Note that the initial settings refer to various settings (including network settings and tuner reception settings, which will be described later) that are performed when the playback device 4 is turned on for the first time after the playback device 4 is purchased.

[0016] [1-2. System Functional Configuration] The functional configuration of the system 2 according to the embodiment will be described with reference to Fig. 2. Fig. 2 is a block diagram showing the functional configuration of the system 2 according to the embodiment.

[0017] As shown in FIG. 2, the playback device 4 has, as its functional configuration, a tuner 16, a recording processing circuit 18, a playback processing circuit 20, a graphics module 22, a video signal processing circuit 24, a front panel display unit 10, a remote control receiver 26 (an example of a reception unit), a first communication module 28 (an example of a first communication unit), a second communication module 30 (an example of a second communication unit), a wired LAN I / F (Local Area Network Interface) 32, a USB I / F (Universal Serial Bus Interface) 34, a controller 36 (an example of a control unit), and an HDMI transmission unit 38 (an example of a detection unit).

[0018] An antenna 40 is disposed outside the playback device 4. The antenna 40 is connected to the tuner 16 and receives broadcast waves (digital broadcast signals) transmitted from a broadcast station. Note that the broadcast waves include radio waves for broadcasting, for example, terrestrial digital broadcasting, BS (Broadcasting Satellites) digital broadcasting, CS (Communication Satellites) digital broadcasting, and the like.

[0019] The tuner 16 receives a broadcast program (digital broadcast program) contained in a broadcast wave from an antenna 40.

[0020] The recording processing circuit 18 performs processing for recording the broadcast program received by the tuner 16 onto the recording medium 42. Note that the recording medium 42 is, for example, an optical disc such as a BD or DVD inserted into the playback device 4, or an HDD built into the playback device 4.

[0021] The playback processing circuit 20 performs processing for playing back video content such as broadcast programs recorded on a recording medium 42 .

[0022] The graphics module 22 generates various screens to be displayed on the display device 6 .

[0023] The video signal processing circuit 24 generates a video signal and an audio signal representing the video content reproduced by the reproduction processing circuit 20, and outputs the generated video signal and audio signal to the HDMI transmission unit 38. The video signal processing circuit 24 also generates a video signal representing various screens generated by the graphic module 22, and outputs the generated video signal to the HDMI transmission unit 38.

[0024] The front panel display unit 10 is a liquid crystal display for displaying various types of information.

[0025] The remote control light receiving unit 26 receives instructions input by a user through a remote control (not shown) of the playback device 4. The remote control light receiving unit 26 receives a remote control signal from the remote control, and outputs the received remote control signal to the controller 36.

[0026] The first communication module 28 is a communication module for communicating with the terminal device 8 by close-proximity wireless communication such as BLE (Blutooth (registered trademark) Low Energy).

[0027] The second communication module 30 is a communication module for wirelessly communicating with a wireless network 44 (one example of a network). The wireless network 44 is, for example, a wireless LAN conforming to the IEEE802.11 series, and is WiFi (registered trademark) in the 2.4 GHz or 5 GHz band. The wireless network 44 is constructed by a wireless access point (AP) 46 connected to an Internet line. It is assumed that the SSID (Service Set Identifier) ​​of the wireless access point 46 is, for example, "abcd012" and the passcode is "xxxyyyy". It is also assumed that the terminal device 8 has wireless communication established with the wireless access point 46 and is connected to the wireless network 44.

[0028] The wired LAN I / F 32 is a communication interface for mutually connecting the playback device 4 and the wireless access point 46. The wired LAN I / F 32 is connected to the wireless access point 46 via a wired network constructed of a wired LAN using, for example, an Ethernet (registered trademark) cable.

[0029] The USB I / F 34 is a communication interface for connecting the playback device 4 and a USB device (not shown) to each other.

[0030] The controller 36 controls the operation of the playback device 4 based on a remote control signal from the remote control receiver 26 and a control signal (described later) from the HDMI transmitter 38. Specifically, the controller 36 executes various processes for initial setting of the playback device 4, for example. The controller 36 also controls the display of various information on the front panel display unit 10. The controller 36 also instructs the graphic module 22 to generate various screens to be displayed on the display device 6. The controller 36 also controls the first communication module 28 and the second communication module 30. The controller 36 also transmits and receives various data via the wired LAN I / F 32 and the USB I / F 34.

