   [8]http://www.w3.org/ -- 9 August 2001 -- The World Wide Web
   Consortium ([9]W3C) today released the [10]SMIL (Synchronized
   Multimedia Integration Language) 2.0 specification as a W3C
   Recommendation, representing cross-industry agreement on an XML-based
   language that allows authors to write interactive multimedia
   presentations. A W3C Recommendation indicates that a specification is
   stable, contributes to Web interoperability, and has been reviewed by
   the W3C Membership, who favor its adoption by the industry.

  SMIL 2.0 Uses XML to Deliver Synchronized Multimedia to the Web

   Web authors are in search of ways to deliver rich content, including
   video, audio, and text, and to synchronize those components as they
   see fit. It's no longer simply television on the Web that end users
   are seeking; people are looking for information and experiences that
   take full advantage of the Web's technical capabilities -
   interoperability, flexibility, device choice, and searchability.

   "SMIL 2.0 enables authors to bring rich content to the Web in a
   that is easily written and reused," explained Tim Berners-Lee, W3C
   Director. "SMIL 2.0 avoids the limitations of traditional television
   and lowers the bandwidth requirements for delivering multimedia
   content over the Internet."

   With SMIL 2.0, producing reusable audio-visual presentations is easy;
   as SMIL 2.0 is an [11]XML application, one may use a simple text
   editor to create engaging multimedia experiences for the Web. SMIL
   allows the author to incorporate a wide range of data (audio, video,
   or text), which may be locally or remotely stored.

  SMIL 2.0 Built and Tested with Developers, Users in Mind

   [12]SMIL 1.0, produced by W3C in 1998, brought powerful XML based
   multimedia presentations to the Web, and content developers began
   on presentations, authoring tools and players. As a result, the W3C
   [13]Synchronized Multimedia (SYMM) Working Group received suggestions
   and requests from developers on new features they would like to see.
   Over 600 test cases were developed to ensure that SMIL 2.0 would meet
   the needs of developers for new features and interoperability with
   SMIL 1.0.

  SMIL 2.0 Brings Greater Authoring Flexibility

   SMIL 2.0 has been produced as a set of modules which, individually or
   in combinations, may meet the needs of a Web author, and build on the
   guiding principles of interoperability at the core of W3C work. In
   addition to full incorporation of the successful SMIL 1.0 features,
   SMIL 2.0 Modules provide functionalities including animation; content
   control; layout; linking; media objects; metainformation; structure;
   timing and synchronization; time manipulations; and transition
   effects. This gives authors the ability to create sophisticated
   animation, event-based interaction with a presentation, and graceful
   transition effects based on nearly 100 predefined options.

  SMIL 2.0 Profiles Work with Diverse Devices

   By combining individual modules together, the W3C SYMM Working Group
   defines two SMIL 2.0 profiles. Profiling introduces the ability to
   tailor an XML-based language to specific needs, e.g. to optimize
   presentation and interaction for the client's capabilities. One
   profile is for comprehensive SMIL 2.0 presentations, and another
   suited to handheld/mobile devices, called SMIL Basic. This gives
   authors the ability to create presentations which are adaptable to
   different environments, whether limitations are due to bandwidth or

   Profiling also adds the ability for integrating functionality from
   other markup languages. The work done to combine [14]Scalable Vector
   Graphics (SVG) with SMIL 2.0 Modules has proven successful, and the
   early work with combining [15]XHTML modules is promising.

  SMIL 2.0 Makes Searchable and Accessible Multimedia Possible

   Multimedia presentations can sometimes be a bit of a black box to
   those searching for information on the Web. Because a SMIL
   presentation is written as a text file, it can include [16]metadata
   components, which make a SMIL presentation searchable.

     [16] http://web3.w3.org/Metadata/RDF/

   The SYMM Working Group worked closely with W3C's [17]Web
   Initiative to develop a format that supported accessible media.
   [18]Accessibility Features of SMIL are described in a separate
   document, and show how authors and software developers may create
   presentations and software that make SMIL work for the widest

  International Cross-Industry Participation Key to SMIL 2.0 Development

   The SMIL 2.0 specification was written and developed by the SYMM
   Working Group, a unique mix of experts from many divergent industries
   - CD-ROM manufacturers, Interactive Television, Web, Mobile
   Communications, and audio/video streaming - all interested in
   synchronized multimedia to the Web. The W3C SYMM Working Group is
   comprised of key industry players including Glocomm, IBM, Intel,
   Macromedia, Microsoft, Netscape/AOL, Nokia, Oratrix, Panasonic,
   Philips, RealNetworks and WGBH; as well as research and government
   organizations such as CWI (Centre for Mathematics and Computer
   Science, the Netherlands), INRIA (Institut National De Recherce en
   Informatique et en Automatique, France), and NIST (National Institute
   of Standards and Technology, USA). Manufacturers of both SMIL Players
   and SMIL authoring tools are committed to supporting SMIL 2.0, as
   evidenced in their [19]testimonials.

About the World Wide Web Consortium [W3C]

   The W3C was created to lead the Web to its full potential by
   developing common protocols that promote its evolution and ensure its
   interoperability. It is an international industry consortium jointly
   run by the [20]MIT Laboratory for Computer Science (MIT LCS) in the
   USA, the [21]National Institute for Research in Computer Science and
   Control (INRIA) in France and [22]Keio University in Japan. Services
   provided by the Consortium include: a repository of information about
   the World Wide Web for developers and users, and various prototype
   sample applications to demonstrate use of new technology. To date,
   over 520 organizations are [23]Members of the Consortium. For more
