Abstract: The tutorial first presents a brief overview of multimedia applications needed for e-learning and shows some java applets and video clips of emerging multimedia services. It then introduces the fundamental networking technologies used for multimedia-based e-services. Particular emphasis is placed on the basic video and audio conferencing techniques, including the entire MPEG and H263. Next, the Internet protocols and languages, which are essential for the development of E-learning system, will be discussed. Fundamental e-security procedures and protocols are presented, as also new authentication and content protection procedures such as digital watermarking. The tutorial also demonstrates new multimedia applications in e-commerce, tele-learning, tele-collaboration, tele-training and tele-medicine using Collaborative Virtual Reality.
Objectives
More and more people are coming into contact with internet-based learn systems and websites that are rich in multimedia (graphics, animation, sound and video). This tutorial is for beginners as well as intermediate. Its objective is to present the state-of-the-art in multimedia enabling technologies, services and applications, over a variety of networks and protocols, with emphasis on giving practical advice on which multimedia technology to use for developing e-learning systems.
