{{quotation | 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.}} ([http://www.w3.org/AudioVideo/ Synchronized Multimedia] (W3C) retrieved 18:11, 20 March 2007 (MET)).


== Versions and features ==

SMIL is an extensible standard. That means that providers can expand SMIL with their own [[XML namespace]]d extensions. E.g. QuickTime does so.

=== SMIL 1 ===

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

# describe the temporal behavior of the presentation
# describe the layout of the presentation on a screen 
# associate hyperlinks with media objects 

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

=== SMIL 2 ===

Features of SMIL 2:
# Timing: 
#* AccessKeyTiming
#* BasicInlineTiming
#* BasicTimeContainers
#* EventTiming
#* ExclTimeContainers
#* FillDefault
#* MediaMarkerTiming
#* MinMaxTiming
#* MultiArcTiming
#* RepeatTiming

#* RestartDefault

=== SMIL 3 ===

Ssince dec. 2008, SMIL 3.0 is a W3C recommendation. {{quotation|It is built on top of SMIL 2.1. A large number of SMIL 2.1 Modules [SMIL21-modules] remain the same in SMIL 3.0. SMIL 3.0 introduces new SMIL 3.0 Modules with extended functionalities.}} ([http://www.w3.org/TR/SMIL3/smil-introduction.html#introNS-Relationsmil20 Relation to SMIL 2.1], retrieved 18:16, 4 September 2009 (UTC)).

=== SMIL profiles in other W3C languages ===

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]]. Not all of these SMIL 2 modules are integrated into the XHTML+SMIL profile or the [[SVG]] standard. In addition, one has to
understand ''how'' they are integrated, i.e. what kinds of HTML/SVG elements can be
animated in which ways.

== Implementations ==

[[User:Daniel K. Schneider|Daniel K. Schneider]] believes that '''all''' browsers should have implemented XTHML+SMIL and full [[SVG]] (i.e. static SVG / DOM interactivity and animation/[http://www.w3.org/TR/SVG11/animate.html SMILE animation])  '''years ago''' but it didn't happen that fast.

SVG, finally, is now part of [[HTML5]] and as of April 2012, and SVG-SMIL tags work in most browsers (except IE9). HTML5 does not implement HTML+SMIL.

=== Native Web browser implementations ===

;Microsoft HTML + TIME

{{quotation | HTML+TIME (Timed Interactive Multimedia Extensions), first released in Microsoft Internet Explorer 5, adds timing and media synchronization support to HTML pages. Using a few Extensible Markup Language (XML)-based elements and attributes, you can add images, video, and sounds to an HTML page, and synchronize them with HTML text elements over a specified amount of time. In short, you can use HTML+TIME technology to quickly create multimedia-rich, interactive presentations, easily and with little or no scripting. }} ([http://msdn2.microsoft.com/en-us/library/ms533099.aspx, retrieved 15:09, 4 May 2007 (MEST)])

{{quotation|HTML+TIME 2.0 is based on the HTML+SMIL language profile World Wide Web link in the Synchronized Multimedia Integration Language (SMIL) 2.0 World Wide Web link working draft. SMIL 2.0 is the W3C successor to SMIL 1.0. HTML+TIME 2.0 is the successor to HTML+TIME 1.0.}}([http://msdn2.microsoft.com/en-us/library/ms533099.aspx, retrieved 15:09, 4 May 2007 (MEST)])

Starting IE 5.5. the Microsoft ''HTML+TIME'' implementation is quite conformant to the W3C XHTML+SMILE profile, but as far as we understand a bit different. In addition,
[[User:Daniel K. Schneider|Daniel K. Schneider]] wonders why they have to stick to this name, instead of calling it HTML+SMILE.

; Firefox, Safari, Chrome and Opera

As of Winter 2012, SMIL is now implemented within SVG and HTML5/SVG (since SVG is now part of HTML). XHTML+SMIL is not.

=== Media players ===

[[Media player]] is a term typically used to describe computer software for playing back multimedia files. Most software media players support an array of media formats, including both audio and video files.
