[Figure 3] FIG. 10 is a diagram illustrating an example of a connection screen. [Figure 4] FIG. 2 is a diagram illustrating a functional configuration of a communication terminal.

[Figure 6] FIG. 10 is a sequence diagram illustrating an example of a processing flow in the information processing system. DETAILED DESCRIPTION OF THE INVENTION

[0024] [Outline of Information Processing System S] 1 is a diagram showing an overview of an information processing system S. The information processing system S has a set-top box (hereinafter referred to as "STB") 1 as a display control device, a display device 2, a communication terminal 3, and a server 4, and is a system that enables a user to operate the STB 1 when a malfunction or the like occurs in the STB 1.

[0025] The STB 1 is connected to the display device 2 via an HDMI (High-Definition Multimedia Interface) (registered trademark) or the like. While the STB 1 can perform short-range wireless communication with external devices such as a communication terminal 3 via Bluetooth (registered trademark) or the like, it does not have an interface for connecting to a communication network such as the Internet, and is therefore unable to connect to such a communication network. When the STB 1 detects that a malfunction or the like has occurred in itself, it displays on the display device 2 a code including connection information for the communication terminal 3 to connect to the STB 1 via wireless communication and error information indicating the malfunction or the like ((1) in FIG. 1). The code is, for example, a two-dimensional code such as a QR code (registered trademark).

[0026] The communication terminal 3 is, for example, a smartphone with an imaging function. The communication terminal 3 reads the code displayed on the display device 2 ((2) in FIG. 1) and acquires the connection information and error information contained in the code ((3) in FIG. 1). Upon acquiring the error information, the communication terminal 3 transmits the acquired error information to the server 4 ((4) in FIG. 1).

[0027] The server 4 is, for example, a server operated by a support center that supports the STB 1, and provides operation information for the STB 1 to resolve the error indicated by the error information. When the server 4 acquires error information from the communication terminal 3, it identifies operation information for the STB 1 to resolve the error based on the error indicated by the acquired error information, and transmits the identified operation information to the communication terminal 3 ((5) in FIG. 1).

[0028] When the communication terminal 3 receives the operation information, it displays an operation screen for operating the STB 1 based on the operation information on its display unit, and in response to receiving an operation from the user, transmits the operation information to the STB 1 ((6) in FIG. 1). In this way, the information processing system S can provide a solution when a malfunction occurs in an electronic device that cannot be connected to a communication network.

[0029] [STB1 functional configuration] Next, the functions of the STB 1 and communication terminal 3 of the information processing system S will be described. First, the functional configuration of the STB 1 will be described. Here, a description of the general functions of the STB 1 as a set-top box will be omitted, and the functions of the STB 1 according to the present invention will be described. FIG. 2 is a diagram showing the functional configuration of the STB 1. The STB 1 has a short-range wireless communication unit 11, a storage unit 12, and a control unit 13.

[0030] The short-distance wireless communication unit 11 is an interface for short-distance wireless communication for transmitting and receiving data to and from the communication terminal 3 via Bluetooth, NFC (Near Field Communication), or the like.

[0031] The storage unit 12 is a storage medium that stores various types of data, and includes a ROM (Read Only Memory), a RAM (Random Access Memory), etc. The storage unit 12 stores programs executed by the control unit 13. The storage unit 12 stores programs that cause the control unit 13 to function as a detection unit 131, a display control unit 132, a connection unit 133, a receiving unit 134, and an operation control unit 135.

[0032] The control unit 13 is, for example, a CPU (Central Processing Unit). The control unit 13 executes a program stored in the storage unit 12, thereby functioning as a detection unit 131, a display control unit 132, a connection unit 133, a receiving unit 134, and an operation control unit 135.

[0033] The detection unit 131 detects errors that occur in the STB 1. For example, the detection unit 131 detects various errors such as a communication error that prevents the STB 1 from receiving a receivable broadcast signal, or a decoding error that prevents the STB 1 from generating an image based on a broadcast signal.

[0034] When the detection unit 131 detects an error, the display control unit 132 causes the display device 2 to display connection information for establishing a wireless communication connection with the communication terminal 3 of the user using the STB 1. For example, the display control unit 132 generates a code including the connection information and error information indicating the error detected by the detection unit 131, and causes the display device 2 to display a connection screen including the code, thereby displaying the connection information on the display device 2. Here, the connection information includes, for example, an STB ID such as a serial number for identifying the STB 1, and the communication terminal 3 can identify the STB 1 based on the STB ID.

