Easy Teach & Learn^(R): A Web-Based Adaptive Middleware for Creating Virtual Classrooms

Abstract

We present an architecture of a teleteaching system which supports direct interactions between all participants, i.e., lecturer and students and among students. To establish a kind of “virtual classroom” atmosphere, high-quality audio and video streams as well as teaching material are distributed between participants. For the implementation of high-quality audio and video channels, the system is based on emerging high-speed networks such as cable TV networks and any kind of digital subscriber line. A novel adaptive middleware takes care of system and network resources such that every participating user receives a teleteaching session in best quality possible. A first prototype is discussed.
