(Embodiment 1)
<System configuration>
FIG. 1 is a diagram showing an overview of a configuration example of a display system 10 according to Embodiment 1. As shown in FIG. As shown in FIG. 1 , the display system 10 has a plurality of wireless terminals (smartphones, tablet terminals, etc.) 101 , display devices (televisions, personal computers, etc.) 105 , a content server 104 , and a remote controller 103 . Each wireless terminal 101, content server 104, and display device 105 are connected by wireless communication (WiFi (registered trademark) (Wireless Fidelity) 102, various wireless LANs (Local Area Networks) such as IEEE.11x, and NFC (Near Field Communication). ), Bluetooth (registered trademark), wired LAN, etc.). Also, the remote control 103 is connected to the display device 105 via a network (wireless communication).

The content server 104 is a server system that distributes content (for example, viewing data for viewing video (video), applications for playing games, image data for viewing books, etc.) in an Internet environment. is. Content includes first content that cannot be obtained unless a predetermined condition is met (for example, content that is prohibited for users under the age of 18 from viewing or content that cannot be viewed without charging). In addition, there is a second content that can be freely obtained without clearing a predetermined condition. Various contents acquired by each wireless terminal 101 and the display device 105 can be viewed on the display device 105 by setting the environment as shown in FIG.

Each wireless terminal 101 can be connected to the content server 104 without using the display device 105 . Also, each wireless terminal 101 instructs the display device 105 to acquire content. The display device 105 instructed to acquire the content acquires the content from the content server 104 . As a result, since the display device 105 actually acquires the content, the wireless terminals 101 are not burdened with processing when acquiring the content.

A dedicated application (an application for enabling the wireless terminal 101 to be used as a remote controller for the display device 105) is downloaded to each wireless terminal 101 in advance. After the dedicated application of the wireless terminal 101 is executed, the wireless terminal 101 receives inputs of an SSID (Service Set Identifier), a password, and a display mode of the display device 105, which will be described later. This allows the wireless terminal 101 to connect to the display device 105 via the wireless communication 102 and communicate with the display device 105 . Then, wireless terminal 101 can operate display device 105 as a remote controller.

Here, display modes of the display device 105 include a full access mode and a browsing mode. When the full access mode is set, the display device 105 displays a first display screen (described later in FIG. 3) that receives an input for obtaining the first content and an input for obtaining the second content. (a), (c)) are displayed. On the other hand, when the viewing mode is set, the display device 105 does not accept input for acquiring the first content, and displays a second display screen (described below) that accepts input for acquiring the second content. FIG. 3(b)) is displayed.

When a first wireless terminal (hereinafter sometimes referred to as a parent terminal) having the right to acquire the first content from the content server 104 is connected, the display mode of the display device 105 is set to full access mode. be done. On the other hand, when the parent terminal is not connected and a second wireless terminal (hereinafter sometimes referred to as a child terminal) that does not have the authority to acquire the first content from the content server 104 is connected. , the display mode of the display device 105 is set to the viewing mode.

After the dedicated application of the wireless terminal 101 is executed, each wireless terminal 101 accepts the input of the SSID, password, and display mode, thereby identifying the wireless terminals 101 under the control of the display device 105. A display mode for each ID is registered in the display device 105 . Here, the wireless terminal ID for identifying the wireless terminal 101 is the IP (Internet Protocol) address of the wireless terminal or the like. Note that the input of the wireless terminal ID may be accepted from the user.

The wireless terminal 101 transmits the received wireless terminal ID and display mode to the display device 105 . After that, the display device 105 stores the wireless terminal ID transmitted from the wireless terminal 101 and the display mode in association with each other. Thereby, the display mode for each wireless terminal ID for identifying the wireless terminal is registered in the display device 105 .

For example, in the home, the display device 105 installed at home registers the wireless terminal ID and display mode (full access mode) of the wireless terminal 101 owned by the parents, and displays the wireless terminal 101 owned by the child. A terminal ID and a display mode (viewing mode) are registered.

Wireless terminal 101 accepts an input for displaying content stored therein on display device 105 . Upon receiving an input for displaying content, the wireless terminal 101 receives a URL (Uniform Resource Locator) for specifying the location where the content exists, account information (telephone number and password) of the wireless terminal 101, and information on the content. A request signal containing the purchase history is sent to the display device 105 .

The display device 105 acquires content by accessing the URL included in the request signal transmitted from the wireless terminal 101, and displays (plays back) the acquired content. For example, if content cannot be obtained without charging, the display device 105 accesses the content server 104 using the account information and purchase history included in the request signal, and obtains the corresponding content.

The display device 105 is connected to the wireless terminal 101 via wireless communication 102 when the wireless terminal 101 exists in the vicinity of the location where the display device 105 is installed (for example, within a range of 10 meters from the display device 105). be done. For example, when a user who has been out of the house returns home and the wireless terminal 101 owned by the user who has returned home comes to be within a predetermined range of the display device 105 , the wireless terminal 101 and the display device are connected via the wireless communication 102 . 105 are connected.

