caption

A caption is a descriptive, printed line(s) of text that occasionally appears on the screen, usually at the bottom of the frame, to describe the time, place, or to translate a foreign word/phrase. Different from "closed-captioning" for deaf or hard-of-hearing viewers (closed captions are all white uppercase (capital) letters encased in a black box that require a decoder or television with a decoder chip to be viewed). See also "subtitles."
