2 „Tool Chain“ for Content Creation Demonstration
Overview Introduction MPEG-4 Systems BIFS „Tool Chain“ for Content Creation Demonstration FV/SLM-Benzler

3 2.Application demonstration in an automotive environment
Objectives MPEG-4: Transmission and interaction with audio-visual objects of synthetic or natural nature CONTENT DEVELOPMENT 1.Analysis of current technology 2.Application demonstration in an automotive environment FV/SLM-Benzler

4 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

5 MPEG-4 Systems Scene Description: BIFS (Binary Format for Scenes)
MPEG-4 Scene BIFS Scene graph FV/SLM-Benzler

6 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
