SMIL

Draft

“The Synchronized Multimedia Integration Language (SMIL, pronounced "smile") enables simple authoring of interactive audiovisual presentations. SMIL is typically used for "rich media"/multimedia presentations which integrate streaming audio and video with images, text or any other media type. SMIL is an easy-to-learn HTML-like language, and many SMIL presentations are written using a simple text-editor.” (Synchronized Multimedia (W3C) retrieved 18:11, 20 March 2007 (MET)).

Features

SMIL 1 allows integrating a set of independent multimedia objects into a synchronized multimedia presentation. Using SMIL, an author can

1. describe the temporal behavior of the presentation
2. describe the layout of the presentation on a screen
3. associate hyperlinks with media objects

• These together can be used to produce "true" multimedia animation

SMIL syntax and semantics can be used in other XML-based languages, in particular those who need to represent timing and synchronization. For example, SMIL 2.1 components are used for integrating timing into XHTML and into SVG.
