Abstract
This paper presents a presentation semantic model that is based on the augmented transition network (ATN) for asynchronous distance learning system called Java-based Integrated Asynchronous Distance Learning (JIADL) system. The JIADL system can support diverse asynchronous distance learning services. Unlike most related work in the literature, we integrate RealPlayer and Java technology so that the superiority of both models can be complemented. A course sample is illustrated to validate the effectiveness of the paradigm proposed. How to use the proposed multimedia ATN model to model the diverse requirements of a distance learning multimedia presentation is also discussed. The multimedia ATN model is powerful in modeling the asynchronization for distance learning multimedia presentations. Furthermore, in addition to supporting asynchronous distance learning, our system can be applied to a wide range of potential value-added applications.
