A closed-caption decoder (often referred to as CaptionVision) displays printed text material that’s derived from the broadcast signal as well as from any captioned videotape or DVD. You may find additional captioned channels for foreign-language translations, statistical displays, secondary analysis during news events, emergency announcements, weather, stock market reports or program listings.
