HTML+TIME 2.0 Reference

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

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 XML-based elements and attributes, you can add images, video, and sounds to an HTML page, then synchronize them with HTML text elements over a specified amount of time.

Thus, HTML+TIME technology allows you to create multimedia-rich, interactive content on a Web page with little or no scripting. Because HTML+TIME adds timing to a document through new attributes on existing HTML elements, you can use your existing HTML knowledge when you add timing to a page. The HTML+TIME attributes specify when an element appears on a page, how long it remains displayed, and how the surrounding HTML elements are affected, allowing you to create animation effects. In addition to the attributes, some new XML-based elements have been created to simplify the incorporation of media into Web pages.

The topic areas listed below provide access to the object model exposed by the time2 behavior.

HTML+TIME References by Topic

Animation Introduction to HTML+TIME allows Web authors to animate content on the page by changing the value of particular attributes and properties over time. Without using script, you can animate an element's color; move an element along a specific path or between intervals; cause elements to appear or disappear over time or in response to events; or accelerate, reverse, or loop an animation.
Microsoft DirectMusic Authors can add sophisticated musical content to Web pages by combining the timeline control and synchronization offered by Introduction to HTML+TIME with some of the attributes and properties provided by the DirectMusic API. DirectMusic provides support for MIDI, downloadable sounds, and consistent playback on the Windows platform.
Media 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 simpler for Web authors to provide tightly synchronized multimedia presentations, and to coordinate media and animation without using script.
Time Containers By providing a timing model that unifies a rigid timeline with event-based timing relationships, Introduction to HTML+TIME makes it easy to synchronize media elements, control animations, and add timed, interactive content to a Web page without using script.
Transitions Introduction to HTML+TIME provides support for Introduction to Filters and Transitions, which allow you to apply multimedia-style effects to your Web pages. Visual filters are extensions to CSS properties that change the display of an object's contents. Transitions are time-varying filters: they affect the way content changes in an object are displayed. You can apply visual filters and transitions to standard HTML controls, such as text containers, images, and other windowless objects. Although filters and transitions can be implemented as script, Introduction to HTML+TIME allows Web authors to combine filters and transitions with timeline control and animation without using script.
Other Features These links provide access to additional features of the object model exposed by the time2 behavior, including content control elements, system test attributes, timing attributes and properties, and several overviews on Introduction to HTML+TIME functionality.

HTML+TIME Overviews and Articles

Introduction to HTML+TIME HTML+TIME, first released in Internet Explorer 5, adds timing and media synchronization support to HTML pages. Using a few 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.
Basics of HTML+TIME Animation This article introduces you to the basics of HTML+TIME animation, so that you can create an exciting Web experience for your users.
Controlling Child Elements Using HTML+TIME: Time Containers HTML+TIME 2.0 comes equipped with three time containers that enable you to control how timed interactive child elements behave on your Web pages. These time containers enforce time relationships with their corresponding child elements, control the amount of time that children may be active, and define the relationships among a set of grouped child elements.
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.
Incorporate the time2 Behavior This tutorial explains how to incorporate the time2 behavior in your Web pages so you can begin using timelines, multimedia, and animation with HTML elements.
Initiating Timed Elements with the begin Attribute This overview provides you with the syntax for the begin attribute and describes how to initiate timed interactive HTML+TIME elements using the time2 behavior implemented in Internet Explorer 5.5.
Getting Started with HTML+TIME HTML+TIME enables you to support timed, animated, and multimedia content in your pages. Using a few XML-based elements and attributes, you can synchronize media playback with text and other elements and animate content in your Web pages without using script.
Spice Up Your Web Pages with HTML+TIME HTML+TIME provides a declarative means for adding multimedia and interactivity to Web pages. You don't need to know script to use HTML+TIME, so you can focus on creating the content instead of learning a programming language.
Using HTML+TIME Transitions It is now possible to create transitions with HTML+TIME quickly, without writing script. To get started, you need only learn one new HTML+TIME element called t:TRANSITIONFILTER and a few of the t:TRANSITIONFILTER attributes.
