SECAM

SECAM (Séquentiel couleur à mémoire) is a television broadcasting system developed in France that transmits color TV signals differently than other systems like PAL or NTSC. It separates the color information into two signals and processes them sequentially (one after the other), rather than simultaneously. This method uses a technique called frequency modulation and stores some color data temporarily for accurate reproduction. Despite being less common today, SECAM was designed for reliable color transmission over circuits with certain technical limitations, contributing to television standards in France, parts of Eastern Europe, and Africa.
