SAN ANTONIO--(BUSINESS WIRE)--June 5, 2002

Harmonic Inc. (Nasdaq:HLIT) today announced that Charter Communications, Inc. (Nasdaq:CHTR) has selected the new Broadcast Network Gateway(TM)(BNG) to access and distribute high-definition (HD) programming. By deploying BNG systems in its cable headend facilities, Charter is able to give Charter Digital Cable(R)customers in five markets the ultimate viewing experience with premium HD programming.

"The adoption of digital television is accelerating and, in particular, considerable attention is focused on high-definition services. Consumers are finally able to enjoy the superior color, picture and audio quality available with HD programming," said John Pietri, Charter Senior Vice President of Engineering. "Harmonic's Broadcast Network Gateway is a highly integrated, flexible and efficient solution for delivering premium HD content now available from pay TV and major broadcast television networks."

"In an increasingly competitive world, broadband service providers are looking to new options such as high-definition digital television and video-on-demand to improve differentiation and increase revenue," said Dr. Yaron Simler, President of Harmonic's Convergent Systems Division. "The Broadcast Network Gateway enables Charter to efficiently add HD television to their portfolio of services. This represents another example of Harmonic's commitment to enhancing our customers competitiveness with value-added services that can effectively drive subscriber retention."

Charter Deploys HD Digital Turnaround Powered by Broadcast Network Gateways

The HD digital turnaround solution accesses HD content available from either satellite or over-the-air broadcasts and then distributes this content over a cable network. A key advantage of the Harmonic gateway is the integration of multiplexing and QAM modulation functionalities in a single compact unit. The BNG protects the video quality of the source HD programming by passing through incoming HD streams.

Charter's Initial HD Markets

Charter Communications announced on May 29 that it had launched its Charter High Definition Service to the following five markets: Alhambra/Pasadena and Glendale/Burbank, California; University Park/Highland Park, Texas; Miami Beach, Florida; and Birmingham, Alabama. Charter expects to bring HD service to more areas throughout this year.

The Broadcast Network Gateway Family

Announced at the National Association of Broadcasters Conference in Las Vegas, Nevada, the BNG 6000 series is a powerful building block that can increase the functionality, flexibility and scalability of cable broadcast networks around the world. The all-in-one, single rack unit (RU) gateway serves applications requiring digital turnaround, multiplexing, modulation and upconversion. ASI or Gigabit Ethernet inputs support a wide range of architectures.
