Explanation

"High-vision" is the popular name of the high-definition TV broadcasting (HDTV) that has been promoted with Japan Broadcasting Corporation (NHK) at the forefront of HDTV development. At first, although it originally referred to HDTV by analog technology (which began experimental broadcasting in 1989), "high-vision" today is widely used and includes digital HDTV. High-resolution pictures (formed by scanning 1125 lines) on a horizontally-wide screen (i.e., a horizontal-to-vertical ratio of 16:9) is a characteristic of high-vision TV.