[0035] Fig. 3 is a diagram showing an example of the connection screen. As shown in Fig. 3, the connection screen displays a two-dimensional code including connection information and error information, as well as a message prompting the user to read the code using the communication terminal 3.

[0036] Based on the connection information, the connection unit 133 connects to the communication terminal 3 via wireless communication. Specifically, the code is read in the communication terminal 3, the connection information contained in the code is acquired, and in response to a connection request being made based on the connection information, the connection unit 133 connects to the communication terminal 3 via short-range wireless communication by coordinating the short-range wireless communication unit 11 with a short-range wireless communication unit 32 of the communication terminal 3, which will be described later.

[0037] The receiving unit 134 receives, from the communication terminal 3 via short-range wireless communication, operation information for operating the STB 1 to resolve the error that the communication terminal 3 has acquired from the server 4. After the STB 1 and the communication terminal 3 are connected via short-range wireless communication by the connecting unit 133, the receiving unit 134 receives the operation information from the communication terminal 3 via short-range wireless communication.

[0038] The operation control unit 135 controls the operation of the STB 1 based on the operation information received by the receiving unit 134. For example, after the detecting unit 131 detects an error, the operation control unit 135 controls the operation of the STB 1 based on the operation information received by the receiving unit 134 for a predetermined operable time.

[0039] The start timing of the operable time is the timing when the STB 1 and the communication terminal 3 start wireless communication, that is, the timing when the connection unit 133 communicates with the communication terminal 3 to establish short-range wireless communication cooperation and establishes a connection. Note that the start timing of the operable time is set to the timing when the STB 1 and the communication terminal 3 start wireless communication, but is not limited to this, and may be the timing when the display control unit 132 causes the display device 2 to display a code including connection information.

[0040] Furthermore, the operation control unit 135 may specify a time for which the operation of the STB 1 is controlled based on the content of the operation indicated by the operation information received by the receiving unit 134, and extend the operable time based on the specified time. For example, the content of the operation indicated by the operation information and the time for which the operation of the STB 1 corresponding to the content is controlled are stored in association with each other in the storage unit 12. The operation control unit 135 then refers to the storage unit 12 and specifies a time for which the operation of the STB 1 is controlled, corresponding to the content of the operation indicated by the received operation information.

[0041] The operation control unit 135 calculates the difference between the remaining operable time at the time when the received operation information was identified and the time for controlling the identified operation of the STB 1, and extends the operable time to exceed the calculated difference. In this way, the STB 1 can adjust the operable time to an appropriate time corresponding to the operation information from the communication terminal 3.

[0042] [Functional configuration of communication terminal 3] Next, a description will be given of the functional configuration of the communication terminal 3. Fig. 4 is a diagram showing the functional configuration of the communication terminal 3. The communication terminal 3 has a communication unit 31, a short-range wireless communication unit 32, an imaging unit 33, a display unit 34, an operation unit 35, a storage unit 36, and a control unit 37.

[0043] The communication unit 31 is a communication interface for transmitting and receiving data to and from an external device such as the server 4 via a communication network such as the Internet or a mobile phone line. The short-distance wireless communication unit 32 is a short-distance wireless communication interface for transmitting and receiving data to and from the STB via Bluetooth, NFC, or the like.

[0044] The imaging unit 33 is, for example, a camera. The imaging unit 33 captures an image of the code displayed on the display device 2, thereby reading the code. The display unit 34 is a display that displays various types of information. The operation unit 35 is, for example, a button or a touch panel provided overlaid on the display unit 34, and receives operations from the user of the communication terminal 3.

[0045] The storage unit 36 ​​is a storage medium including a ROM, a RAM, etc. The storage unit 36 ​​stores a program executed by the control unit 37. The storage unit 36 ​​stores a program that causes the control unit 37 to function as an acquisition unit 371, a connection unit 372, a reception unit 373, and a transmission unit 374.

[0046] The control unit 37 is, for example, a CPU. The control unit 37 executes a program stored in the storage unit 12, thereby functioning as an acquisition unit 371, a connection unit 372, a reception unit 373, and a transmission unit 374.

[0047] The acquisition unit 371 acquires connection information for connecting to the STB 1 via wireless communication and error information indicating an error that has occurred in the STB 1. For example, in response to a user's imaging operation using the operation unit 35, the acquisition unit 371 reads a code including the connection information and error information displayed on the display device 2 using the imaging unit 33, and acquires the connection information and error information included in the read code.

