| Summary: | 碩士 === 國立彰化師範大學 === 資訊管理研究所 === 93 === In order to describe classing multimedia presentation which contained each kind of media, the present thesis has designed a set of descriptive model, is called Classing-based Multimedia Descriptive Model(CMDM). This model penetrates the way which the XML label defined to describe the position, the time media appears as well as the classing condition, and provides some attributes to let various media objects present on the browser and enable the entire presentation play accurately and smoothly.
Using this description model may cause the content of multimedia application even more to be rich, but manufactures process actually even more fast and easy. So, we only must focus on designing the script of presentation playing, including the appeared time, the appeared position and so on, and may simply manufacture each kind of different multimedia applications.
The description model we proposed may not only provide the time control media appears and the layout control media locates, but also has joined the classing concept. By means of the classing mechanism, the multimedia application may even more be appropriate and personal.
