Summary of the Invention

Problems to be Solved by the Invention

[0004] In a conventional digital signage display, when a reading medium is read by a user terminal, all users can access the same content. Therefore, when a reading medium is read by a user terminal, it has been difficult for only a specific user, such as an administrator of the digital signage display, to access specific content.

[0005] An object of the present disclosure is to provide a display system, a display method, and a display program that enable only a specific user to access specific content when a reading medium is read by a user terminal.

Means for Solving the Problems

[0006] A display system according to one aspect of the present disclosure is a system for displaying playback content on a display device. The display system includes: a display processing unit that displays a reading medium on the display device that guides access to the playback content; a communication processing unit that receives terminal identification information transmitted from a user terminal to the display device by short-range wireless communication and establishes the short-range wireless communication between the user terminal, which is authenticated based on the terminal identification information and pre-set authentication information, and the display device; an acquisition processing unit that acquires an access request for the content from the user terminal when the reading medium is read by the user terminal; and a transmission processing unit that transmits access information for the first content to the user terminal when the acquisition processing unit has acquired the access request and the short-range wireless communication between the user terminal and the display device is established.

[0007] A display system according to one aspect of the present disclosure is a system for displaying playback content on a display device. The display system includes: a display processing unit that displays a reading medium on the display device that guides access to the content relating to the playback content; a communication processing unit that receives terminal identification information transmitted from a user terminal to the display device by short-range wireless communication and establishes the short-range wireless communication between the user terminal, which is authenticated based on the terminal identification information and pre-set authentication information, and the display device; an acquisition processing unit that acquires an access request for the content from the user terminal when the reading medium is read by the user terminal; and a transmission processing unit that displays the first content on the display device when the acquisition processing unit has acquired the access request and the short-range wireless communication between the user terminal and the display device is established.

[0008] Another aspect of the present disclosure relates to a display method for displaying playback content on a display device. The display method is a display method in which one or more processors perform the following actions: displaying a reading medium on the display device that guides access to content relating to the playback content; receiving terminal identification information transmitted from a user terminal to the display device by short-range wireless communication and establishing the short-range wireless communication between the user terminal, which is authenticated based on the terminal identification information and pre-set authentication information, and the display device; obtaining an access request for the content from the user terminal when the reading medium is read by the user terminal; and transmitting access information for the first content to the user terminal when the access request has been obtained and the short-range wireless communication between the user terminal and the display device is established.

[0009] A display program according to another aspect of this disclosure is a program that causes a display device to display playback content. The display program is a program that causes one or more processors to perform the following actions: display on the display device a reading medium that guides access to content relating to the playback content; receive terminal identification information transmitted from a user terminal to the display device by near-field wireless communication, and establish the near-field wireless communication between the user terminal, which is authenticated based on the terminal identification information and pre-set authentication information, and the display device; obtain an access request for the content from the user terminal when the reading medium is read by the user terminal; and, when the access request is obtained and the near-field wireless communication between the user terminal and the display device is established, transmit access information for the first content to the user terminal. [Effects of the Invention]

[0010] According to this disclosure, it is possible to provide a display system, display method, and display program that enable specific content to be accessed only by a specific user when a reading medium is read by a user terminal. [Brief explanation of the drawing]

[Figure 2] Figure 2 is a functional block diagram showing the configuration of a display system according to an embodiment of this disclosure. [Figure 3] Figure 3 shows an example of a display screen shown on a user terminal according to an embodiment of this disclosure. [Figure 4] Figure 4 is a flowchart showing an example of the procedure for display processing performed by the display device and user terminal according to the embodiment of this disclosure. [Figure 5] Figure 5 is a schematic diagram showing the general configuration of a display system according to another embodiment of the present disclosure. [Modes for carrying out the invention]

[0012] The embodiments of this disclosure will be described below with reference to the attached drawings. Note that the following embodiments are merely examples of the embodiments of this disclosure and do not limit the technical scope of this disclosure.

[0013] The display system relating to this disclosure is a system for displaying content on a display device. Specifically, the display system plays predetermined distributed content on a digital signage display (display device) according to a predetermined playback schedule (playlist), and when a two-dimensional code displayed on the digital signage display is read by a user terminal, it displays specific content on the user terminal.