[0048] When acquiring error information, acquiring unit 371 transmits the acquired error information to server 4 and acquires operation information of STB 1 corresponding to the error information from server 4. For example, memory unit 36 ​​stores the URL of server 4 as the access destination, and when acquiring error information, acquiring unit 371 adds the error information as a parameter to the URL of server 4 and transmits the error information to server 4 by accessing the URL. Then, acquiring unit 371 acquires operation information of STB 1 by acquiring an operation acceptance page including the operation information from server 4.

[0049] The acquisition unit 371 may transmit the acquired error information and the STBID included in the connection information to the server 4. Then, the acquisition unit 371 may acquire operation information identified based on the error information and the STBID from the server 4. In this way, the communication terminal 3 can acquire operation information of the STB 1 that corresponds to the model number of the STB 1 identified based on the STBID.

[0050] The acquisition unit 371 may also transmit the acquired error information and a captured image of the display device 2 captured by the imaging unit 33 to the server 4. Then, the acquisition unit 371 may acquire, from the server 4, operation information identified based on the error information and the model number of the display device 2 identified from the image of the display device 2 shown in the captured image. In this way, the communication terminal 3 can acquire operation information of the STB 1 that corresponds to the model number of the display device 2.

[0051] The acquisition unit 371 may also transmit error information and location information indicating the location of the communications terminal 3 to the server 4, and acquire from the server 4 operation information for resolving the error indicated by the error information, which is identified based on the error information and fault information in the area indicated by the location information. In this case, the acquisition unit 371 may acquire information indicating the cause of the error, which is identified based on the fault information and error information. Furthermore, if the acquisition unit 371 cannot resolve the fault information by controlling the STB 1 based on the fault information and error information, it may acquire only the information indicating the cause of the error. In this way, the communications terminal 3 can cause the user of the STB 1 to take appropriate action in response to an error corresponding to a fault that has occurred in a specific area.

[0052] Furthermore, the acquisition unit 371 may acquire, as operation information from the server 4, remote operation information that enables a support center that supports the STB 1 to remotely operate the STB 1. For example, if the error indicated by the error information is an error that is difficult to resolve by user operation, the acquisition unit 371 receives remote operation information that enables the support center to remotely operate the STB 1. Furthermore, the acquisition unit 371 may acquire, from the server 4, remote operation information that includes an extension request to extend the operable time of the STB 1.

[0053] Furthermore, the acquiring unit 371 transmits the error information to the server 4 and acquires the operation information corresponding to the error information from the server 4, but this is not limitative. The acquiring unit 371 may acquire the operation information by identifying operation information that resolves the error indicated by the error information, based on the acquired error information.

[0054] In this case, for example, the acquisition unit 371 may acquire in advance from the server 4 information for operation identification that associates error information with operation information corresponding to the error information, and store the information in the storage unit 36. Then, upon acquiring the error information, the acquisition unit 371 refers to the information for operation identification stored in the storage unit 36 ​​and acquires the operation information by identifying the operation information corresponding to the acquired error information. In this way, the communication terminal 3 can acquire the operation information even if it is unable to communicate with the server 4 due to a communication failure or the like at the time the error information is acquired.

[0055] The acquisition unit 371 transmitted the error information to the server 4, but if the two-dimensional code includes an STBID, the acquisition unit 371 may transmit the phone number assigned to the communication terminal 3 together with the STBID to the server 4. In this case, the server 4 receives the error information, the STBID, and the phone number assigned to the communication terminal 3 from the communication terminal 3.

[0056] The server 4 stores STB contract information that indicates a contract with a user regarding the use of the STB 1. The STB contract information includes an STB ID and a telephone number assigned to the communication terminal 3 owned by the user. When the server 4 receives error information and the STB ID from the communication terminal 3, it references the STB contract information that includes the STB ID and identifies the telephone number assigned to the communication terminal 3.

[0057] The server 4 transmits the operation information to the communication terminal 3 on the condition that the identified telephone number matches the telephone number of the communication terminal 3 that received the operation information. In this way, it is possible to prevent a communication terminal of a third party that is not a subscriber of the STB 1 from receiving the operation information illegally.

[0058] It should be noted that when the STB 1 is used by a family or the like, the subscriber of the STB 1 may be different from the user of the communication terminal 3, and the telephone number of the subscriber of the STB 1 may be different from the telephone number of the communication terminal 3. In response to this case, if the identified telephone number does not match the telephone number of the communication terminal 3 received by the server 4, the server 4 may refer to the contract information of the mobile phone, which includes the telephone number of the user managed by the communication carrier and the telephone numbers of other users associated with the user, and identify one or more other telephone numbers associated with the telephone number of the communication terminal 3 received by the server 4.

