MPEG-21 digital item Processing

This paper introduces the concept of MPEG-21 Digital Item Processing (DIP), which enables the incorporation of interoperable descriptions of programmability related to the multimedia experience. In the first part of the paper, a motivation for defining DIP is outlined and the different terms and definitions used within DIP are defined and discussed. The second part of the paper gives an overview of the current development status of DIP and discusses the Application Programming Interfaces provided to the Digital Item Method author. This illustrates how DIP can be used to interact between the different parts of MPEG-21. A walkthrough of the DIP process is given enabling the creation of a truly interoperable MPEG-21 DIP peer. Finally, the paper ends with some conclusions and gives some insight on what can be expected for DIP in the future.
