(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. Like PAL, SECAM is based on a 50 Hz power system, but it uses a different encoding process. It has 625 horizontal scan lines and 25 frames per second. SECAM is not compatible with NTSC or PAL, but conversion between the standards is possible.
(There are conflicting reports for SECAM standards. One site says:
It has 625 horizontal scan lines and 25 frames per second.
and another says:
displays 819 lines interlaced at 50 fields per second.
I understand the fields difference, but are the lines the same? I'll go with the 625 lines/25 frames for now.)
