The SMIL Animation was written by the SYMM Working Group, a member of W3C Interaction Domain, in cooperation with the SVG Working Group, a member of W3C Document Formats domain.
The more mathematical but precise definition of animation says that it is a time-based manipulation of a target element (or the manipulation of any attribute of the target element). It’s simply a mapping in time of the different states of the object. This type of mapping is valid for any aspect of timing, as well as animation-specific semantics.
The
SMIL 2.0, the Synchronized Multimedia Integration Language, has begun to establish itself as an important new approach for integrating multimedia into Web content. SMIL, which offers XML-based approaches for controlling the timing and presentation of multimedia elements, has begun to attract the support of many large software vendors and toolmakers, making it increasingly accessible for developers. In this article, Anne Zieger provides an overview of SMIL and describes several tools available to make SMIL coding simpler.
For developers outside the
This document specifies the second version of the Synchronized Multimedia Integration Language (SMIL, pronounced "smile"). SMIL 2.0 has the following two design goals:
* Define an XML-based language that allows authors to write interactive multimedia presentations. Using SMIL 2.0, an author can describe the temporal behavior of a multimedia presentation, associate hyperlinks with media objects and describe the layout of the presentation on a screen.
* Allow reusing of SMIL syntax and semantics in other XML-based languages, in particular those who
Synchronized Multimedia Integration Language 2.0 (SMIL 2.0) is an XML-based language that allows authors to describe the temporal behavior of a multimedia presentation, associate hyperlinks with media objects and describe the layout of the presentation on a screen.
Rather than being formulated as a standalone multimedia vocabulary (like SMIL 1.0), SMIL 2.0 syntax and semantics may be reused in other XML-based languages, as when SMIL components are used for integrating timing into eXstensible HyperText Markup Language (XHTML) or Scalable Vector
This document specifies the third version of the Synchronized Multimedia Integration Language (SMIL, pronounced "smile"). SMIL 3.0 has the following design goals:
* Define an XML-based language that allows authors to write interactive multimedia presentations. Using SMIL, an author can describe the temporal behaviour of a multimedia presentation, associate hyperlinks with media objects and describe the layout of the presentation on a screen.
* Allow reusing of SMIL syntax and semantics in other XML-based languages, in particular those who need to
W3C has published a First Public Working Draft for Timed Text (TT) Authoring Format 1.0 — Distribution Format Exchange Profile (DFXP). The draft has been produced by members of the Timed Text (TT) Working Group as part of the W3C Synchronized Multimedia Activity.
The W3C Timed Text Working Group was chartered in January 2003 to "develop an XML-based format used for the representation of streamed text synchronized with other timed media, like audio and video. A typical application is real time captioning of movies on the Web (e.g., integrated in
Abstract
This document specifies the distribution format exchange profile (DFXP) of the timed text authoring format (TT AF) in terms of a vocabulary and semantics thereof.
The timed text authoring format is a content type that represents timed text media for the purpose of interchange among authoring systems. Timed text is textual information that is intrinsically or extrinsically associated with timing information.
The Distribution Format Exchange Profile is intended to be used for the purpose of transcoding or exchanging timed text
