NTSC stands for National Television Standards Committee. PAL stands for Phase Alternating Line. NTSC is the standard broadcast format in the United States, while PAL is the standard broadcast format in Europe, Australia, and parts of Asia.
Other countries use Phase Alternating Line (PAL) format, which displays at 50 fields per second, but at a higher resolution (see How Video Formatting Works for details on these formats). Because of the differences in frame rate and resolution, an MPEG movie needs to be formatted for either the NTSC or the PAL system.
