[starttext]Worldwide Analog Video Standards

NTSC (National Television System Committee)
- The analog TV system used in most of the Americas, Japan, South Korea, Taiwan, Burma, and some Pacific island nations and territories. It is also the name of the U.S. standardization body that developed the broadcast standard.

PAL (Phase Alternating Line)
- PAL or Phase Alternating Line is an analogue TV encoding system used in broadcast TV systems in large parts of the world.

SECAM (Sequential Color with Memory) / SÉCAM (Séquentiel Couleur à Mémoire)
- SECAM or Sequential Color with Memory is an analog color TV system first used in France. It is also a compatible standard, which means that monochrome television receivers predating its introduction are still able to show the programs.

Because of SECAMs compatibility requirement, color standards add a second signal to the basic monochrome signal, and this signal carries the color information, called chrominance or C in short, while the black and white information is called the luminance or Y in short.
