|Title:||PROVIDING REAL-TIME SCHEDULING SUPPORT FOR MULTIMEDIA APPLICATIONS||Authors:||TAN TEIK GUAN||Issue Date:||1998||Citation:||TAN TEIK GUAN (1998). PROVIDING REAL-TIME SCHEDULING SUPPORT FOR MULTIMEDIA APPLICATIONS. ScholarBank@NUS Repository.||Abstract:||Providing real-time scheduling support for multimedia applications is an important. issue which has been largely ignored till now. While there has been much advances in hard real-time scheduling techniques over the past two decades, the direct application of these techuiques to multimedia. applications does not produce the desired results. This is so as the emphasis and execution requirements of hard real-time applications and multimedia applications differ. For the contributions in research, we will address the issues involving scheduling multimedia applications, focusing especially in the area where conditions are indeterministic and overloaded. This is because such situations contradict the requirements of hard real time systems and hence researchers have given little attention or avoided them totally. A multimedia application environment, named ICute, is built to provide a stable development and execution environment for multimedia applications in UNIX. It is also used as a testbed to help study the effects of multimedia execution under different scheduling techniques. By far, one strategy which has produced significant results is the use of frequencies and filtering to manage overloaded situations. It gives the programmer greater control over the proportion of degradation as well as stability during execution. In the thesis, we will present the implementation details and features found in ICute. We will abo describe the multimedia task system we used as out· basis for schedule- ing analysis and most importantly, cover the different scheduling techniques and support provided, with a thorough examination of the performances using simulation and actual experimentation.||URI:||https://scholarbank.nus.edu.sg/handle/10635/153417|
