SCIENTIFIC-ATLANTA BEGINS DELIVERY OF DS-3 INTERFACE FOR TRANSMISSION OF DIGITALLY COMPRESSED VIDEO OVER FIBER LINES

 Provides Option to Traditional Satellite Delivery of Cable TV
 Programming and New Business Opportunity for Telcos to Carry
 Programming and Interactive Services
 ATLANTA, June 1 /PRNewswire/ -- Scientific-Atlanta, Inc. (NYSE: SFA) has delivered the first of its new Model D9700 DS-3 interface which provides an option for the entertainment industry to deliver programming to cable headends over fiber circuits and new business opportunities for telephone companies and alternative carriers.
 The DS-3 interface allows up to 20 compressed video signals to be carried over a standard DS-3 (45 Megabits per second) telecommunications circuit.
 Vyvx and IDB Communications Group have received the first Model D9700 DS-3 production units, as part of a Scientific-Atlanta digital video compression system, for delivery of sports highlight feeds over digital fiber to major TV broadcast and cable networks and TV stations nationwide.
 "Program providers now have another alternative to satellite delivery of programming and other services to the headend," said Ronald Foster, vice president and general manager of the telecom products division of Scientific-Atlanta's Broadband Communications Group, which is supplying the DS-3 interface. Scientific-Atlanta's digital video compression system has been operating over satellite. Viacom International, Inc. and StarNet Inc. have installed Scientific-Atlanta compression systems for the entertainment and cable TV ad insertion markets respectively.
 "This understanding of the interfaces for both satellite and fiber and how they relate in a broadband communications delivery system is vital to the development of an electronic superhighway," Foster said. "The new DS-3 interface adds the ability to carry video program material and interactive services over the extensive digital fiber networks of telephone companies and alternative carriers," Foster said.
 Scientific-Atlanta recently demonstrated four studio quality, CCIR-601 compliant digital video signals over a DS-3 fiber circuit at the Supercomm Show in Atlanta. Four live satellite signals were encoded in real time at a site 20 miles north of Atlanta and delivered to the show floor via a Southern Bell provided DS-3 circuit.
 Scientific-Atlanta, Inc. is a world leader in broadband communications systems, cable television electronics, satellite-based communications networks, and instrumentation for industrial, telecommunications and government applications.
