SECAM

SECAM (Séquentiel Couleur à Mémoire - Sequential Color with Memory) is an analog, color broadcast standard developed in France that uses a frequency modulation scheme on its color subcarrier. It was an early European attempt at color television that was created in part to resolve a hue problem with the NTSC standard.

SECAM transmissions are more robust over long distances than NTSC or PAL. Audio is transmitted at the same speed as PAL – slightly faster than NTSC. By the end of the 20th century, SECAM broadcasts were primarily used in French speaking countries and countries once associated with the U.S.S.R.
