• (written as PAL)
    Acronym for phase-alternating line, phase-alternation line, or phase-alternate line. A standard for the generation, transmission, and reception of TV signals. It provides for a resolution of 625 horizontal lines per frame, with 50 interlaced half-frames per second for a total of 25 frames per second. Of the 625 total lines, approximately 576 are active, while the aspect ratio is 4:3. In PAL, the phase of certain color information is inverted from scan line to scan line, so as to minimize phase distortion. PAL is used throughout most of Europe and many countries around the world, such as China and Brazil, while the other two main world standards are NTSC and SECAM. All three are mutually incompatible. Also called PAL standard.
