LAS VEGAS, NV -- (MARKET WIRE) -- May 7, 2007 --The Cable Show '07 -- Scientific Atlanta, a Cisco (NASDAQ: CSCO) company, today announced the addition of the OpenCable™ Application Platform (OCAP™) developer program, expanding the company's relationship with iTV services provider itaas. As the industry evolves and OCAP capabilities continue to be adopted and executed, Scientific Atlanta is taking advantage of itaas' istart Developer Program -- enabling application developers to build OCAP applications more easily and efficiently using Scientific Atlanta's complete, end-to-end OCAP platform.

Similar to the istart SARA (Scientific Atlanta Resident Application) and InView™ developer programs, the istart OCAP developer program will help maximize OCAP development efficiencies by reducing market entry costs, speeding time-to-market and springboarding further innovative application development.

"OCAP represents a prime opportunity for the escalating growth of advanced digital TV services," said Jeff Seebeck, vice president, product strategy and development for Subscriber Networks, Scientific Atlanta. "One of the ways Scientific Atlanta is committed to helping operators take advantage of these opportunities is by establishing a standard platform and developing technologies that seamlessly bridge multiple applications across multiple devices.

We are excited about this opportunity that further strengthens our relationship with Scientific Atlanta and supports our mission to expand iTV applications in the industry."
