SECAM (Sequential Couleur avec Mémoire)

The international standard for transmitting video signals from France, also used in the Russia.  Higher resolution than NTSC. Sequential Couleur avec Mémoire. A television standard closely related to PAL but with a different method of sending color information. SECAM uses the same resolution as PAL (625 lines) but transmits the color information sequentially: R-Y on one line and B-Y on the next.  Runs at 625 horizontal lines of resolution updating 25 frames a second.

The standard video formats are NTSC, PAL, and SECAM. Many projectors accept all three. These systems deliver 576 lines of video per frame, rather than the 480 lines per frame of NTSC. So in this environment, the 1024x576 resolution projector is the ideal solution for DVD and standard definition video. Indeed, Texas Instruments dubbed their 1024x576 DLP chip the "Matterhorn" because of its unique applicability in the European market where PAL and SECAM are established standards.
