ITU-R
ITU-R is a special group of people who make rules about how we use technology to talk to each other or watch TV. They make sure that everyone follows the same rules all around the world, so that we can talk to each other and watch TV without any problems.
So imagine you have a toy that you want to use. It's like a walkie-talkie that lets you talk to your friend who is far away. But there are many other kids who also have walkie-talkies and want to talk to their friends. So you need some rules or standards to make sure that everyone can use their walkie-talkies without interfering with each other. That is what ITU-R does for all kinds of technology that we use to communicate with each other.
