Like NTSC it is an interlaced format. Each frame consists of two fields (half-a-frame), each field has half of the lines of a frame (one has all the even lines, one has all the odd lines). Fields are transmitted and displayed successively. There are 50 fields per second. At the time of its design the interlacing of fields was a compromise between flicker and bandwidth.

PAL was first introduced in Germany in 1967.
