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.
Both PAL and NTSC are video formats. PAL is the format used in Australia, parts of Asia, and some European countries. PAL stands for Phase Alternation Lines (625 lines) and offers more picture detail and wider luminance (color signal) bandwidth. PAL has been adopted by almost all 50 Hz countries in the world.