[0031] The HDMI transmission unit 38 is connected to the HDMI reception unit 50 of the display device 6 via the cable 12 (see FIG. 1). The HDMI transmission unit 38 transmits video signals and audio signals to the HDMI reception unit 50 of the display device 6 through a Transition-Minimized Differential Signaling (TMDS) channel via the cable 12. In addition, the HDMI transmission unit 38 transmits and receives control signals (CEC commands) to and from the HDMI reception unit 50 of the display device 6 through a Consumer Electronics Control (CEC) channel via the cable 12.

[0032] The HDMI standard prescribes CEC for linking multiple HDMI devices. According to CEC, CEC commands are communicated bidirectionally between multiple HDMI devices. This communication is called CEC communication. By this CEC communication, the HDMI transmission unit 38 can detect, for example, the power state (power on state or power off state) of the display device 6 connected to the playback device 4.

[0033] As shown in FIG. 2, the display device 6 includes a display unit 14, a controller 48, and an HDMI receiving unit 50.

[0034] The display unit 14 is a liquid crystal display panel for displaying various screens and the like.

[0035] The controller 48 controls the operation of the display device 6 based on a control signal from the HDMI receiving unit 50. The controller 48 also controls the display of various screens and the like on the display unit 14.

[0036] The HDMI receiving unit 50 receives a video signal and an audio signal from the HDMI transmitting unit 38 of the playback device 4 by the TMDS channel via the cable 12. In addition, the HDMI receiving unit 50 transmits and receives a control signal to and from the HDMI transmitting unit 38 of the playback device 4 by the CEC channel via the cable 12.

[0037] [1-3. Flow of initial settings for playback device] A flow of initial setting of the playback device 4 according to the embodiment will be described with reference to Fig. 3 and Fig. 4. Fig. 3 is a flowchart showing the flow of initial setting of the playback device 4 according to the embodiment. Fig. 4 is a diagram showing an example of a screen displayed on the display device 6 according to the embodiment.

[0038] The following describes a case where a user, after purchasing the playback device 4, connects the playback device 4 and the display device 6 via the cable 12 and turns on the power of the playback device 4 for the first time.

[0039] 3, when a user turns on the power of the playback device 4 (S101), the playback device 4 outputs a grayed-out screen to the display device 6 (S102). This grayed-out screen is generated by the graphics module 22 and output to the display device 6 by the HDMI transmission unit 38.

[0040] The HDMI transmission unit 38 detects the power state of the display device 6 based on a control signal from the display device 6 (S103). When the power state of the display device 6 is the power off state (i.e., the HDMI transmission unit 38 does not detect that the display device 6 is in the power on state) ("power off state" in S103), the first communication module 28 transmits a beacon signal by BLE (S104). That is, advertising by BLE is started, and the first communication module 28 goes into a state of waiting for a connection request from the terminal device 8 (S105).

[0041] The beacon signal from the first communication module 28 is received by the terminal device 8 located near the playback device 4. Below, a case will be described in which the user performs an operation to transmit a connection request to the playback device 4 using the terminal device 8 that has received the beacon signal. As a result, the terminal device 8 that has received the beacon signal transmits a connection request to the playback device 4.

[0042] When the first communication module 28 receives a connection request from the terminal device 8 that has received the beacon signal (YES in S105), the first communication module 28 stops transmitting the beacon signal (S106) and starts close proximity wireless communication by BLE with the terminal device 8 that has received the beacon signal (S107). That is, close proximity wireless communication between the first communication module 28 and the terminal device 8 is established.

[0043] Thereafter, the controller 36 executes network settings (an example of first settings related to the playback device 4) between the terminal device 8 and the second communication module 30 for connecting the playback device 4 to the wireless network 44 (S108). As a result, the second communication module 30 establishes wireless communication with the wireless access point 46 and is connected to the wireless network 44.

[0044] Thereafter, the controller 36 executes tuner reception setting (an example of second setting) regarding the setting of the tuner 16 between the terminal device 8 (S109). After the tuner reception setting is completed, the power of the playback device 4 is turned off (S110).

