碩士 === 淡江大學 === 資訊工程學系 === 86 === Because of the prevailing of multimedia computer and the computer network,the multimedia applications are greatly applied in many areas. Due to thecomplication of multimedia objects and the demand of distributed technologyfor multimedia objects, the whole period of software development extendsand the cost of software development equally increases. However, someprogram codes can be reused and doesn't need re-coding. The purpose ofapplication framework offers programmer in the skeleton of application andthe shorter time of application developing. Therefore, we develop theDistributed Multimedia Object-Oriented Application Framework (DMOOAF) inorder to solve the problem. The thesis quotes the object-oriented technologyspecialize the current object oriented application framework and add someclass hierarchies according to the properties of multimedia objects. Furthermore, We use abstract classes to improve the across- platform andportability. To reach the high interaction of multimedia, we use Model ViewController provided by SmallTalk-80, as the basis architecture of applicationframework. In addition, we add multimedia presentation classes、 multimediasynchronization classes、Flexible Quality of Service classes, such that thecycle of software development can be reduced and have the properties ofreusability and extensibility to suit the rapid changed of the multimediaobject formats and the method of presentation.