[0014] The aforementioned digital signage display displays (plays) content consisting of video and audio, such as advertisements, in various locations such as public squares, train stations, streets, offices, and shops.

[0015] Figure 1 is a schematic diagram showing the general configuration of the display system 10 according to this embodiment. The display system 10 includes a display device 1 corresponding to a digital signage display and a user terminal 2 for a user who views the digital signage display. The display device 1 and the user terminal 2 are connected to communicate via two types of networks: a short-range communication network N1 and a network N2 such as the internet. Network N1 is a short-range wireless communication network such as Bluetooth® or beacons. Network N2 is a communication network such as the internet that can be accessed by a browser.

[0016] Furthermore, the display system 10 may include a plurality of display devices 1 and a plurality of user terminals 2. In this embodiment, the display system 10 including the display devices 1 and user terminals 2 corresponds to the display system of this disclosure, but the display system of this disclosure may consist of a single display device 1.

[0017] [Display device 1] As shown in Figure 1, the display device 1 is a display device (digital signage display) that includes a control unit 11, a storage unit 12, an operation display unit 13, and a communication unit 14, etc.

[0018] The communication unit 14 is a communication interface for connecting the display device 1 to networks N1 and N2 by wire or wireless connection, and for performing data communication with the user terminal 2 via networks N1 and N2 in accordance with a predetermined communication protocol. For example, the communication unit 14 has a function to perform Bluetooth communication for communication on network N1, and connects with the user terminal 2 via short-range wireless communication by performing a pairing process with the user terminal 2. The communication unit 14 also has a function to perform Internet communication for communication on network N2, and accepts access from the user terminal 2 via the Internet.

[0019] The operation display unit 13 is a user interface including a display unit such as a liquid crystal display or an organic EL display for displaying various types of information, and an operation unit such as a mouse, a keyboard, or a touch panel for receiving operations.

[0020] The storage unit 12 is a non-volatile storage unit such as an HDD (Hard Disk Drive), an SSD (Solid State Drive), or a flash memory for storing various types of information. In the storage unit 12, control programs such as a display program for causing the control unit 11 to execute the display process (see FIG. 4) described later are stored. For example, the display program is non-temporarily recorded on a computer-readable recording medium such as a CD or a DVD, and is read by a reading device (not shown) such as a CD drive or a DVD drive provided in the display device 1 and stored in the storage unit 12. Note that the display program may be distributed from a cloud server and stored in the storage unit 12.

[0021] In addition, in the storage unit 12, in addition to the content data of the playback content, various types of information related to the content are stored. Specifically, in the storage unit 12, data such as a playlist related to the playback schedule of the content and setting information of various items related to the playback of the content are stored.

[0022] Furthermore, the storage unit 12 stores data for a general user-facing page (e.g., advertising page 121) that can be viewed by general users, and data for an administrator-facing page (e.g., administrator page 122) that can be viewed by the administrator of the display device 1 (e.g., content administrator). The administrator can register content, create playlists, set playback schedules, and issue playback instructions for content on the administrator page 122. In other words, the administrator page 122 is a management page that accepts setting operations for the display device 1. Users who can access the administrator page 122 are limited to the aforementioned administrator, and the administrator's information (such as authentication information) may be registered in advance. The administrator page (administrator page 122) is an example of the first content of this disclosure, and the general user-facing page (advertising page 121) is an example of the second content of this disclosure.

[0023] Furthermore, the memory unit 12 stores data for accessing the advertisement page 121 (advertisement page URL (Uniform Resource Locator)) and data for accessing the administrator page 122 (administrator page URL).

[0024] In another embodiment, some or all of the aforementioned data may be stored in a server (data server) accessible from the display device 1. In this case, the control unit 11 of the display device 1 may acquire the information from the server and execute the respective processes.

[0025] The control unit 11 includes control devices such as a CPU, ROM, and RAM. The CPU is a processor that performs various arithmetic operations. The ROM is a non-volatile memory unit in which control programs such as a BIOS and OS are pre-stored to cause the CPU to perform various operations. The RAM is a volatile or non-volatile memory unit that stores various information and is used as a temporary memory (work area) for the various operations performed by the CPU. The control unit 11 controls the display device 1 by executing various control programs pre-stored in the ROM or memory unit 12 using the CPU.

