Hi-Vision - Computer Definition
The first high-definition (HD) TV system in Japan. Administered by the Japanese Broadcasting Corporation, or NHK (Nippon Hoso Kyokai), Hi-Vision first broadcast in the late 1980s. It was superseded by Japan's digital HD standard in 2007 (see ISDB). Using analog modulation, Hi-Vision delivered a 1035i resolution with a 15:9 aspect ratio. See HD analog formats, MUSE and ISDB.