[0045] Returning to step S105 described above, hereinafter, a case will be described in which the user performs an operation to interrupt the transmission of a connection request to the playback device 4 by the terminal device 8 that has received the beacon signal (NO in S105, YES in S111). In this case, the terminal device 8 that has received the beacon signal transmits an interruption request to the playback device 4. The first communications module 28 stops transmitting the beacon signal by receiving the interruption request from the terminal device 8 that has received the beacon signal (S112). Thereafter, the power of the playback device 4 is turned off (S110).

[0046] It should be noted that if the user does not perform an operation to interrupt the transmission of the connection request to the playback device 4 using the terminal device 8 that has received the beacon signal (NO in S111), the process returns to step S105 described above.

[0047] Returning to step S103 described above, when the power state of the display device 6 is the power-on state ("power-on state" in S103), the playback device 4 outputs an initial setting start screen to the display device 6 (S113). This initial setting start screen is generated by the graphics module 22, and is output to the display device 6 by the HDMI transmission unit 38. The user operates the remote control of the playback device 4 to perform various settings of the playback device 4 (S114). Specifically, the various settings of the playback device 4 include, for example, a) settings related to the remote control of the playback device 4, b) settings related to the connection of the display device 6, and c) settings to check whether the display device 6 is compatible with 4K / 60p.

[0048] After the various settings of the playback device 4 are completed, the playback device 4 outputs to the display device 6 an inquiry screen 52 for inquiring of the user as to whether or not to perform network settings using the terminal device 8 (S115). This inquiry screen 52 is generated by the graphic module 22, and output to the display device 6 by the HDMI transmission unit 38. As a result, the inquiry screen 52 as shown in FIG. 4(a), for example, is displayed on the display unit 14 of the display device 6. On the inquiry screen 52, for example, a message "Do you want to perform network settings on your smartphone?" is displayed along with a "Yes" button and a "No" button that can be selected.

[0049] If the user selects the “Yes” button on the inquiry screen 52 using the remote control of the playback device 4, i.e., if the user wishes to perform network settings using the terminal device 8 (YES in S116), the first communication module 28 transmits a beacon signal via BLE (S117).

[0050] At this time, the playback device 4 outputs to the display device 6 a guide screen 54 for prompting the user to operate the terminal device 8 (an operation for transmitting a connection request to the playback device 4) (S118). This guide screen 54 is generated by the graphic module 22, and output to the display device 6 by the HDMI transmission unit 38. As a result, the guide screen 54 as shown in FIG. 4(b), for example, is displayed on the display unit 14 of the display device 6. On the guide screen 54, for example, a message saying "Please make a connection request using your smartphone" is displayed together with a "Cancel" button that can be selected.

[0051] Thereafter, advertising by BLE is started, and the first communication module 28 enters a state of waiting for a connection request from the terminal device 8 (S105). Thereafter, each process of steps S105 to S112 is performed in the same manner as described above. Note that when the process proceeds from step S105 to step S111 and the user selects and operates the "Cancel" button on the guidance screen 54 with the remote control of the playback device 4, the process proceeds to step S112.

[0052] Furthermore, when the process proceeds from step S105 to step S106, the playback device 4 outputs to the display device 6 a guide screen 56 for prompting the user to operate the terminal device 8 to perform network settings and tuner reception settings. This guide screen 56 is generated by the graphic module 22, and is output to the display device 6 by the HDMI transmission unit 38. As a result, the guide screen 56 as shown in FIG. 4(c) is displayed on the display unit 14 of the display device 6. On the guide screen 56, for example, a message such as "Please operate on the smartphone to set up this unit" is displayed.

[0053] Furthermore, after step S109, the playback device 4 outputs a notification screen 58 to the display device 6 to notify the user that the initial settings have been completed. This notification screen 58 is generated by the graphics module 22, and output to the display device 6 by the HDMI transmission unit 38. As a result, the notification screen 58 as shown in FIG. 4(d), for example, is displayed on the display unit 14 of the display device 6. On the notification screen 58, a message such as "Settings have been completed. This unit will be turned off" is displayed, for example.

[0054] Returning to step S116 described above, if the user selects the "No" button on the inquiry screen 52 using the remote control of the playback device 4, that is, if the user does not wish to perform network settings using the terminal device 8 (NO in S116), the user operates the remote control of the playback device 4 to perform network settings on the screen displayed on the display device 6 (S119), and then performs tuner reception settings (S120). Then, the power of the playback device 4 is turned off (S110).

