ABSTRACT:
The invention relates to a system for bidirectional audio and video recording 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. The 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 the 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 gap (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), in 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, 14; 28) simultaneously project stationary images onto the revolving projection screens (3).
