That is, the meta information display control unit 23 controls the display unit 21 so that the display described later is performed on the meta information display screen 50.

  When the meta information display control unit 23 receives the output start notification from the content output control unit 22, the meta information display control unit 23 notifies the meta information distribution unit 12 of the meta information distribution server 3 of the meta information distribution API that specifies the content indicated by the output start notification. A call is made (step S105 in FIG. 3). Then, the meta information display control unit 23 receives meta information such as general information related to the content output by the content output control unit 22 and scene-specific information from the meta information distribution server 3 in the WebSocket method (step of FIG. 3). S106). Further, the meta information display control unit 23 stores the received meta information in the storage unit 24, and displays the meta information on the timeline display area 56 (see FIG. 2) of the meta information display screen 50 of the display unit 21. (Step S107 in FIG. 3). At this time, when the filter mode is off, the scene-specific information included in the meta information is displayed in the timeline display area 56 regardless of the filter parameter, but when the filter mode is on, it is included in the meta information. The scene-specific information extracted as the extracted meta-information (extraction additional information) by the filtering processing unit 16 of the meta-information distribution server 3 is displayed in the timeline display area 56.

  When the meta information display control unit 23 receives the output time change notification from the content output control unit 22, the meta information display control unit 23 synchronizes with the output of the content by the content output control unit 22 and the time line of the meta information display screen 50 of the display unit 21. The display of meta information in the display area 56 (see FIG. 2) is updated. For example, the meta information display control unit 23 acquires the meta information before the reproduction start time of the content indicated by the output time change notification from the storage unit 24, and the time line display area 56 of the meta information display screen 50 of the display unit 21. The acquired meta information is displayed. Also in this case, when the filter mode is on, the scene-specific information extracted as the extracted meta information (extracted additional information) by the filtering processing unit 16 of the meta information distribution server 3 is displayed in the timeline display area 56.

  Further, the meta information display control unit 23 includes a link operation unit (not shown) that instructs the content output control unit 22 to perform output operations such as content reproduction, pause, stop, fast forward, and rewind.
