[0013] One embodiment of the present invention is described below. The referenced drawings are used to illustrate the technical features that the present invention may adopt. The configurations, controls, etc., shown in the drawings are not intended to limit the invention to those shown, but are merely illustrative examples.

[0014] The karaoke system 10 shown in Figure 1 is a commercial karaoke system installed, for example, in a karaoke establishment. The karaoke system 10 has the function of playing karaoke songs (hereinafter simply referred to as "songs") selected by the user, in conjunction with a video that includes lyrics. In this embodiment, the karaoke system 10 consists of a karaoke device 2 (sometimes called a commander) and a remote control device 1. The karaoke device 2 and the remote control device 1 are communicated together to form a network using a LAN 100 and an access point 130.

[0015] <Electrical configuration of karaoke machine 2> The karaoke device 2 comprises a control unit 20, a display video output terminal 21a, a sub-display video output terminal 21b, and an external video input terminal 22. The control unit 20 performs various processes, such as playing back music information and background video. The display video output terminal 21a, the sub-display video output terminal 21b, and the external video input terminal 22 are connected to the control unit 20. The display video output terminal 21a and the sub-display video output terminal 21b output video. A first monitor 41a is connected to the display video output terminal 21a, and a second monitor 41b is connected to the sub-display video output terminal 21b. In addition, external devices such as game consoles and DVD players can be connected to the external video input terminal 22, and the control unit 20 can capture the video. In this embodiment, as an example, terminals using the HDMI® standard are used for the display video output terminal 21a, the sub-display video output terminal 21b, and the external video input terminal 22.

[0016] In addition, the karaoke device 2 includes an interface 33, a mixing amplifier 34, a hard disk 35, an infrared communication unit 36, a wireless LAN communication unit 37, a LAN communication unit 38, and an operation unit 39. The mixing amplifier 34, the hard disk 35, the infrared communication unit 36, the wireless LAN communication unit 37, the LAN communication unit 38, and the operation unit 39 are connected to the control unit 20 via the interface 33.

[0017] The mixing amplifier 34 mixes the music sound played by the control unit 20 and the singing voice input from the microphones 43a and 43b, and outputs the result to the speaker 42. The infrared communication unit 36 communicates with the remote control device 1 and receives music selection and the like from the remote control device 1. The hard disk 35 stores various types of information. The LAN communication unit 38 functions as a communication means for connecting to the LAN 100 and joining the network. The operation unit 39 receives various inputs from the user. Further, the karaoke device 2 also includes a wireless LAN communication unit 37, and it is also possible to perform wireless network connection using the wireless LAN communication unit 37b instead of the wired network connection using the LAN communication unit 38.

[0018] Next, the configuration of the control unit 20 will be described with reference to FIGS. 2 and 3. FIGS. 2 and 3 show the configuration of the control unit 20. The control unit 20 includes a switching unit 23, a first SoC 24, a sub-switching unit 27, and a conversion unit 28. The switching unit 23 switches the video output from the first SoC 24 and the sub-switching unit 27, and outputs the result to the display video output terminal 21a or the sub-display video output terminal 21b.

[0019] The sub-switching unit 27 includes a video input terminal 272, a video output terminal 271a, and a video output terminal 271b. The sub-switching unit 27 switches and outputs the HDMI-standard video signal input from the external video input terminal 22 to the video input terminal 272 to the video output terminal 271a or the video output terminal 271b. The sub-switching unit 27 takes a first state in which the video input terminal 272 and the video output terminal 271b are connected, and a second state in which the video input terminal 272 and the video output terminal 271a are connected. Whether the sub-switching unit 27 takes the first state or the second state is controlled by the first SoC 24. The video signal output from the video output terminal 271b is converted into a CSI video signal with a resolution of 720p in the conversion unit 28 and input to the video capture terminal 242 of the first SoC 24. Note that the conversion unit 28 does not necessarily need to be provided depending on the format of the video signal to be used and the like.

[0020] The switching unit 23 includes a first display video input terminal 23a and a second display video input terminal 23d. The switching unit 23 outputs the video signal input from the first display video input terminal 23a or the second display video input terminal 23d to the display video output terminal 21a and / or the sub-display video output terminal 21b. The switching unit 23 takes a third state in which the first display video input terminal 23a is connected to the display video output terminal 21a and the sub-display video output terminal 21b, and a fourth state in which the second display video input terminal 23d is connected to the display video output terminal 21a and the sub-display video output terminal 21b. Whether the switching unit 23 takes the third state or the fourth state is controlled by the first SoC 24. In the present embodiment, the "capture setting" and "pass-through setting" described later can be switched. FIG. 2 shows the flow of the video signal during the capture setting (first video setting), and FIG. 3 shows the flow of the video signal during the pass-through setting (second video setting).

[0021] In the "Capture Settings" shown in Figure 2, the first SoC 24 controls the sub-switching unit 27 and the switching unit 23 so that the sub-switching unit 27 is in the first state and the switching unit 23 is in the third state. In the "Capture Settings," the video signal input to the external video input terminal 22 is captured by the first SoC 24 via the sub-switching unit 27 and the conversion unit 28. The first SoC 24 processes the captured video signal into an HDMI (registered trademark) video signal with a resolution of 4K, and then outputs the 4K video signal to the first display video input terminal 23a. The switching unit 23 outputs the video signal input from the first display video input terminal 23a to the display video output terminal 21a and / or the sub-display video output terminal 21b.

