System aspects of multipoint videoconferencing
Abstract
Various types of terminals, which may be used for videoconferencing, are discussed in terms of expenses and human factor requirements. It is shown that fairly simple station sets, e.g. video telephones, may be well suited for multipoint conferencing while providing continuous presence of all conferees in sound and picture. A look at network requirements results in search for 'information nodes', i.e. nodes within a network, where all the information from each of the conference sites is available. It is shown that networks using distributed switching are well suited for using centralized switching can and have to be adapted for multipoint applications. In multistar-configured networks the need for dynamic allocation of channel capacity between exchanges and distributed processing of audio and video information arises.
