Who Provides Closed Captioning?

Closed captioning is text on the TV screen related to the programming being viewed. What you see is an abbreviated version of the actors’ dialogue and indications of important background sounds. For sporting events, closed captioning provides realtime play-by-play descriptions from the announcers. Closed captioning is provided for those requiring assistance understanding and enjoying sound.

Many TVs support closed captioning through the RF and baseband inputs. When your HDTV-to-set-top connection is through the YPrPb port or the DVI port, closed captioning is decoded and displayed by the Explorer set-top.
