Modes for Carrying Out the Invention

[0020] FIG. 1 is a diagram showing the configuration of the karaoke system of the present embodiment. The karaoke system in the present embodiment includes a karaoke device 2 (sometimes also called a commander) and a remote control device 1. In the present embodiment, the karaoke device 2 and the remote control device 1 are communicatively connected to the LAN 100 by wire or wirelessly to form a network.

[0021] The karaoke device 2 installed in a store such as a karaoke box is provided with a sound processing unit 25 that plays music (accompaniment). The sound processing unit 25 of the present embodiment includes sound quality adjustment units 25a and 25b that apply effects such as echo to the voice signals input from the microphones 43a and 43b, a playback unit 25c that plays music, and an addition unit 25d that adds the voice signal with the effect applied and the playback signal of the music. The signal added by the addition unit 25d is output to the speaker 42. In FIG. 1, for the sake of convenience, the speaker 42 is shown as one, but it is possible to adopt various forms such as using a plurality of speakers 42 for stereo output or surround output.

[0022] The karaoke device 2 of the present embodiment is configured by connecting various devices via the interfaces 22a to 22d. In FIG. 1, four interfaces 22a to 22d are used, but the forms of the interfaces 22a to 22d can adopt various forms such as making them one or providing them for each device.

[0023] The karaoke device 2 includes an operation unit 21 that receives various inputs from the user. The karaoke device 2 also includes a hard disk 32 as a storage unit that stores various information. The karaoke device 2 includes a LAN communication unit 24a as a communication means for connecting to the LAN 100 and joining the network. Further, the karaoke device 2 of the present embodiment also includes a wireless LAN communication unit 24b, and it is also possible to perform a wireless network connection using the wireless LAN communication unit 24b instead of the wired network connection using the LAN communication unit 24a.

[0024] In addition, the karaoke device 2 includes a video playback unit that causes the monitor 41 to display lyrics videos, background videos, and the like. The video playback unit includes a video formation unit 29 that plays back videos based on video data, a video RAM 28 that temporarily stores the played-back videos, and a video control unit 31 that performs superimposition of lyrics videos on the played-back videos, application of video effects, and the like. These video playback units may be provided as a video card configured as one device.

[0025] Furthermore, in this karaoke device 2, in addition to the monitor 41 connected externally, it is possible to display various information on the touch panel monitor 33. The touch panel monitor 33 includes a display unit 35 that displays the video input from the video control unit 31, and a touch panel 34 that outputs the position where a touch input is made to the interface 22b. The touch panel monitor 33 of the present embodiment is arranged on the front surface of the housing of the karaoke device 2 or the like, and functions as an input unit that receives various operations from the user. The user can perform various operations on the karaoke device 2, such as directly reserving a song on the karaoke device 2 by selecting a song on the touch panel monitor 33.

[0026] Furthermore, the karaoke device 2 is configured to include a control unit that includes a CPU 30 for overall control of each component and a memory 27 for temporarily storing information necessary for executing various programs.

[0027] The karaoke device 2 of the present embodiment is configured to have a USB terminal 36 to which a USB device 44 can be connected. Examples of the USB device 44 include an expansion unit that adds functions to the karaoke device 2. In addition, the karaoke device 2 is provided with a power supply 37 that supplies power to each component. In the present embodiment, the power supply 37 is also one of the devices constituting the karaoke device 2, and different manufacturers or different types may be used depending on the production period of the karaoke device 2 or the like.

[0028] With such a configuration, the karaoke device 2 will execute various processes. As the main functions of the karaoke device 2, it can execute processes such as music reservation processing and playback processing. The music reservation processing is a process for designating and reserving a music based on a designation from a user, and is executed in cooperation with the remote control device 1. The reservation information formed by the music selection processing 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 the memory 27. The playback processing is a process for playing back the reserved music, and is a process in which the performance processing, the lyrics display processing, and the video playback processing are executed synchronously.

[0029] The performance processing is a process for causing the playback unit 25c to execute a performance based on the performance data included in the music data. The music played by the playback unit 25c is mixed in the addition unit 25d with the audio signals input from the microphones 43a and 43b and is emitted from the speaker 42. The lyrics display processing is a process for assisting singing by displaying a lyrics video based on the lyrics data included in the music data on the monitor 41. It is also possible to execute a background video display processing for superimposing and displaying a background video on the lyrics video displayed in this lyrics display processing.

[0030] On the other hand, the remote control device 1 can execute a music selection process for searching for a music based on an instruction from a user and transmitting reservation information for the music with a playback instruction to the karaoke device 2. Further, the remote control device 1 can receive various information from the karaoke device 2 or the server device 5 connected to the Internet and execute various processes. In the present embodiment, as a user interface for receiving various instructions from a user, it includes an operation unit 17 and a touch panel monitor 11. The touch panel monitor 11 is configured to have a display unit 11a and a touch panel 11b, and while displaying various information on the display unit 11a, it can receive a touch input from a user.

