NAB2000

LAS VEGAS--(BUSINESS WIRE)--April 10, 2000

Harris, 4DL, NDS, Samsung and SkyStream Demonstrate

Pre-Paid MP-3 Application for DTV Using DASE Technology

Five leading technology companies--Harris Corporation, 4DL, NDS Group plc, Samsung Electronics Corporation, and SkyStream Networks-- will premier a technology that gives TV stations the opportunity to deliver new, revenue-generating pre-paid services along with free over-the-air programs on their DTV channel. The first public demonstration will take place during the National Association of Broadcasters Convention April 10-13.

The demonstration will showcase one of many possible applications of ATSC-proposed data transmission and DASE (DTV Applications Software Environment) technology--a pre-paid MP-3 music distribution service--at the Harris exhibit (Las Vegas Convention Center Booth No. L-6524).

Participating companies have brought together every component needed to deliver pre-paid services:

-    Harris Corporation has integrated the system and will demonstrate
     the MP-3 application in its NAB booth.

-    4DL has developed the interactive DASE application and provides
     the DASE authoring tool.

-    NDS has integrated its Open VideoGuard(TM) conditional access
     technology and smart card.

-    Samsung Electronics has developed the DASE Integrated Receiver
     Decoder (IRD). This IRD will be made available under the Harris
     brand name for broadcast authoring verification applications.

-    SkyStream Networks manufactures the DBN-35 source media router
     that is marketed under the Harris DATAplus(TM) brand name.
     SkyStream has worked with Harris to define the NAB demonstration
     and encapsulate the MPEG-2 transport streams.

Throughout NAB, attendees can obtain a personal smart card at four locations--the Harris exhibit, the SkyStream exhibit (Sands Booth No. I-7433), the NDS exhibit (Sands Booth No. 4138), and the 4DL exhibit (in Sun Microsystems exhibit, Sands Booth No. M-8745). The smart card, prepared by NDS, is authored with personal information and a simulated pre-paid "credit." The smart card allows its bearer to download an MP-3 file that has been encapsulated into the DTV signal by SkyStream Networks' source media routers and transmitted over the air to the Samsung DASE IRD in the Harris booth.

By inserting the smart card into the IRD, the card bearer will trigger an interactive application created by the 4DL authoring tool, enabling an MP-3 audio file to be downloaded onto a flash memory card. The Samsung IRD will automatically debit the pre-paid smart card and track the downloaded file. Downloaded MP-3 files can then be played on a Samsung Yepp MP-3 audio player.

Samsung is offering a chance to win a free Yepp MP-3 player to one person who obtains a "lucky" smart card each day of NAB. Additionally, each smart card bearer will receive a discount coupon on a Samsung Yepp, as well as other opportunities to win prizes at NAB.

A key advantage of over-the-air distribution of MP-3 digital audio is that it distributes files quickly, overcoming the lag-time problems that frequently plague consumers as they attempt to download MP-3 files distributed over the Internet. Lag-time problems are caused by the size of MP-3 files, which can require up to 4.5 mbps of bandwidth. And, because MP-3 file transfers take place live along side of video content, audio can be offered in association with such television music programs as MTV. According to a recent study by Multimedia Research Group, Inc., it is estimated that the U.S. market alone for MP-3 digital audio distribution will ultimately approach $12 billion annually.

The NAB demonstration is the first of many public demonstrations planned by the participating companies. Participating companies intend to continue to work with industry leaders and to demonstrate DASE-based applications to support proposed DTV business models.
