SMIL is a language for describing audiovisual presentations on the web.


SMIL

SMIL (Synchronized Multimedia Integration Language) was designed to enable multimedia presentations on the web.

A SMIL presentation can be composed of audio, video, images, text, and other media types.

You can read more about SMIL in our SMIL Tutorial.


HTML+TIME

HTML+TIME stands for Timed Interactive Multimedia Extensions for HTML. It is a proposal for adding SMIL 1.0 timing and synchronization support to HTML.

HTML+TIME was submitted to the W3C by Microsoft, Macromedia, Compaq/Digital and Digital Renaissance.

You can read more about HTML+TIME in our SMIL Tutorial.


HTML+SMIL

HTML+SMIL (a modification of HTML+TIME) was included in an early SMIL 2.0 Working Draft.

When SMIL 2.0 became a W3C Recommendation, HTML+SMIL was removed from SMIL 2.0 and added as a separate Working Draft named XHTML+SMIL.


XHTML+SMIL

XHTM+SMIL provides support for SMIL 2.0 functionality like animation, media, timing, synchronization, and transitions directly in XHTML.

You can read more about XHTML+SMIL in our SMIL Tutorial.
