2 June 2010. RADVISION has announced a new Telepresence feature for the RADVISION SCOPIA Elite MCU that enables
multi-party communications between Telepresence systems
of different vendors in addition to standards-based videoconferencing endpoints.

The new RADVISION SCOPIA Elite MCU Telepresence feature enables multi-party videoconferencing with Cisco, Logitech/LifeSize, Polycom and TANDBERG Telepresence and any standards-based Videoconferencing System

RADVISION's new SCOPIA Elite Telepresence capability will be available in Q3 2010 as a software upgrade and will be demonstrated at the InfoComm 2010 Exposition in Las Vegas, June 9 -11, booth N2231 in the Conferencing Pavilion.

With the new RADVISION SCOPIA Telepresence feature, the SCOPIA Elite MCU can establish connections with Telepresence systems from Cisco, Logitech/LifeSize, Polycom and Tandberg, allowing Telepresence users to view all meeting participants in a multi-party call, including those on traditional video conferencing systems or Telepresence systems from other vendors.

Users with traditional video conferencing systems will see the telepresence participants in a special video layout where multiple video streams from a telepresence endpoint are combined into a single widescreen image. Telepresence users will also see other conference participants in a special video layout, adding to the Telepresence immersive video experience.

Roberto Giamagli, General Manager, Networking Business Unit of RADVISION, said:
"Telepresence users no longer have to be stranded in their closed solutions with SCOPIA Elite's new breakthrough interoperability technology. This new capability provides significant opportunities for enterprises and service providers to cost effectively deliver multi-party communications for Telepresence along with interoperability while retaining the Telepresence multi-stream experience."

RADVISION'S SCOPIA Elite MCU is the ideal platform to support Telepresence given the special handling and video processing required for Telepresence communications. The SCOPIA Elite utilizes the latest in high performance DSP technology and offers 1080p video capabilities yielding uncompromised High-Definition video multi-party support. Telepresence capabilities on the SCOPIA Elite MCU are enabled through a license key providing the ability for enterprises to migrate to Telepresence in a very simple and cost effective fashion, as opposed to purchasing and deploying an additional, expensive separate system.
