"We are excited to be working with RADVISION to bring video-based personal communications to the Set Top Box," said William O. Leszinske, Jr., General Manager of Intel's Consumer Electronics Group. "Consumers have more choices than ever before with new services, such as video phone and video conferencing. Intel's new media processor enables the delivery of these services to the home while providing headroom for future services." RADVISION's Multimedia Terminal Framework allows application developers to focus on application development, hardware integration and user interaction rather than complex VoIP standards when developing IP Set Top Boxes, as well as other Customer Premise Equipment (CPE) devices, such as wireline and wireless terminals, IADs, and mobile handsets. This enables faster time-to-market. The framework is a complete solution; encompassing signaling, call control and media management. RADVISION is developing the entire videoconferencing application for Intel's media processing platform, integrating third party audio and video codecs with the platform's peripherals, and developing a reference application for OEMs. This is enabling rapid development and short time-to-market, while maintaining high flexibility and extensibility. "At RADVISION we believe that the IP STB will soon be the epicenter of communications in the home," added Zeev Bikowsky, General Manager of RADVISION's Technology Business Unit. "IP-based videoconferencing technology opens the door to an unlimited number of new, compelling value-added services for the digital home, based on strong networked media platforms like Intel's. RADVISION's ability to offer a complete solution will help operators build these services."
