active speaker. Audio-only participants could also be added into the same conference mix. As the active speaker changes, the media server “switches” from one video-enabled participant to another. Alternatively, conference floor control allows the application server to designate a specific conference participant as the sole source of video in the conference. VAS is particularly beneficial for video conference participants using 3G mobile phones, where limited screen size makes multi-pane displays impractical. ContinuouS preSenCe iMMerSiVe Video ConferenCinG CapaBilitieS for Sip appliCation deVeloperS The second supported mode is Continuous Presence. With the RadiSys Convedia Media Server, the SIP application developer can establish a video conference where multiple real-time video streams are displayed in a multi-pane continuous presence display. Continuous presence also has a voice-activated border feature which highlights the current speaker in the display. All video conferencing modes also support video announcements and video conference recordings, along with RadiSys’s industry-leading audio conferencing features and capabilities including N-Loudest mixing, automatic gain control, personalized mixing (for example, each participant could view or hear different participants), and active speaker notification to the application server. | www.radisys.com
