Use of a video line amplifier to pre-compensate for high-frequency video signal transmission losses resulting from long distance cable runs (several hundred meters) by boosting those signal frequencies most effected. Without such compensation, deterioration is manifested as loss of fine details and color distortion.
Industry:Software
Literally single color, usually used to indicate black and white. There have been monochrome high line rate cameras and displays for many years. The EIA has standardized rates of up to 1225 scanning lines per frame. NHK developed a monochrome HDTV system with 2125 scanning lines per frame. Even higher number of scanning lines are used in conjunction with lower frame rates in cathode ray tube scanners used in printing and in film. These extremely high rates are possible because monochrome picture tubes have no triads.
Industry:Software
Tendency of the eyes to follow the sequentially flashing scanning lines of interlaced scanning up or down the screen in the same way that the eyes follow the sequentially flashing light bulbs on a movie theater marquee. Line crawl tends to reduce vertical resolution.
Industry:Software
The transmission of a signal wave which represents the brightness values in the picture but not the color (chrominance) values in the picture.
Industry:Software
Any number of schemes to convert interlaced scanning to progressive scanning at the display, the simplest of which simply doubles each scanning line. More elaborate schemes use line interpolation and motion compensation or median filtering.
Industry:Software
The number of horizontal scans per second, normally 15,734.26 times per second for NTSC color systems and 15,625 in PAL.
