In this paper, we propose a multimedia server scheduling technique to efficiently integrate hard real-time and multimedia soft real-time tasks in the same system. For two different classes, we show how to adjust the fraction of the CPU bandwidth assigned to each task using the adaptable scheduling where each task instance is split proportionally into the server. The proposed method is capable of minimizing the mean tardiness of multimedia tasks, without jeopardizing the schedulability of the hard tasks. The performance of this scheduling method is compared with that of similar mechanisms through simulation experiments.