[0022] In the "pass-through setting" shown in Figure 3, the first SoC 24 controls the sub-switching unit 27 and the switching unit 23 so that the sub-switching unit 27 is in the second state and the switching unit 23 is in the fourth state. In the "pass-through setting," the video signal input to the external video input terminal 22 is input to the second display video input terminal 23d of the switching unit 23 via the sub-switching unit 27. The switching unit 23 outputs the video signal input from the second display video input terminal 23d to the display video output terminal 21a and / or the sub-display video output terminal 21b. In the capture setting, the video signal input to the external video input terminal 22 passes through the first SoC 24, whereas in the pass-through setting, the video signal input to the external video input terminal 22 does not pass through the first SoC 24. Therefore, in the pass-through setting, the video signal (external video) input to the external video input terminal 22 can be output to the display video output terminal 21a and / or the sub-display video output terminal 21b without delay. Therefore, with the pass-through setting, external video input to the external video input terminal 22 can be output without delay. For example, external video from a game console 6 input to the external video input terminal 22 can be output without delay, allowing for smooth gameplay on a large screen.

[0023] The first SoC24 is composed of an SoC (System on a Chip). The first SoC24 is a chip that integrates the functions necessary to control the karaoke machine 2, including a CPU243, RAM244, ROM245, etc. The first SoC24 is equipped with a video output terminal 241 and a video capture terminal 242. The first SoC24 can capture (acquire) the video signal output from the conversion unit 28 through the video capture terminal 242. The first SoC24 also processes the captured video signal into an HDMI video signal with a resolution of 4K. The video output terminal 241 outputs an HDMI video signal with a resolution of 4K. The video signal output from the video output terminal 241 is input to the first display video input terminal 23a of the switching unit 23. The first SoC24 is connected to the sub-switching unit 27 and the switching unit 23 by signal lines (not shown), and communicates with the sub-switching unit 27 and the switching unit 23 to control them.

[0024] The karaoke device 2 can perform various processes with the above configuration. Examples of the main processes performed by the karaoke device 2 include song reservation processing and song playback processing. Song reservation processing is the process of selecting and reserving a song based on the user's specifications and is performed in cooperation with the remote control device 1. The reservation information formed by the song selection process of the remote control device 1 is transmitted to the karaoke device 2. The karaoke device 2 registers the received reservation information in the reservation table in memory. Song playback processing is the process of playing the reserved song, and is a process in which the song playback process and the lyrics display process are executed synchronously.

[0025] <Electrical configuration of remote control device 1> Next, the remote control device 1 will be described with reference to Figure 1. The remote control device 1 includes a CPU 15 that controls the remote control device 1. The CPU 15 is connected to a video control unit 13, a memory 14, an operation processing unit 18, an infrared communication unit 19, and a wireless LAN communication unit 16. The memory 14 stores a database required for music selection processing, various programs, and various information generated during program execution. The video control unit 13 is connected to a video RAM 12, which temporarily stores the video information to be displayed. The video control unit 13 also forms the video to be displayed to the CPU 15 and the touch panel monitor 11.

[0026] The operation processing unit 18 is connected to the CPU 15, the touch panel monitor 11, or the operation unit 17, and interprets input from the touch panel monitor 11 or the operation unit 17 and transmits it to the CPU 15. The operation unit 17 and the touch panel monitor 11 function as a user interface that receives various instructions from the user. The touch panel monitor 11 is composed of a display unit 11a and a touch panel 11b.

[0027] The remote control device 1 is connected to the network configured by the LAN 100 by wirelessly connecting to the access point 130 via the wireless LAN communication unit 16. Each remote control device 1 is pre-associated with a specific karaoke machine 2. Various commands output from the remote control device 1 are received by the associated karaoke machine 2. In addition, the remote control device 1 of this embodiment is also equipped with an infrared communication unit 19, and it is possible to transmit various commands to the karaoke machine 2 using the infrared communication unit 19 instead of the wireless LAN communication unit 16. The transmitted commands are received by the infrared communication unit 19 of the karaoke machine 2 and input to the CPU 15.

[0028] With the above configuration, the remote control device 1 can receive various inputs from the user via the touch panel monitor 11 or the operation unit 17. Furthermore, by displaying video information on the touch panel monitor 11 and providing various information, the remote control device 1 can perform various processes, such as song selection processing, which sends reservation information to be output to the karaoke device 2.

[0029] The remote control device 1 is capable of performing song selection processing, which involves searching for songs based on user instructions and sending reservation information for the requested songs to the karaoke device 2. The remote control device 1 can also receive various information from the karaoke device 2 or an intermediary server (not shown) connected to the internet, and perform various processes. The access point 130 is connected to the network 100, which in turn connects to an external server device 5 via the internet, which distributes karaoke song data and background video. The server device 5 includes a storage unit 51, which stores karaoke song data and background video.

