- Abbreviation of National Television Standards Committee Standard. A standard for the generation, transmission, and reception of TV signals. It provides for a resolution of 525 horizontal lines per frame, with 60 interlaced half-frames per second for a total of 30 frames per second. Of the 525 total lines, approximately 485 are active, while the aspect ratio is 4:3. NTSC is used in most of America and some Asian countries, while the other two main world standards are PAL and SECAM. All three are mutually incompatible. Also called NTSC (2).
