BIFS (BINARY FORMAT FOR SCENES): Scene Description MPEG-4 Systems OBJECT COMPOSITION TECHNOLOGY: Description of relationship between A/V Objects that constitute a scene BIFS (BINARY FORMAT FOR SCENES): Scene Description Attributes of media objects (A/V properties) Structure of scene graph Pre-defined spatio-temporal changes Triggered spatio-temporal changes OD´s (OBJECT DESCRIPTORS): relationship between the Elementary Streams pertinent to each object FV/SLM-Benzler

BIFS (Binary Format for Scenes) Scene objects and spatio-temporal relationships Pre-defined set of 2D and 3D primitives nodes and fields Natural and synthetic audio-visual objects and their attributes The BIFS-Anim protocol: stream animations of node parameters. Animation of the content; Interactive behavior of individual objects by linking event source fields to event sink fields between different nodes. The BIFS-Command protocol: stream scene change insert scene replace nodes delete fields FV/SLM-Benzler