[0030] With this configuration of the remote control device 1, various inputs from the user are received from the touch panel monitor 11 or the operation unit 17, and various information is provided by displaying video information on the touch panel monitor 11, making it possible to perform various processes such as song selection processing, which sends reservation information to be output to the karaoke device 2. In this embodiment, using this configuration of the control unit 20, it is possible to output the video to be displayed from the display video output terminal 21a and the sub-display video output terminal 21b.

[0031] Karaoke machine 2 is configured so that the output setting for external video input can be set to "capture setting" or "passthrough setting" in the environment settings screen. In passthrough setting, external video input to external video input terminal 22 can be output without delay, so if you want to output the external video from game machine 6 without delay, it is desirable to use the passthrough setting. However, the environment settings screen is configured so that users of karaoke machine 2 cannot operate it. The environment settings screen is configured so that it can be operated when an administrator of a store or other establishment logs in with an administrator account. Therefore, even if a user of karaoke machine 2 wants to set the output setting for external video input to "passthrough setting", they cannot switch from capture setting to passthrough setting. In addition, various settings can be made in the environment settings screen, such as enabling / disabling the microphone and allowing / denying karaoke reservations.

[0032] The karaoke device 2 of this embodiment allows the user to easily change the output settings when an external video signal is input. This will be explained below.

[0033] (First Embodiment) Referring to the flowchart in Figure 4, the first control process performed in the first embodiment will be described. In the first embodiment, the CPU 243 built into the first SoC 24 performs the first control process. In the first embodiment, when the HDMI terminal 61 of the HDMI cable 60 of the game console 6 is connected to the external video input terminal 22, a process is performed to switch from capture setting to passthrough setting, and when the HDMI terminal 61 of the HDMI cable 60 of the game console 6 is disconnected from the external video input terminal 22 (becomes unconnected), a process is performed to switch back from passthrough setting to capture setting.

[0034] First, when the karaoke device 2 is powered on, in the first embodiment, the CPU 243 reads and executes a program for the first control process in addition to a program for performing karaoke from the ROM 245. In the first embodiment, the initial setting is set to capture. As shown in Figure 2, when the capture setting is enabled, the video signal input to the external video input terminal 22 is captured by the first SoC 24 via the sub-switching unit 27 and the conversion unit 28. The CPU 243 of the first SoC 24 processes the captured video signal into an HDMI video signal with a resolution of 4K, and then outputs the 4K video signal to the first display video input terminal 23a. The switching unit 23, under the control of the CPU 243, outputs the video signal input from the first display video input terminal 23a to the display video output terminal 21a and / or the sub-display video output terminal 21b.

[0035] In the first control process, the CPU 243 first determines whether it has detected the connection of an external device to the external video input terminal 22 when the karaoke is in the inter-song setting (waiting for playback) state (S11). In the first control process, if the CPU 243 detects the connection of an external device when the karaoke is not in the inter-song setting (waiting for playback) state, it may wait until the karaoke is in the inter-song setting (waiting for playback) state and then proceed to the process in S12. The CPU 243 detects the connection of the HDMI terminal 61 to the external video input terminal 22 via the sub-switching unit 27. If the CPU 243 does not detect the connection of the HDMI terminal 61 (S11:NO), it determines whether it has detected the connection of the HDMI terminal 61 at predetermined time intervals (S11).

[0036] When a user connects the HDMI terminal 61 of the game console 6 to the external video input terminal 22, information is sent from the HDMI terminal 61 to the CPU 243 of the karaoke machine 2 via the external video input terminal 22. Here, it is explained that the device connected to the external video input terminal 22 is the game console 6, but it may also be a video output device such as a DVD player. An example of the information sent is identification information that identifies the game console 6. When the CPU 243 receives identification information that identifies the game console 6 from the external video input terminal 22, it determines that it has detected a connection to the HDMI terminal 61 of the game console 6 (S11: YES). If the CPU 243 does not receive identification information that identifies the game console 6 from the external video input terminal 22, it does not determine that a connection has been detected to the HDMI terminal 61 of the game console 6 (S11: NO), and the determination process in S11 is repeated at regular intervals. When the CPU 243 determines that it has detected a connection to the HDMI terminal 61 of the game console 6 (S11: YES), it determines whether the identification information is for the game console that the karaoke machine 2 corresponds to (S12).

[0037] The CPU 243 determines whether the karaoke machine 2 is a compatible game machine (S12) by comparing it with a list of compatible game machines pre-stored in the ROM 245. If the CPU 243 determines that the received identification information is present in the list of compatible game machines, it determines that it is a compatible game machine (12: YES). If the CPU 243 does not determine that it is a compatible game machine (12: NO), it proceeds to S11 and repeats the determination process in S11 at regular intervals.

[0038] If the CPU 243 determines that it is a compatible game machine (12:YES), it performs the process of saving the current command settings (S13). As an example of the process of saving the current command settings (S13), the CPU 243 stores in the RAM 244 the settings for the karaoke machine 2 to perform karaoke, such as the microphone sound output setting, echo setting, built-in speaker output setting, and stereo / mono setting (S13). Before S14, it may be determined whether the output setting when an external video is input is set to the capture setting or the passthrough setting. In the first embodiment, it is set to the capture setting, so the CPU 243 then performs the game setting change process (passthrough setting) (S14). Specifically, if the output setting when an external video is input is set to the capture setting, the CPU 243 changes it from the capture setting to the passthrough setting. In addition, as part of the game setting change process (S14), the CPU 243 performs the process of disabling karaoke reservations and disabling microphone input.

