Outside broadcasting is like bringing a TV studio to a place that is not a studio. Imagine you are playing in a sports game and you want the whole world to see it. An outside broadcasting team will come with big trucks that have cameras, microphones, and other equipment. They will set all of that up outside and connect it to satellites that let the world watch the game live on TV. It's like magic! It lets people watch all kinds of events that happen outside, like concerts, parades, and even news reports from different places.
