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.
With the advent of Digital HD TV the difference between NTSC and PAL is practically limited to the framerate of the display which is 23,975p/30p/60i on NTSC and 25p/50i on PAL standards. Modern, digital television sets will have no issues with any of them.
