Abstract
HDTV (known as Hi-Vision in Japan), with its ability to provide through high- definition pictures on a large screen display advanced psychological effects such as sensations of reality and a visual impact unobtainable in conventional television, is the television system of the next generation. In Japan, daily one-hour experimental broadcasting was initiated in June 1989 using the BS-2 broadcast satellite, and regular service is scheduled to begin via the BS-3 satellite to be launched in 1990. To this end, a home-use receiver using VLSIs has already been developed. Moreover, HDTV is currently being applied in such diverse areas as film production, printing and publishing, medicine, and art museums. The HDTV system handles approximately five times the information of conventional television. As a result, a large screen display capable of maintaining stable resolution greater than twice that of conventional displays is essential to the full realization of HDTV's vast potential. This paper will first discuss HDTV's basic parameters, concentrating on the psychovisual effects, and explain some preferable display characteristics from this psychovisual point of view. It will then discuss the technical problems in developing such a display, and final ly describe the current state of HDTV display development.
