High Definition Does Not Equal Two Times Standard Definition!

Dave Guerrero, Mike Richardson

High Definition video really is not a new concept. The NHK began working on a highresolution analog television system in 1968 and by 1980 had a working implementation. This system's technical standards included 1125 lines per frame, 20 MHz luminance bandwidth, 60 Hz field rate, and 5:3 aspect ratio. As with subsequent HD production systems, the NHK system addressed the need to present a wide screen image to the viewer.
