Teletext character set

Teletext is a special type of television service that allows people to receive written information on their TV screens. It uses a unique set of characters that are different from the letters and numbers that we normally use to write things down.

Imagine you have an alphabet book with pictures for every letter. The teletext character set is like that, but instead of pictures of things starting with each letter, it has special symbols that stand for different things. For example, there's a symbol that looks like a heart, which means love, and a symbol that looks like a clock, which means time.

Teletext characters are also different from regular letters and numbers because they're made up of only a few pixels or dots. Think of it like a very simple drawing. Each character is like a tiny puzzle made up of little pieces that fit together to make a picture.

When the TV receives a teletext signal, it reads the characters and puts them together to make words and sentences that people can read. It's like putting together a puzzle in your brain!

Overall, the teletext character set is a special type of alphabet with symbols that stand for different things. It's used to send written information to people through the TV, and each character is like a tiny puzzle made up of little dots.
