This section contains reference information on 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.
Overviews
About Content Selection: System Test Attributes and t:SWITCHHTML+TIME 2.0 provides authors with the option to display different elements based on system settings.
Animating with keyTimes and keySplines
Using the keyTimes and keySplines attributes, you can divide an animation element's simple duration into multiple segments, speed up or slow down the animation at multiple rates during a single duration, and specify values for the animation to reach at particular points in its duration.
Getting Started with HTML+TIME
HTML+TIME (Timed Interactive Multimedia Extensions) makes it fast and easy to support timed, animated, and multimedia content on your pages.
Seeking With HTML+TIME
In HTML+TIME 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 HTML+TIME with DirectMusic
This article briefly discusses some of the ways you can use HTML+TIME to add flexibility and control to Microsoft?DirectMusic?content on the Web.
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.

Sets or retrieves what action is taken on the element while the timeline is active.
timeContainer
Sets or retrieves the type of timeline associated with an element.
timeParent
Retrieves the parent time container element of the current element.
volume
Sets or retrieves the volume of the media file.
Methods
activeTimeToParentTime
Converts a value in the element's active timeline to the corresponding point in the parent timeline.
activeTimeToSegmentTime
Converts a value in the element's active timeline to the corresponding point in the segment timeline.
beginElement
Starts the element on the timeline.
beginElementAt
Starts an element's timeline at the specified time.
documentTimeToParentTime
Converts a value in the document timeline to the corresponding point in the element's parent timeline.
endElement

parentTimeToDocumentTime
Converts a value in the element's parent timeline to the corresponding point in the document timeline.
pauseElement
Stops playing an element's timeline at the current point.
resetElement
Removes any changes made to the element and returns the element to its original state.
