IEE Electronics Division: Chairman´s address. Capturing the living image the impact of technology on TV production

The recent developments in TV technology are reviewed, and it is seen how, since the Second World War, it has been possible to design progressively lighter cameras and signal processing equipment, increasing the convenience of TV production in general and particularly outside broadcasts and electronic news gathering (ENG). Transistors, which began to replace vaccuum tubes in the 1950s, and, more recently, charge coupled devices, have played a considerable part in the technological changes described. Recording techniques have also been very much improved over recent years, and a very economical packing of digitised signals on a tape of convenient size has been achieved. Editing of video tapes is now possible without the need for a computer-type magnetic store. The author foresees a continuous development of TV broadcasting techniques in the future.
