Description

  Embodiments described herein relate generally to a receiver, a communication method, and a server device.

  In recent years, with the spread of smartphones and tablet terminals, the number of users who simultaneously use smartphones and tablet terminals while watching broadcast programs is increasing. Along with this, attempts have been made to display information linked to the program that the user is currently viewing on these smartphones and tablet terminals.

JP 2013-66159 A

  As a display destination of information linked to a program, use of a Web browser is being studied, but a general Web browser is not an application premised on being linked to a program. For this reason, since a general Web browser does not actively acquire information associated with a program, it is necessary for a user to directly input a URL in order to link with a program.

  The present invention has been made in view of the above, and an object of the present invention is to provide a receiver, a communication method, and a server device that facilitate cooperation with a program using a general Web browser.

  In the present embodiment, the receiver displays the cooperative HTML application, and the terminal displays the terminal-side HTML application. When information related to the terminal-side HTML application is included in the cooperative HTML application related to the cooperation with the terminal based on broadcasting, the receiver and the terminal can be connected, and the URL of the terminal-side HTML application is set to the receiver. To the terminal.

FIG. 3 is a flowchart illustrating a procedure of a broadcast receiver detection process in the tablet terminal according to the embodiment. FIG. 4 is a flowchart illustrating a procedure of display processing of program-linked content in the terminal-side HTML browser unit of the tablet terminal according to the embodiment. FIG. 5 is a diagram illustrating an example of screen transition until an HTML application for program cooperation is displayed on the tablet terminal according to the embodiment. FIG. 6 is a flowchart illustrating an overall processing procedure in the broadcast receiver according to the embodiment.

  FIG. 1 is a diagram illustrating an example of a network environment according to the embodiment. In the network environment shown in FIG. 1, a smartphone 100, a tablet terminal 101, a broadcast receiver 102, and a router 103 are arranged in a home (home) network 120.

  Further, in the network environment shown in FIG. 1, a program cooperation content server 161 and an activation content server 171 are connected to an external network of the home network 120 via a public communication line 150.

  The broadcast station 180 provides programs and the like using broadcast waves. In addition to the program, the broadcast wave broadcast by the broadcast station 180 includes the URL of the acquisition destination of the content linked to the program. In the present embodiment, the information included in the broadcast wave is not limited to the URL of the acquisition destination of the content linked to the program, but may be the content linked to the program. As described above, the information included in the broadcast wave may be information that realizes cooperation with the program.

  The program cooperation content server 161 is a server provided by the broadcasting station 180 that provides a program, and is connected to the content storage device 162. The content storage device 162 stores content (HTML application) associated with the program.

  The startup content server 171 is a server provided by a provider of a portable terminal or the like in order to realize cooperation with a program, and includes a startup content storage device 172. The start-up content storage device 172 stores start-up content (start-up HTML application) used to link programs with a general Web browser.

  The broadcast receiver 102 is mounted with an antenna (not shown), and displays and stores a program included in a broadcast wave received via the antenna.

  In addition, the broadcast receiver 102 transmits and receives data to and from the program cooperation content server 161 and the like via the public communication line 150. Thereby, the broadcast receiver 102 can access the content (HTML application) linked to the program based on the URL extracted from the broadcast wave.

  In the present embodiment, an example in which an HTML application is applied as content linked to a program (program linked content) will be described. However, the present embodiment is not limited to the HTML application, and can be displayed with content or software linked to the program. I just need it.

  In the present embodiment, there are two types of program linkage content (HTML application). One type is program cooperation content to be displayed on the broadcast receiver 102 side, and the other type is program cooperation content to be displayed on the mobile terminal side such as the smartphone 100 or the tablet terminal 101.

  The broadcast receiver 102 accesses the program cooperation content from the URL extracted from the broadcast wave. The broadcast receiver 102 can transmit and receive information with the smartphone 100 and the tablet terminal 101 via the router 103.

