High Definition Video Engine from RADVISION and TI Allows Developers to Create
Interactive Video Telephony Products

Solution offers developers a fast and cost-effective path to embed high
definition video communications

Wednesday March 25, 2009, 8:00 am EDT

TEL AVIV, Israel--(BUSINESS WIRE)--Texas Instruments Incorporated (TI), and
RADVISION(R) Ltd. (Nasdaq: RVSN - News), a leading provider of video network
infrastructure and developer tools for unified visual communications over
Internet Protocol (IP) networks, 3G and emerging next-generation IP Multimedia
Subsystem (IMS) networks, today announced their commitment to high-definition
video communications. This effort and the resulting solution enable developers
to build high end, high-definition interactive video terminals at a cost that is
considerably lower than that of today's solutions.

The RADVISION and TI solution is suitable for the development of video
communications enabled devices for both consumer electronics and enterprise
markets. These devices include products such as television sets, projectors,
video phones, enterprise room systems, set-top boxes, LCD monitors, surveillance
products, netbooks and digital photo frames.

This solution is comprised of TI's video communications demo board, a design
incorporating TI's TMS320DM6467 and TMS320DM6437 digital media processors based
on DaVinci(TM) technology and RADVISION's BEEHD, a High Definition interactive
video engine for developers.

TI's DM6467 allows simultaneous video encoding and decoding at 720p resolution
and up to 30 frames per second. It is designed to support high-definition video
communication solutions at a low bill of materials (BOM) cost.

"This effort presents a unique opportunity to bring high quality and cost
effective interactive video to the market, thus easily making any device a
videoconferencing device," said Adi Paz, Vice President Products and Business
Development for RADVISION Technology Business Unit. "TI's DM6467 digital media
processor is a cost effective solution and has enabled us to provide a high
quality video conferencing terminal engine to customers."

RADVISION's BEEHD is a revolutionary and unique software platform that handles
all video telephony requirements: from signaling and call control to media
components. With media quality and user experience in mind, BEEHD incorporates
special mechanisms to reduce latency, improve video quality over internet
connections, and makes it easy to install and manage.

"RADVISION was the right choice when we decided to bring a high-end and complete
interactive video solution to our customers," said J.B. Fowler, Video
Communications Business Manager, Texas Instruments. "RADVISION's unique
experience and vast knowledge in both video coding and VoIP technologies enables
us to provide a high quality solution that is unparalleled in the market."

RADVISION is developing the entire video engine for TI's digital media
processors. This includes specialized mechanisms built into the codecs and the
media system for improving media quality and developing a reference application
for OEMs. This enables rapid development and short time-to-market, while
maintaining high flexibility and extensibility. The solution incorporates all
required components leaving only minimal mandatory effort, such as GUI design
and integration, for OEMs.
