TELEVISION’S RANGE

Important Discovery laindon. February 4. Mr. It. A. Watson Watt, superintendent of the radio department nt the National Physical Laboratory, has informed the Royal Society of the discovery of three now electrified atmospheric regions between five and 40 miles above the earth, explaining why television transmission has reached greater distances than was expected. This is described as one of the most important discoveries of recent years. A British official wireless message from Rugby states that ns a result of experience gained in television transmission, the Television Advisory Committee has recommended that a sot of technical standards should lie adopted for pulilie transmissions from the London station. This recommendation has been approved by the Postmaster-Gen-eral, Mr. G. C. Tryon. It provides for the adoption of the following standards:—Number of lines ti picture. 105 interlaced: number of frames n second. 50; ratio of synchronisation impulse to picture, 30 to 70. These standards will not be substantially tested before the end of 1935. All future transmissions will be known as London television standards.
