ANTEX ELECTRONICS INKS DEAL WITH DMX MUSIC FOR NEXT-GENERATION AUDIO-VIDEO DELIVERY SYSTEM

"DMX Axis" Incorporates Technologies from Antex, IBM and Microsoft

Las Vegas, NAB - LVCC, Booth # R-687. (April 10, 2000) -- Antex Electronics, the leading manufacturer of high-end digital audio equipment for the professional audio, video and broadcast markets, today announced an agreement in excess of $2 million with DMX MUSIC, a wholly-owned subsidiary of Liberty Digital, Inc., in which Antex will develop and manufacture for DMX MUSIC the client hardware of a groundbreaking multimedia delivery system designed for the commercial marketplace.

Using advanced software technology from IBM and Microsoft, the initial contract calls for Antex to provide and integrate its client hardware to "DMX Axis." DMX Axis is a multimedia system combining hardware, software and the Internet to deploy and manage the delivery of audio and video content in an entirely new way.

DMX Axis is optimized for the retail industry, allowing stores of virtually any size the ability to affordably personalize their music strategy to specifically cater to their own individual personality and demographics – complementing the ambiance they wish to create.

"The combination of our deep and constantly growing music library with Antex’s proven track record for the highest quality of hardware manufacturing for digital music applications is a powerful collaboration that will redefine the shopping experience, both for the retailer and consumer," said Lon Troxel, CEO and president of DMX MUSIC.

DMX Axis blends the Internet’s proven ability for delivering data quickly and cost-effectively with DMX MUSIC’s digital music library, one of the largest in the world. The Axis system comes pre-loaded with hundreds of hours of music. The plug-and-play receiver resides in the store, while music titles and playlists are automatically deployed to it (and updated) via an Internet connection.

"We’re very excited to be building on our already phenomenal relationship with DMX MUSIC," said Jim Antrim, president and CEO of Antex. "DMX Axis represents a very compelling development not only for our company, but for the whole industry. It’s the first system of its kind in the world to use the advanced audio compression features of Windows CE in a desktop appliance, and we’re confident end users will embrace it enthusiastically for its power and flexibility to reach customers in a more personal way."

A critical part of Axis is its use of IBM’s Digital Media Distributor (DMD), an automated system that enables geographically dispersed organizations to centrally manage, customize and distribute digital content to numerous remote locations. DMD consists of two components – the Central Site, which manages the distribution of digital content, and the Remote Site, which receives the content and plays it back.

With the DMD platform, part of IBM’s media asset management architecture, the Axis subscriber terminal can provide digital messaging, video and dynamic point-of-sale and in-store merchandising – in addition to its core function of digital music delivery.

Antex began development of the client hardware for DMX Axis in November 1999, which is being designed and built at Antex’s location in Gardena, CA – the only ISO-9001-certified facility in its industry.