The display device 105 acquires the wireless terminal ID of the connected wireless terminal 101 from the wireless terminal 101 . Then, the display device 105 refers to a display mode registered in advance corresponding to the wireless terminal ID acquired from the wireless terminal 101, and displays a display screen based on the referred display mode.

<Display device configuration>
FIG. 2 is a diagram showing an overview of a configuration example of the display device 105 of the display system according to the first embodiment.

The communication unit 201 receives a request signal transmitted from the wireless terminal 101 and executes processing according to the received request signal. When receiving a request signal instructing acquisition of content, the communication unit 201 accesses the content server 104 via wireless communication and acquires the content. Further, when receiving a request signal for instructing viewing of content, the communication unit 201 acquires content from the content server 104 via wireless communication, and reproduces the acquired content. Note that, when receiving a request signal for instructing viewing of content, the communication unit 201 may reproduce the content stored therein.

Authentication section 202 authenticates wireless terminal 101 based on the SSID and password transmitted from wireless terminal 101 . Authentication section 202 inputs the wireless terminal ID and display mode of authenticated wireless terminal 101 to registration section 204 .

Registration unit 204 registers terminal information (wireless terminal ID and display mode) of wireless terminal 101 authenticated by authentication unit 202 . As a result, the terminal information of the parent terminal that can be used as a remote controller is registered. Also, the wireless terminal 101 registered as the remote controller for the display device 105 can be automatically registered as the parent terminal for the display device 105 . Note that the number of terminals that can be registered as parent terminals is not limited to one, and may be plural.

The identification unit 203 identifies whether or not a parent terminal having authority to acquire the first content from the content server 104 connected via the network is connected. More specifically, the identification unit 203 determines whether or not the wireless terminal ID of the currently connected wireless terminal 101 is registered by the registration unit 204 as a parent terminal (display mode is full access mode). Thereby, the identifying unit 203 identifies the wireless terminal 101 registered as the parent terminal. That is, the identification unit 203 recognizes the wireless terminal 101 whose display mode is the full access mode as the parent terminal. The identification unit 203 inputs to the display control unit 205 the wireless terminal ID identified as being registered as the parent terminal.

When a plurality of wireless terminals 101 are registered as parent terminals, the authentication unit 202 determines the order of priority of the registered wireless terminals 101 . For example, the authentication unit 202 inputs the wireless terminal ID of the first wireless terminal 101 registered among the plurality of wireless terminals 101 registered as parent terminals to the registration unit 204 as the wireless terminal ID of the parent terminal.

The wireless terminal 101 includes a parent terminal and a second wireless terminal that does not have the authority to acquire content from the content server 104 . Then, the identification unit 203 identifies whether the parent terminal is not connected and the child terminal, which is the second wireless terminal, is connected. Further, the identification unit 203 identifies the wireless terminal 101 that has transmitted the operation instruction to the display device 105 .

A display control unit 205 sets a display mode according to the identification result of the identification unit 203 . More specifically, when the identification unit 203 identifies that the parent terminal is not connected and the child terminal is connected, the display control unit 205 sets the viewing mode as the display mode. On the other hand, when the identification unit 203 recognizes that the parent terminal is connected, the display control unit 205 sets the full access mode as the display mode.

Further, when the identification unit 203 identifies that the parent terminal and the child terminal are connected, the display control unit 205 sets the full access mode as the display mode. Then, the display control unit 205 causes the display unit 206 to display a display screen based on the full access mode (described later in FIGS. 3A and 3C).

Note that the display control unit 205 may display the thumbnail screen based on the full access mode on a part of the display unit 206 of the display screen. Further, when the display device 105 receives a request signal for requesting switching of the display screen transmitted from the wireless terminal 101, the display control unit 205 changes the display screen based on the full access mode (described later in FIG. 3A). , (c)) may be displayed on the display unit 206 .

Further, the display control unit 205 sets the viewing mode as the display mode when the wireless terminal 101 that has transmitted the operation instruction is identified as the child terminal. Then, the display control unit 205 causes the display unit 206 to display a display screen (described later in FIG. 3B) based on the viewing mode.

Note that the display control unit 205 may display the thumbnail screen based on the viewing mode on a part of the display unit 206 of the display screen. Further, when the display device 105 receives a request signal requesting switching of the display screen transmitted from the wireless terminal 101, the display control unit 205 changes the display screen (described later in FIG. 3B) based on the viewing mode. You may make it display on the display part 206. FIG.

As described above, the display control unit 205 switches the display mode (full access mode, viewing mode) according to the display mode of the connected wireless terminal ID. As a result, the wireless terminal 101 other than the parent terminal can be prohibited from acquiring new content or entering into a new service contract.
