TELEVISION PROGRESS

AN IMPORTANT DISCOVERY )_ ELECTRIFIED REGIONS LONDON, Feb. 4.' Mr R. A. Watson Watt has informed the Royal Society that the discovery of three new electrified atmospheric regions between five and 40 miles above the earth explains why television transmission has reached greater distances than were expected—namely, 50 instead of 25 miles. This is described as one of the most important discoveries of recent years. TECHNICAL STANDARDS ■ • British Official Wireless) RUGBY, Feb. 4. As a result ".of the experience gained of television transmission, the Television Advisory Committee has recommended that a set of technical standards should be adopted for public transmissions from the London station. This recommendation has been approved by the PosN master-general. It provides for the adoption of the following standards:—Number of lines per picture, 405; interlaced number of frames per second, 50: ratio of synchronisation impulse io picture, 30 to 70, These standards will not be substantially tested before the end of 1938. All future transmissions will be known as London television standards.
