HTML+TIME: Media

This topic documents a feature of HTML+TIME 2.0, which is obsolete as of Windows Internet Explorer 9.

Introduction to HTML+TIME provides extensive support for media playback through media container elements, a unified timeline model, a variety of media-specific attributes and properties, and system test attributes. These features make it easy for Web authors to provide tightly synchronized multimedia presentations, and to coordinate media with animation, without using script.

The following links provide access to the object model exposed by the time2 behavior.

About Content Selection: System Test Attributes and t:SWITCH

HTML+TIME 2.0 provides authors with the option to display different elements based on system settings.

Seeking With HTML+TIME

In HTML+TIME (Timed Interactive Multimedia Extensions) various types of media, animation, and other time elements can be played over a period of time. It is often desirable to be able to jump to any point on this time line. This process of jumping to different points on a time element's time line is called seeking.

Using the HTML+TIME Document Object Model (DOM)

All HTML+TIME objects are accessible through script at run time. This article introduces you to the HTML+TIME objects, methods, events, and properties available to your Web pages.
