ABSTRACT:
A caption information receiving apparatus for extracting a caption signal from an input video signal, decoding the digital signal contained in the caption signal and displaying the decoded data on a display screen. A keyboard equipped with keys selects a caption mode and caption information. A caption data memory stores the digital signals. A caption data extractor extracts a digital signal contained in the caption signals. A decoding controller stores the digital signals in the caption data memory and decodes the digital signal read from the caption data memory when an instruction for replaying the caption information is provided. A display controller provides caption information based on the decoded data from the decoding controller and defines a caption display area for displaying the caption information in the caption display area of the display screen.
