Potential and limitations of a teleteaching environment based on H.323 audio-visual communication systems
The effective support of teleteaching services requires the development
of multimedia collaboration systems that are capable of providing
real-time and high quality audio-visual communication among distributed
instructors and students. In the absence of such specialised systems,
technologies tailored to other services are being considered for
teleteaching services as well. Such a technology is the H.323
audio-visual communication technology developed to support video
communication over IF. Although teleteaching and videoconferencing have
similar QoS requirements, teleteaching functional requirements are a
superset of those of videoconferencing. In this paper, the suitability
of H.323 technology and currently available products to support
teleteaching services is investigated, based on experience gained during
a related deployment at the University of Athens. (C) 2000 Elsevier
