Harmonic's Rhozet™ Transcoding Technology Chosen by S4M to Streamline Newsroom Video Production

SUNNYVALE, Calif. — Aug. 6, 2009 — Harmonic Inc. (NASDAQ: HLIT) today announced that its Rhozet™ Carbon Coder™ universal transcoding solution has been selected by Germany-based S4M - Solutions for Media GmbH, a joint subsidiary of arvato systems and RTL Television, for its video production management system, VPMS. With the integration of Rhozet Carbon Coder, S4M is now offering its customers a flexible production system with video effects support. This capability is particularly useful for newsgathering organizations that need a quick way to add video effects, such as wipes and fades, within the VPMS solution.

Deployed by private and public service broadcasters throughout Europe, S4M's VPMS supports the management of digital video assets from acquisition through production to playout, distribution, and archiving. The integration of Rhozet Carbon Coder technology with S4M's VPMS streamlines the video production process for broadcasters where time-to-air is critical, letting them add video effects during the transcoding process to deliver compelling video content quickly.

"The collaboration with Rhozet was crucial for us to achieve our goal to enhance VPMS with video effects capabilities," said Holger Noske, S4M's VP digital media management. "Rhozet's engineering team has the extensive and necessary video technology expertise, and a proven track record that can help us bring this capability to the market."

"We were happy to help S4M provide their customers, who need to deliver video content under tight deadlines, the tools to do more than rough cuts. Now even a quickly produced news segment looks much more professional," said David Trescot, vice president of the Rhozet Business Unit at Harmonic Inc.

Rhozet Carbon Coder is a universal transcoding solution that facilitates the creation of multiformat video for Internet, mobile, and broadcast applications. As part of the transcode process, Carbon Coder handles an array of critical operations including SD/HD and PAL/NTSC conversion, logo insertion, graphics overlay, voice over, video and audio transitions, color space conversion, color correction, closed captioning extraction, teletext and subtitling handling. Multiple Carbon Coder nodes can be configured as a rendering farm to accelerate the workflow and provide automated processing for high-volume transcoding.
