What is different between ...

What is different between "Movie Subtitle" and "Closed Caption" ?
As you can see in some DVDs , they have a subtitle stream, calls Closed Caption. But I didn't get what is the different between them.
Thanks in advance

Subtitles only translate the dialogue, but closed-captions are for people that can't hear at all. So in closed captions they can have additional things like sound effects mentioned.

Well, not exactly. CC is for ntsc televisions and it is stored in text, not pictures.

But every DVDs I see , has those things for the people can't hear. But their name is just subtitle.