[0039] Next, the CPU 243 performs a route change process (S15). The route change process (S15) changes the video signal flow path from the one shown in Figure 2 to the one shown in Figure 3. In the route change process (S15), the CPU 243 controls the sub-switching unit 27 and the switching unit 23 so that the sub-switching unit 27 is in the second state and the switching unit 23 is in the fourth state. As a result of the route change process (S15), the video signal input to the external video input terminal 22 is input to the second display video input terminal 23d of the switching unit 23 via the sub-switching unit 27. The video signal input from the second display video input terminal 23d is output to the display video output terminal 21a and / or the sub-display video output terminal 21b. Therefore, in the pass-through setting, the video signal (external video) input to the external video input terminal 22 can be output to the display video output terminal 21a and / or the sub-display video output terminal 21b without delay. Therefore, in the route change process (S15), the video signals output from the display video output terminal 21a and / or the sub-display video output terminal 21b are switched from the video signals output from the first SoC 24 to the output of the HDMI standard video signals input to the external video input terminal 22. As a result, the external video from the game console 6 input to the external video input terminal 22 is output to the first monitor 41a and / or the second monitor 41b without delay, allowing the game console 6 to be played smoothly on a large screen.

[0040] Next, the CPU 243 determines whether it has detected that no external device is connected to the external video input terminal 22 (S16). In this embodiment, the CPU 243 detects that the HDMI terminal of the game console 6 is disconnected. When the user disconnects the HDMI terminal 61 of the game console 6 from the external video input terminal 22, the CPU 243 stops receiving a signal from the HDMI terminal 61 and determines that it has detected that the HDMI terminal 61 is disconnected (S16: YES). Next, the CPU 243 performs commander setting restoration processing (S17). As commander setting restoration processing (S17), the CPU 243 reads the microphone sound output setting, echo setting, built-in speaker output setting, and stereo / mono setting stored in the RAM 244 during the command setting saving processing (S13) and sets the karaoke device 2 to operate with these settings. The CPU 243 also changes from pass-through setting to capture setting during commander setting restoration processing (S17). Furthermore, if CPU243 does not determine that HDMI port 61 is disconnected (S16:NO), it will perform HDMI disconnection detection at regular intervals (S16).

[0041] Next, the CPU 243 performs a commander setting restoration process (S17) followed by a route change process (S18). The route change process (S18) changes the video signal flow path from the pass-through setting shown in Figure 3 to the capture setting video signal flow path shown in Figure 2. In the route change process (S18), the CPU 243 controls the sub-switching unit 27 and the switching unit 23 so that the sub-switching unit 27 is in the first state and the switching unit 23 is in the third state. At the time the route change process (S18) is executed, no external device is connected to the external video input terminal 22, so no video signal is output from the display video output terminal 21a and / or the sub-display video output terminal 21b.

[0042] Next, the CPU 243 performs SoC video output processing (S19). As an example of SoC video output processing (S19), the CPU 243 plays the video for interludes stored on the karaoke machine's hard disk 35 (S19). Due to the route change processing (S18), the video signal flow path has been changed to that of the capture settings shown in Figure 2, so the video for interludes is output from the display video output terminal 21a and / or sub-display video output terminal 21b via the video output terminal 241 and first display video input terminal 23a of the first SoC 24. After that, the CPU 243 proceeds to S11 and repeats the above processing.

[0043] In the first embodiment, the case where the output setting for external video input is set to passthrough mode will be described. Before S14, it may be determined whether the output setting for external video input is set to capture mode or passthrough mode. If it is set to passthrough mode, in S14, as a game setting change process (S14), the karaoke reservation prohibition and microphone input prohibition processes are performed, but the passthrough setting is maintained. Also, as a commander setting restoration process (S17), the CPU 243 reads the microphone sound output setting, echo setting, built-in speaker output setting, and stereo / mono setting stored in RAM 244 in the command setting save process (S13) from RAM 244, and sets the karaoke device 2 so that it can operate with these settings. However, the CPU 243 maintains the passthrough setting during the commander setting restoration process (S17).

[0044] In the karaoke device 2 of the first embodiment, if the user connects the HDMI terminal 61 of the game console 6 to the external video input terminal 22, the CPU 243 performs a route change process (S15) if the game console is compatible (S12: YES). Consequently, the video signals output from the display video output terminal 21a and / or the sub-display video output terminal 21b are switched from the video signals output from the first SoC 24 to the output of the HDMI standard video signals input to the external video input terminal 22. As a result, the external video from the game console 6 input to the external video input terminal 22 is output to the first monitor 41a and / or the second monitor 41b without delay, allowing the game on the game console 6 to be played smoothly on a large screen.

