Design and Implementation of Real Time E-Lecturing System

Abstract

Advancement in information and communication technology (ICT) is making video streaming a viable way of getting a real-time event to people anywhere in the world through computer systems and handheld devices. In teaching and learning, ICT have successfully added values to the process through the Internet. In this research, the process of delivering lectures in real-time to a wide audience was considered. A real-time e-Lecturing system was designed and implemented to aid easy communications between the teacher/trainer and the learners in different locations. The system grouped the learners into two. The first group is located in traditional-like classrooms without the trainer being with them. The learners can communicate directly with the trainer through full-duplex mode of communication using a projector with necessary audiovisual systems connected to a computer system. The trainer can see the trainees as in the traditional classroom through the computer system. The second group comprises connections through handheld devices and connected through simplex mode of communication. They can view and listen to lectures in real-time but cannot communicate with the trainer in real-time. The research shows a better way of blending traditional classroom with other learners located in different environment. It also proved to overcome the barrier of distance in learning and give some degree of flexibility to the leaner to decide where to receive lectures. The system will be useful for institutions operating multi-campus system and/or for courses involving large number of students without correspondingly large classroom/lecture halls. // Paper ID 219
