COMMIT Selects RADVISION(R) 3G-324M and RTSP Stacks for Its Latest TD-SCDMA Mobile Terminal Reference Design.

TEL AVIV, Israel -- RADVISION (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 that COMMIT Incorporated, a pioneer of TD-SCDMA wireless chipset solutions, is using the RADVISION 3G-324M Toolkit and RTSP Client Toolkit to develop a video-enabled 3G handset that is particularly suited for China's growing TD-SCDMA market.

"We selected RADVISION's technology because it takes a comprehensive approach to all the complexities of 3G video telephony," said Evan Yu, CEO of COMMIT. "RADVISION's technology is helping us deliver on the TD-SCDMA promise. We expect TD-SCDMA to go main-stream and rapidly increase market share once 3G services are officially deployed in China."

The new COMMIT mobile terminal reference design has realized stable high performance VT and streaming features. The RADVISION 3G-324M Toolkit is uniquely adept in enabling these features - with easy to use APIs, optimized CPU usage, patent-pending multiplexing technology, and many optional features that reduce time-to-market while optimizing interoperability. RADVISION's 3G-324M stack is part of the company's IMS client offering, which includes a video share application. This enables RADVISION customers to develop future-proof solutions and gain a head start on emerging IMS deployments.

"COMMIT's choice is further testimony to the flexibility and power of RADVISION's 3G technology," said Tsahi Levent-Levi, Product Manager for RADVISION's Technology Business Unit. "In places like China, where TD-SCDMA networks are just becoming the norm, handset and chipset developers are choosing the technology that will enable strong performance over any kind of network - both today and tomorrow."