[0026] Specifically, the control unit 11 includes various processing units such as a display processing unit 111, a communication processing unit 112, an acquisition processing unit 113, and a transmission processing unit 114. The control unit 11 functions as these various processing units by executing various processes according to the display program. Some or all of the processing units included in the control unit 11 may be composed of electronic circuits. The display program may be a program that causes multiple processors to function as these various processing units.

[0027] The display processing unit 111 causes the operation display unit 13 to display content. For example, the display processing unit 111 causes the operation display unit 13 to display pre-registered playback content according to a pre-set playback schedule and playlist.

[0028] Furthermore, the display processing unit 111 displays a reading medium on the operation display unit 13 that guides the user to access content related to the playback content (a web page related to the playback content) to be displayed on the operation display unit 13. The web page is a page for general users, for example, an advertising page 121 (second content). The advertising page 121 is a web page that contains information about advertisements for the playback content. The reading medium is a two-dimensional code image, and the two-dimensional code image is displayed on the operation display unit 13 (see Figure 3). The reading medium is not limited to a two-dimensional code, but may be various identification codes, identification markers, etc.

[0029] In another embodiment, the reading medium may be a paper medium on which a two-dimensional code is printed. The paper medium may be attached to the housing of the display device 1 or placed in the vicinity of the display device 1.

[0030] The two-dimensional code is readable by the camera 24 of the user terminal 2, and the camera 24 reads the information contained in the two-dimensional code (access information for the advertisement page 121 (advertisement page URL)).

[0031] The communication processing unit 112 receives terminal identification information transmitted from the user terminal 2 to the display device 1 via short-range wireless communication (e.g., Bluetooth), and establishes a short-range wireless communication connection between the user terminal 2 and the display device 1 (communication unit 14) based on the terminal identification information and pre-configured authentication information. In other words, the communication processing unit 112 performs the pairing process between the user terminal 2 and the display device 1. The authentication information is, for example, information (terminal identification information) registered as an administrator terminal owned by a user who is permitted to access the administrator page 122, i.e., an administrator who has the authority to perform operations such as registering content, creating playlists, setting playback schedules, and instructing content playback.

[0032] Furthermore, the communication processing unit 112 may store the terminal identification information of the user terminal 2 paired with the display device 1 in the storage unit 12. This allows the display device 1 and the user terminal 2 to connect when they are in close proximity.

[0033] The acquisition processing unit 113 obtains a request for access to content (first access request) from the user terminal 2 when the two-dimensional code (reading medium) displayed on the display device 1 is read by the user terminal 2. For example, when the camera 24 of the user terminal 2 reads the two-dimensional code, the user terminal 2 accesses the advertisement page URL contained in the two-dimensional code. As a result, the acquisition processing unit 113 obtains a first access request for the advertisement page 121 from the user terminal 2.

[0034] The transmission processing unit 114 transmits access information (administrator page URL) to the administrator page 122 to the user terminal 2. For example, if the acquisition processing unit 113 acquires the first access request for content (e.g., advertising page 121) from the user terminal 2, and the short-range wireless communication between the user terminal 2 and the display device 1 (communication unit 14) is connected (paired), the transmission processing unit 114 transmits the administrator page URL to the user terminal 2. The transmission processing unit 114 also transmits the administrator page URL to the user terminal 2 using the short-range wireless communication (Bluetooth communication).

[0035] When user terminal 2 obtains the administrator page URL from display device 1, it displays the administrator page URL. When the user selects the administrator page URL, the acquisition processing unit 113 obtains an access request (second access request) for administrator page 122 (first content) from user terminal 2.

[0036] As described above, for example, when playback content is displayed on the display device 1, the camera 24 of the user terminal 2 reads the two-dimensional code and the acquisition processing unit 113 obtains a first access request to the advertising page 121 from the user terminal 2. If the user terminal 2 and the display device 1 are already paired (i.e., the user terminal 2 is an authenticated administrator terminal), the transmission processing unit 114 sends the administrator page URL of the administrator page 122 to the user terminal 2. As a result, the administrator page URL is displayed on the user terminal 2 when the user selects it (see Figure 3).

