The PAL format (Phase Alternating Line) is the standard-definition 
                  television format for the countries of western Europe, including the 
                  United Kingdom, Ireland, France, Germany and other countries. The 
                  PAL video format definition is 25 interlaced frames per second, 625 
                  resolution lines per video frame.
                  Home video products for use in Europe should be in the PAL format 
                  to properly display both picture and sound. However, home video 
                  products manufactured in the NTSC and SECAM television formats 
                  may image properly on PAL television systems, as those disc players 
                  often have built-in cross-format compatibility. 
                  As with other standard television formats, PAL is being phased out 
                  for the generally universal AVCHD high-definition format.