[0045] (Second Embodiment) Referring to the flowchart in Figure 5, the second control process performed in the second embodiment will be described. In the second embodiment, the CPU 243 built into the first SoC 24 performs the second control process. In the second embodiment, first, when the user selects game mode A on the remote control device 1 via the touch panel monitor 11 or the operation unit 17, the CPU 15 of the remote control device 1 sends a notification of game mode A to the CPU 243 of the first SoC 24. The CPU 243 determines at regular intervals whether it has received the notification of game mode A (S31). In the second control process, the CPU 243 may determine that it has received the notification of game mode A when the karaoke song interval setting (waiting for playback) is active.

[0046] In the second control process, if the CPU 243 is not in the karaoke song interval setting (waiting for playback) state, and receives a notification for game mode A, it may wait until the karaoke song interval setting (waiting for playback) state is reached before proceeding to the process in S32. If the CPU 243 determines that it has received a notification for game mode A (S31: YES), it activates the no-compatible-game mode (S32). The no-compatible-game mode is a mode in which, regardless of whether or not the compatible game machine is listed in the list of compatible game machines pre-stored in the ROM 245 as being compatible with the karaoke device 2, if the output setting when external video is input is set to capture setting, a process is performed to change from capture setting to passthrough setting (S35).

[0047] First, when the karaoke device 2 is powered on, in the second embodiment, the CPU 243 reads and executes a program for the second control process in addition to the program for performing karaoke from the ROM 245. In the second embodiment, the initial setting is set to capture setting.

[0048] In the second control process, first, the CPU 243 determines whether it has received a notification of game mode A from the remote control device 1 via the infrared communication unit 36 ​​or the wireless LAN communication unit 37 when the karaoke song interval setting (waiting for playback) is enabled (S31). If the CPU 243 determines that it has received a notification of game mode A from the remote control device 1 (S31: YES), it activates the no-compatible-game mode (S32). The no-compatible-game mode is a mode in which, regardless of whether or not the compatible game machine is listed in the list of compatible game machines pre-stored in the ROM 245 as a compatible game machine for the karaoke device 2, if the output setting when external video is input is set to capture setting, it performs a process to change from capture setting to pass-through setting (S35). When the no-compatible-game mode is activated (S32), it determines whether the connection of the HDMI terminal 61 to the external video input terminal 22 has been detected (S33). The determination process in S33 is the same as the process in S11 of the first control process, so the explanation is omitted.

[0049] If the CPU 243 receives identification information for the game console 6 from the external video input terminal 22, it determines that the HDMI terminal 61 of the game console 6 has detected a connection (S33: YES). Next, the CPU 243 performs the current command setting save process without determining whether the identification information is for the game console that the karaoke device 2 corresponds to (S34). The current command setting save process (S34) is the same as the process in S13 of the first control process, so the explanation is omitted. If the determination process in S33 does not receive identification information for the game console 6 from the external video input terminal 22, it does not determine that the HDMI terminal 61 of the game console 6 has detected a connection (S33: NO), and the determination process in S33 is repeated at regular intervals.

[0050] CPU243, after the command setting save process (S34), performs a process to change to game mode A (S35). As an example of game mode A, CPU243 disables karaoke reservations and disables microphone input (S35). Also in S35, if the output setting for external video input is set to capture, CPU243 changes it from capture to passthrough. Therefore, karaoke cannot be played while game mode A is enabled. Next, CPU243 performs route change processing (S36). Route change processing (S36) is the same as the process in S15 of the first control process, so the explanation is omitted.

[0051] Next, the CPU 243 determines whether it has received a notification that the game mode has ended (S37). If the CPU 243 determines that it has received a notification that the game mode has ended (S37:YES), it performs the commander setting restoration process (S38). The commander setting restoration process (S38) is the same as the process in S17 of the first control process, so the explanation is omitted. Next, it performs the route change process (S39). The route change process (S39) is the same as the process in S18 of the first control process, so the explanation is omitted. Then, the CPU 243 performs the SoC video output process (S40). The SoC video output process (S40) is the same as the process in S19 of the first control process, so the explanation is omitted. After that, the CPU 243 proceeds to process S31 and repeats the above process.

[0052] In the karaoke device 2 of the second embodiment, if the CPU 243 determines that it has received a notification for game mode A (S31: YES), it starts the no-compatible-game mode (S32). Therefore, even if a game machine that is not listed in the list of compatible game machines pre-stored in the ROM 245 as a compatible game machine for the karaoke device 2 is connected to the external video input terminal 22, if the output setting for when external video is input is set to capture setting, it is possible to change the setting from capture setting to pass-through setting (S35). Consequently, the external video input from the game machine 6, which is not pre-stored in the ROM 245 as a compatible game machine for the karaoke device 2, to the external video input terminal 22 is output to the first monitor 41a and / or the second monitor 41b without delay, allowing the game machine 6 to be played smoothly. In the second embodiment, we will now describe the case where the output setting for external video input is set to passthrough. Before S35, it may be determined whether the output setting for external video input is set to capture or passthrough. If it is set to passthrough, the passthrough setting is maintained in S35. The passthrough setting is also maintained in S38. The other processing in S35 and S38 is the same as described above and will be omitted.

[0053] (Third embodiment) Referring to the flowchart in Figure 6, the third control process performed in the third embodiment will be described. In the third embodiment, the CPU 243 built into the first SoC 24 performs the third control process. First, when the karaoke device 2 is powered on, in the third embodiment, the CPU 243 reads and executes the program for the third control process in addition to the program for performing karaoke from the ROM 245. In the third embodiment, karaoke performance is possible even in game mode, and when karaoke performance is reserved, the karaoke video output from the video output terminal 241 of the first SoC 24 is output to the first monitor 41a and / or the second monitor 41b.

