Building a Multi-purposes Digital Media System Using MPEG-21 and XML

Abstract

This study proposes a scheme to integrate several types of media elements into a multimedia framework, which plays media on a same platform without distinct players. This investigation is well-suited for multimedia applications such as the distance learning and digital library. However, the varied media elements put together and played on a same platform are great challenges. This study employs MPEG-21 digital item standard to achieve this target, makes varied multimedia exist on a browser interface, and solves the problem of different players playing different media. Moreover, this study exploits XML and Digital Item Declaration Language (DIDL) functions to construct a Digital Media System (DMS). The DMS puts separate videos, audios, images, and text media sources into a trailer. Users select and play the trailer using web-based interface to achieve on demand playing. Finally, we demonstrate that the proposed system is resilient on multimedia applications and very suitable for distance learning systems.
