 Concurrent Announces that Vivid Technology Has Been Selected by
 Comcast Cable for Video-On-Demand Technology Trial
 
 ATLANTA--(BUSINESS WIRE)--Dec. 14, 1999--Concurrent Computer Corporation (Nasdaq:CCUR - news) announced today that its wholly owned
 subsidiary, Vivid Technology, has been selected by Comcast Cable Communications, Inc. to provide the hardware and software for a Video-On-Demand (VOD)
 technology trial in a yet to be announced city, scheduled to begin in the first half of 2000.
 
 ''We are committed to the deployment of digital services. The Vivid technology platform is an excellent choice to help us test VOD services; the Vivid video server
 met our technology and network requirements,'' said Bradley P. Dusto, Executive Vice President and Chief Technology Officer of Comcast Cable Communications,
 Inc. ''We look forward to working with the Vivid team to make this VOD technology trial a success.''
 
 ''I am delighted we have been selected to provide Comcast with a fully integrated VOD system solution that will allow Comcast to run not only
 Movies-On-Demand, but additional interactive services on its installed base of digital set-top boxes,'' said Fred Allegrezza, Vivid Technology's founder.
 
 The trial will offer participating subscribers movies-on-demand, including recent Hollywood hits, classics, and other popular titles.
 
 Vivid Technology's VOD system will be deployed using the General Instrument DCT-2000 digital set-top box. Vivid's Video Server is based on a unique
 architecture of networked servers that provides scalable systems from 100 to 40,000 streams of video. The system provides a billing interface service, a
 customizable VOD subscriber interface, and the ability to include other interactive applications.
 
 Steve Nussrallah, President and Chief Operating Officer of Concurrent Computer Corporation, added, ''The industry has been waiting for a VOD trial of a General
 Instrument platform solution. I am pleased Comcast selected Vivid Technology for this landmark event.''
 
 VOD enables cable operators to offer subscribers an information and entertainment medium that provides individual freedom, control, choice, flexibility,
 convenience, and simplicity through the use of a television and a digital set-top box. The most exciting benefit of VOD technology is that it brings digital quality
 movies--including recent Hollywood hits--on-demand into cable subscribers' homes with full VCR-type control, such as pause, rewind and fast forward.
 
 For subscribers, VOD will equate to having the video rental store right in their home--minus such video store inconveniences as late fees, sold-out titles, and poor
 video quality. Furthermore, the technology allows operators to provide a revenue-generating service and an exciting, competitive offering to their subscribers.
