RCA Developments in Television

A brief review is given of the studies made of the several characteristics of television images and other factors that have been effective in establishing standards, in determining satisfactory performance, and in guiding the step-by-step development of the RCA electronic system of high-definition television. — The system employs the “Iconoscope,” a cathode-ray tube for translating the visual image into electrical impulses, and the “Kinescope” for transforming the electrical impulses back into the variations of light-intensity to reproduce the image. The sensitivity and characteristics of the “Iconoscope” as a pick-up device are discussed. — The fundamentals of the RCA high-definition television system now under experimental field test in the New York area and the standards presently employed are reviewed. Photographs of the studios and other parts of the field-test facilities are included. A brief review is given to indicate the progress made and the results attained up to the present time in these field tests. — The technic of formulating and presenting television programs is peculiar to the requirements of television. The development of the technic is presently related to programs employing artists in studios, outside pick-ups, and motion picture film. The requirements of program technic are discussed.
