Louisville, Colorado, January 22, 1998—Cable Television Laboratories, Inc. (CableLabs®) has contracted with Scientific-Atlanta to assist the OpenCable™ project in key areas regarding the system integration of new OpenCable™ devices and services. This work will help ensure that the individual interfaces specified by the OpenCable™ project will support an integrated network and set of services.

Scientific-Atlanta will focus on the end-to-end system integration of new digital services on the cable industry's networks. Under its contract with CableLabs, Scientific-Atlanta will produce and document a network architecture reference model. It will identify scenarios for customer use, billing, and third-party applications that will involve important OpenCable™ events and data flows. Scientific-Atlanta will also help define key system/network interfaces, with special emphasis on the physical and communication layer interfaces.

OpenCable™ is a cable industry initiative which seeks to obtain and deploy a family of interoperable advanced digital set-top boxes from various manufacturers. OpenCable™ seeks to achieve specifications for an open architecture that will allow multiple operating systems and microprocessors to be employed. CableLabs is managing the OpenCable™ specification writing process on behalf of its cable operator members.

"Scientific-Atlanta will be a great help to our fast-track project," said William Schleyer, head of the CableLabs OpenCable™ Task Force. "Their knowledge of cable's advanced digital environment and their experience in working with advanced technology deployments were critical points in our selection," Schleyer said.

"The work that Scientific-Atlanta will undertake will benefit all vendors in the OpenCable™ process," said Dr. Richard R. Green, CableLabs president and CEO. "This is an important step toward an open architecture."

It is anticipated that Scientific-Atlanta will complete its work in the first quarter of 1998, thereby allowing mid-year completion of the OpenCable™ specification.

"Scientific-Atlanta is committed to helping the cable television industry meet its aggressive timelines on OpenCable™," said James F. McDonald, President and CEO of Scientific-Atlanta. "I believe that this contract in this high priority area indicates the level of confidence the cable industry has in our experience and expertise in designing and deploying two-way interactive networks," he added.