[0037] In contrast, if user terminal 2 and display device 1 are not paired (i.e., user terminal 2 is an unauthenticated general user terminal), the transmission processing unit 114 does not send the administrator page URL to user terminal 2. As a result, the administrator page URL is not displayed on user terminal 2, and the display of the advertisement page 121 is maintained (see Figure 3).

[0038] The display system of this disclosure may be configured to include the display processing unit 111, communication processing unit 112, acquisition processing unit 113, and transmission processing unit 114 described above. In other words, the display system of this disclosure may consist of a display device 1 alone.

[0039] [User Terminal 2] As shown in Figure 2, the user terminal 2 includes a control unit 21, a storage unit 22, an operation display unit 23, a camera 24, and a communication unit 25, etc. The user terminal 2 is an information processing device such as a mobile phone, smartphone, tablet terminal, or personal computer.

[0040] The communication unit 25 is a communication interface for connecting the user terminal 2 to networks N1 and N2 by wire or wireless connection, and for performing data communication with the display device 1 via networks N1 and N2 in accordance with a predetermined communication protocol. For example, the communication unit 25 has a function for performing Bluetooth communication for communication on network N1, and connects to the display device 1 via short-range wireless communication by performing a pairing process with the display device 1. The communication unit 25 also has a function for performing Internet communication for communication on network N2, and accesses the display device 1 via the Internet.

[0041] Camera 24 is a digital camera that captures an image of the subject, a two-dimensional code (reading medium), and outputs it as digital image data. The image data captured by camera 24 is transmitted to control unit 21. For example, the user reads the two-dimensional code image displayed (or posted) on display device 1 with camera 24 (see Figure 3). The control unit 21 obtains access information (advertising page URL) for the advertising page 121 from the image data.

[0042] The operation display unit 23 is a user interface comprising a display unit such as a liquid crystal display or an organic EL display that displays information such as various web pages, and an operation unit such as a mouse, keyboard, or touch panel that accepts input.

[0043] The storage unit 22 is a non-volatile storage unit such as an HDD, SSD, or flash memory that stores various types of information. For example, the storage unit 22 stores a control program such as a browser program. Specifically, the browser program is a control program that causes the control unit 21 to execute communication processing with an external device such as the display device 1 according to a communication protocol such as HTTP (Hypertext Transfer Protocol). Alternatively, the browser program may be a dedicated application for executing communication processing with the display device 1 according to a predetermined communication protocol.

[0044] The control unit 21 includes control devices such as a CPU, ROM, and RAM. The CPU is a processor that performs various arithmetic operations. The ROM is a non-volatile memory unit that stores control programs such as a BIOS and OS in advance to allow the CPU to perform various operations. The RAM is a volatile or non-volatile memory unit that stores various information and is used as a temporary memory (work area) for the various operations performed by the CPU. The control unit 21 controls the user terminal 2 by executing various control programs that are pre-stored in the ROM or memory unit 22 using the CPU.

[0045] Specifically, the control unit 21 functions as a browser processing unit 211 by executing various processes according to the browser program stored in the storage unit 22. The browser processing unit 211 can display web pages provided from the display device 1 via the network N2 on the operation display unit 23 and perform browser processing to input operations on the operation display unit 23 to the display device 1. In other words, the user terminal 2 can function as an operation terminal for the display device 1 by the execution of the browser program by the control unit 21. Note that some or all of the processing units included in the control unit 21 may be composed of electronic circuits.

[0046] For example, the control unit 21 acquires data from a web page (such as an advertising page 121 or an administrator page 122) from the display device 1 and displays the web page on the operation display unit 23. Furthermore, if a dedicated application corresponding to the display device 1 is installed on the user terminal 2, the user of the user terminal 2 will launch the dedicated application, and the web page will be displayed on the operation display unit 23.

