  • the digital broadcast receiving apparatus 100 is mounted on a vehicle, and the vehicle is running.
  • the first receiving unit 4a receives a broadcast wave of an arbitrary channel being selected, and the display unit 7 and the audio output unit 8 output video and audio of a preceding program of the channel being selected.
  • the storage unit 9 stores preset age information in advance.
  • step ST2a the viewing restriction determination unit 53 detects the switching from the preceding program to the subsequent program on the channel being selected in the first receiving unit 4a.
  • step ST3a the viewing restriction determination unit 53 acquires parental age information of the subsequent program of the selected channel from the program information stored in the storage unit 9. Also, the viewing restriction determination unit 53 determines whether or not the parental age of the subsequent program of the channel being selected exceeds the set age acquired from the storage unit 9. When the parental age of the subsequent program is equal to or lower than the set age, or when the parental age information is not included in the program information of the subsequent program (step ST3a “NO”), the control unit 5b ends the process. At this time, the display unit 7 continues to display the video of the subsequent program, and the audio output unit 8 continues to output the audio of the subsequent program.
  • step ST7 the video / audio mute unit 57 stops the video display of the subsequent program on the display unit 7.
  • the audio output of the subsequent program by the audio output unit 8 is stopped.
  • the control unit 5b executes the processing of step ST5 to step ST6 as in the first embodiment.
  • the digital broadcast receiving apparatus 100 includes the video / audio mute unit 57 that stops the video display of the program by the display unit 7 and the audio output of the program by the audio output unit 8. .
  • the viewing restriction determination unit 53 Based on the program information acquired by the program information acquisition unit 52, the viewing restriction determination unit 53 detects switching from the preceding program to the subsequent program of the selected channel selected by the first receiving unit 4a, Whether the subsequent program is a viewing-restricted program is determined based on the viewing-restricted age information of the subsequent program and the set age information.
  • the video / audio mute unit 57 stops video display and audio output of the subsequent program when it is determined that the subsequent program is a viewing-restricted program.
  • the warning sound generation unit 55 outputs a warning sound when it is determined that the subsequent program is a viewing-restricted program, and the list generation unit 54 displays a list when the subsequent program is determined to be a viewing-restricted program. Is displayed. As a result, when the broadcast of a subsequent program whose viewing is restricted on the channel being received starts, the video and audio output of the subsequent program is stopped and the list is displayed. It can be presented in an easy-to-understand manner to encourage tuning.
  • the viewing restriction determination unit 53 determines whether or not the parental age of the subsequent program of the selected channel exceeds the set age and whether or not the parental age of the program of the selected channel exceeds the set age. It is good also as what determines both.
  • the warning sound generation unit 55 generates a warning sound when the parental age of the subsequent program of the selected channel exceeds the set age and when the parental age of the program of the selected channel exceeds the set age. It may be output.
  • the list generation unit 54 displays the list when the parental age of the subsequent program of the selected channel exceeds the set age, and when the parental age of the program of the selected channel exceeds the set age. It may be displayed.
