The invention relates to a system for bidirectional audio and video recordin g and reproduction between at least two locations. Said system comprises, in addition to data transmission lines or transmitters and receivers, at least one respective television camera (7, 8, 9, 10; 25) and respective screen. Th e screen, which can be configured as a translucent projection screen (3) or as a belt (21), has at least one gap (4, 24) or break that acts as the view for t he television camera (7, 8, 9, 10; 25). The projected image is blanked out for the television camera (7, 8, 9, 10; 25). The gap (4, 24) and screen, in particular the projection screen (3) can be displaced transversally to the g ap (4, 24). The television cameras (7, 8, 9, 10; 25) and projectors (11, 12, 13 , 14; 28) are positioned in a fixed manner inside the rotating cylinder (2), i n such a way that the television cameras (7, 8, 9, 10; 25) compose images by scanning through the revolving gap (4, 24) and the projectors (11, 12, 13, 1 4; 28) simultaneously project stationary images onto the revolving projection screens (3).