  The smartphone 100 and the tablet terminal 101 can be connected to the broadcast receiver 102 via the router 103 wirelessly or by wire. In addition, the smartphone 100 and the tablet terminal 101 may have a mobile communication function such as 3G (third generation) communication.

  In the smartphone 100 and the tablet terminal 101, a cooperative application described later cooperates with the broadcast receiver 102 to access the program cooperative content.

  FIG. 2 is a block diagram illustrating the configuration of the broadcast receiver 102 and the tablet terminal 101 according to the present embodiment. In the present embodiment, the configuration of the smartphone 100 is the same as that of the tablet terminal 101, and a description thereof is omitted.

  The broadcast receiver 102 of FIG. 2 includes a receiver-side communication unit 201, a broadcast information acquisition unit 202, a receiver-side HTML browser unit 203, an information notification unit 204, and server software 205.

  The receiver-side communication unit 201 is an interface for communicating with other devices (for example, the smartphone 100 and the tablet terminal 101).

  The broadcast information acquisition unit 202 acquires information about the content to be displayed from the received broadcast wave. The broadcast information acquisition unit 202 of the present embodiment acquires the URL of an HTML application that cooperates with a program provided from a broadcast wave, as information about the content to be displayed, from the received broadcast wave. In addition, the present embodiment is not limited to acquiring a URL from a broadcast wave, and an HTML application linked to a program may be acquired from the broadcast wave.

  The receiver-side HTML browser unit 203 displays various contents such as an HTML application. For example, the receiver-side HTML browser unit 203 displays content (HTML application) linked to the program being broadcast based on the information (URL) acquired by the broadcast information acquisition unit 202. Further, the receiver-side HTML browser unit 203 may display the content superimposed on the program being broadcast.

  This embodiment does not limit the method of acquiring the URL of the program cooperation content displayed on the mobile terminal. For example, it may be extracted from a broadcast wave or acquired from an HTML application displayed on the receiver-side HTML browser unit 203. For example, when extracting from a broadcast wave, the broadcast receiver 102 superimposes the URL of the program cooperation content displayed on the receiver side and the URL of the program cooperation content displayed on the mobile terminal, and each URL is received by the receiver ( The broadcast wave on which the identifier indicating the content to be displayed on which device of the broadcast receiver 102) and the portable terminal (smart phone 100 or tablet terminal 101) is superimposed is received. Then, the broadcast receiver 102 performs display of program-linked content and URL transmission to the tablet terminal 101 based on the identifier. In addition, the case where it acquires from an HTML application is mentioned later.

  The information notification unit 204 stores, in the address holding unit 206, the URL of the program cooperation content for mobile terminals such as the smartphone 100 and the tablet terminal 101 acquired by broadcast waves or communication. When the information notification unit 204 receives a request from a mobile terminal (for example, the smartphone 100 or the tablet terminal 101), the information notification unit 204 sends the URL stored in the address holding unit 206 according to the request to the mobile terminal (for example, the smartphone). 100 or tablet terminal 101).

  For example, when broadcasting of a program that is supposed to be linked with a mobile terminal (for example, the smartphone 100 or the tablet terminal 101) is started from the broadcast station 180, the broadcast receiver 102 first receives the broadcast wave. Then, the broadcast receiver 102 extracts the URL of the content (HTML application) linked to the program for the device from the received broadcast wave, accesses the URL, and the receiver-side HTML browser unit 203 The content (HTML application) linked to the program for the apparatus is acquired, interpreted, and displayed.

  The content (HTML application) that the receiver-side HTML browser unit 203 cooperates with the displayed program for its own device includes a URL for cooperation with the mobile terminal (for example, the smartphone 100 or the tablet terminal 101). When the information is present, the information notification unit 204 causes the address holding unit 206 to hold a URL for cooperation with the mobile terminal (for example, the smartphone 100 or the tablet terminal 101). When the broadcast receiver 102 acquires the linked content (HTML application) for the mobile terminal from the broadcast wave, the broadcast receiver 102 assigns and stores a URL to the linked content, puts it under the control of its own server software 205, The URL provided by itself may be held in the address holding unit 206.

