A content detecting device for a digital broadcast signal receiver or a recording apparatus that records the digital broadcast signal. A program-related-information acquiring unit acquires program specific information and information for creating an electronic program guide and causes a memory to store the information. A detecting unit detects a commercial based on information on presence or absence of one of a closed captioning broadcast and a data broadcast and causes the memory to store detection information. A discriminating unit reads out the detection information and outputs a signal for distinguishing the program and the commercial. When information in the program specific information and information in the electronic program guide information in the memory contradict each other concerning presence or absence of one of a closed captioning broadcast and a data broadcast, the detecting unit causes the memory to store information indicating the detection of the commercial. |
