Phase Alternating Line (
PAL) is a colour encoding system for
analogue television used in broadcast television systems in most countries broadcasting at 625-line / 50 field (25 frame) per second (
576i). Other common colour encoding systems are
NTSC and
SECAM. This page primarily discusses the PAL colour encoding system. The articles on
broadcast television systems and analogue television further describe frame rates, image resolution and audio modulation.
