An Adaptive Multimedia Content Agent for Heterogeneous Client Device

Abstract

The rapid growth of multimedia content in the network makes more and more network appliances connected to Internet. The multimedia contents delivery over the Internet needs to address the capabilities of diverse client platforms. In order to adapt the multimedia contents to optimally match the capabilities of the client devices, we present an adaptive multimedia content agent which supplies content representation scheme and content customization. The content representation scheme called InfoPyramid provides multiple resolutions and multiple modalities for media contents. The content customization called policy engine selects suitable media contents adapted to the constraint of client capabilities. For policy engine, it process the resource requirements of the media content items according to the capabilities of the client devices using greedy algorithm based on value-framework for multimedia content transcoding. It also allows the prioritization on the content items with their importance in a web document. Furthermore, our agent-based content adaptation system adapts the news content to PC, PDA and cellular phone.
