Abstract
An MPEG-4 scene is the specification for generating interactive multimedia contents. Each object constituting an MPEG-4 scene runs according to its own run time. Likewise, it should support the update of predefined temporal relations and attributes by the user event taking place during run time. Nonetheless, BIFS, which is the scene description of MPEG-4, does not support the temporal relations among the objects; neither is it capable of controlling the variance of temporal properties by user events. This paper defined the temporal relations and its related events that are helpful to the effective authoring of MPEG-4 and introduced temporal constraints to generate error-free scenes for user events taking place during run time. Furthermore, an authoring system of MPEG-4 contents was developed together with this application.
