Closed Caption Decoded
Closed captions are subtitle-like captions broadcast with many television
shows and recorded with many home rental video movies in the United States
and (usually to a much lesser extent) many other countries in the world.
Closed captions are invisible until decoded by a caption decoder, whether
this decoder is a separate piece of equipment attached to the television set
or is built into the television set itself. Closed caption technology was
first developed to enable deaf and hard of hearing people to watch
television.
