A remote control device for a TV can be used to select a word in a closed caption text, and if the word is associated with additional content, a list of the content is displayed on the TV. The user can select a piece of content from the list. A dictionary meaning of a selected word may also or alternatively be provided. Alternatively, only a subset of closed captioning words need be shown to the viewer, or the presented words may be defined by the content provider independently of closed captioning text. |