[0047] For example, when a user scans a QR code with camera 24 (see Figure 3), the control unit 21 displays the advertisement page 121 on the user terminal 2. Also, if a user scans a QR code with camera 24 and the user terminal 2 is already paired with the display device 1, the control unit 21 displays the administrator page 122 on the user terminal 2. In this way, when a regular user scans a QR code with user terminal 2, the advertisement page 121 is displayed on user terminal 2, and when an administrator with predetermined operational authority regarding the content scans a QR code with user terminal 2, the administrator page 122 is displayed on user terminal 2.

[0048] [Display Processing] The following describes an example of the display processing procedure performed by the display system 10, with reference to Figure 4.

[0049] This disclosure can be understood as an invention of a display method that performs one or more steps included in the display process. Furthermore, one or more steps included in the display process described herein may be omitted as appropriate. In addition, the execution order of each step in the display process may differ to the extent that similar effects are produced. Furthermore, although this description uses the case in which the control unit 11 of the display device 1 and the control unit 21 of the user terminal 2 perform each step in the display process as an example, in other embodiments, multiple processors may distribute and execute each step in the display process.

[0050] Here, it is assumed that the display device 1 displays pre-registered playback content according to a pre-set playback schedule and playlist (see Figure 3). Furthermore, it is assumed that the display device 1 displays a two-dimensional code image. The display device 1 may also display a two-dimensional code image when it detects a person nearby, or when playing specific playback content.

[0051] <Step S1> In step S1, the control unit 11 of the display device 1 causes the operation display unit 13 to display a two-dimensional code image. For example, the control unit 11 plays the content to be played and also displays a two-dimensional code image (two-dimensional code image) that includes access information (advertisement page URL) for accessing the advertisement page 121 related to the advertisement for the content to be played (see Figure 3).

[0052] <Step S2> In step S2, the control unit 21 of the user terminal 2 reads the two-dimensional code using the camera 24. For example, when the user captures a two-dimensional code image with the camera 24 of the user terminal 2, the control unit 21 reads the two-dimensional code image. The control unit 21 also obtains the advertisement page URL from the two-dimensional code.

[0053] <Step S3> In step S3, the control unit 21 of the user terminal 2 accesses the advertisement page URL via the internet. Specifically, the control unit 21 sends an access request (first access request) to the display device 1 for the advertisement page 121.

[0054] The control unit 21 may automatically send a first access request to the advertising page 121 to the display device 1 when it reads the two-dimensional code image, or it may send a first access request to the advertising page 121 to the display device 1 when the user selects the advertising page URL displayed on the user terminal 2 after reading the two-dimensional code image.

[0055] <Step S4> In step S4, when the control unit 11 of the display device 1 receives an access request (first access request) for the advertisement page 121 from the user terminal 2, it transmits the advertisement page 121 to the user terminal 2 via the internet.

[0056] <Step S5> In step S5, the control unit 21 of the user terminal 2 displays the advertisement page 121 on the operation display unit 23 of the user terminal 2 (see Figure 3). Here, the control unit 21 displays the advertisement page 121 corresponding to the QR code, regardless of the user's attributes (general user, administrator, etc.).

[0057] <Step S6> In step S6, the control unit 11 of the display device 1 determines whether the user terminal 2 paired with the display device 1 is nearby (i.e., can communicate via short-range communication). If the control unit 11 determines that the paired user terminal 2 is nearby (S6: Yes), it proceeds to step S7. On the other hand, if the control unit 11 determines that the paired user terminal 2 is not nearby (S6: No), it returns to step S1.

[0058] <Step S7> In step S7, the control unit 11 of the display device 1 transmits the URL of the administrator page 122 (administrator page URL) to the user terminal 2 via Bluetooth. Specifically, the control unit 11 transmits the administrator page URL to the user terminal 2 which is paired with the display device 1.

[0059] <Step S8> In step S8, when the control unit 21 of the user terminal 2 obtains the administrator page URL, it accesses the administrator page URL via the internet. Specifically, the control unit 21 sends an access request (second access request) to the display device 1 for the administrator page 122. The control unit 21 may automatically send the second access request to the administrator page 122 to the display device 1 when it obtains the administrator page URL, or it may send the second access request to the administrator page 122 to the display device 1 when the user selects the administrator page URL displayed on the user terminal 2 after obtaining the administrator page URL.