  And when a cooperation request | requirement is received from a portable terminal (for example, the smart phone 100 or the tablet terminal 101), the information notification part 204 is set to the address holding | maintenance part 206 with respect to a portable terminal (for example, the smart phone 100 or the tablet terminal 101). The stored URL is transmitted.

  In the present embodiment, the server software 205 of the broadcast receiver 102 and a mobile terminal (for example, the smartphone 100 or the tablet terminal) are used in order to reduce the effort of establishing a connection each time information is transmitted and received when performing program cooperation. 101)) the terminal-side HTML browser unit 213 maintains a connection for bidirectional communication.

  The server software 205 is used for transmission / reception between the terminal-side HTML browser unit 213 of the mobile terminal of the mobile terminal (for example, the smartphone 100 or the tablet terminal 101), the receiver-side HTML browser unit 203 of the broadcast receiver 102, and the like. Provide services. In response to the connection request, the server software 205 establishes a connection between the receiver-side HTML browser unit 203 and the terminal-side HTML browser unit 213 of the mobile terminal, thereby realizing data transmission / reception.

  By the way, when performing the program cooperation by performing mutual communication between the receiver-side HTML browser unit 203 or the information notification unit 204 and the terminal-side HTML browser unit 213 of the mobile terminal, depending on the contents of the service, high speed / high response is possible. A communication path is required.

  Furthermore, it is difficult for a general HTML browser to perform direct communication such as TCP and UDP, and there is a problem in responsiveness in HTTP polling when performing mutual communication.

  Therefore, in this embodiment, the server software 205 establishes a connection using WebSocket in order to realize high speed / high response. In this embodiment, the server software 205 functions as a WebSocket server, and the receiver-side Web browser unit 203 and the terminal-side HTML browser unit 213 of the mobile terminal (for example, the smartphone 100 or the tablet terminal 101) function as a WebSocket client.

  Further, the present embodiment is not limited to the method using WebSocket, and when high speed / high response is not required, an HTTP server is used as the server software 205, and the receiver-side Web browser unit 203 of the broadcast receiver 102 is used. Or the terminal side HTML browser part 213 of a portable terminal (for example, the smart phone 100 or the tablet terminal 101) may communicate by HTTP polling.

  By maintaining the connection, bidirectional communication of data is realized in real time between the information notification unit 204 or the receiver-side HTML browser unit 203 of the broadcast receiver 102 and the terminal-side HTML browser unit 213 of the mobile terminal. . Thereby, the program cooperation content currently displayed on the terminal side HTML browser part 213 of a portable terminal can be controlled from the broadcast receiver 102 in real time.

  The tablet terminal 101 includes a terminal-side communication unit 211, a cooperative application 212, and a terminal-side HTML browser unit 213.

  The terminal-side communication unit 211 is an interface for communicating with other devices (for example, the broadcast receiver 102).

  The terminal-side HTML browser unit 213 displays various contents such as an HTML application.

  The terminal-side HTML browser unit 213 may be a commonly used Web browser or the like. When such a general Web browser displays information, it is necessary to communicate with the provider of the information. However, a general Web browser is not provided with a function for spontaneous communication. In other words, a general Web browser is rarely provided with a function for automatically detecting and connecting to a service provided from the broadcast receiver 102 side. For this reason, conventionally, it has been necessary for a user of a portable terminal to input an IP address or URL that he / she has examined through an interface.

  On the other hand, in this embodiment, the cooperation application 212 provided in the tablet terminal 101 transmits / receives information necessary for connection and availability of service for program cooperation with the broadcast receiver 102. After the execution, when the necessary information is available, the information is transferred to the terminal-side HTML browser unit 213 together with the activation request. Accordingly, it is possible for the terminal-side HTML browser unit 213 to realize program cooperation with the broadcast receiver 102 without collecting information necessary for connection, in other words, without special installation.

