Phase Alternating Line (PAL) is a colour encoding system for analogue television. It was one of three major analogue colour television standards, the others being NTSC and SECAM. In most countries it was broadcast at 625 lines, 50 fields (25 frames) per second, and associated with CCIR analogue broadcast television systems B, D, G, H, I and K. The articles on analogue broadcast television systems further describe frame rates, image resolution, and audio modulation.

NTSC (an acronym of National Television System Committee) was the first American standard for analog television, published and adopted in 1941. It was one of three major color formats for analog television; the others were PAL and SECAM. NTSC color was usually associated with System M, and this combination was sometimes called NTSC II. A second NTSC standard was adopted in 1953, which allowed color television compatible with the existing stock of black-and-white sets. The EIA defined NTSC performance standards in EIS-170 (also known as RS-170) in 1957.
