| Definition: | simultaneous colour television system using, in baseband, a composite colour signal comprising a luminance signal and two chrominance components which are transmitted as quadrature amplitude modulation of a subcarrier, and in which, on each line, the polarity of one of the chrominance signals is inverted
NOTE 1 – In most actual applications of PAL the scanning system uses 625 lines and 50 fields/second. The colour signal is transmitted using vestigial sideband amplitude modulation, and the sound is transmitted as frequency modulation of a separate radio-frequency carrier.
NOTE 2 – PAL is derived from "Phase Alternation Line".
NOTE 3 – There are different versions of PAL, defined in CCIR Report 624.
