High Quality Content by WIKIPEDIA articles! Subtitles are textual versions of the dialog in films and television programs, usually displayed at the bottom of the screen. They can either be a form of written translation of a dialog in a foreign language, or a written rendering of the dialog in the same language, with or without added information to help viewers who are deaf and hard-of-hearing to follow the dialog. Television teletext subtitles, which are hidden unless requested by the viewer from a menu or by selecting the relevant teletext page (e.g. p888), always carry additional sound representations for deaf and hard of hearing viewers.
