(S�quential Couleur � Memoire, or in English, Sequential Color with Memory.) (SECAM) The television broadcast standard for France, the former USSR, and various eastern European countries.

American engineers perjoratively claim that SÉCAM stands for "System Essentially Contrary to the American Method". [1]

Like PAL and NTSC, SECAM is specifically the method of encoding the color portion of the video signal, and it can be used on many different scanning systems. Commonly, SECAM color is found in Europe, based on a 50 Hz power system, with 625 horizontal scan lines and 25 frames per second. SECAM is not compatible with NTSC or PAL, but conversion between the standards is possible.

The original scanning system with which SECAM was used at it's inception was 819/25i, but this system is not thought to be in active use anywhere anymore.
