Abstract: With the increased demands in multimedia applications, the need to provide better system support is greater than ever. Multimedia applications have an added dimension of time in their execution which results in stringent timing requirements. These timing requirements are usually "soft" constraints, that is, they are potentially relaxable human preference constraints. In this paper, we investigate an approximating scheduling algorithm that attempts to derive a "good" schedule for multimedia processes even under the overload condition. A model is presented which is able to quantify the trade-off between conflicting goals in a multimedia application. Experiments are conducted to test the performance of the approximating scheduling algorithm. Results indicate that our proposed algorithm is able to adjust dynamically to transient overload situation without too much degradation in performance. © 1998 Published by Elsevier Science Inc.
