The emergence of mobile multimedia systems and the diversity of the supported multimedia applications put new challenges for their design. These systems must provide a maximum application quality of service (QoS) in the presence of a dynamically varying environment (e.g. video streaming and multimedia conferencing) and multiple resources constraints (e.g. remaining energy). To respond to the changing resource availability and application demands, a new class of adaptation method is emerged. It combines the adaptation simultaneously upon the different layers related to the target system. This paper presents a framework dedicated for mobile multimedia systems. It supports application QoS under real time and lifetime constraints via coordinated adaptation in the hardware, OS, and application layer. In this framework, we present a new middleware approach based on a global and a local manager. The global manager (GM) is used to handle large and long-term variations whereas the local manager (LM) is used to guarantee the real time constraint. The GM intervenes in three layers but the LM intervenes only in the application layer and OS layer. We have implemented this approach on reconfigurable platform using Altera technology.
