An Adaptive Scene Compositor Model in MPEG-4 Player for Mobile Device

MPEG-4 supports dynamic scene composition through various interactions such as adding/removing/replacing objects and changing object’s properties. MPEG-4 content can express rich meanings through various dynamic scene composition by object-based, and can be played to mobile or desktop environment. Therefore, the MPEG-4 player must effectively play according authoring purpose and meaning, and compose dynamic scene in any device. This paper proposes an adaptive scene compositor model. It is optimized for dynamic scene composition of MPEG-4 content in mobile device. This model supports exact analysis of the scene description, core information extraction for rendering through extraction rule table and object-based information management for object’s reusability and flexibility.
