Scientific Atlanta's New-Generation IP Statistical Multiplexing to Simplify Creation of New and Expanded Programming Bouquets

LAS VEGAS, NV and ATLANTA, GA -- (MARKET WIRE) -- April 17, 2007 -- Scientific Atlanta, a Cisco (NASDAQ: CSCO) company, today announced a new-generation IP-based statistical multiplexing (stat mux) technology at NAB 2007 in Las Vegas. This innovative Internet Protocol (IP)-based technology has been designed to support high-quality, low-bit-rate, bandwidth-saving video delivery and provide breakthrough performance for creating or expanding channel bouquets.

Designed for a variety of applications, including digital terrestrial, cable headends, satellite direct to home and satellite distribution, the Scientific Atlanta® IP (Internet Protocol) stat mux solution will use software and IP interfaces to help control the video encoders. This capability, combined with the multiplexing and video processing power of Scientific Atlanta's sophisticated Digital Content Manager, will significantly enhance flexibility as operators introduce new channels and package these into new or expanded bouquets.

Control of multiple program bouquets from one location can help operators and content owners easily reconfigure local and remote encoders to rapidly add content in response to customer demands for more varied channel offerings. The capability to reconfigure remotely located encoders within the same statistical multiplexing pool helps eliminate the need for a dedicated contribution link.

The versatile Scientific Atlanta innovation can support mixed stat muxes that include both MPEG-2 standard definition (SD) and MPEG-4 high definition (HD) signals or programming bouquets that include both MPEG-4 SD and MEGP-4 HD signals. This mixed stat mux technology helps support a smooth transition from MPEG-2 to MPEG-4 encoding, as well as the migration to increased HD programming availability.

"This new-generation statistical multiplexing technology can offer operators a flexible platform that can support a greatly expanded number of encoders within multiple virtual pools, all managed from a single controller," said Dean Rockwell, vice president Digital Media Networks at Scientific Atlanta. "This performance significantly outpaces existing stat mux technology and helps continue the industry-wide migration toward IP-based network solutions being championed by Cisco and Scientific Atlanta."

The Scientific Atlanta solution is designed to provide outstanding scalability supporting more than 60 encoders within up to 20 different statistical multiplexing pools from just one controller. The controller can be integrated within the DCM as a software option or run independently on the encoders depending on the encoder type and configuration.

The exceptional IP stat mux technology will be demonstrated at NAB 2007 in Las Vegas, April 16-19.