[0055] [1-4. Network setting flow] The flow of network setting between the playback device 4 and the terminal device 8 will be specifically described with reference to Figs. 5 to 10. Fig. 5 is a sequence diagram showing the flow of network setting between the playback device 4 and the terminal device 8 according to the embodiment. Fig. 6 is a diagram showing an example of a screen displayed on the terminal device 8 according to the embodiment. Fig. 7 is a diagram showing an example of a secret code displayed on the playback device 4 according to the embodiment. Figs. 8 to 10 are diagrams showing an example of a screen displayed on the terminal device 8 according to the embodiment.

[0056] The following describes the flow of network settings when the display device 6 connected to the playback device 4 is in a power-off state.

[0057] As shown in Fig. 5, first, the user operates the terminal device 8 to start an application installed in the terminal device 8 (S201). As a result, as shown in Fig. 6, a registration screen 60 is displayed on the terminal device 8 (S202). On the registration screen 60, a "Perform initial settings with smartphone" button is displayed selectably. When the user taps the "Perform initial settings with smartphone" button, the terminal device 8 enters a state of waiting for reception of a beacon signal from the playback device 4 (S203).

[0058] In addition, the user turns on the power of the playback device 4 (S204). Based on the control signal from the display device 6, the playback device 4 detects that the display device 6 is not in a power-on state (S205), and transmits a beacon signal by BLE (S206).

[0059] The terminal device 8 receives the beacon signal from the playback device 4 and transmits a connection request to the playback device 4 (S207). If the terminal device 8 does not receive the beacon signal from the playback device 4 even after a predetermined time has elapsed and a timeout occurs, the terminal device 8 displays a message such as "Cannot connect. Please turn off the recorder."

[0060] The playback device 4 receives a connection request from the terminal device 8 that has received the beacon signal (S208) and stops transmitting the beacon signal (S209). This establishes close proximity wireless communication by BLE between the playback device 4 and the terminal device 8 (S210, S211).

[0061] Thereafter, as shown in FIG. 7, the playback device 4 displays a secret code on the front panel display unit 10 (S212). The secret code is, for example, a four-digit number such as "1108." At this time, as shown in FIG. 8, a secret code input screen 62 is displayed on the terminal device 8. On the secret code input screen 62, for example, a message such as "Please enter the four-digit number displayed on the front panel of the recorder" is displayed along with a secret code input field and an input key. The user inputs the secret code displayed on the front panel display unit 10 of the playback device 4 on the secret code input screen 62 (S213). As a result, the terminal device 8 transmits the input secret code to the playback device 4 (S214).

[0062] The playback device 4 receives the personal identification code transmitted from the terminal device 8 and determines whether the received personal identification code is correct (S215). If the personal identification code is incorrect (NO in S215), the playback device 4 updates the personal identification code (S216) and displays the new updated personal identification code on the front panel display unit 10 (S212). If the personal identification code received is incorrect three times in total, the playback device 4 forcibly turns off the power.

[0063] The following describes the case where the secret code received by the playback device 4 is correct (YES in S215). The terminal device 8 requests the playback device 4 to transmit an AP (access point) list (S216). In response, the playback device 4 executes an AP scan to generate an AP list, and transmits the generated AP list to the terminal device 8 (S217).

[0064] The terminal device 8 receives the AP list from the playback device 4 (S218). At this time, as shown in Fig. 9, an AP list screen 64 is displayed on the terminal device 8 based on the received AP list. The AP list screen 64 displays, for example, the SSIDs "abcd012", "bbef034", "ccgh056", and "bcde123" of the wireless access points detected by the AP scan together with a message such as "Please select the same network as your smartphone".

[0065] The user selects, on the AP list screen 64, the SSID "abcd012" of the wireless access point 46 with which wireless communication has been established with the terminal device 8 (S219). As a result, as shown in FIG. 10, a passcode input screen 66 is displayed on the terminal device 8. On the passcode input screen 66, for example, a message "Please enter the passcode for abcd012" is displayed along with a passcode input field and a numeric keypad. The user inputs the passcode "xxxyyyy" for the SSID "abcd012" on the passcode input screen 66 (S219). As a result, the terminal device 8 transmits the SSID and passcode input by the user to the playback device 4 (S220).

