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.
The three differences between NTSC discs and PAL discs are: 1) Picture size and pixel aspect ratio (720x480 vs 720x576), 2) Display frame rate (30 vs 25), 3) Video from film is usually encoded at 24 frames/sec. but is preformatted for one of the two display rates.
