May be configured to execute.

[Display control operation]
Next, the display control operation of the present embodiment will be described with reference to the flowcharts of FIGS.

  First, the host system 14 generates a video display information 140A by processing a live video of a race from, for example, a camera installed in a public stadium. The image composition device 13 outputs the video display image to the LED controller 12A. The LED controller 12 </ b> A displays a video corresponding to the video display information 140 </ b> A on the video display unit 10 </ b> A of the display device 10 based on the video display image output from the image synthesis device 13.

  In this case, the screen size of the video display unit 10 </ b> A is preset by the image composition device 13. Here, confirmation information (character information) such as the race arrival order is not yet displayed on the character display portion 10B whose position is set in advance on the display screen.

  Next, the host system 14 generates the character display information 140B when collecting finalized information (character information) such as the race arrival order from the information collecting device (terminal device) installed in the public stadium. That is, the host system 14 generates the video display information 140A and the character display information 140B, and outputs them to the image composition device 13 (step S1). The image synthesizing device 13 synthesizes the video display information 140A and the character display information 140B as one display image, further divides the synthesized one display image into a video display image and a character display image, and outputs them to the LED controllers 12A and 12B. (Step S2).

  By the display operation of the LED controllers 12A and 12B, as shown in FIG. 1, video and character information (determined information such as race arrival order) is displayed on the display screen of the display device 10 (step S3). That is, the video corresponding to the video display information 140A is displayed on the video display unit 10A. In addition, character information (determined information such as race order) corresponding to the character display information 140B is displayed on the character display portion 10B. Such a display process continues until the race of the public stadium is completed (step S6). The display content of the display screen of the display device 10 changes according to the update of the video display information 140A and the character display information 140B.

  A description will be given of the control particularly when a failure occurs in the character display unit 10B during the above display process (YES in step S4). Conventionally, an exchange operation is performed for each display tile constituting the character display unit 10B. For this reason, the display process of the character display part 10B will be interrupted. The present embodiment is configured to maintain the display of the character display unit 10B without performing such replacement work.

  Here, both the video display unit 10A and the character display unit 10B can be exchanged in units of display tiles. Usually, the display tile has a size of about 400 mm in width and about 200 mm in length. The character display unit 10B is composed of, for example, 32 display units. The display unit is composed of a plurality of display tiles.

  Therefore, the computer 15 executes control to change the position of the character display unit 10B via the image composition device 13 (step S5). Specifically, as shown in FIG. 2, the position of the character display unit 10B is changed from the screen area 10C including the failed part to the area of the video display unit 10A. Further, the computer 15 changes the screen size of the video display unit 10A to be reduced as the position of the character display unit 10B is changed. Further, as shown in FIG. 3, the positions of the video display unit 10A and the character display unit 10B can be exchanged.

  As described above, according to the present embodiment, in the system that synthesizes the video such as the actual race video and the character information (determined information) such as the race arrival order and displays it on the large display screen, the character display unit 10B is displayed. When a failure occurs in the constituent display units, the position of the character display unit 10B on the display screen is changed. At the same time, the screen size (view angle) of the video display unit 10A is reduced. Therefore, it is possible to maintain the display of character information (determined information) such as the race arrival order on the character display unit 10B without replacing the failed display tile. The repair work for exchanging the defective display tile may be performed after the race is finished, for example.

  Thereby, when a part of the large display screen breaks down, it is possible to avoid a trouble in operation of the large image display device that causes an interruption of an important display accompanying the repair work. Here, when the position of the character display unit 10B on the display screen is changed, the output of the video signal to the LED controllers 12A and 12B is temporarily stopped in practice, so that the display of the large display screen is interrupted. Become. However, since the interruption time is short, there is no problem in operation of the large-sized video display device. Here, even if the screen size of the video display unit 10A is reduced, there is no operational problem.

  This embodiment is particularly effective in the following situation.

  There are cases where the operation of replacing the broken display tile is possible in about 5 minutes, for example. In this case, since it is assumed that the failure part has a great influence on the character display, it is effective as a connection for maintaining the character display until the replacement of the display tile. Note that the exchange work can be performed, for example, between races.

  The display unit that constitutes the character display unit 10B is composed of, for example, about 32 display tiles. In this case, a power source is provided for each display unit. When a power failure occurs, it is expected that the entire display of the character display unit 10B will disappear. It is effective as a countermeasure in such a case. The power supply of the video display unit 10A and the character display unit 10B is divided into systems, but is particularly effective when the power display system of the character display unit 10B fails.

  In the present embodiment, the failure detection of the large display screen may be performed by a method realized by the failure detection device 11 provided in the conventional display device 10 or another method. As a specific example, the computer 15 changes the screen size of the video display unit 10 </ b> A and the position of the character display unit 10 </ b> B when receiving the display screen failure detection signal 110 from the failure detection device 11 provided in the display device 10. Execute control to Further, the computer 15 executes control to change the screen size of the video display unit 10A and the position of the character display unit 10B via the image composition device 13 in accordance with the screen display pattern switching control signal from the host system 14. Also good.

  As shown in FIG. 4, the host system 14 may output a screen display pattern switching control signal to the computer 15 based on information notifying the failure of the display screen from the computer 15. In this case, as shown in FIG. 4, a camera 20 for failure detection is installed to monitor the display state of the character display unit 10B. The computer 15 inputs the image captured by the camera 20 and displays the display characters of the character display unit 10 </ b> B on the display 17. The worker confirms a partial failure of the character display unit 10B by visual observation on the display 17. The operator notifies the host system 14 of the failure confirmation result of the character display unit 10B by operating the operation unit 16.