[0066] The playback device 4 receives the SSID and passcode transmitted from the terminal device 8 (S221). As a result, the close proximity wireless communication between the playback device 4 and the terminal device 8 is disconnected (S222, S223), and the playback device 4 establishes wireless communication with the wireless access point 46 based on the received SSID and passcode (S224), and starts a connection to the wireless network 44.

[0067] Thereafter, the terminal device 8 searches for the playback device 4 via the wireless network 44 (S225), and connects to the playback device 4 via the wireless network 44 (S226). After that, tuner reception settings are made between the playback device 4 and the terminal device 8 as described below.

[0068] [1-5. Tuner reception setting procedure] A flow of tuner reception setting between the playback device 4 and the terminal device 8 will be specifically described with reference to Fig. 11 to Fig. 13. Fig. 11 is a sequence diagram showing the flow of tuner reception setting between the playback device 4 and the terminal device 8 according to the embodiment. Fig. 12 and Fig. 13 are diagrams showing examples of screens displayed on the terminal device 8 according to the embodiment.

[0069] When the playback device 4 is able to acquire the postal code information required for performing tuner reception setup from the display device 6, the playback device 4 performs tuner reception setup based on the postal code information acquired from the display device 6. The following describes a case where the playback device 4 is unable to acquire the postal code information from the display device 6. The postal code information is information indicating the postal code of the area where the playback device 4 is installed.

[0070] 11, the terminal device 8 instructs the playback device 4 to acquire postal code information via the wireless network 44 (S301). The playback device 4 attempts to acquire the postal code information from the display device 6 by CEC (S302), and notifies the terminal device 8 via the wireless network 44 of the failure to acquire the postal code information (S303).

[0071] The terminal device 8 receives the notification from the playback device 4 (S304) and judges whether or not there is another existing playback device (not shown) that has executed the tuner reception setting (S305). If there is no existing playback device (NO in S305), as shown in FIG. 12, a postal code input screen 68 is displayed on the terminal device 8. On the postal code input screen 68, for example, a message such as "Please enter the 7-digit postal code of your residence" is displayed along with a postal code input field and input keys. The user inputs the postal code of his / her residence area, for example, "571-8501", on the postal code input screen 68 (S306). As a result, the terminal device 8 transmits postal code information indicating the postal code input by the user to the playback device 4 (S307).

[0072] Returning to step S305 described above, if an existing playback device exists (YES in S305), the terminal device 8 acquires postal code information from the existing playback device via the wireless network 44 (S308). As a result, the terminal device 8 transmits the postal code information indicating the postal code acquired from the existing playback device to the playback device 4 (S307).

[0073] The reproducing device 4 receives the postal code information transmitted from the terminal device 8 (S309) and goes into a state of waiting for a channel scan instruction (S310). The terminal device 8 instructs the reproducing device 4 to perform a channel scan via the wireless network 44 (S311), and the reproducing device 4 sets the area from the received postal code information and starts a channel scan (S312). This causes the terminal device 8 to go into a state of waiting for the completion of the channel scan (S313). At this time, as shown in FIG. 13, a standby screen 70 indicating that the terminal device 8 is in a state of waiting for the completion of the channel scan is displayed on the terminal device 8. On the standby screen 70, for example, a message such as "Channel setting, terrestrial digital channel scanning in progress" is displayed along with a progress bar indicating the progress of the channel scan.

[0074] When the channel scan is completed, the playback device 4 transmits a completion notification to the terminal device 8 via the wireless network 44 to notify the terminal device 8 that the channel scan has been completed (S314). The terminal device 8 receives the completion notification transmitted from the playback device 4 (S315). In this manner, the tuner reception setting is completed.

[0075] [1-6. Effects] As described above, in this embodiment, the playback device 4 is a playback device that can be connected to the display device 6 and outputs a video signal to the display device 6. The playback device 4 includes an HDMI transmission unit 38 that detects the power state of the display device 6, a first communication module 28 that establishes communication with an external terminal device 8 when the HDMI transmission unit 38 does not detect that the display device 6 is in a power-on state, and a controller 36 that executes a first setting, which is a setting related to the playback device 4, between the terminal device 8 and the first communication module 28 when communication is established between the terminal device 8 and the first communication module 28.

