(National Television System Committee standard) Standard regulating analog television signals in North America, Japan, and parts of South America, originated by the National Television System Committee. North America and Japan established NTSC color standards to make signals compatible with black and white transmissions. NTSC is based on the 60-hertz rate of U.S. electrical mains. An NTSC set can display 525 scan lines at approximately 30 frames per second, but nonpicture lines and interlaced scanning methods make for an effective resolution limit of about 340 lines. NTSC bandwidth is 4.2 megahertz. See also PAL, SECAM.
