ISO Adopts QuickTime File Format as Starting Point for
Developing Key Component of MPEG-4 Specification

Industry Leaders Collaborate on Next Generation Multimedia Standard

CUPERTINO, California--Feb. 11, 1998--Apple Computer Inc., IBM, Netscape
Corp., Oracle Corp., Silicon Graphics Inc. and Sun Microsystems Inc. today
announced that the International Standards Organization (ISO) has adopted
the companies' joint proposal to use Apple's QuickTime File Format as the
starting point for the development of a unified digital media storage
format for the MPEG-4 specification.

The six companies now look forward to collaborating with other companies
and industry bodies to further refine the specification and QuickTime file
format--ensuring that MPEG-4 quickly gains market acceptance.

"MPEG's decision to utilize the QuickTime file format for the MPEG-4
specification has huge benefits for users and the industry", said Ralph
Rogers, Principal Analyst for Multimedia at Dataquest, San Jose. "This
strategy will leverage the broad adoption of QuickTime in the professional
media space, speed the creation of MPEG-4 tools and content while providing
a common target for industry adoption."

About MPEG
MPEG-2 is the standard for entertainment quality video and audio and is the
format of choice for DVD (Digital Versatile Disc) and DVB (Digital Video
Broadcasting). MPEG-4 is an emerging digital media standard currently being
defined by ISO's Moving Picture Experts Group (MPEG) that will enable users
to select, view and manipulate audio, video and other forms of digital
content. By the adoption of the QuickTime file format as the starting point
for an MPEG-4 standard, users are assured that all digital media content
can be authored in a common file format which also supports real-time video
and audio streaming. This digital stream can then be delivered over the
Internet, corporate networks or broadcast directly into the home. By
utilizing a QuickTime-based file format, the vast majority of existing
hardware, software and digital content would work seamlessly with this
next-generation version of MPEG.

About the Proposal
The six companies' co-authored the QuickTime File Format proposal in
response to a Call For Proposals issued by MPEG based on stringent
technical examination against a broad range of requirements. The companies'
proposal recommended QuickTime's file format as the superior technology
choice because of its ability to stream across different network protocols,
its support for all forms of digital media and its extremely flexible
capabilities as a file format. Additionally, QuickTime's file format has a
strong following among creative professionals, with a wide breadth of
available development tools and cross-platform support. The QuickTime file
format is a component of the QuickTime architecture.
