CLOSED CAPTION FUNCTION
Closed captioning is a process which converts the audio portion of a television program into written
words, which then appear on the television screen in a form similar to subtitles. Closed captions
allow viewers to read the dialogue and narration of television programs.
• Using Closed Captions
Captions
are the subtitles
of the dialogue and narration
of
television programs. For prerecorded programs, program dialogue
can be arranged into captions in advance. It's possible to caption
a live program by using a process called "real-time captioning",
which creates captions instantly. Real-time captioning is normally
done by professional reporters using a machine shorthand system
and computer for translation into English.
Captioning is an effective system for the hearing-impaired,
and it
can also aid in teaching language skills.