[0076] According to this, when the HDMI transmission unit 38 does not detect that the display device 6 is in a power-on state, the first setting can be executed between the terminal device 8 and the first communication module 28 by establishing communication between the terminal device 8 and the first communication module 28. As a result, the first setting can be executed without using the display device 6, which improves user convenience.

[0077] In addition, in this embodiment, when the HDMI transmission unit 38 does not detect that the display device 6 is in a power-on state, the first communication module 28 transmits a beacon signal to the terminal device 8, and establishes communication with the terminal device 8 that receives the beacon signal.

[0078] This makes it possible to easily establish communication between the terminal device 8 and the first communication module 28 by using a beacon signal.

[0079] In the present embodiment, the playback device 4 further includes a remote control receiver 26 that receives a user's instruction. When the HDMI transmitter 38 detects that the display device 6 is in a power-on state and the remote control receiver 26 receives a user's instruction to perform the first setting using the terminal device 8, the first communication module 28 transmits a beacon signal to the terminal device 8 and establishes communication with the terminal device 8 that has received the beacon signal.

[0080] According to this, even if the HDMI transmission unit 38 detects that the display device 6 is in a power-on state, if the user wishes to perform the first setting using the terminal device 8, communication can be established between the terminal device 8 and the first communication module 28.

[0081] In this embodiment, the playback device 4 further includes a second communication module 30 for communicating with the wireless network 44. The first setting is a setting for connecting the playback device 4 to the wireless network 44 via the second communication module 30.

[0082] According to this, the terminal device 8 can be used to execute the first setting for connecting the reproduction device 4 to the wireless network 44 via the second communication module 30.

[0083] In this embodiment, the wireless network 44 is a wireless LAN. The first communication module 28 receives, from the terminal device 8, the SSID of a wireless access point 46 of the wireless LAN that the user inputs to the terminal device 8. The controller 36 executes the first setting based on the SSID received by the first communication module 28.

[0084] This allows the first setting to be executed based on the SSID inputted into the terminal device 8 by the user.

[0085] In this embodiment, the playback device 4 further includes a tuner 16 that receives broadcast waves. When the playback device 4 is connected to the wireless network 44, the second communication module 30 establishes communication with the terminal device 8 via the wireless network 44. When the controller 36 is able to acquire postal code information indicating the postal code of the area where the playback device 4 is installed from the display device 6, the controller 36 executes a second setting related to the setting of the tuner 16 based on the acquired postal code information. When the controller 36 is unable to acquire the postal code information from the display device 6, the second communication module 30 instructs the terminal device 8 via the wireless network 44 to acquire postal code information from another playback device that has executed the second setting.

[0086] According to this, even if the controller 36 is unable to acquire the postal code information from the display device 6, it is possible to cause the terminal device 8 to acquire the postal code information from another playback device that has executed the second setting.

[0087] Moreover, in this embodiment, the control method for the playback device 4 is a control method for the playback device 4 that is connectable to the display device 6 and outputs a video signal to the display device 6. The control method for the playback device 4 includes a step of detecting the power state of the display device 6, a step of establishing communication with an external terminal device 8 when it is not detected that the display device 6 is in a power-on state, and a step of executing a first setting between the terminal device 8 and the playback device 4 when communication between the terminal device 8 and the playback device 4 is established.

[0088] According to this, similarly to the above, the first setting can be performed without using the display device 6, and the convenience for the user can be improved.

[0089] Moreover, in this embodiment, the program causes a computer to execute the control method for the playback device 4 described above.

[0090] [1-7. Modifications] Next, a flow of network setting between the playback device 4 and the terminal device 8 according to the modified example of the embodiment will be described with reference to Fig. 14. Fig. 14 is a sequence diagram showing a flow of network setting between the playback device 4 and the terminal device 8 according to the modified example of the embodiment.

[0091] As shown in FIG. 14, in this modification, steps S216 to S219 described in FIG. 5 are replaced with steps S401 and S402.

[0092] If the answer is YES in step S215, the terminal device 8 requests an SSID and a passcode from another existing playback device (not shown) that has executed network settings via the wireless network 44 (S401), and receives the SSID and the passcode from the existing playback device (S402). After that, the terminal device 8 transmits the SSID and the passcode received from the existing playback device to the playback device 4 (S220).

[0093] In this modification, the wireless network 44 is a wireless LAN. The first communication module 28 receives, from the terminal device 8, the SSID of a wireless access point 46 of the wireless LAN that the terminal device 8 has acquired from another playback device for which the first setting has been executed. The controller 36 executes the first setting based on the SSID received by the first communication module 28.

