[0011] <Embodiment> A karaoke system according to an embodiment will be described with reference to FIGS.

[0012] ==Karaoke System== A karaoke system is a system for singing karaoke. The karaoke system includes a karaoke machine and multiple remote control devices. The karaoke machine is a device for performing karaoke songs. The remote control devices are devices for performing various operations on the karaoke machine.

[0013] Among the multiple remote control devices, one remote control device is paired with the karaoke device. By pairing the karaoke device with the one remote control device, the one remote control device can communicate with the karaoke device. The one remote control device is, for example, placed in the same karaoke room as the karaoke device. There may be multiple one remote control devices.

[0014] Pairing can be performed using known techniques. For example, one remote control device obtains the device identification information and IP address of the karaoke device from the karaoke device and creates pairing information including its own IP address. The one remote control device then transmits communication information to the karaoke device that associates the pairing information with its own device identification information. The karaoke device completes pairing with the one remote control device by storing the IP address of the one remote control device included in the received pairing information in a storage means.

[0015] On the other hand, among the multiple remote control devices, the other remote control devices are not paired with any karaoke device. The other remote control devices are spare remote control devices. The other remote control devices are, for example, placed at the front desk of the karaoke store. There may be multiple other remote control devices.

[0016] As shown in FIG. 1, the karaoke system 1 according to this embodiment includes a karaoke device K and two remote control devices (remote control device R1 and remote control device R2). The karaoke device K and the remote control device R1 are placed in a karaoke room KR. The remote control device R1 is paired with the karaoke device K. Meanwhile, the remote control device R2 is placed at the front desk F. In this embodiment, the remote control device R1 corresponds to the "one remote control device," and the remote control device R2 corresponds to the "other remote control device."

[0017] ==Remote Control Device R1== 2, the remote control device R1 includes a first storage unit R10, a communication unit R11, a display unit R12, an input unit R13, a rechargeable battery R14, and a control unit R15. Each component is connected to a bus B via an interface (not shown).

[0018] [First storage means, communication means, display means, input means, rechargeable battery] The first storage means R10 is a large-capacity storage device that stores various data. The first storage means R10 stores history information (described later). The communication means R11 provides an interface for connecting the remote control device R1 and the karaoke device K. The display means R12 is configured to display various screens, such as a song search screen. The input means R13 is configured to allow the user to input various operations. The rechargeable battery R14 is configured to store power to operate the remote control device R1, such as a lithium-ion battery.

[0019] [Control means] The control means R15 performs various controls on the remote control device R1. The control means R15 includes a CPU and a memory (neither of which are shown). The CPU executes programs stored in the memory to realize various functions.

[0020] In this embodiment, the control means R15 functions as a first storage processing unit 100, a determination unit 200, and a remote control side transmission processing unit 300 by the CPU executing a program stored in the memory.

[0021] (First storage processing unit) The first storage processing unit 100 stores the history information in the first storage means R10.

[0022] The history information is a history of various operations performed on the remote control device and information obtained as a result of the operations. The history information includes at least one of the following: user identification information of the user who logged in to the karaoke system, an operation history showing the history of the user's operations on the remote control device, and song identification information of the song for which a karaoke performance has been reserved.

[0023] User identification information is information unique to each user, such as a user ID for identifying the user. A known method can be used to log in to the karaoke system. For example, a user operates the remote control device R1, enters their user identification information and password, and then selects the login icon. The password is used when logging in and is set in advance by the user.

[0024] The remote control device R1 transmits a login request including the input user identification information and password to a server device (not shown). The server device stores the user identification information and password included in the received login request in a storage means, thereby completing the login to the karaoke system 1. The server device transmits a signal indicating that the login has been completed to the remote control device R1. The first storage processing unit 100 stores the user identification information of the logged-in user in a first storage means R10.

[0025] The user can also operate the remote control device R1 to select a song to sing karaoke. In this case, the first storage processing unit 100 stores the operations performed by the user via the remote control device R1 in association with the song selection as an operation history in the first storage means R10.

[0026] The remote control device R1 can also transmit song identification information for a song selected by the user to the karaoke device K to reserve a karaoke performance. Song identification information is information unique to each song, such as a song ID for identifying the song. The first storage processing unit 100 stores the song identification information of the song reserved for karaoke performance in the first storage means R10.