  The cooperative application 212 includes a detection unit 221, a reception unit 222, an interface display control unit 223, a receiver setting acquisition unit 224, an activation address holding unit 225, and a browser control unit 226. The cooperation application 212 collects information necessary for startup in order to display the program cooperation content for terminal cooperation, and performs a process of transferring the information to the terminal-side HTML browser unit 213. The cooperation application 212 does not need to be a dedicated application, and may be implemented with, for example, a remote control application for operating the broadcast receiver 102.

  The detection unit 221 detects a device (for example, the broadcast receiver 102) that can acquire information (for example, URL) related to program-linked content linked to a program provided by broadcast waves.

  In the present embodiment, when the user executes the cooperation application 212 to display the program cooperation content on the tablet terminal 101, the detection unit 221 detects a device in the home network 120.

  The receiving unit 222 receives identification information (for example, an IP address) necessary for connecting to the broadcast receiver 102 from the broadcast receiver 102.

  The receiver setting acquisition unit 224 transmits / receives data to / from the broadcast receiver 102 indicated by the received identification information via the terminal-side communication unit 211, and acquires information such as service support status of the broadcast receiver 102. . As the service support status, for example, information such as whether or not a URL of a program cooperation content for a mobile terminal can be provided, and a protocol used for establishing a connection are used. Then, the cooperation application 212 holds identification information (for example, an IP address) related to a device (for example, the broadcast receiver 102) identified as being capable of program cooperation.

  The interface display control unit 223 is a graphic user interface used for displaying the program cooperation application. Further, the interface display control unit 223 may prepare an interface serving as a remote controller for operating the broadcast receiver 102.

  The activation address holding unit 225 stores the URL of the activation content server 171 that provides the activation HTML application 261 in advance.

  The startup HTML application 261 is an HTML application that the terminal-side HTML browser unit 213 displays at startup in order to perform program cooperation. The startup HTML application includes a Websocket connection script (Websocket connection interface) 271 necessary for establishing a connection with the broadcast receiver 102 by WebSocket, and a library necessary for executing the program cooperation HTML application 251. A certain application connection API 272 is included.

  The browser control unit 226 is a startup HTML application 261 in which an interface (WebSocket connection script 271) for establishing a bidirectional communication connection (WebSocket in the present embodiment) is implemented with respect to the terminal-side HTML browser unit 213. The URL indicating the acquisition destination of the URL is delivered. Further, the browser control unit 226 delivers identification information (for example, an IP address) of the broadcast receiver 102 capable of transmitting a program-linked HTML application for mobile terminals to the terminal-side HTML browser unit 213.

  As a result, the terminal-side HTML browser unit 213 uses the interface (Websocket connection script 271) after reading the start-up HTML application 261 in which an interface for establishing a connection with WebSocket is installed. A connection by WebSocket can be established between the information notification unit 204 of the broadcast receiver 102 and the HTML browser unit 203 on the receiver side via the 205.

  Then, the terminal-side HTML browser unit 213 receives the URL of the program cooperation HTML application 251 from the information notification unit 204 of the broadcast receiver 102. This URL indicates the program cooperation content server 161 that provides the program cooperation HTML application 251. And the terminal side HTML browser part 213 displays the program cooperation content (HTML application) for portable terminals by accessing received URL. Thereby, the display of the program cooperation content (HTML application) for portable terminals is realizable in the terminal side HTML browser part 213. FIG.

  Next, the detection process of the broadcast receiver 102 in the cooperation application 212 of the tablet terminal 101 according to the present embodiment will be described. FIG. 3 is a flowchart showing a procedure of the above-described processing in the tablet terminal 101 according to the present embodiment. Note that the smartphone 100 performs the same processing, and a description thereof is omitted.

