What's African-American in Korean? How's it different from 흑인?

Question today comes from K.B. Ansari about the term "African-American."

I was watching Korean television and I came across someone talking about black culture, hip-hop and so forth. I never knew of a way to say "black" in Korean (other than the color) and always used 아프리카 미국인. To see this other way caught my attention and I wanted to see if it has any other meanings behind it before I started to use it.

Does '흑인' mean anything else? I don't want to start referring to myself and say something degrading. Not to say that I believe it will, but just to be on the safe side.

정말 감사합니다! ^^
