Deutsche Telekom Expands HDTV Service With Harmonic's New Electra® 8000 Universal Encoder

SUNNYVALE, Calif. — Sept. 10, 2009 — Harmonic Inc. (NASDAQ: HLIT) today announced that Deutsche Telekom AG, one of the world's leading telecommunications service providers, has selected Harmonic's recently introduced DiviCom Electra® 8000 universal broadcast encoder to expand the MPEG-4 AVC (H.264) HD video service to its T-Home Entertain subscribers throughout Germany. With this deployment, T-Home Entertain can offer its subscribers the largest number of HD channels in Germany, a significant competitive advantage. As service provider for Deutsche Telekom AG, MTI is responsible for the contribution of video signals from its Munich/Ismaning site where the company operates its compression equipment.

Deutsche Telekom selected the Electra 8000, the world's first 1-RU encoder with multi-resolution, multi-standard, multi-service and multi-channel capabilities, because of its unrivalled versatility, enhanced video quality and significantly improved bandwidth efficiency.

"Harmonic's digital video solutions combine the best feature set with the highest HD quality," said Dieter Engel, Senior Vice President at Deutsche Telekom AG. "With the new Electra 8000, we can further enhance the HD service for our subscribers and also put in place a scalable, dense and power-efficient platform. The Electra 8000 delivers a significant reduction in bit-rates for our T-Home service, which allows us to extend subscriber reach, while also providing higher video quality."

"With the increasing availability and uptake of HD content in Europe, Harmonic is working with new and existing customers, such as Deutsche Telekom, to expand their HD services," said Arnaud Perrier, Senior Manager of Encoder Product Marketing at Harmonic Inc. "The fact that these customers are selecting Electra encoders is indicative of the versatility and technical excellence of our compression systems to enable more advanced services and significantly improve video quality while consuming considerably less bandwidth."

A number of cable, satellite and telco service providers in North America and Europe have selected the Electra 8000 for SD MPEG-2, HD MPEG-2 and HD MPEG-4 video services.

The Electra 8000 provides up to four standard definition (SD) or high definition (HD) channels of superior quality constant bit-rate (CBR) or variable bit-rate (VBR) video using either MPEG-2 or MPEG-4 AVC encoding, and can reduce bit-rates by 20 percent. The Electra 8000 also features integrated statistical multiplexing and a built-in broadcast quality up/down converter for differentiated services such as an HD broadcast of the premium SD lineup. This groundbreaking architecture, which can be easily upgraded with a variety of firmware options, eases operational requirements of density and power efficiency, and facilitates the launch of new value-added video services.
