The Internet-mediated distance learning has received a lot of attention in both universities and corporations in the past few years. With the proliferation of new network and multimedia technologies, there is an increasing need for delivering TVlike video lectures. The Cisco IP/TV system has been widely used as an efficient platform in supporting TV-like lectures in MPEG-1 format. However, since it relies on Microsoft multimedia technology, IP/TV cannot be architecture-neutral. Further, in spite that a Web interface to IP/TV is provided, it lacks in application program interfaces to endorse the development of interaction applications between instructors and students. Both limitations can be relieved by appealing to the emerging Java technology. However, playing RTP/MPEG objects using JMF (Java Media Framework) is a non-trivial task. This paper presents a novel Java-based TV-like distance learning system by integrating Cisco IP/TV and Java JMF technology so that the superiority of both models can be complemented. In particular, we enhance the JMF engine to make playing RTP/MPEG media objects over the Internet possible. This system offers two learning modes, namely on-demand learning via unicast connection and scheduled learning via multicast connection. A course sample and its performance evaluation are illustrated to validate the effectiveness and efficiency of delivering TV-like courseware. Furthermore, synchronous distance learning services can be implemented at less cost.

“…For example, management information systems consisting of a network of client PC's and database servers are described in [30] and a system used by a telemarketing company is analyzed in [22]. A client server architecture has been proposed for a distributed learning environment tool in [4]. Client server systems have also been used to provide a middle layer between the user and a legacy mainframe-based system [18].…”

The innovation and diversification of development in multimedia technology and network infrastructures have brought a significant impact to education, especially for distance learning. This paper presents a model-based asynchronous distance learning system development that consists of a presentation semantic model called the multimedia augmented transition network (MATN) model and an asynchronous distance learning system called the Java-based Integrated Asynchronous Distance Learning (JIADL) system. The MATN model is powerful in modeling the synchronization and quality-of-service (QoS) for distance learning multimedia presentations. The JIADL system can support diverse asynchronous distance learning services by integrating RealPlayer and Java technology to augment the superiority of both models. A course sample is used to illustrate and validate the effectiveness of the system. How to use the MATN model to model the diversity requirements of a distance learning multimedia presentation is also discussed. Furthermore, the initial experimental results show that our system is cost effective and has a wide range of applications.
