SECAM

SE quential C ouleu A vec M emoire sequential color and memory television standard adopted by France and the USSR in 1967. This has some phase and amplitude integrity (skew-symmetry) advantages over NTSC and some line flicker (Hanover bars) disadvantages. Having France and some parts of Eastern Europe on a different standard than PAL for the rest of Europe and NTSC for North America and Japan is somewhat frustrating for manufacturers of hardware and developers of videotapes.
