Adding delivery support to MPEG-Pro, an authoring system for MPEG-4

MPEG-Pro, an MPEG-4 authoring software prototype has been designed to integrate all main authoring capabilities from audio/visual encoding to the final delivery of a complete MPEG-4 application. The storage format, named MP4, has been defined for MPEG-4, but adapted techniques for specific delivery scenarios that are compliant with this format are still in course of proposition and definition. We introduce a solution to author and store MPEG-4 content with better data accessibility for the streaming over RTP/IP scenario. By respecting scrupulously the MP4 constraints, this content remains reusable by any MPEG-4-compliant tool. We describe how its implementation is integrated in MPEG-Pro whose modular architecture allows large scope for extensibility.