[0059] Then, the server 4 may transmit operation information to the communication terminal 3 on the condition that any one of the one or more other specified telephone numbers matches the telephone number specified from the STB contract information. In this case, the server 4 may transmit a message to the communication terminal to which the telephone number specified from the STB contract information is assigned, by SMS (Short Message Service) or the like, for accepting approval for operating the STB 1 based on the operation information, and may transmit operation information to the communication terminal 3 in response to accepting approval for the operation. In this way, if the user of the communication terminal 3 is a family member or the like of the subscriber of the STB 1, it is possible to transmit operation information to the communication terminal 3.

[0060] The connection unit 372 connects to the STB 1 via wireless communication based on the connection information acquired by the acquisition unit 371. For example, the connection unit 372 identifies the STB 1 to be connected based on the STB ID included in the connection information. Then, the connection unit 372 connects via short-range wireless communication by coordinating the short-range wireless communication unit 32 with the short-range wireless communication unit 11 of the identified STB 1.

[0061] The reception unit 373 displays an operation screen on the display unit 34 that accepts operation of the STB 1 using the operation information acquired by the acquisition unit 371, and accepts operation of the STB 1 from the user. For example, the reception unit 373 displays the operation acceptance page acquired by the acquisition unit 371 as an operation screen on the display unit 34, and accepts operation of the STB 1 from the user.

[0062] Fig. 5 is a diagram showing an example of an operation screen. In the example of the operation screen shown in Fig. 5(a), it can be seen that the fault content, the support content corresponding to the fault content, and a button B1 for accepting transmission of operation information corresponding to the support content, i.e., operation information corresponding to error information, are displayed. In addition, the example of the operation screen shown in Fig. 5(b) shows an example in which the operation information is remote operation information, and it can be seen that an execute button B2 for permitting remote operation of the STB1 by the support center is displayed.

[0063] When the execute button B2 for permitting remote operation is pressed and the user requests remote support, the support center may troubleshoot while contacting the user. In this case, the reception unit 373 displays at least one of video, image, audio, and text information on the operation screen to explain the STB1 confirmation details that the user is requested to check.

[0064] In response to this, the reception unit 373 may select which of video, image, audio, and text information to include on the operation screen based on the remaining communication capacity that the communication terminal 3 can use for communication at a predetermined communication speed within a predetermined period. For example, the reception unit 373 may include only text information on the operation screen when the remaining communication capacity is less than a predetermined threshold, and may include at least one of video, image, and audio on the operation screen when the remaining communication capacity is equal to or greater than the predetermined threshold. In this manner, the communication terminal 3 can prevent excessive consumption of communication capacity when the remaining communication capacity is low.

[0065] The transmitter 374 transmits, via wireless communication, to the display control device operation information for operating the STB 1 to resolve the error indicated by the error information, which has been identified based on the error information acquired by the acquirer 371. The transmitter 374 transmits, via short-range wireless communication unit 32, to the STB 1 the operation information for the STB 1 acquired by the acquirer 371.

[0066] For example, in response to the reception unit 373 receiving an instruction to operate the STB 1 via the operation screen, the transmission unit 374 transmits operation information to the STB 1. For example, when button B1 is pressed on the operation screen shown in FIG. 5(a) and the reception unit 373 receives an instruction to operate the STB 1, the transmission unit 374 transmits operation information corresponding to button B1 to the STB 1.

[0067] 5(b) is pressed on the operation screen for accepting permission to remotely operate the STB 1, and the acceptance unit 373 accepts the operation of the STB 1, the transmission unit 374 transmits remote operation information corresponding to the button B1 to the STB 1. Here, if the remote operation information includes an extension request to extend the available operation time, the transmission unit 374 transmits the remote operation information including the extension request to the STB 1.

[0068] Note that the transmitting unit 374 receives operation information including an extension request from the server 4 and requests the STB 1 to extend the operable time by transmitting the operation information including the extension request to the STB 1, but this is not limited to this. The transmitting unit 374 may specify a time for controlling the operation of the STB 1 based on the content of control indicated by the operation information, and calculate an extension time for the operable time based on the specified time and the remaining time of the operable time. Then, the transmitting unit 374 may transmit the operation information and also transmit an extension request to the STB 1 to extend the operable time by the calculated extension time for the operable time. In this way, the STB 1 does not need to calculate the operation extension time, thereby reducing the load on the STB 1.