  First, the detection unit 221 of the cooperative application 212 detects a device that can be connected to the home network 120 to which the tablet terminal 101 is connected (step S301). As a device detection method, UPnP SSDP may be used.

  When the detection unit 221 detects a device, the detection unit 221 determines whether there is an unconfirmed device (step S302). When the detection unit 221 determines that there is an unconfirmed device (step S302: Yes), the receiver setting acquisition unit 224 communicates with the detected unconfirmed device and is a device that supports the terminal cooperation service. A confirmation request is made (step S303). Then, the receiver setting acquisition unit 224 determines whether or not the unconfirmed device is compatible with the terminal cooperation service based on the setting acquired from the unconfirmed device (step S304). If it is determined that the terminal cooperation service is not supported (step S304: No), the processing is performed again from step S301.

  On the other hand, when the receiver setting acquisition unit 224 determines that the terminal cooperation service is supported (step S304: Yes), in addition to the address information, it is necessary for connection from the device (for example, the broadcast receiver 102). Protocol information and the like are acquired, and the acquired address information (IP address) and the like of the device is held in an SSD (not shown) or the like (step S305). Thereafter, the processing is performed again from step S301.

  In step S302, when it is determined that there is no unconfirmed device among the devices detected by the detection unit 221, in other words, all the devices have been confirmed (step S302: No), the process ends. The process shown in FIG. 3 may be performed every time the cooperative application 212 is executed. Moreover, you may update regularly or by a user's operation.

  With the processing shown in FIG. 3, the IP address of the broadcast receiver 102 can be held. Thereafter, the user performs an operation for displaying the program cooperation content from the screen displayed by the interface display control unit 223 of the tablet terminal 101.

  Next, the display process of the program cooperation content in the terminal side HTML browser part 213 of the tablet terminal 101 concerning this embodiment is demonstrated. FIG. 4 is a flowchart showing the above-described processing procedure in the terminal-side HTML browser unit 213 of the tablet terminal 101 according to the present embodiment. Note that the smartphone 100 performs the same processing, and a description thereof is omitted.

  It is assumed that the interface display control unit 223 of the tablet terminal 101 is displaying an operation screen before performing the program linked content display process. When an activation button or the like is pressed on the operation screen, the URL of the activation HTML application is transferred to the terminal-side HTML browser unit 213, and the process is started.

  First, the terminal-side HTML browser unit 213 receives the URL of the startup content server 171 that provides the startup HTML application 261 from the cooperative application 212 (step S401). This URL is stored in the activation address holding unit 225, and is the URL of the HTML application that is read first when the terminal-side HTML browser unit 213 is activated, regardless of the acquisition destination of the program-linked content.

  Then, the terminal-side HTML browser unit 213 reads the activation HTML application 261 from the received URL (step S402). As a result, the terminal-side HTML browser unit 213 acquires an interface for connecting to the broadcast receiver 102 via WebSocket and a library for executing the program cooperation HTML application.

  Further, the terminal-side HTML browser unit 213 acquires information such as the IP address of the broadcast receiver 102 of the connection destination from the cooperation application 212 (step S403).

  The terminal-side HTML browser unit 213 makes a connection request to the server software 205 of the broadcast receiver 102 indicated by the acquired IP address using the WebSocket interface included in the startup HTML application 261 ( Step S404). Then, the terminal-side HTML browser unit 213 determines whether or not the server software 205 of the broadcast receiver 102 can be connected with WebSocket (step S405). If the connection could not be established (step S405: No), the process is terminated.

  On the other hand, if the terminal-side HTML browser unit 213 can be connected to the server software 205 of the broadcast receiver 102 using WebSocket (step S405: Yes), the terminal-side HTML browser unit 213 uses the script described in the startup HTML application 261. Accordingly, the broadcast receiver 102 is inquired whether the URL of the content (HTML application) for the portable terminal is set in the information notification unit 204. Then, from the information notification unit 204 of the broadcast receiver 102, information necessary for displaying the content linked to the program, such as the URL of the program linked HTML application 251 for the portable terminal, is received as a result of the inquiry (step) S406). The URL is the URL of the program cooperation HTML application 251 stored in the program cooperation content server 161. If the broadcast receiver 102 acquires and stores the program cooperation HTML application 251 for the portable terminal, the URL A URL indicating a storage location may be used. Then, the terminal-side HTML browser unit 213 sets the received URL in the terminal-side HTML browser unit 213 in accordance with the script described in the startup HTML application 261.

