SECAM

SECAM is a way that colors are shown on TVs. You know how your TV shows different colors when you watch it? Well, that's because of a system called "color encoding". SECAM is one of those systems, just like PAL or NTSC (these are other types of color systems).

When you watch TV, the picture is made up of tiny dots called pixels. Each pixel can be a different color, and if you put all the pixels together, you get the whole picture. SECAM works by telling each one of those tiny pixels what color it should be. It does this by sending signals through the TV cables that connect your TV to the broadcasting station.

The way that SECAM does this is a little bit different than some of the other color systems. Instead of sending all the colors at once, it sends the colors in a sequence. This means that it takes a little bit longer for SECAM to show you the whole picture, but it also means that it doesn't need as much bandwidth (which is like the amount of space on the TV signal for color information) as some other color systems.

So, to summarize, SECAM is a way that colors are shown on TVs. It uses a system called "color encoding" to tell each pixel on the TV what color it should be. SECAM sends the colors in a sequence, which takes a little bit longer but also doesn't require as much space on the TV signal.
