Design issues and alternatives for setting up real-time interactive Telelectures

Abstract

The continuous technological advances in networking and multimedia systems stimulate the integration of real-time interactive telelectures as an important service of a telelearning environment. Real-time interactivity is a key technological factor for the success and dissemination of telecourses. CUI (Centre Universitaire lnformatique) at the universiO~ of Geneva and GMD (the German National Institute for Information Technology) atBonn ran real-time interactive telelectures on a regular basis for one academic year. In this paper we describe the experience we gained out of the experiment, design issues we investigated and technical problems we had to deal with.

Effectiveness of Teleconferencing in Nigerian Universities: A Descriptive Approach

“…Teleconferencing is assisted by some software, which allows people who are geographically dispersed to hold conferences by means of sending and receiving multimedia data over networks. Examples of teleconferencing applications include video conference (Breiteneder, Gibbs & Arapis, 1996;Dorcey, 1995), teleteaching (Arapis, Konstantas & Pilioura, 1998), and telepresentation (Gemmell & Bell, 2007). Other examples include video phone and audio chat.…”
