(Nasdaq: RVSN - News), a leading provider of video network infrastructure and developer tools for unified visual communications over IP, 3G, and emerging next-generation IMS networks, today announced that the company has been presented with the prestigious 2008 North American Frost & Sullivan Award for Product Differentiation Innovation. This Award is presented each year by Frost and Sullivan to the company that has best demonstrated the ability to develop products that allow it to differentiate from competing vendors and products. RADVISION received this award in recognition of the company successfully leveraging its existing technology assets to introduce SCOPIA Desktop that in combination with SCOPIA multi-point control unit (MCU) and the rest of the SCOPIA infrastructure suite, is allowing RADVISION to set itself apart in the industry. Unified Communications is driving the deployment of video conferencing throughout organizations from the conference room, to the desktop and to mobile workers. The SCOPIA Conferencing Platform supports all of those environments including next generation high definition (HD) endpoints, standard definition (SD) endpoints and through SCOPIA Desktop to the remote and mobile worker. SCOPIA Desktop capabilities have also been integrated into Microsoft's Office Communications Server 2007 and IBM Lotus Sametime collaboration solutions extending the capabilities of those solutions. "RADVISION's SCOPIA Conferencing Platform and the introduction of SCOPIA Desktop come at a critical time," said Roopam Jain, Frost & Sullivan's Principal Analyst - Conferencing & Collaboration. "Close to a hundred million U.S. workers are expected to telework by 2010 and companies are continually looking for ways to improve remote employee communication and collaboration and bring these teleworkers closer into the corporate culture. The SCOPIA Desktop solution achieves that with a unique blend of audio, video and data capabilities." "To efficiently meet the needs of today's enterprise requires a standards based solution that supports the existing install base of video devices and one that extends videoconferencing beyond them to remote workers," said Boaz Raviv, RADVISION's CEO. "The solution has to have freely distributable software clients, have the capability to traverse firewalls, has to be easy to install and use and provide data collaboration and video features that are compatible with other video conferencing devices being used by the company. RADVISION has addressed all those requirements with the SCOPIA Conferencing Platform and SCOPIA Desktop."
