The PAL format (Phase Alternating Line) is the standard-definition television
format for the countries of western Europe, including the United Kingdom,
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.
