Multimedia systems are very resources dependent. Using them in a varying wireless environment leads to a need for adaptation in order to cope with, for example, bandwidth variations, screen size and processor power diversity. We have developed an object oriented framework that provides mechanisms to specify adaptation strategies and to imple ment changes of behaviors in applications, depending on variations of the environment. Examples of possibilities to dynamically make significant adaptation are given for video on demand and live video streaming.
