Free SCOPIA Mobile V2 Now Available in Apple App Store, First to Support H.239 Data Collaboration for Connectivity with Standards-Based Video Conferencing and Telepresence Systems

TEL AVIV, Israel (December 07, 2010) – RADVISION® Ltd. (Nasdaq: RVSN), a leading technology and end-to-end solution provider for unified visual communications including video network infrastructure, developer tools and high definition (HD) room, desktop and mobile video conferencing systems, today announced the availability of SCOPIA Mobile V2, the first conferencing application for the Apple® iPhone® and iPad(TM) that allows users to participate in video conferences with standards-based audio and H.239 data collaboration.

SCOPIA Mobile V2 is available for free immediately through the Apple App Store. Two different versions of SCOPIA Mobile are offered. SCOPIA Mobile for the iPad is optimized for the large, high resolution display of the iPad; with SCOPIA Mobile for the iPhone optimized for the high resolution Retina(TM) display and the additional telephony capabilities of the iPhone.

SCOPIA Mobile users can now view presentations, spreadsheets, documents and images shared in a video conference or telepresence meeting with H.239 interoperable data collaboration. Participants can also immediately review previously shared materials if they arrived late to a meeting or spend additional time on critical points in material presented without interrupting other participants or disturbing the meeting flow. In addition, iPhone users can easily connect to a video conference and participate by audio through the telephony capabilities of the iPhone.

SCOPIA Mobile’s revolutionary data collaboration capabilities are based on RADVISION’s recently introduced SCOPIA V7.5 solution with advanced data collaboration. This new advanced data collaboration is the first in the video conferencing industry to provide users with extended capabilities beyond what the H.239 standard offers, along with video conferencing room and telepresence system interoperability.
