Abstract: Multimedia documents differ significantly form traditional documents that are composed of text and possibly geometric graphics. The introduction of continuous media such as audio, video, and computer generated graphics (e.g. animation) imposes new requirements on document representation. In contrast with static media (e.g. text and graphics), continuous media are presented according to a specific rate and duration. While traditional documents consists of a sequence of pages that can be read, multimedia documents are viewed as a presentation that changes continuously with time. This presentation is referred to as the playback of the document. An author creates a multimedia document that will be seen and heard by a viewer. The multimedia document creation process includes the creation of a presentation schedule to specify when the multimedia objects contained in a document will be rendered. In this thesis, a time-based multimedia document architecture called MEDIADOC is presented. This architecture contains rules and guidelines for the creation and representation of multimedia documents. It is a time-based model since it provides support for the creation of presentation schedules that will drive the playback of multimedia documents. Our model integrates many of the concepts of document representation including logical structures, layout structures, and presentation schedules. Special multimedia authoring tools and system support, which are required to facilitate the potentially complicated nature of multimedia document creation and manipulation, are also discussed. MEDIADOC was implemented as part of a multimedia authoring system. The discussion of the implementation includes a description of the authoring system, the object-oriented methodology that was used for implementing MEDIADOC, and the creation of a sample multimedia document.