[0054] First, when the user selects game mode B on the remote control device 1 via the touch panel monitor 11 or the operation unit 17, the CPU 15 of the remote control device 1 sends a notification of game mode B to the CPU 243 of the first SoC 24. The CPU 243 determines at regular intervals whether it has received the notification of game mode B (S52). In the third control process, the CPU 243 may determine that it has received the notification of game mode B when it is in the karaoke song interval setting (waiting for playback) state. In the third control process, if the CPU 243 receives the notification of game mode B when it is not in the karaoke song interval setting (waiting for playback) state, it may wait until it becomes the karaoke song interval setting (waiting for playback) state and then proceed to the process in S53. If the CPU 243 determines that it has received the notification of game mode B (S52: YES), it activates the no-game mode (S53). The no-game mode (S53) is the same as the process in S32 of the second control process, so the explanation is omitted.

[0055] When CPU243 starts the no-game-compatible mode (S53), it determines whether it has detected the connection of the HDMI terminal 61 to the external video input terminal 22 (S54). The determination process in S54 is the same as the process in S11 of the first control process, so the explanation is omitted.

[0056] If the CPU 243 receives identification information for the game console 6 from the external video input terminal 22, it determines that the HDMI terminal 61 of the game console 6 has detected a connection (S54: YES). Next, without determining whether the identification information is for the game console that the karaoke device 2 corresponds to, the CPU 243 performs the current command setting save process (S55). The current command setting save process (S55) is the same as the process in S13 of the first control process, so the explanation is omitted. If the determination process in S54 does not receive identification information for the game console 6 from the external video input terminal 22, it does not determine that the HDMI terminal 61 of the game console 6 has detected a connection (S54: NO), and the determination process in S54 is repeated at regular intervals.

[0057] CPU243 currently performs the command setting save process (S55) followed by the process of changing to game mode B (S56). As an example of game mode B settings, CPU243 enables karaoke reservations and disables microphone input (S56). Therefore, karaoke reservations are possible even when game mode B is enabled. Also, in S55, if the output setting for when external video is input is set to capture, CPU243 changes it from capture setting to passthrough setting. Next, CPU243 performs route change processing (S57). Route change processing (S57) is the same as the processing in S15 of the first control processing, so the explanation is omitted.

[0058] Next, the CPU 243 determines whether a karaoke reservation has been made (S58). A karaoke reservation can be made from the remote control device 1, the karaoke device 2, or a smartphone with the karaoke application installed. If the CPU 243 determines that a karaoke reservation has been made (S58: YES), it accepts and prepares for the karaoke performance (S59). In the process of S59, the CPU 243 releases the restriction on microphone input, allows input from the microphone, and reads the song to be played from the hard disk 35. Next, the CPU 243 performs the commander setting restoration process (S60). The commander setting restoration process (S60) is the same as the process of S17 in the first control process, so the explanation is omitted. Next, the route change process (S61) is performed. The route change process (S61) is the same as the process of S18 in the first control process, so the explanation is omitted.

[0059] Next, the CPU 243 plays the karaoke music and reads the background video from the hard disk 35, outputting the karaoke video as SoC video to the first monitor 41a and / or the second monitor 41b (S62). Then, when the karaoke music is finished, the CPU 243 sets to inter-song mode (S63). Next, the CPU 243 performs a change to game mode B (S64). The process in S64 is the same as the process in S56, so the explanation is omitted. Next, the CPU 243 performs a route change process (S65). The route change process (S65) is the same as the process in S15 of the first control process, so the explanation is omitted.

[0060] The CPU 243 determines whether it has received a notification that the game mode has ended (S66). The determination process in S66 is the same as the determination process in S37 of the second control process, so the explanation is omitted. If the CPU 243 determines that it has received a notification that the game mode has ended (S66: YES), it performs the commander setting restoration process (S67). The commander setting restoration process (S67) is the same as the process in S17 of the first control process, so the explanation is omitted. Next, it performs the route change process (S68). The route change process (S68) is the same as the process in S18 of the first control process, so the explanation is omitted. Then, the CPU 243 performs the SoC video output process (S69). The SoC video output process (S69) is the same as the process in S19 of the first control process, so the explanation is omitted. After that, the CPU 243 proceeds to process S51 and repeats the above process.

[0061] In the third embodiment, the case where the output setting for external video input is set to passthrough will be described. Before S56, it may be determined whether the output setting for external video input is set to capture or passthrough. If it is set to passthrough, the passthrough setting is maintained in S56 and S64. The passthrough setting is also maintained in S67. The other processing in S56, S64 and S67 is the same as described above and will be omitted.