[0031] Furthermore, the remote control device 1 includes a memory 14 as a storage unit for storing databases, various programs, and various information generated during program execution that are required for the music selection process, and a remote control side control unit for comprehensively controlling these components. The remote control side control unit includes a CPU 15, a video control unit 13 for forming a video to be displayed on the touch panel monitor 11, a video RAM 12 for temporarily storing video data of the video to be displayed, and an operation processing unit 18 for interpreting inputs from the touch panel monitor 11 or the operation unit 17 and transmitting them to the CPU 15.

[0032] The remote control device 1 is wirelessly connected to the access point 130 by the wireless LAN communication unit 16 and thus connected to the network constituted by the LAN 100. Each remote control device 1 is pre-associated with a specific karaoke device 2. Various commands output from the remote control device 1 will be received by the associated karaoke device 2.

[0033] With such a configuration of the remote control device 1, it is possible to perform various processes such as a music selection process for transmitting reservation information output to the karaoke device 2 by receiving various inputs from the user from the touch panel monitor 11 or the operation unit 17 and providing various information by the display on the touch panel monitor 11.

[0034] As described above, the karaoke device 2 is configured to have various devices connected to the interfaces 22a to 22d. In such a situation, even if the product type and the manufacturing date are the same, the devices configured for each product may be different. Also, even for the same product type, the types of devices configured may be different depending on different manufacturing dates. In such a situation, the applicant has newly found that the characteristics of the sound output from the speaker 42 change slightly depending on the connection status of the device that makes some electrical connection to the karaoke device 2.

[0035] On the one hand, in a karaoke device, it is necessary to have good sound quality to enjoy karaoke. However, the change in the characteristics of sound output depending on the connection status of the device is not preferable in a karaoke device that requires good sound quality. Also, it is not preferable that the characteristics of sound output vary from product to product.

[0036] Therefore, in the present embodiment, the connection status of the devices in the karaoke device 2 is judged, and based on the judged connection status of the devices, the parameters used in the sound processing unit 25 are set, so as to suppress the change in sound output for each product and provide good sound.

[0037] Note that the devices targeted in the present embodiment refer to devices other than the sound processing unit 25 that are not directly involved in the sound processing of the built-in devices in the main body such as the hard disk 32, the memory 27, the video card, the display unit 35, various communication units (infrared communication unit 23, LAN communication unit 24a, wireless LAN communication unit 24b, etc.), the power supply 37, or external devices such as the USB device 44, and devices that are not directly involved in the sound processing of the audio signal input from the microphones 43a, 43b or the playback signal output from the playback unit 25c.

[0038] In the present embodiment, the devices for judging the connection status are the hard disk 32 and the wireless LAN communication unit 24b, and the connection status is the type of the hard disk 32 and the setting status of the wireless LAN (enabled setting or disabled setting). The targeted devices and their connection status are not limited to this example, and it is possible to target various devices other than the sound processing unit 25 used in the karaoke device 2 and their connection status. As the connection status, various forms such as the presence or absence of device connection, the type of the connected device, and the enabled / disabled setting of the connected device can be considered.

[0039] In addition, as parameters of the sound processing unit 25 set according to the connection status of the device, parameters used for sound quality adjustment of the sound quality adjustment units 25a and 25b are used. The parameters in the sound processing unit 25 are not limited to this example, and include parameters related to the volume in the sound quality adjustment units 25a and 25b, or the sound quality or volume used in the playback unit 25c, or the volume in the addition unit 25d, etc. Various parameters related to the sound quality or volume emitted from the speaker 42 used in the sound processing unit 25 can be targeted singly or in plural.

[0040] FIG. 2 is a flowchart showing the startup process of the karaoke device 2 of the present embodiment. In the present embodiment, at the time of startup processing when power is turned on for the karaoke device 2, determination of the connection status of the device and setting of parameters for the sound processing unit 25 are performed. In addition, as devices to be the determination target of the connection status as described above, the hard disk 32 and the wireless LAN communication unit 24b are used.

[0041] When power is supplied to the karaoke device 2, the startup process shown in FIG. 2 is executed. In the startup process, startup of various components constituting the karaoke device 2 is performed (S101). In the present embodiment, setting information indicating the usage environment is stored in a storage unit such as the memory 27, and based on the setting information, various components are started up. The setting information includes setting of whether or not to use the wireless LAN communication unit 24b (on / off), and based on this setting, the wireless LAN communication unit 24b is set to on or off (S102). Note that the setting information can be set by an operation on the operation unit 21 or a remote operation from the server device 5 when the karaoke device 2 is in use (at startup).

