Abstract
An interactive multimedia presentation has a predetermined presentation play duration, a video content component (which may include video, audio, data, or any combination thereof), and an interactive content component. Methods and systems for playing the presentation include specifying a time when a particular media object is renderable. The time is specifiable using an application instruction that references either a first timing signal having a rate that is based on the play speed of the presentation, or a second timing signal having a continuous rate. One example of an application instruction usable as described above is an element associated with an XML data structure. An attribute of the element, such as the clock attribute, may be used to provide time values for the element that reference either timing signal. The attribute is used to maintain frame-accurate synchronization between the video and the interactive content components of the presentation.
