Abstract
La Nature for Sept. 1 is devoted exclusively to an inquiry on television and broadcasting. The views of several eminent technicians both in France and other countries are given. Manfred von Ardenne “takes an optimistic view of the progress of television in Germany and looks forward to a great increase in the art before next winter. Maps are given showing a national scheme for radio diffusion in France and comparing it with the present system. A description is given of the new short-wave transmitter in Berlin, the largest in the world. Power of 15 kilowatts is emitted by waves seven metres long. It will help in the solution of certain problems in television and in producing broadcasting free from disturbance. The legal aspects of the problems which arise when a ‘listener’ is disturbed by induction from apparatus working in the neighbourhood are considered at length. Several law cases are quoted which show that the rights of listeners are recognised in France, and that those who use apparatus which interferes with the working of a private user's set are liable to substantial fines. The disturbances may be due to an electric motor driving a gramophone, neon tube lighting, the oworking of a cinema, the electric bell system on the ground floor, and public electric supply systems. In ocertain cases the use of devices to prevent interference is enforced. In conclusion, the influence of American improvements on the design of French receiving sets is discussed.
