WTVS Detroit Public Television Deploys Terayon Digital Video Broadcast Platform

Santa Clara, California - August 29 2005

Terayon Communication Systems, Inc. (NASDAQ: TERN), a leading provider of digital video networking applications and home access solutions, today announced that WTVS Detroit Public Television (DPTV) has become the first public television station to deploy the Terayon BP 5100 as part of its commitment to High Definition TV (HDTV) broadcasts.

DPTV is initially deploying the BP 5100 to switch between local and national HD feeds; insert high-quality, real-time graphic overlays into HD programming; and reduce bit rates to accommodate both DPTV’s new HD channel and the legacy standard definition television (SDTV) feed – all without decoding and re-encoding the underlying content. The BP 5100’s streamlined approach reduces equipment and operational costs and preserves picture quality as decoding and re-encoding steps are eliminated.

“As a station that relies primarily on voluntary contributions, we needed to find a solution that would maintain the native video quality and Dolby digital sound of our HD programming without the need for costly equipment and complex systems integration,” said Helge Blucher, Vice President, Engineering and Technology for Detroit Public Television. “The Terayon BP 5100 was the only solution that could elegantly meet our needs without decoding digital feeds to baseband for processing, and then re-encoding them.”

“Detroit Public Television indicated to us that one of their primary goals was to create a consistent HD presence, rather than switching between formats and channels and forcing local cable providers to frequently modify their channel mapping and stream multiplexing,” said Kanaiya Vasani, Terayon Vice President of Marketing. “The BP 5100 provides the cost efficiencies and performance the station needs to support the fulltime HD and SD channels that best meet the needs of the station, local cable system operators and viewers.”

About the Terayon BP 5100
The Terayon BP 5100 platform provides broadcasters with exceptional capabilities for processing, managing and branding their digital video services and applications. These include graphical overlay of logos and ads, dynamic program switching, and insertion of programs and ads – in high and standard definition digital video. The BP 5100 utilizes Terayon’s pioneering real-time MPEG processing technology to composite video and graphics entirely in the compressed digital domain. Unlike traditional processes that require the video to be decoded to baseband and later re-encoded to digital – which degrades picture quality – the BP 5100 preserves picture quality and eliminates the need for additional costly equipment.
