Abstract

"Accessing information anytime, anywhere, with any device" is a widely used slogan. The problem, however, is how to bring multimedia services to terminals with limited capabilities. Our approach offers a solution for delivering multimedia presentations to terminals connected to mobile or fixed networks with varying capabilities. Our media wrapper is used to adapt the original presentation according to end-to-end environment characteristics; e.g., the user, terminal, and network type. This paper presents a technique called 'media wrapper' that controls and models the media adaptation process. Using this approach, it is possible to scale and convert multimedia presentations to suit the end user's terminal by making only one original presentation and letting the media wrapper to scale it for the different environments. The adaptation is performed using special algorithms that are defined by dedicated software agents. The algorithms are implemented as agents and are controlled by the media wrapper management module. The agent control is managed based on knowledge base information that contains, e.g., logical rules consisting of the combinations of the needed adaptation parameters. The media wrapper uses CC/PP profiling for defining the parameters that affect the adaptation. These parameters concern terminal, network, and client behavior.
