Six HDTV Channels Now Available to Hits Quantum Affiliates via SES Americom's AMC-18 Satellite.

Carriage Agreements Secured with 15 Cable System Operators

DENVER & PRINCETON, N.J. -- Six HDTV channels, A&E HD, HGTV HD, Food Network HD, National Geographic Channel HD, Starz HD and Universal HD, have launched on the Comcast Media Center's (CMC) HITS Quantum service aboard AMC-18, SES AMERICOM's latest HD-PRIME[TM] satellite.

HITS Quantum's HDTV service has already launched on cable systems operated by Adams Cable TV (Waymart, PA), Cablevision of Marion County (Ocala, FL) and MTC Cable (Margaretville, NY). Twelve additional cable system operators have signed up to receive the service, including Baldwin Telecom Inc., CenturyTel Televideo Inc., Eagle Communications, Merrimac Communications Ltd., Orbitel and Spencer Municipal Utilities.

HITS Quantum offers more than 200 digital video and audio services in order to support cable system operators' migration to an all-digital service. The all-digital platform, which features secured authorization, optimized DPI triggers for the insertion of ads, and high-quality video and audio, also provides networks with greater potential for additional penetration on HITS Quantum's cable systems affiliates.

In addition to using AMC-18 for carriage of the HDTV networks offered through HITS Quantum, the CMC relies on SES AMERICOM's 50-state AMC-4 satellite to deliver a high capacity service that operates at 256 QAM digital modulation. The 256 QAM lineup, which features over 50 of the widely available channels on basic and expanded basic tiers,

combines with a 64 QAM service to allow cable systems serving smaller markets to launch digital video and other advanced services at a fraction of the comparable cost for installing, operating and maintaining headend-based solutions.

"Thanks to the support of cable television programming network groups such as A&E, NBC Universal, Scripps Networks, Starz and National Geographic Channel, we are able to add HDTV to the HITS Quantum lineup, an essential component for a competitive digital video offering, as demonstrated by this initial demand from our cable MSO affiliates," said Gary Traver, COO of Comcast Media Center. "We are also very pleased to launch HITS Quantum's HD lineup on AMC-18, a key member of SES AMERICOM's HD-PRIME neighborhood."

"We are committed to keeping HD-PRIME the leading platform for HD programming, enabling cable operators to offer a wide range of premium HD networks, including Comcast Media Center's expanding HITS Quantum line-up," said Bryan McGuirk, President of Media and Enterprise Services for SES AMERICOM. "With the addition of AMC-18, the latest satellite in the HD-PRIME neighborhood, we have increased the HD programming available to operators, and have the capacity to support programmers as they create compelling, new HD channels."
