We developed technologies for transmitting video contents over wireless platforms, and encapsulated these video delivery and presentation technologies into a client system for accessing a multimodal digital video library. The mobile access system, iVIEW client, provides a user interface that meets the challenge of rich multi-modal information presentation on wireless hand-held devices. An XML schema is employed to organize the multi-modal metadata for better data interoperability. Furthermore, we investigated a context awareness mechanism complementary to the XML schema to facilitate scalable degradation under restricted resources in wireless application environment. This paper presents the design, implementation, and evaluation of the iVIEW system and its associated technologies for video information management and delivery on pervasive devices over wireless networks.
