  In step S12, the broadcast / communication cooperation service execution unit 192 sends display information indicating that the communication video is not being displayed to the presentation processing unit 193. Subsequently, in step S13, the presentation processing unit 193 generates icon video data indicating that the video based on the communication content is not displayed on the display unit 170. Then, the presentation processing unit 193 generates communication information video data CDT from the icon video data and the information video data of the current cumulative communication data amount of the communication terminal 210 in the current month, and sends it to the display unit 170. Thereafter, the process returns to step S11.

  On the other hand, if the result of the determination in step S11 is positive (step S11: Y), the process proceeds to step S14. In step S14, the broadcast / communication cooperation service execution unit 192 sends display information indicating that the communication video is being displayed to the presentation processing unit 193. Thereafter, the processing proceeds to step S15.

  In step S15, the presentation processing unit 193 generates icon video data indicating that the video based on the communication content is displayed on the display unit 170. Then, the presentation processing unit 193 generates communication information video data CDT from the icon video data and the information video data of the current cumulative communication data amount of the communication terminal 210 in the current month, and sends it to the display unit 170. Thereafter, the process returns to step S11.

Then, the presentation processing unit 193 generates communication information video data CDT indicating that a video based on the communication content is not displayed on the display unit 170, and sends the generated data to the display unit 170.

  Therefore, when the display designation of the video based on the communication content is the same as the operation of the video display designation based on the data broadcast, the user is asked if the video currently displayed is based on the communication content. You can let them know.

  Further, in the present embodiment, regardless of whether or not the video based on the communication content is displayed on the display unit 170, the accumulated communication data amount of the communication terminal 210 from the beginning of the month to the present is presented to the user. For this reason, information for avoiding the use restriction of the mobile communication can be provided to the user, and the convenience of the user can be improved.
