【 摘 要 】

With the emergent and rapid development of mobile technologies, more and more multimedia applications run on handheld devices in mobile networks. This raises new challenges to mobile multimedia information systems. In this paper three technical aspects are considered as tightly intertwining and crucial for developing mobile multimedia applications: context awareness, multimedia adaptation, and mobility. An approach to integrating multimedia metadata standards such as MPEG-7 and MPEG-21 into context-aware ontologies effectively and seamlessly is proposed and related algorithms are extended. A context-aware mobile multimedia application (CA3M) is implemented and evaluated as a proof of concept. The evaluation results of the prototypes show the soundness of the concept. Open issues and development potentials for further research in the area of context-aware mobile multimedia information system development are addressed.
