เซกาม

Also known as Séquentiel Couleur à Mémoire

SECAM, also written SÉCAM (, Système Électronique Couleur Avec Mémoire, French for electronic colour system with memory), is an analogue colour television system that was used in France, Russia, and some other countries or territories of Europe and Africa. It was one of three major analog colour television standards, the others being PAL and NTSC. Similar to PAL, a SECAM picture is made up of 625 interlaced lines and displayed at a rate of 25 frames per second (except SECAM-M). However, because of how SECAM processes colour information, it is not compatible with the PAL video format standard.
