-- Audio-Visual Storage Manager Maximizes Performance and Durability in STB/DVR Applications --

CONSUMER ELECTRONICS SHOW 2007, LAS VEGAS – January 5, 2007 – Hitachi Global Storage Technologies (Hitachi) announced today it has developed new software technology targeted toward digital video recording (DVR) applications, including set-top boxes (STBs), that utilize hard disk drives. Hitachi’s AVSM™ software technology is designed to seamlessly manage the mix of high-definition video streaming and best-effort file operations, such as electronic program guides or background IPTV downloads present in STB applications. Through “smart” hard drive management, AVSM technology helps reduce duty cycle by up to 60 percent and eliminates disk fragmentation, ultimately helping to extend the life of the hard drive and the host STB system.

Today’s consumers increasingly use their digital cable and satellite set-top boxes to record high-definition programs and stream digital media from the Internet, and they want that content available throughout the house. However, recording and playing back a high number of multiple programs, or streams, can place greater demands on the hard drive and the conventional STB file system.

“Hitachi is continually looking for ways to add value to our hard disk drive solutions. We will see a steady ramp in HDTV viewership and programming in the coming years, and the demands placed on the DVR set-top box will increase significantly,” said Marcia Bencala, vice president, corporate strategy and product planning, Hitachi Global Storage Technologies. “Leveraging Hitachi’s R&D efforts, we’ve developed AVSM technology to be complimentary to our hard drive solutions--to help address the quality and performance issues that are faced by STB OEMs and content service providers.”
