Instantaneous translation of foreign film sound using portable receive - using film with magnetic sound track which is read and transmitted by ultra short wave or IR system

摘要

The cine film sound system with instantaneous language translation uses a magnetic track on the cine film. The magnetic track is read by heads fixed on the projector. The sound is retransmitted in the projection room by ultra short wave transmitters or by infra red beam transmitters. The transmitted sound is received by multichannel sound receivers. The system consists of several elements necessary for its operation. It has a multi track film recording system, and a projection system into which are incorporated several magnetic head sound readers. The system has several ultra short wave or infra red beam transmiters and several aerials fixed in the viewing room. It also has a multichannel system of sound receivers.