[0094] This allows the terminal device 8 to execute the first setting based on the SSID acquired from another playback device that has executed the first setting. As a result, the user does not need to input the SSID and passcode, which improves user convenience.

[0095] (Variations, etc.) As described above, the above embodiment has been described as an example of the technology disclosed in this application. However, the technology in this disclosure is not limited to this, and can be applied to embodiments in which modifications, substitutions, additions, omissions, etc. are appropriately made. In addition, it is also possible to combine the components described in the above embodiment to create a new embodiment.

[0096] Therefore, other embodiments will be exemplified below.

[0097] In the above embodiment, the HDMI transmission unit 38 detects the power state of the display device 6, but when it detects that the display device 6 is in a power-off state, the display device 6 does not necessarily need to be connected to the playback device 4. In other words, when the display device 6 is not connected to the playback device 4, the HDMI transmission unit 38 cannot detect that the display device 6 is in a power-on state. In this case, the playback device 4 performs processing according to the following algorithm: i) confirms the HDMI connection state with the HDMI reception unit 50 and the power-on state of the display device 6, ii) directs the input of the display device 6 to the playback device 4 using a CEC command, iii) determines whether the input is directed to the playback device 4 using a CEC command, and iv) determines whether the display device 6 is in an Active Source state using a CEC command.

[0098] In the above embodiment, the reproducing device 4 is wirelessly connected to the wireless access point 46 by the second communication module 30, but the present invention is not limited to this. The reproducing device 4 may be wiredly connected to the wireless access point 46 by the wired LAN / IF 32. In this case, immediately before step S216 in the flowchart of FIG. 5, the terminal device 8 may display an inquiry screen for inquiring of the user whether to connect to the wireless access point 46 by wireless LAN or wired LAN. If the user selects the connection by wireless LAN, the controller 36 disables the wired LAN / IF 32 and enables the second communication module 30. In this case, the respective processes from step S217 in the flowchart of FIG. 5 onward are executed as described above. On the other hand, if the user selects the connection by wired LAN, the controller 36 enables the wired LAN / IF 32 and disables the second communication module 30. In this case, the processes in and after step S217 in the flowchart of FIG. 5 are not executed, a wired connection is established between the playback device 4 and the wireless access point 46, and the proximity wireless connection between the playback device 4 and the terminal device 8 is disconnected.

[0099] In the above embodiment, the close proximity wireless communication by BLE is established between the playback device 4 and the terminal device 8. However, instead of such a configuration, USB communication may be established between the playback device 4 and the terminal device 8. In this case, the terminal device 8 is connected to the USB I / F 34 via a USB cable, and the above-mentioned authentication process using a secret code is not required.

[0100] In the above embodiment, close proximity wireless communication by BLE is established between the playback device 4 and the terminal device 8. However, instead of this configuration, the playback device 4 may be in a parent mode (AP mode) and communicate directly (ad-hoc communication) with the terminal device 8 to set information about the wireless access point 46 from the terminal device 8. Thereafter, the playback device 4 may be changed to a child mode and connected to the wireless access point 46 by infrastructure communication.

[0101] In each of the above embodiments, each component may be implemented by dedicated hardware or by executing a software program suitable for each component. Each component may be implemented by a program execution unit such as a CPU or a processor reading and executing a software program recorded on a non-transitory recording medium such as a hard disk or a semiconductor memory.

[0102] Furthermore, some or all of the functions of the playback device 4 according to each of the above-described embodiments may be realized by a processor such as a CPU executing a program.

[0103] As described above, the embodiments have been described as examples of the technology in the present disclosure. For this purpose, the attached drawings and detailed description have been provided.

[0104] Therefore, among the components described in the attached drawings and detailed description, not only are there components essential for solving the problem, but there may also be components that are not essential for solving the problem in order to illustrate the above technology. Therefore, the fact that such non-essential components are described in the attached drawings or detailed description should not be interpreted as immediately indicating that such non-essential components are essential.

[0105] Furthermore, since the above-described embodiments are intended to illustrate the technology in the present disclosure, various modifications, substitutions, additions, omissions, and the like can be made within the scope of the claims or their equivalents. [Industrial Applicability]
