Terminals for multipoint teleconferences

The authors report on their comparative examination of different variants of a multipoint teleconferencing system in order to obtain information about requirements for systems and terminals for work-place conferences. In particular they discuss conferencing from studios and work-places, system variants (such as sound conferencing, and picture conferencing with still and with moving pictures), and terminals for conferencing (using telephones, sound, picture and facsimile). They give examples of work-place systems for sending documents and personal data.
