A Scene Representation Application Implementing LASeR Using Object-Based Timing Model

In this paper, we present a multimedia scene representation application implementing MPEG4-Part 20 Lightweight Application Scene Representation standard (LASeR). In an interactive multimedia scene, we are usually concerned about two questions: (i) The spatial-temporal management of scene elements; (ii) How to manage the interaction between the user and the multimedia scene. In this paper we propose an object-based timing model to ensure all the elements are rendered in correct time, and we also propose corresponding strategies to deal with the user’s actions. At the end of this paper, we show some instances of the rich-media system. The future of rich-media is also considered.
