PAL

Phase Alternating Line is an analog television broadcast protocol adopted by Europe (except France) and a number of other countries around the world, some with modified versions (such as PAL-M). The system used 625 interlaced lines at 50 Hz. Discontinuation of PAL transmission has begun in various parts of the world, with Western Europe and Australia having completed the transition to DVB-T digital video broadcasting, with other countries to follow. PAL scans the video image 625 times horizontally, or about 25 percent more than NTSC systems.