[0060] <Step S9> In step S9, when the control unit 11 of the display device 1 receives an access request (second access request) for the administrator page 122 from the user terminal 2, it transmits the administrator page 122 to the user terminal 2 via the internet.

[0061] <Step S10> In step S10, the control unit 21 of the user terminal 2 displays the administrator page 122 on the operation display unit 23 of the user terminal 2 (see Figure 3). For example, the control unit 21 displays the administrator page 122, which accepts operations such as content registration, playlist creation, playback schedule setting, and content playback instruction. When the user performs the above operations on the administrator page 122, the control unit 11 of the display device 1 executes, for example, content registration processing, playlist creation processing, and playback schedule setting processing in response to the operation. After step S10, the control unit 21 moves the process to step S2.

[0062] As described above, the display device 1 and the user terminal 2 execute the display process. Furthermore, the display device 1 and the user terminal 2 execute the above process each time the two-dimensional code displayed on the display device 1 is read by the user terminal 2.

[0063] As described above, the display system 10 is a system that displays playback content on the display device 1. The display system 10 displays a reading medium (e.g., a two-dimensional code) on the display device 1 that guides the user to access content related to the playback content (e.g., an advertising page 121). The display system 10 also receives terminal identification information transmitted from the user terminal 2 to the display device 1 via short-range wireless communication (e.g., Bluetooth communication), and establishes a short-range wireless communication connection between the user terminal 2 and the display device 1, which are authenticated based on the terminal identification information and pre-set authentication information. Furthermore, when the reading medium is read by the user terminal 2, the display system 10 obtains a first access request for the content from the user terminal 2. Furthermore, when the display system 10 obtains the first access request and communication (short-range wireless communication) is established between the user terminal 2 and the display device 1, it transmits access information to the first content (administrator page 122) to the user terminal 2.

[0064] Furthermore, if the display system 10 obtains the first access request and short-range wireless communication is not established between the user terminal 2 and the display device 1, it does not send access information to the first content (administrator page 122) to the user terminal 2.

[0065] According to the above configuration, when a reading medium corresponding to the display device 1 is read by the user terminal 2, it is possible to grant access to specific content (administrator page 122) only to specific users. For example, access to the administrator page 122 can be permitted only to the administrator of the display device 1, while general users are prohibited from accessing the administrator page 122.

[0066] The control unit 11 may also set a one-time password for the administrator page URL of the administrator page 122. This will cause the administrator page 122 to be displayed on the user terminal 2 if the user enters the predetermined password within a predetermined time.

[0067] In another embodiment of this disclosure, the control unit 11 of the display device 1 may display the first content (administrator page 122) on the display device 1 when the acquisition processing unit 113 acquires a first access request from the user terminal 2 and short-range wireless communication is established between the user terminal 2 and the display device 1. That is, the control unit 11 may omit the process of displaying the access information (administrator page URL) for the administrator page 122 on the user terminal 2 and the process of displaying the administrator page 122 on the user terminal 2, and instead display the administrator page 122 on the display device 1. This allows a user (in this case, an administrator) who is near the display device 1 to view the administrator page 122 on the display device 1.

[0068] Furthermore, the control unit 11 is configured such that if the acquisition processing unit 113 acquires a first access request from the user terminal 2 and short-range wireless communication is not established between the user terminal 2 and the display device 1, the administrator page 122 is not displayed on the display device 1. This ensures that users in the vicinity of the display device 1 (in this case, general users) cannot access the administrator page 122 on the display device 1, thereby ensuring security regarding the administrator page 122.

[0069] In the above-described embodiment, the display device 1 manages each web page (advertising page 121, administrator page 122, etc.). However, in other embodiments, each web page may be managed by a device other than the display device 1. For example, as shown in Figure 5, the display system 10 may consist of the display device 1, a user terminal 2, and a server 3. In this case, the server 3 receives access requests from the user terminal 2 and displays each web page on the user terminal 2. Alternatively, when the server 3 receives an access request from the user terminal 2, it may send an access notification to the display device 1, and the display device 1 may determine whether or not to send the administrator page 122.
