Harmonic Inc. (NASDAQ: HLIT) today announced that two of its products have been honored for superior technical innovation in Broadband Gear Report's (BGR) 2009 Diamond Technology Reviews. Harmonic's ProStream(TM) 4000, part of the MediaPrism(TM) suite of tools for converged video delivery to any device, received a perfect score of five diamonds. According to BGR, a five-diamond rating indicates superb products that set new standards for performance and provide groundbreaking technical milestones. In addition, Harmonic's ProView(TM) 7000 integrated receiver and stream processing platform received an excellent rating with a score of four diamonds.

"The Harmonic MediaPrism Convergence Suite and ProStream 4000 Multi-Screen Transcoder garnered superlative rankings from this year's Diamond Technology Reviews panelists for the solution's ability to help operators resolve some of the most difficult integration issues pertaining to the delivery of voice, video and data services to multiple devices," Laura Hamilton, editor-in-chief at BGR, said. "They viewed the platform as very timely as the industry moves to capture new revenue from both fixed and mobile infrastructures."

The MediaPrism Convergence Suite with ProStream 4000 is the industry's most comprehensive TV everywhere solution, providing operators with a suite of tools for real-time and offline content creation, transformation and multi-screen video delivery to the TV, PC, iPhone and other mobile devices.

"The Diamond Technology Reviews judges applauded the Harmonic ProView 7000 Integrated Receiver and Stream Processor for its flexibility and space-saving features. They were impressed by the combination of a scalable video receiver, DVB descrambler, multi-format decoder and MPEG stream processor into only 1-RU," continued Hamilton.

The ProView 7000 integrated receiver and stream processing platform, receiving four-diamond recognition as an excellent product with technical features and performance that provide clear and substantial benefits, provides an ideal solution for digital turnaround processing (DTA), descrambling and decoding operations. The ProView 7000 platform features up to 2 DVB-S/S2 or 8VSB inputs, ASI and IP outputs in a compact and cost effective 1-RU system that reduces system costs as well as complexity.
