 ICT(R) Orders Same Dolby Encoder Technology Selected
 by HDTV Grand Alliance and GI's DigiCable
 SAN FRANCISCO, Jan. 17 /PRNewswire/ -- Following the selection of the AC-3 multichannel audio technology by the U.S. High Definition Television (HDTV) Grand Alliance and General Instrument's DigiCable compressed video system, Dolby Laboratories has announced that International Cablecasting Technologies Inc. (ICT) (NASDAQ-NMS: TUNE) will become the first commercial DBS user of the DP521 Dolby hardware for the company's new DBS audio service.
 San Francisco-based Dolby said they have made the first shipment of stereo AC-3 encoders, to be used with the company's new DMX for Business, direct broadcast satellite (DBS) system.
 First employed in the digital film sound format, Dolby Digital AC-3 was recently chosen as the audio format for future U.S. HDTV systems. The AC-3 process can encode up to six separate audio channels, all in less than half the space required for a single channel on a CD.(+)
 "The stereo version of AC-3 gives us the opportunity to provide up to 120 DBS channels of stereo audio on a single transponder while maintaining CD quality," said Jerry Rubinstein, ICT's chairman and chief executive officer.
 "It also gives us audio compatibility with emerging video cable compression technology and dovetails nicely with our existing Scientific-Atlanta cable delivery system by providing more DMX music at the headend."
 Satellite transmission testing of the DMX DBS service will begin in February, with the commercial rollout scheduled for June.
 "The DP521 encoder selected by ICT is the first in a family of AC-3 systems for the broadcast, cable and telecommunications markets," commented Dick Bell, general manager of the Dolby Communications Products Group. "The combination of high audio quality and spectral efficiency that AC-3 provides will dramatically expand the market for perceptual coding technology."
 Bell added that, significantly, stereo AC-3 will allow manufacturers and service providers in the cable and satellite arenas to prepare for the multichannel world of the future. "Stereo decoders can be designed," he explained, "so that they readily adapt to the multichannel data stream available from both HDTV broadcasts and new cable consumer delivery formats."
 San Diego-based ComStream will be supplying satellite receivers with built-in AC-3 decoders for the new DMX DBS programming service. The 120-channel receiver will accept signals from a mid-power, KU-band transponder utilizing a small 29-inch antenna dish.
 "We're proud of this technological achievement," noted John Puetz, ComStream's director of marketing for Audio Broadcast Products. "It's a testament to our technical and engineering staff expertise and their ability to meet and conquer the growing demands and challenges facing the telecommunications industry today."
 Launched in early 1992, DMX for Business currently offers 30 channels of uninterrupted, commercial-free, CD-quality stereo music programming delivered via cable to businesses and commercial establishments.
 Publicly traded on NASDAQ/NMS (TUNE), ICT is backed by some of the cable industry's leading players, including Telecommunications Inc. (TCI), Scientific-Atlanta Inc., Viacom, KBLCOM, Colony Communications, Crown Media Inc. and Shaw Communications Inc. of Canada.
 ComStream, a major international provider of satellite-based communications systems and networks for voice, data, imaging and video applications, is a division of Spar Aerospace Ltd. Spar is a publicly owned Canadian company engaged in the design, development, manufacturing and servicing of systems and products for space, robotics, communications, remote sensing, electro-optics and aviation markets.
