ABSTRACT:
A closed caption processing system processes a television signal having caption data therein. A detector receives the television signal. A decoder coupled to the detector receives the television signal, and removes the caption data from the signal to form a stripped video signal and a caption data signal. The stripped video signal is provided to a television. The closed caption data is displayed as text on a screen. A microcontroller receives the caption data from the decoder and provides the caption text to the screen. The caption text is updated unless the microcontroller receives a user selected command for freezing the displayed text. The user enters user selected commands for selecting a portion of the displayed text. A memory stores a dictionary that includes either definitions or translations of text or both. The microcontroller retrieves either the definition or translation of a selected portion of the text responsive to a user request, and then displays the definition or translation.