[0062] In the karaoke device 2 of the third embodiment, if the CPU 243 determines that it has received a notification for game mode B (S52: YES), it starts the no-compatible game mode (S53). Therefore, even if a game machine that is not listed in the list of compatible game machines pre-stored in the ROM 245 as a compatible game machine for karaoke device 2 is connected to the external video input terminal 22, if the output setting for when external video is input is set to capture setting, it is possible to change the setting from capture setting to passthrough setting (S56). Thus, external video input from a game machine 6 that is not pre-stored in the ROM 245 as a compatible game machine for karaoke device 2 is output to the first monitor 41a and / or the second monitor 41b without delay, allowing the game machine 6 to be played smoothly on a large screen. Furthermore, karaoke reservations and karaoke performances are possible even in game mode B. When a karaoke reservation is made, SoC video output processing is performed, and the karaoke video is output to the first monitor 41a and / or the second monitor 41b.

[0063] (Fourth Embodiment) Referring to the flowchart in Figure 7, the fourth control process performed in the fourth embodiment will be described. In the fourth embodiment, the CPU 243 built into the first SoC 24 performs the fourth control process. First, when the karaoke device 2 is powered on, in the fourth embodiment, the CPU 243 reads and executes the program for the fourth control process in addition to the program for performing karaoke from the ROM 245. In the fourth embodiment, karaoke performance is possible even in game mode. When karaoke performance is reserved, the game video is captured and the karaoke lyrics are combined into a video (SoC output) which is output to the first monitor 41a and / or the second monitor 41b. When karaoke performance is not in progress, the game video is passed through and output to the first monitor 41a and / or the second monitor 41b.

[0064] First, when the user selects game mode C on the remote control device 1 via the touch panel monitor 11 or the operation unit 17, the CPU 15 of the remote control device 1 sends a notification of game mode C to the CPU 243 of the first SoC 24. The CPU 243 checks at regular intervals whether it has received the notification of game mode C (S72). In the fourth control process, the CPU 243 may determine that it has received the notification of game mode C if it is in the karaoke song interval setting (waiting for playback) state. In the fourth control process, if the CPU 243 receives the notification of game mode C when it is not in the karaoke song interval setting (waiting for playback) state, it may wait until it becomes the karaoke song interval setting (waiting for playback) state and then proceed to the process in S73. If the CPU 243 determines that it has received the notification of game mode C (S72: YES), it activates the no-game mode (S73). The no-game mode (S73) is the same as the process in S32 of the second control process, so the explanation is omitted.

[0065] When CPU243 starts the no-game-compatible mode (S73), it determines whether it has detected the connection of the HDMI terminal 61 to the external video input terminal 22 (S74). The determination process in S74 is the same as the process in S11 of the first control process, so the explanation is omitted.

[0066] If the CPU 243 receives identification information for the game console 6 from the external video input terminal 22, it determines that the HDMI terminal 61 of the game console 6 has detected a connection (S74:YES). Next, the CPU 243 performs the current command setting save process without determining whether the identification information is for the game console that the karaoke device 2 corresponds to (S75). The current command setting save process (S75) is the same as the process in S13 of the first control process, so the explanation is omitted. If the determination process in S74 does not receive identification information for the game console 6 from the external video input terminal 22, it does not determine that the HDMI terminal 61 of the game console 6 has detected a connection (S74:NO), and the determination process in S74 is repeated at regular intervals.

[0067] CPU243 currently performs the command setting save process (S75) followed by the process of changing the game mode to C (S76). As an example of the game mode C setting, CPU243 enables karaoke reservations and disables microphone input (S76). Therefore, karaoke reservations are possible even when game mode C is enabled. Also in S76, if the output setting for when external video is input is set to capture, CPU243 changes it from capture setting to passthrough setting. Next, CPU243 performs the route change process (S77). The route change process (S77) is the same as the process in S15 of the first control process, so the explanation is omitted.

[0068] Next, the CPU 243 determines whether a karaoke reservation has been made (S78). Note that karaoke reservations can be made from the remote control device 1, the karaoke device 2, or a smartphone with the karaoke application installed. If the CPU 243 determines that a karaoke reservation has been made (S78: YES), it accepts and prepares for the karaoke performance (S79). In the process of S79, the CPU 243 releases the restriction on microphone input, allows input from the microphone, and reads the song to be played from the hard disk 35. Next, the CPU 243 performs the commander setting restoration process (S80). The commander setting restoration process (S80) is the same as the process of S17 in the first control process, so the explanation is omitted. Next, the CPU 243 performs the route change process (S81). The route change process (S81) is the same as the process of S18 in the first control process, so the explanation is omitted.

[0069] Next, the CPU 243 captures game video from the external video input terminal 22 and creates a background image by combining the captured game video with karaoke lyrics (S82). Next, the CPU 243 plays the karaoke song and outputs the background image created by combining the game video captured in S82 with the karaoke lyrics, and this background image is output to the first monitor 41a and / or the second monitor 41b (S83). Then, when the karaoke performance is finished, the CPU 243 sets to inter-song mode (S84). Next, the CPU 243 performs a change process to game mode C (S85). The process in S85 is the same as the process in S76, so the explanation is omitted. Next, the CPU 243 performs a route change process (S86). The route change process (S86) is the same as the process in S15 of the first control process, so the explanation is omitted.