  In this embodiment, an example in which a URL is inquired to the terminal-side HTML browser unit 213 is described. However, when the broadcast receiver 102 side establishes a connection with a mobile terminal (for example, the tablet terminal 101), a response or the like is used. An already set URL may be transmitted.

  Then, the terminal-side HTML browser unit 213 determines whether there is an HTML application in the received URL (step S407). If it is determined that there is no HTML application in the received URL (step S407: No), the process ends while maintaining the display of the startup HTML application. Alternatively, the terminal-side HTML browser unit 213 may be terminated and the screen of the cooperative application 212 may be returned.

  On the other hand, when the terminal-side HTML browser unit 213 determines that there is an HTML application in the received URL (step S407: Yes), the terminal-side HTML browser unit 213 receives the program cooperation HTML application 251 for the portable terminal from the received URL (step S408). .

  Thereafter, the terminal-side HTML browser unit 213 displays the received program cooperation HTML application 251 (step S409). At that time, the terminal-side HTML browser unit 213 may change the location setting of the browser in order to display the program cooperation HTML application 251. Further, in order to display the program cooperation HTML application 251, the application connection API 272 included in the startup HTML application 261 may be used. The application connection API may be created using, for example, Java (registered trademark) Script (registered trademark).

  When displaying an HTML application for terminal cooperation, as in the case of displaying the startup HTML application 261, information necessary for communication with the broadcast receiver 102 is given as a query, and a connection by WebSocket is established. Be able to maintain. As a result, when the URL of the new HTML application for terminal cooperation is set again, the terminal-side HTML browser unit 213 acquires a new URL via the connection by WebSocket, and the HTML application indicated by the URL is acquired. indicate.

  Thereafter, the terminal-side HTML browser unit 213 communicates with the broadcast receiver 102 connected via WebSocket, and controls the program cooperation HTML application 251 so as to cooperate with the program according to information transmitted from the broadcast receiver 102. Is performed (step S410).

  Next, the screen transition until the program cooperation HTML application is displayed on the tablet terminal 101 will be described. FIG. 5 is a diagram illustrating an example of screen transition until the HTML application for program cooperation is displayed on the tablet terminal 101. Note that the description of the smartphone 100 is omitted assuming that the same screen transition is performed.

  First, as illustrated in FIG. 5A, when the cooperation application 212 of the tablet terminal 101 is executed, the interface display control unit 223 of the cooperation application 212 also has a graphic having a remote controller function of the broadcast receiver 102. -A user interface screen 501 is displayed. On the screen 501 shown in (A), an activation button 502 for performing program cooperation and a setting button 503 for selecting a connection destination broadcast receiver are displayed. The cooperation application 212 performs the above-described device detection and the like together with the screen display shown in FIG. Note that the cooperation application 212 may change the display mode of the activation button 502 in accordance with the availability of the cooperation function. That is, in S406 of FIG. 4, when it is not possible to confirm that the URL of the content for the mobile terminal (HTML application) is set in the information notification unit 204 of the broadcast receiver 102, the cooperative application 212 displays the start button 502. A display form such as gray out may be used, and if it can be confirmed, it may be highlighted or blinked.

  FIG. 5B shows an example of a screen for selecting a connection destination broadcast receiver displayed by the interface display control unit 223 when the pressing of the setting button 503 in FIG. 5A is accepted. In (B), the interface display control unit 223 displays a list 511 of detected devices. Then, when the user selects a connection destination broadcast receiver from the detected device list 511 and presses the OK button 512, the selected broadcast receiver becomes a connection destination when the program is linked, and FIG. The screen shown by (A) is displayed again.

