Abstract

MPEG-4 is an ISO/IEC standard which defines a multimedia system for communicating interactive scenes. An MPEG-4 audio-visual scene is composed of various types of media data that are represented as individual objects. It includes a scene description that refers to the spatio-temporal specifications and behaviors of the individual objects. Particularly in the presentation of an MPEG-4 scene, object-based user interaction is possible within the limit set defined by the author. In this paper, we propose an MPEG-4 scene authoring tool which provides facilitative tools for composing interactive behaviors of the objects. The authoring tool presents a graphical interface for building a temporal scenario of MPEG-4 scenes. It also proposes new means of graphically representing an interactive scenario.
