The Japan Broadcasting Corporation (NHK) started research into a future high-definition television system about ten years ago and is now taking the initiative in constructing such a system. Wide ranging studies, from desirable picture quality and television standards to broadcasting systems, development of new equipment from high-resolution cameras to wide screen displays, and transmission tests using this equipment, have been carried out. The present state of these studies and the development of the equipment are described.
