    LinuxWorld, NEW YORK, Jan. 22 /PRNewswire-FirstCall/ --
 RealNetworks(R), Inc. (Nasdaq:   RNWK), the global leader in Internet media
 delivery, (Booth #363), today announced the third source code component of the
 Helix(TM) platform, the Helix DNA Server, is now available to software
 developers through the Helix Community at www.helixcommunity.org.  With Helix
 DNA Server, developers for the first time have source code access to a major
 end-to-end media delivery platform, consisting of producer, server and client
 components.  Helix DNA Server is the core source code of RealNetworks' Helix
 Universal Server, the 9th generation, multi-format digital media server that
 thousands of webcasters already use to deliver content on the Internet.
     RealNetworks also announced that more than 10,000 software developers have
 joined the Helix Community since its launch in July, and that the Open Source
 Initiative (OSI) has certified the public source license used by the Helix
 Community.
     "Today we deliver on the commitment we made in July to create a complete,
 open media delivery platform and source code community," said Rob Glaser,
 founder and CEO, RealNetworks, Inc.  "With 10,000 members and proven
 foundational technology, the Helix Community is ready to take flight!"
     Helix DNA Server source code will enable developers to build multi-format
 products for live and on-demand streaming, web collaboration, mobile media
 delivery, in-home streaming, and many other applications.  Helix DNA Server
 streams MP3, RealAudio(R) and RealVideo(R).  RealNetworks intends to add
 support for MPEG-4 after the MPEG-4 systems license terms have been released
 by the MPEG-4 licensing body, MPEG LA.  Developers can create extensions for
 other media types such as Windows Media and QuickTime, or they can license
 these extensions from RealNetworks through the Helix Community.  The Helix DNA
 Server is available for AIX, HP-UX, Tru64, FreeBSD, Linux, Solaris, Windows NT
 and Windows 2000 operating systems.
     Video testimonials supporting the Helix DNA Server from Cisco, HP, and Red
 Hat are available at www.helixcommunity.org
     Helix DNA Server is the third release of source code into the Helix
 Community.  In October, RealNetworks released the Helix DNA Client source
 code, which enables developers to build playback applications that support any
 format.  In December, RealNetworks released the Helix DNA Producer, which
 enabled developers to build encoding applications that support any format.
 The Helix platform has already received wide industry support from the likes
 of Cisco, HP, IBM, Network Appliance, nCUBE, Nokia, Oracle, PalmSource,
 Pinnacle Systems, Red Hat, Sun Microsystems, Symbian, Virage, Volera and many
 others.
