<p class="intro">Next generation browsers will treat audio and video as easy as
old browsers treated text and images.</p>
<hr />
<h2>HTML+TIME</h2>
<p>In the previous chapter you saw Internet Explorer could display SMIL elements in HTML.</p>
<p>The history behind this is shortly as follows:</p>
<p>In June 1998
SMIL 1.0 became a W3C Recommendation.</p>
<p>In September 1998 Microsoft, Macromedia, Compaq/Digital and Digital
Renaissance submitted HTML+TIME to W3C as a
proposal for adding SMIL 1.0 timing and synchronization support to HTML.</p>
<p>The HTML+TIME document describes very much the support for SMIL that can be
found in Internet Explorer 5.</p>
<hr />
<h2>XHTML+SMIL</h2>
<p>In August 2001 SMIL 2.0 became a W3C Recommendation, and XHTML+SMIL became a separate Working Draft,
based on the ideas in the HTML+TIME note.</p>
<p>The XHTML+SMIL document describes very much the support for SMIL that can be
found in Internet Explorer 6.0.</p>
<p>You can read more about the SMIL activities at W3C at
<a href="../w3c/default.asp">our W3C Tutorial</a>.</p>
<hr />
<h2>What Is Happening Here?</h2>
<p>SMIL is currently in a very interesting development process.</p>
<p>SMIL 1.0 defined a simple way to create visual media presentations and how to
play them.</p>
<p>HTML+TIME added SMIL 1.0 abilities to nearly all HTML elements.</p>
<p>SMIL 2.0 added interactivity and transitions to SMIL 1.0.</p>
<p>XHTML+SMIL adds SMIL 2.0 abilities to nearly all XHTML elements.</p>
<p>XHTML+SMIL has a great potential for taking the web to the next level, and
let browsers treat audio and video like "old" HTML treated text and images. Many
of these features are already implemented in Internet Explorer. </p>
<hr />
<h2>Why XHTML+SMIL?</h2>
<p>Is it not obvious?</p>
<p>To run a SMIL presentation you need a SMIL player. If you want your audience
to see your presentation, your audience will have to install a SMIL player.
Would it not be nicer if your audience could display your presentation in their
Internet browser?</p>
<p>SMIL defines a set of multimedia elements. Each of these elements can be
given layout, timing, and transition attributes and rules. Would it not be nicer
if you could add these attributes and rules to all your HTML elements? </p>
<p>At W3Schools we have created a number of examples that anyone with a simple text
editor, can refine to communicate their ideas as effectively as a television
commercial. Please go ahead and play with them.</p>
