[Multipoint video-conference. An option for highly specialized education].

Video-conferencing via the PST (Public Switched Telephone) network is a good and economical alternative for use in education. If the universities cooperate, instruction by the best lecturers can be made available to small groups of students distributed over great distances. Travel costs will be minimised and teachers under pressure of time will be able to use their time rationally. Although the social intercourse of a study group promotes the students' mental energy to the benefit of instruction, such technical advances as more rapid transmission and audiovisual integration will be needed. Last but not least, efficient course secretaries will be required to coordinate the work both of lecturers and studio and telephone personnel, as well as the participation of the various study groups.
