Abstract: There is provided a captioned still picture contents producing technique capable of opening caption broadcasting contents being a closed caption and synthesizing it with a still picture obtained from a TV video to automatically produce new captioned still picture contents. In a captioned still picture contents producing system, a captioned video signal generating apparatus generates a captioned video signal, and a still picture contents producing apparatus produces captioned still picture contents from the captioned video signal. The captioned video signal generating apparatus receives the original video signal and caption signal, and generates a control signal based on whether or not the caption is a real time caption. Then, the captioned video signal generating apparatus synthesizes the caption signal and the video signal and inserts the control signal to a predetermined position to generate a captioned video signal.
