Digital broadcasting

Okay, kiddo! So, you know how we can watch TV shows and movies at home? They get sent to our TVs through special signals that travel through the air. In the old days, these signals were sent using something called analog broadcasting, which is kind of like using a megaphone to yell out a message.

But now, we have something called digital broadcasting, which is like using a special code to send a message that can be read more easily. Think of it like sending a secret message using a special code that only the person who knows the code can understand.

With digital broadcasting, the TV signals are sent as a digital code instead of an analog signal. This makes the picture and sound better and clearer because the code is easier to read and understand. Digital broadcasting also allows more TV channels to be sent at the same time because the code can be compressed to take up less space.

To watch TV shows and movies using digital broadcasting, we need something called a digital receiver, which is like a special decoder that can turn the code back into a picture and sound that we can watch on our TVs.

So that's digital broadcasting, kiddo! It's like using a special code to send TV signals that are clearer and easier to understand, and we need a special decoder to watch it on our TVs. Cool, huh?
