TEL AVIV (October 22, 2009) –

RADVISION® Ltd. (Nasdaq: RVSN), 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 its latest version of its award winning SCOPIA Desktop V7.0, has been fully optimized with Microsoft® Windows® 7 and the latest Intel® technologies including the new high performance Intel® Core(TM) i7 and Intel® Atom(TM) Processors.

RADVISION’s SCOPIA Desktop fully supports high definition video at the desktop providing an uncompromised video experience for users wherever they are. However, HD video requires significantly more processing power than standard definition video. RADVISION, a Microsoft Gold Certified Partner and an Intel Software Partner Program member, has utilized the advanced technologies in both Windows 7 and Intel processors to provide the highest quality video and most efficient use of PC resources available.

SCOPIA Desktop V7.0 has been optimized to leverage Windows 7’s full support for advanced multi-core processing. This allows SCOPIA Desktop to fully separate processes such as audio, video and data encoding and decoding, network connectivity and encryption into multiple threads taking advantage of the Intel Core i7 and its intelligent multi-core technology. SCOPIA Desktop also utilizes the advanced graphic hardware acceleration fromto Windows 7. This capability particularly benefits users on netbooks with the Intel Atom Processor resulting in lower CPU utilization and better video performance. The ultimate combination of SCOPIA Desktop V7.0, Windows 7 and the Intel Core i7 deliver an exceptional HD video conference experience on a PC.

“Customers want the best video experience they can get regardless of where they are,” said Roberto Giamagli, General Manager, Networking Business Unit of RADVISION. “The optimization we have achieved in both Windows 7 and Intel processors provides our customers with the highest quality video and most efficient use of PC resources available.
