Harmonic Announces ProView 7000 Integrated Receiver and Stream Processing Platform

Sunnyvale, Calif. — April 17, 2009 — Harmonic Inc. (NASDAQ: HLIT) today introduced the ProView™ 7000 integrated receiver and stream processing platform — the world's first solution to combine a scalable video receiver, DVB descrambler, multiformat decoder and MPEG stream processor in a single rack unit. The versatile and modular ProView 7000 paves the way for content providers, broadcasters, cable MSOs and telco operators to cost-effectively deploy today's most advanced distribution and contribution applications.

"We are seeing positive results from the addition of Scopus Video Networks' technologies to Harmonic's family of solutions, as evidenced by the introduction of the ProView 7000," said Nimrod Ben-Natan, vice president of product marketing, solutions and strategy for Harmonic Inc. "With its flexibility and multi-functional capabilities, this platform fits right in with Harmonic's philosophy of helping operators maximize their return on investment with IP-based solutions from satellite reception all the way to end-user delivery."

Based on industry-leading Scopus integrated receiver/decoder (IRD) technology, the ProView 7000 is an outstanding solution for a large spectrum of content reception applications, including:

• Contribution and distribution applications: The ProView 7000 integrates seamlessly with Harmonic's contribution encoders to provide a low-delay link that is ideal for newsgathering applications.

• Re-encoding applications: The ProView 7000 decodes all formats and standards including MPEG-2 and MPEG-4 AVC (H.264) in both standard and high definition, giving operators of DBS and IPTV networks maximum flexibility in their choice of content compression formats.

• Digital turnaround: Cable operators can significantly reduce operating expenses by descrambling multiple programs within a single compact unit.

• All-IP headends: The ProView 7000 can act as a receiver to descramble and transmit DVB-S2 satellite signals to Harmonic's FLEX™ decoder blade for seamless encoding and enables the deployment of or migration to all-IP headend solutions. The entire video delivery infrastructure is easily managed and controlled using Harmonic's NMX Digital Service Manager™.

"By integrating transport stream descrambling, re-multiplexing and the ability to decode all formats and standards, the ProView 7000 helps service providers implement a scalable infrastructure that simplifies their operations and cuts capital and operating costs," said Yaniv Sibony, product marketing manager for Harmonic.

The new ProView 7000 platform will make its debut at the 2009 NAB Show in Las Vegas, April 20-23, in Harmonic's booth, #SU7209.
