RADVISION and SPIRIT pre-integrate their technologies on the TI Davinci Platform providing an interactive video enabling technology subsystem that slashes product development time

TEL AVIV (October 30, 2007) –

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, and SPIRIT DSP (http://www.spiritdsp.com/), the world’s leading provider of embedded voice and video software products, today announced further cooperation in porting their solutions on Texas Instruments’ DaVinci(TM) converged media platform.

OEMs are successfully developing TI’s DaVinci-based STBs and multimedia devices that support real-time communications and IMS services, such as video sharing, presence/messaging, push-to-talk, and video conferencing, that deliver very high quality and reliability. The RADVISION’s Multimedia Terminal Framework and SPIRIT’s TeamSpirit® 3.0 Voice&Video Engine Embedded come pre-integrated with easy-to-start examples on how to speed up solution development.

Texas Instruments uses RADVISION’s Multimedia Terminal Framework, an open framework that combines flexible and cost-effective integration of converged applications – from IP Set-Top-Boxes (IPSTBs) and video telephony to portable multimedia players. The RADVISION Multimedia Terminal Framework delivers the support required for call control services and multiple terminations. With advanced call control services, support for a wide range of SIP specifications, multiple terminations support, and “out-of-the-box” ease of use, the Multimedia Terminal Framework is an ideal solution for developers of IMS networks, equipment and devices.

Texas Instruments uses TeamSpirit® 3.0 Voice&Video Engine Embedded that is a highly optimized media processing solution which enables real-time voice & video-over-IP calls. The solution is IMS-ready, so new revenue generating applications and services can be implemented on wireline or wireless devices. The engine supports miscellaneous signaling protocols, is adapted to deliver the good quality over any network conditions and thus can be used on any network, including Wi-Fi and 3G.

“Both technologies supplied by our partners, enable development of next generation DaVinci-based consumer products including state-of-the-art video features with closer, clearer and crisper video quality. Today’s users demand more than standard TV, they want excellent video call capabilities as well. With SPIRIT and RADVISION, DaVinci enables this perfectly,” says Arnaud Duclap, EMEA business development manager, Digital Entertainment, Texas Instruments.

“SPIRIT’s engines aim to deliver the highest-quality voice and video to converged communication devices,” says Slava Borilin, VP Products at SPIRIT. “We have a strong pipeline of OEMs looking to license our voice/video engines for the DaVinci platform. We are pleased to collaborate with RADVISION and TI, and together believe we are setting a new quality standard for audio-visual communications.”

“RADVISION and SPIRIT have cooperated since our initial choice of SPIRIT solutions in our developer products,” says Adi Paz, Senior Director for Marketing and Product Management with RADVISION Technology Business Unit. “Together with TI, we are bringing new video telephony capabilities to the world of next generation IMS-ready consumer electronics, such as IP-STBs, portable multimedia players, media centers and more.”
