The MPEG-21 Multimedia Framework

•
•
Alpen-Adria-Universität
Alpen-Adria-Universität

The document summarizes a presentation on MPEG-21 given by Dr. Christian Timmerer. MPEG-21 aims to create an interoperable multimedia framework with three steps: understanding relationships between components, developing new specifications to fill gaps, and achieving integration of standards. A key concept is digital items, which are structured digital objects with identification and metadata. Digital items can be adapted and processed to satisfy transmission, storage, and consumption constraints.
