SeaChange and Imagine Broadband Partnership Focuses On Rapid Deployment of Interactive Television `
Leading Video Server Systems Provider and Broadband Integrator Co-Market, Co-Sell Products and Services

LONDON and MAYNARD, MA --Sept. 8, 2000-- Two leaders in the interactive television industry, Imagine Broadband and SeaChange International, Inc., are combining their strengths to enable more television companies to speed the launch of services such as video-on-demand (VOD) to consumers. The companies have agreed to co-market their products and services and collaborate in product engineering, integration and system deployments.

SeaChange International, Inc. (Nasdaq:SEAC) is the world leader in deployments of digital video systems, including video servers, automation software and content management, for advanced television services. A pioneering enabler of such services, Imagine Broadband focuses on software and systems engineering and integration. With its fundamental adherence to open standards and open application interfaces that encourage third-party development of value-added products, SeaChange complements Imagine Broadband's expertise in the integration of the wide array of today's digital cable products and interactive technologies.

The relationship between Imagine Broadband and SeaChange has its genesis in one of the first commercial deployments of video-on-demand in Europe - Telewest Communications in London, where thousands of cable subscribers have access to hit movies streamed from cable headends. Building upon this initial success, the companies are already collaborating on a number of other interactive television deployments.

"Cable companies have increasingly called on SeaChange and Imagine Broadband independently to enable their interactive strategies," said Bill Styslinger, president and CEO, SeaChange International. "Now with the resources afforded by our collaboration with such partners, we act on the business much faster, right from the initial exploration of new opportunities, to ensure the quality and speed of installations and the long-term success of customers."

"We pride ourselves on excellence and on being at the leading edge of development," said Imagine Broadband's CEO, Dr. Arjang Zadeh, who led the world's first ever team to deliver commercial broadband interactive digital television over a cable platform. "Imagine Broadband's world leading system integration team have the capability to get interactive services off the ground in an risk-managed and cost-effective manner. This skill set leveraged with SeaChange's innovative interactive television systems enables our clients to maintain their leadership in the broadband industry."

Installed in cable television operations around the world, SeaChange's ITV System is a distributed software-based platform that leverages the patented MediaCluster technology to enable unprecedented video storage and streaming capacity. MediaCluster enables a single file copy of a video asset - movie, commercial, TV program - to support thousands of simultaneous requests. Operational efficiency is maintained by Command Center software, which manages the lifecycle of video assets, monitors total system performance and leverages MediaCluster to meet the requirements of large-scale interactive television services.

Representatives of both companies will be available at IBC 2000 in Amsterdam, stand 8.180.