[0070] The CPU 243 determines whether it has received a notification that the game mode has ended (S87). The determination process in S87 is the same as the determination process in S37 of the second control process, so the explanation is omitted. If the CPU 243 determines that it has received a notification that the game mode has ended (S87:YES), it performs the commander setting restoration process (S88). The commander setting restoration process (S88) is the same as the process in S17 of the first control process, so the explanation is omitted. Next, it performs the route change process (S89). The route change process (S89) is the same as the process in S18 of the first control process, so the explanation is omitted. Then, the CPU 243 performs the SoC video output process (S90). The SoC video output process (S90) is the same as the process in S19 of the first control process, so the explanation is omitted. After that, the CPU 243 proceeds to process S71 and repeats the above process.

[0071] In the fourth embodiment, we will now describe the case where the output setting for external video input is set to passthrough. Before S76, it may be determined whether the output setting for external video input is set to capture or passthrough. If it is set to passthrough, the passthrough setting is maintained in S76 and S85. The passthrough setting is also maintained in S80 and S88. The other processing in S76, S85, S80, and S88 is the same as described above and will be omitted.

[0072] In the karaoke device 2 of the fourth embodiment, if the CPU 243 determines that it has received a notification for game mode C (S72: YES), it starts the no-compatible-game mode (S73). Therefore, even if a compatible game machine is not listed in the list of compatible game machines pre-stored in the ROM 245 as being compatible with the karaoke device 2, if the output setting for when external video is input is set to capture setting, it can change from capture setting to pass-through setting (S76). Consequently, external video input to the external video input terminal 22 from a game machine 6 that is not pre-stored in the ROM 245 as being compatible with the karaoke device 2 can be output to the first monitor 41a and / or the second monitor 41b without delay, allowing the game machine 6 to be played smoothly on a large screen. Furthermore, karaoke reservations and karaoke performances are possible even in game mode C. Furthermore, the CPU 243 captures game footage from the external video input terminal 22 and creates a background image by combining the captured game footage with karaoke lyrics (S82). The CPU 243 then performs the karaoke and outputs the background image created by combining the game footage captured in S82 with karaoke lyrics, which can then be output to the first monitor 41a and / or the second monitor 41b (S83).

[0073] As described above, in the above embodiment, when the external device connected to the external video input terminal 22 is a specific external device, or when an instruction to use a specific external device is received from the remote control device 1, which is a reservation terminal, a video change process or audio change process corresponding to the specific external device can be performed. Furthermore, when a change process is performed, the first video setting and the first audio setting are stored in the memory unit, so the first video setting and the first audio setting can be easily restored. In addition, it is possible to allow or prohibit audio input from the microphone. Furthermore, at least one of the settings for the output of the sound input from the microphone, the echo setting, the output setting of the speaker built into the karaoke device, and the stereo or mono setting of the playback sound can be set as the first audio setting, so that a variety of functions of the karaoke device can be set. In addition, the change process can be executed when it is determined that the external device connected to the external video input terminal is a specific external device. Therefore, the video signal input from the specific external device can be output to the output terminal. Furthermore, the original setting can be returned by disconnecting the connection between the external video input terminal and the external device. The original setting can be returned when an instruction to end a specific mode is received. Furthermore, the system can prioritize and process changes based on the received instruction for a specific mode. The specific mode can be set to one of the following: Game Mode A (First Game Setting), Game Mode B (Second Game Setting), or Game Mode C (Third Game Setting).

[0074] In the above embodiment, the display video output terminal 21a and the sub-display video output terminal 21b are examples of "output terminals" of the present invention. The CPU 243 is an example of a "processor" of the present invention. The game console 6 is an example of an "external device" of the present invention.

The setting that prohibits audio input from the microphone is an example of the "second audio setting" of the present invention. The judgment processing in S12 of the first control processing is an example of the "external device judgment processing" of the present invention. Game mode A is an example of the "first game mode" of the present invention. Game mode B is an example of the "second game mode" of the present invention.

In the above embodiments, a game console 6 was used as an example of an external device, but the external device is not limited to a game console, and various terminal devices such as personal computers, tablet terminals, and smartphones can be used. The first display unit and the second display unit are not limited to monitors, and a touch panel monitor may be used as either the first display unit or the second display unit. In the present invention, only one of the monitors may be connected as the display unit. In addition, multiple remote control devices 1 may be provided to the karaoke device 2.

[0077] In the first to fourth embodiments described above, the display video output terminal 21a and the sub-display video output terminal 21b are used to output to two monitors, the first monitor 41a and the second monitor 41b. However, the output of the switching unit 23 is not limited to two systems as described above; it may have one output system, or it may have three or more outputs. Furthermore, when the first monitor 41a and the second monitor 41b are connected to the switching unit 23, the video signal input from the external video input terminal 22 may be output to one monitor, and a video signal pre-stored by the karaoke device 2 may be output to the other. In this case, the first monitor 41a and the second monitor 41b can output the video signal from the game machine 6 input from the external video input terminal 22 to one monitor, and the karaoke background video signal pre-stored by the karaoke device to the other monitor.

[0078] In the second to fourth embodiments described above, the commander settings are restored (S38, S67, S88) in the second to fourth control processes upon receiving a game mode termination notification (S37:YES, S66:YES, S87:YES). However, the commander settings may also be restored upon detection that the HDMI terminal 61 is not connected to the external video input terminal 22. [Explanation of Symbols]
