Gigabit Ethernet Solution Lowers Video Transport Costs

nCUBE Corporation and Harmonic Inc. (Nasdaq:HLIT), today announced that Charter Communications, Inc. (Nasdaq:CHTR), has installed the two companies' end-to-end Gigabit Ethernet solution for video-on-demand (VOD).

Gigabit Ethernet is a transport vehicle that allows cable operators to deliver a wide range of video services to customers with dramatically reduced transport costs. The technology gives operators the flexibility to easily add new on-demand services to existing systems and save overhead costs on decentralized server technology over existing networks.

"Gigabit Ethernet technology will help Charter make the most out of our investment in nCUBE and Harmonic's VOD equipment," said John Pietri, Charter's senior vice president of Engineering. "We welcome this type of innovation, especially when it allows us to optimize our capital investment coupled with a smarter way to serve our customers."

"Charter continues to play a leading role in the implementation of cutting-edge technology, offering best-of-class digital services to television viewers," said Michael Pohl, president and chief executive officer, nCUBE Corporation. "As the roll out of new services such as VOD continues, nCUBE and Harmonic have developed a powerful solution that provides cable operators the technology and business tools to lower the overall cost of delivering advanced on-demand services and to maximize revenue potential. nCUBE's platform supports the technology of today and tomorrow's world of everything-on-demand."

nCUBE's on-demand suite provides operators a complete solution for delivering the on-demand services of today with the scalability to support on-demand television's future, everything-on-demand (EOD). nCUBE's n4 and enhanced n4x On-Demand Servers utilize a hypercube interconnect server architecture that can allow 53,000 users the ability to simultaneously access the same piece of content, and provides more than 200,000 hours of unique content storage. The nABLE On-Demand Management System is the industry's most comprehensive and automated back-office system for managing on-demand services. nODA offers operators the ability to customize and brand their VOD and subscription VOD (SVOD) services to create a unique and compelling user experience.

"Charter's deployment of video-on-demand services using Gigabit Ethernet underscores their broad vision and foresight in bringing compelling interactive services to market," said Dr. Yaron Simler, president of Harmonic's Convergent Systems Division. "The combination of the nCUBE server and Harmonic content-on-demand delivery systems enables Charter, and other cable operators, to more efficiently transport and distribute VOD streams as well as increase their revenue potential by more easily expanding their capacity, reach and range of services."

Harmonic's open standards-based content-on-demand transport and distribution systems provide greater scalability and flexibility as well as interoperability with the wide array of equipment -- including video servers, conditional access systems, transport protocols and set-top boxes -- found in today's networks. Harmonic's VOD solutions, which fit seamlessly into virtually any cable environment, enable operators to more easily adapt their networks to deliver content-on-demand services while introducing the superior economics and capacity of Gigabit Ethernet (GbE) transport. Harmonic's Narrowcast Services Gateway(TM) (NSG), a key element of the solution, processes streams from multiple high capacity servers in addition to performing multiplexing, program filtering and routing. The NSG features four dual integrated QAM RF outputs or multiple ASI output interfaces.