  Next, when a user views a broadcast program, knows the existence of program-linked content for a portable terminal, and wants to execute the content, the start button shown on the screen 501 in (A) Press 502. In addition, although this embodiment demonstrates the example which used button operation as operation for performing a screen transition, it does not restrict | limit to button operation. For example, “display program-linked content” may be selected from the menu, or display control of the program-linked content may be started by some operation (for example, shaking the terminal). Furthermore, when a broadcast receiver to be connected is set in advance, the program-linked content activation process may be performed immediately after the cooperation application 212 is executed without pressing the activation button 502.

  A screen example 521 in FIG. 5C shows a screen example of the startup HTML application 261 displayed by the terminal-side HTML browser unit 213 when the pressing of the startup button 502 in FIG. 5A is accepted. The screen example shown in (C) is a screen example of an HTML application read from the URL held in the activation address holding unit 225. While the screen indicated by (C) is displayed, the terminal-side HTML browser unit 213 establishes a connection with the server software 205 of the broadcast receiver 102. Then, when the terminal-side HTML browser unit 213 acquires the URL of the portable terminal program cooperation HTML application 251 from the broadcast receiver 102, the screen transitions to the screen shown in (D).

  A screen example 523 in FIG. 5D illustrates a screen example of the program cooperation HTML application 251 displayed by the terminal-side HTML browser unit 213. In the program cooperation HTML application 251 displayed by the terminal-side HTML browser unit 213, information is transmitted and received via the broadcast receiver 102 and WebSocket, thereby realizing real-time cooperation with the program.

  Next, overall processing of the broadcast receiver 102 according to the present embodiment will be described. FIG. 6 is a flowchart showing a procedure of the above-described processing in the broadcast receiver 102 according to the present embodiment.

  First, the broadcast information acquisition unit 202 receives a broadcast wave (step S601). Thereafter, the receiver-side HTML browser unit 203 displays an HTML application based on the received broadcast wave (step S602). The HTML application may be displayed superimposed on a broadcast wave program.

  Then, the information notification unit 204 acquires the URL of the program cooperation HTML application 251 to be displayed on the mobile terminal side from the displayed HTML application, and stores the URL in the address holding unit 206 (step S603).

  Thereafter, the server software 205 receives a connection request from the mobile terminal (step S604). As a result, the server software 205 performs a connection using the WebSocket with the mobile terminal (step S605).

  In response to a request from the mobile terminal, the information notification unit 204 transmits the URL of the program cooperation HTML application 251 stored in the address holding unit 206 (step S606).

  Thereafter, the information notification unit 204 requests control of the program cooperation HTML application to the portable terminal with which connection has been established according to the information included in the broadcast wave received by the broadcast information acquisition unit 202 (step S607). ).

  In this embodiment, an example in which a connection destination is specified by a URL or an IP address has been described. However, information specifying a device is not limited to a URL or an IP address, and other information such as a domain name is used. Also good.

  In the mobile terminal (for example, the smartphone 100 or the tablet terminal 101) of the present embodiment, the cooperative application 212 is provided, the cooperative application 212 holds the URL of the startup HTML application 261, and the broadcast receiver 102 is detected. Thus, even when a general Web browser is used for the terminal-side HTML browser unit 213, the program-linking HTML application 251 is input to the terminal-side HTML browser unit 213 without performing an operation such as directly inputting a URL. Can be displayed. Thereby, even when a general Web browser is used, cooperation with a program can be easily realized.

  In this embodiment, since a general Web browser can be applied, terminal cooperation can be realized at a low cost while maintaining the simplicity of connection. In addition, it is possible to easily use a WebSocket client or the like pre-installed in the Web browser as a means for high-speed / high-response communication. As a result, it has become possible to provide high performance services through mutual communication.
