So you know how sometimes when we watch TV shows or movies from different countries they look a bit different? That's because different parts of the world use different "standards" for how to show pictures on TV.
For example, in the United States, they use a standard called NTSC, but in Europe they use one called PAL. This means that if a TV show is made in the United States and then shown on a TV in Europe, it might look different because the picture is being shown in a different way.
To fix this problem, we have something called "television standards conversion." This is like a translator for TV shows - it helps make sure that the picture looks the same no matter where it is being shown.
So if we want to show a TV show made in the United States on a TV in Europe, we use a machine called a standards converter. The standards converter takes the picture from the show and changes it so that the TV in Europe can show it in the PAL standard. This way, the picture will look the same as if it was made in Europe.
So that's television standards conversion - it's like a translator for TV pictures to make sure they look the same no matter where they are being shown.
