At the end of the 1960s, the idea for a high definition television (HDTV) system was proposed by Japan Broadcasting Corporation (NHK) as a future TV system. The picture configurations and signal specifications were established by results of psychological and engineering experiments. After decades, development of most equipment for trial broadcasting service was completed and it was named “Hi-Vision”. We, Sony supplies all equipment for Hi-Vision system.The main purpose of Hi-Vision was to achieve a direct satellite broadcasting (DSB) service, although its high resolution picture characteristics had fascinating potential for applications to pictorial information media including various electronic imaging in the non-broadcasting fields. This paper introduces the applications of Hi-Vision system to electronic imaging. The discussion is primary with regards to application of it to still picture imaging.
