| NTSC | Short for National Television System
Committee. The NTSC is responsible for setting television and video
standards in the United States (in Europe and the rest of the world, the
dominant television standards are PAL and SECAM). The NTSC standard for
television defines a composite video signal with a refresh rate of 60
half-frames (interlaced) per second. Each frame contains 525 lines and can
contain 16 million different colors. The NTSC standard is incompatible with most computer video standards, which generally use RGB video signals. However, you can insert special video adapters into your computer that convert NTSC signals into computer video signals and vice versa. |
