—Nation's Leading Remote Television Services Provider to Install $270K of Grass Valley HD Distribution Amplifiers—

NEVADA CITY, Calif., Aug. 19, 1999 — National Mobile Television, the nation's leading provider of remote television services, extended its digital technology leadership with $270,000 of Grass Valley™ high-definition distribution amplifiers. The distribution amplifiers are currently being installed into National Mobile Television's three high-definition remote mobile units. They will be used to distribute high-definition serial component digital video signals for coverage of a variety of sporting and entertainment events such as Major League Baseball, NBA Basketball, NFL Football, NHL Hockey, and concert tours.

"The M9603HD distribution amplifier is the perfect choice for the transition from 601 digital to the new HD world. With the internal down converter we are able to continue to use current technology along with the new HD products. Thank you Grass Valley Group," said Mark Brooks, vice president of engineering, National Mobile Television.

"Grass Valley has 40 years of experience in providing leading-edge distribution products. Our first distribution amplifier was designed specifically for ABC's coverage of the 1964 Democratic Convention. Since then, our distribution amplifier product line has grown to cover just about every conceivable type of distribution amplifier available. Grass Valley distribution amplifiers are the smart choice for reliable signal distribution," said Tim Thorsteinson, president and chief operating officer, Grass Valley Group.

National Mobile Television purchased the M9603HD Monitoring distribution amplifiers, part of the award-winning M9600 HDTV product line. Designed to extend the life of a standard resolution monitor, the M9603HD allows HDTV signals to be monitored using either NTSC or serial digital input (SDI) on standard definition monitors. Its intended application is to verify signal presence and monitor video content in on-air, production and post-production environments. The M9603HD provides four 1.5 Gbps outputs for HDTV distribution and two NTSC and two serial component digital outputs for low-cost standard definition monitoring.
