MPEG-4 3D Inhalterstellung am Beispiel eines 3D-Benutzerhandbuchs für Kfz FV/SLM-Benzler
Overview • Introduction • MPEG-4 Systems • BIFS • „Tool Chain“ for Content Creation • Demonstration FV/SLM-Benzler
Objectives MPEG-4: Transmissionand 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
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
MPEG-4 Systems Scene Description: BIFS (Binary Format for Scenes) MPEG-4 Scene BIFS Scene graph 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
BIFS Text • BIFS TEXT TO MPEG-4 FORMAT • MP4 Format: MP4Tool • M4P Format: M4PGen and BifsEnc MPEG-4 Browser BT Format: Scene Descr. Initial OD OD´s MP4 Tool MP4 BIFS Text Scene Descr. BifsEnc HHI Player BIF M4PGen M4P SCR File: Initial OD OD´s FV/SLM-Benzler

Demonstration • No javascript • Combination of 2D and 3D primitives • BIFS-Anim • BIFS-Commands in Conditional nodes and Update frames • Limitations: • Not all nodes implemented in Browsers • Time-stamping on cascade of REPLACE ROUTE commands • Display and semantic differences between Browsers • 2D Authoring Tool: pixelMetrics • Mp4Tool: limited node ID´s FV/SLM-Benzler