[0042] Next, the karaoke device 2 acquires SMART information (Self-Monitoring, Analysis and Reporting Technology) from the hard disk 32 (S103). The SMART information is various information regarding each individual hard disk 32, and in the present embodiment, information regarding the type of the hard disk is used from among the SMART information.

[0043] Based on the determination of the connection status of the wireless LAN communication unit 24b (device on / off setting) in S102 and the determination of the hard disk connection status (device type) in S103, the parameters used by the sound processing unit 25 are determined.

[0044] FIG. 3 is a diagram showing various lists used in this embodiment. FIG. 3(A) is a hard disk type discrimination list, and FIG. 3(B) is a parameter discrimination list. These lists are stored in the memory 27 of the karaoke device 2 or the hard disk 32. Further, these lists can be updated and added by maintenance by the administrator or distribution from the server device 5, and can cope with changes in the specifications of the devices of the karaoke device 2.

[0045] Based on the hard disk type discrimination list shown in FIG. 3(A), the hard disk type is discriminated based on the information regarding the type of the hard disk in the SMART information read from the hard disk 32. In this embodiment, it is assumed that two types of hard disks 32 are used as shown in FIG. 3(A). Regarding the parameters, as shown in FIG. 3(B), four types of parameters A to D are set according to whether the wireless LAN setting is on / off and the type of the two types of hard disks 32. These parameters A to D are values adjusted by the manufacturer for each connection status of the device, and are values that can ensure good sound quality in the sound processing unit 25 for each connection status of each device.

[0046] FIG. 4 is a diagram for explaining the parameters (for one band) used in the present embodiment. The parameters of the present embodiment are values for changing the frequency characteristics of the sound quality adjustment units 25a and 25b in the sound processing unit 25. These parameters are values for controlling the frequency characteristics of the sound quality adjustment units 25a and 25b that function as parametric equalizers, and for each band, it is possible to adjust the center frequency f, the gain G, and the adjustment width Q. By applying the parameters for three bands to each of the sound quality adjustment units 25a and 25b, it is possible to perform sound quality adjustment on the audio signals input to the microphones 43a and 43b. Also, by varying the parameters used depending on the connection status of the device, it is possible to achieve good sound quality or keep the sound quality constant even when the connection status of the device is different.

[0047] In the startup process, when the wireless LAN communication unit 24b is set to on (S104: Yes) and the hard disk 32 is of Type A (S105: Type A), parameter A is acquired based on the parameter discrimination list (S107). Similarly, when the wireless LAN communication unit 24b is set to on (S104: Yes) and the hard disk 32 is of Type B (S105: Type B) based on the parameter discrimination list, parameter B is acquired (S107). When the wireless LAN communication unit 24b is set to off (S104: No) and the hard disk 32 is of Type A (S108: Type A), parameter C is acquired (S109). When the wireless LAN communication unit 24b is set to off (S104: No) and the hard disk 32 is of Type B (S105: Type B), parameter D is acquired (S110).

[0048] Parameters obtained based on the connection status of the device are set in the sound processing unit 25 (in this embodiment, the sound quality adjustment units 25a and 25b) and are used to adjust the sound quality output from the speaker 42. Thus, in this embodiment, by changing the parameters used in the sound processing unit 25 based on the connection status of the device, even when the type of hard disk (manufacturer, manufacturing date, capacity, etc.) or the on / off setting of the wireless LAN communication unit 24b is different, it is possible to make the sound output characteristics from the speaker 42 good.

[0049] FIG. 5 is a flowchart showing the reproduction process of this embodiment. The parameters set in the sound processing unit 25 in the startup process are used in the reproduction process in the karaoke device 2. The reproduction process is a process of reproducing music data, and in this embodiment, the music is reproduced in the order reserved in the reservation process.

[0050] In the reservation process (not shown), based on the user's operation, the identification information of the music is registered in the reservation table. In the reproduction process, the reservation table is checked (S101), and then the presence or absence of the next music to be reproduced is confirmed (S102). If there is the next music to be reproduced (S102: Yes), the music data corresponding to the identification information of the next music to be reproduced is read (S103), and the reproduction of the music data is started (S104). At that time, for the audio signals input from the microphones 43a and 43b, sound quality adjustment based on the parameters set in the startup process is performed in the sound quality adjustment units 25a and 25b, and the sound output to the speaker is executed (S105). When the reproduction of the music data is completed (S106: Yes), the process returns to the beginning of the reproduction process, and the reservation table is checked (S101).

