A tiling display apparatus includes a plurality of display modules connected to one another through a first interface circuit and a second interface circuit and a set board receiving a defect occurrence and position signal, generated in a broken-down module of the plurality of display modules, from the broken module through the first interface circuit in a first period, generating a defect recognition completion signal in a second period succeeding the first period, and transferring the defect recognition completion signal to the broken-down module through the second interface circuit in the second period.

A content display method executed by a distribution device communicatively connected to a plurality of display devices and configured to distribute a content to the plurality of display devices. A failure display device, in which a failure has occurred, is detected from among the plurality of display devices. A replacement display device is extracted from one or more non-failure display devices, in which any failure has not been detected. The one or more non-failure display devices are included in the plurality of display devices. The extraction is made on the basis of the degree of similarity in display condition between the one or more non-failure display devices and the failure display device. A content, which had once been assigned to be displayed on the failure display device, is transmitted toward the replacement display device as extracted, and to allow the replacement display device to display the content.
