Multi-screen display system, display device, ID setting apparatus, and ID setting method
When assigning display IDs to displays which form a multi-screen system, the displays are arranged such that short distance radio communication is possible and an ID setting apparatus which can perform the short distance radio communication is employed. After each display ID is set in the ID setting apparatus, the ID setting apparatus and each of the displays are placed near each other in a contactless manner so as to transfer the display ID set in the ID setting apparatus to the display and assign the display ID to the display.
1. A multi-screen display system that includes a plurality of display devices and an ID setting apparatus, wherein:
the ID setting apparatus comprises:
a generation unit that generates display IDs; and
a first short distance radio communication unit that transmits the display IDs generated by the generation unit to the display devices via short distance radio communication; and
each display device comprises:
a second short distance radio communication unit that receives the relevant display ID from the ID setting apparatus via the short distance radio communication; and a storage unit that stores the received display ID; and
wherein: the ID setting apparatus has an operation unit configured to input a display ID and a camera unit; and
the generation unit generates a display ID according to an operation that is input utilizing the operation unit and another display ID produced utilizing the generated display ID as an initial value and according to whether a relative position between the ID setting apparatus and the display devices moves horizontally or vertically, which is determined based on an image signal captured utilizing the camera unit.