[0069] Furthermore, when remote operation information is transmitted to the STB 1 and remote operation is performed from the support center, a specific operation that is not performed in normal operations may be performed. The execution authority for executing the specific operation may be set higher than the execution authority for executing normal operations. In response to this, the acquisition unit 371 may acquire, from the server 4, authority control information for accepting a specific operation corresponding to a predetermined execution authority that is higher than the execution authority for executing normal operations, when receiving remote operation information, etc.

[0070] Then, when the acquisition unit 371 acquires the authority control information from the server 4, the transmission unit 374 may transmit the authority control information to the STB 1. In this case, when the reception unit 134 receives the authority control information and then receives operation information related to a specific operation that requires a predetermined authority, the operation control unit 135 of the STB 1 executes the specific operation. In this case, the authority control information may be encrypted based on key information corresponding to the STB ID so that it can be decrypted in the STB 1 that has the STB ID. In this way, the STB 1 can accept operation information for a specific operation with stronger authority and execute the specific operation only when it has received the authority control information.

[0071] [Processing flow in information processing system S] Next, a description will be given of the flow of processing in the information processing system S. Fig. 6 is a sequence diagram showing an example of the flow of processing in the information processing system S. This sequence starts when the detection unit 131 of the STB 1 detects an error that has occurred in the STB 1.

[0072] First, in response to the detection of an error by the detection unit 131, the display control unit 132 generates a code including connection information for establishing a short-range wireless communication connection with the communication terminal 3 and error information indicating the error (S1). The display control unit 132 causes the display device 2 to display the generated code (S2).

[0073] The acquisition unit 371 of the communication terminal 3 reads the code displayed on the display device 2 in response to the user's imaging operation using the operation unit 35 (S3), and acquires the connection information and error information contained in the read code (S4).

[0074] The acquisition unit 371 transmits the acquired error information to the server 4 (S5). Then, the acquisition unit 371 acquires the operation information by acquiring an operation reception page including operation information of the STB 1 corresponding to the error information from the server 4 (S6).

[0075] The connection unit 372 identifies the STB1 to be connected based on the STBID included in the connection information acquired by the acquisition unit 371, and establishes a short-range wireless communication connection with the STB1 based on the identified STBID (S7). Note that in this sequence, the connection unit 372 establishes a short-range wireless communication connection with the STB1 after S6, but this is not limiting, and the connection may be established via short-range wireless communication before the processing of S5 and S6, or may be established in parallel with the processing of S5 and S6.

[0076] The accepting unit 373 displays the operation acceptance page acquired by the acquiring unit 371 as an operation screen on the display unit 34 (S8). If the accepting unit 373 determines that an operation of the STB 1 has been accepted from the user on the operation screen (YES in S9), it proceeds to S10, and if it determines that an operation of the STB 1 has not been accepted (NO in S9), it executes S9 again.

[0077] In S10, the transmission unit 374 transmits the operation information to the STB 1. The reception unit 134 of the STB 1 receives the operation information from the communication terminal 3. Next, the operation control unit 135 controls the operation of the STB 1 based on the operation information received by the receiving unit 134 (S11).

[0078] [Variations] In the above-described embodiment, the display control unit 132 generates a code including connection information and error information and causes the display device 2 to display the code, but this is not limiting. The display control unit 132 may generate a code including connection information but not error information and cause the display device 2 to display the code. In this case, the control unit 13 of the STB 1 may transmit an error code to the communication terminal 3 via short-range wireless communication in response to the connection unit 133 connecting to the communication terminal 3 via short-range wireless communication.

[0079] [Effects on Information Processing System S] As described above, in the information processing system S according to this embodiment, the communication terminal 3 acquires connection information for connecting to the STB 1 via wireless communication and error information indicating an error that has occurred in the STB 1, connects to the STB 1 via wireless communication based on the connection information, and transmits operation information to the STB 1 via wireless communication for operating the STB 1 to resolve the error identified based on the acquired error information. In this way, the information processing device 1 can provide a solution when a malfunction occurs in an electronic device that cannot connect to a communication network.

[0080] Furthermore, this invention will make it possible to contribute to Goal 9 of the United Nations' Sustainable Development Goals (SDGs), which is "Build resilient infrastructure, promote inclusive and sustainable industrialization, and promote innovation and resilience."
