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 IP. Although teleteaching and videoconferencing have similar QoS requirements, teleteaching functional requirements are a superset of those of videoconferencing. The suitability of H.323 technology and its currently available products for supporting teleteaching services is investigated, based on experience gained during a related deployment at the University of Athens.