[0051] As described above, in this reproduction process, sound quality adjustment is performed based on the parameters set in the sound processing unit 25 (specifically, the sound quality adjustment units 25a and 25b). At that time, in the startup process, parameters corresponding to the connection status of the device are set, so the sound output from the speaker 42 is suitable for the connection status of the device.

[0052] <First Modification Example> As described above, in the foregoing embodiment, in the startup process, it is possible to determine the connection status of the device and perform a playback process using parameters suitable for the connection status of the device. By the way, among the devices for which the connection status is to be determined, in addition to those that do not change or are unlikely to change during the startup of the karaoke device 2, such as the type of the hard disk 32 or the on / off setting of the wireless LAN communication unit 24b, as in the foregoing embodiment, there are also devices that can be easily changed during startup, such as the USB device 44.

[0053] In the first modification process, the determination of the connection status of the device is not only performed at startup but also for each playback process of each music piece. FIG. 6 is a flowchart showing the playback process according to another embodiment (first modification example). It is different from the flowchart of the playback process in FIG. 5 in that S111 to S114 are added. Here, S111 to S114, which are the differences, will be described.

[0054] In the playback process of FIG. 5, the connection status of the device is determined at the startup of the karaoke device 2, and the corresponding parameters are set in the sound processing unit. In the first modification example, during the playback process, before the start of playback of a music piece, the change in the connection status of the device is monitored. If there is a change in the connection status of the device (S111: Yes), for example, if a new USB device 44 is connected (or removed, etc.), the connection status of the device is determined (S112), the parameters corresponding to the determined connection status are read (S113), and the read parameters are set in the sound processing unit 25 (S114).

[0055] As described above, in the first modification example, since parameters corresponding to the connection status of the device are used for each playback of the music data, even if the connection status of the device changes during the startup of the karaoke device 2, it is possible to use the parameters corresponding to the connection status and perform suitable sound output. Also, during the playback of the music data, since the parameters are not changed, the sound quality does not change during playback.

[0056] In the first modification example, the connection status of the device is determined and parameters are set before the start of reproduction of music data. However, the timing of determining the connection status of the device and setting the parameters can be appropriately timed outside the reproduction period of the music data (such as at the end of reproduction of the music data). Alternatively, it may be performed in a section other than the singing section during music reproduction (introduction, interlude, coda).

[0057] Also, the determination of the connection status of the device and the setting of the parameters may be performed in both the startup process and the reproduction process. In that case, it is possible to use different devices for determining the connection status in the startup process and the reproduction process, or a common device may be used as the determination target between the two.

[0058] <Second Modification Example> In the above-described embodiment, parameters related to the sound quality (specifically, frequency characteristics) of the audio signals input to the microphones 43a and 43b are the setting targets. The parameters to be used are not limited to such a form. For example, parameters related to the reproduction sound of music data in the reproduction unit 25c may be used, or parameters related to sound quality adjustment for the sound signal added in the addition unit 25d, etc. As long as they are parameters used in the sound processing unit 25 and are used for the sound output from the speaker 42, various types can be adopted.

[0059] <Third Modification Example> As described in the above embodiment, the parameters according to the connection status of the device are stored in a storage unit such as the memory 27 and the hard disk 32 in a form such as the parameter discrimination list in FIG. 3(B). After the release of the karaoke device 2, it is conceivable that the specifications of the devices used in the karaoke device 2 change, or that a new USB device 44 that can be used in the karaoke device 2 is newly added. Alternatively, it is also conceivable that the appropriate parameters change due to the availability of new devices.

[0060] Therefore, it is preferable that parameters (parameter discrimination list) according to the connection status of the device can be added or changed. The addition and change of the parameter discrimination list can be performed, for example, externally by an administrator using the USB terminal 36 during maintenance, or by distribution from the server device 5.

[0061] <Fourth Modification Example> In the above-described embodiment, four types of parameters A to D according to the type of the hard disk 32 and on / off (two types) of the wireless LAN communication unit 24b are used. Thus, in the above-described embodiment, the parameters set in the sound processing unit 25 are according to combinations of connection statuses of a plurality of devices.

[0062] The connection status of the device to be determined is not limited to two types as in the above-described embodiment, and it is conceivable to be one type or three or more types. For example, in the case of three types, by preparing nine types of parameters according to three types of combinations (nine patterns), it is possible to perform sound output suitable for the combination.

[0063] As described above, various embodiments have been described. However, the present invention is not limited to the karaoke device 2, and can be executed on various information processing devices (personal computers, game machines, smartphones, etc.), and a karaoke program that realizes the karaoke device 2 according to the present invention when executed, or a parameter setting method for a karaoke device that sets parameters in the karaoke device 2 also belongs to the scope thereof.
