Abstract

In a display system according to the present disclosure, a server device includes an authentication processor that authenticates a user for use of a file, based on authentication information of the user input at a user terminal and an access information generator that generates first access information for accessing the file if the user is authenticated by the authentication processor for use of the file, and a display device includes a file acquirer that acquires the file from the server device, based on the first access information generated by the access information generator, and a display processor that displays the file acquired by the file acquirer, on the display.

First claim

1 . A display system comprising:
a mobile terminal of a user; a server device that manages at least one file; and a display device that includes a display, acquires a file of the at least one file from the server device, and displays the file on the display, wherein the mobile terminal includes
a first processor that acquires identification information of the display device by reading an information code displayed on the display, the information code including the identification information of the display device,
the first processor transmits the identification information to the server device, the display device includes
a second processor that acquires, from the server device, access information for accessing the file, and
the second processor displays a download reception screen on the display, and upon receiving, from the user on the download reception screen, an instruction to start downloading the file, acquires the file from the server device based on the access information and displays the file on the display.

2 . The display system according to claim 1 , wherein the server device transmits the access information to the display device corresponding to the identification information acquired from the mobile terminal.

3 . The display system according to claim 2 , wherein the server device stores a plurality of files, generates the access information for accessing a file that has been selected from the plurality of files by the mobile terminal, and transmits the access information thus generated to the display device.

4 . The display system according to claim 1 , wherein upon authenticating the user for use of the file based on authentication information of the user input at the mobile terminal, the server device generates the access information.

5 . The display system according to claim 1 , wherein when, in the server device, the user has been authenticated for use of the file based on authentication information of the user input at the mobile terminal, the second processor generates the information code, and displays the information code on the display.

6 . The display system according to claim 1 , wherein upon acquiring the access information from the server device, the second processor displays the download reception screen on the display.

7 . A display method for displaying a file in a display system including a mobile terminal of a user, a server device that manages the file, and a display device that includes a display, acquires the file from the server device, and displays the file on the display, the display method causing one or more processors to:
in the mobile terminal, acquire identification information of the display device by reading an information code that includes the identification information of the display device, displayed on the display, and transmit the identification information to the server device; and in the display device, acquire, from the server device, access information for accessing the file, display a download reception screen on the display, and upon receiving, from the user on the download reception screen, an instruction to start downloading the file, acquire the file from the server device based on the access information and display the file on the display.

8 . A non-transitory recording medium storing a display program for displaying a file in a display system including a mobile terminal of a user, a server device that manages the file, and a display device that includes a display, acquires the file from the server device, and displays the file on the display, the display program causing one or more processors to:
in the mobile terminal, acquire identification information of the display device by reading an information code that includes the identification information of the display device, displayed on the display, and transmit the identification information to the server device; and in the display device, acquire, from the server device, access information for accessing the file, display a download reception screen on the display, and upon receiving, from the user on the download reception screen, an instruction to start downloading the file, acquire the file from the server device based on the access information and display the file on the display.