[0027] The first storage processing unit 100 updates the history information stored in the first storage means R10 every time one of the above operations is executed.

[0028] For example, if there are multiple users, the first storage processing unit 100 updates the history information by storing the user identification information of one user in the first storage means R10 each time that user logs in.

[0029] Also, for example, suppose that a user performs a series of operations via the remote control device R1 in the order of "select search icon," "select singer name," and "input singer name." In this case, the first storage processing unit 100 stores the operation of "select search icon" in the first storage means R10 as an operation history. Next, the first storage processing unit 100 stores the operation of "select singer name" in the first storage means R10, and finally stores the operation of "input singer name" in the first storage means R10, thereby updating the history information.

[0030] Also, for example, when multiple songs are selected, the first storage processing unit 100 updates the history information by storing the song identification information of a song in the first storage means R10 each time a song is selected.

[0031] When a karaoke performance of a certain song is reserved, the first storage processing unit 100 can delete the operation history when the certain song was selected from the history information.

[0032] (Judgment Department) The determination unit 200 determines whether the remaining capacity of the rechargeable battery R14 included in the remote control device R1 is equal to or less than a predetermined value.

[0033] The predetermined value is a value that takes into consideration the possibility that the remote control device may become completely unusable, and is set to a predetermined value, such as 15% when a full charge is 100%.

[0034] The determination process can be performed at a predetermined timing. For example, the determination unit 200 determines every five minutes whether the remaining capacity of the rechargeable battery R14 is equal to or less than a predetermined value. If it determines that the remaining capacity of the rechargeable battery is equal to or less than the predetermined value, the determination unit 200 outputs the determination result to the remote control transmission processing unit 300. On the other hand, if it determines that the remaining capacity of the rechargeable battery is greater than the predetermined value, the determination unit 200 does not output the determination result to the remote control transmission processing unit 300.

[0035] If it is determined that the remaining capacity of the rechargeable battery is equal to or less than a predetermined value, the determination unit 200 can display an alert on the display means R12 indicating that the remaining capacity of the rechargeable battery is low. A user who sees this alert can contact the front desk and request a replacement of the remote control device. Based on this request, the staff member will deliver a new remote control device to the karaoke room KR where the karaoke device K is located. Alternatively, if it is determined that the remaining capacity of the rechargeable battery is equal to or less than a predetermined value, the determination unit 200 can send a signal to the front desk terminal requesting a replacement of the remote control device. Based on this signal, the front desk terminal notifies the staff member that the remote control device needs to be replaced. Based on this notification, the staff member will deliver a new remote control device to the karaoke room KR where the karaoke device K is located.

[0036] (Remote control side transmission processing unit) The remote control side transmission processing unit 300 transmits the history information stored in the first storage means R10 to the karaoke device K when the remaining capacity of the rechargeable battery falls below a predetermined value.

[0037] When a judgment result is output from the judgment unit 200 (i.e., when the remaining capacity of the rechargeable battery is less than a predetermined value), the remote control side transmission processing unit 300 transmits the history information stored in the first storage means R10 at that time to the karaoke device K.

[0038] After transmitting the history information to the karaoke device K, the remote control transmission processing unit 300 can prohibit the use of the remote control device R1 (for example, by turning off the power or erasing the various icons displayed on the display means R12).

[0039] ==Karaoke Machine K== As shown in FIG. 3, the karaoke device K includes a karaoke main unit 10, a speaker 20, a display device 30, and a microphone 40.

[0040] The karaoke unit 10 performs various controls related to karaoke performance and singing, such as controlling the karaoke performance of the selected song, controlling the display of lyrics and background images, and processing audio signals input through the microphone 40. The speaker 20 is configured to emit sound based on the sound emission signal from the karaoke unit 10. The display device 30 is configured to display videos and images on a screen based on the signal from the karaoke unit 10. The microphone 40 is configured to convert the singing voice of the user singing karaoke into an analog audio signal and input it to the karaoke unit 10.

[0041] 4, the karaoke machine 10 according to this embodiment includes a second storage means 10a, a communication means 10b, an input means 10c, a performance means 10d, and a control means 10e. Each component is connected to a bus B via an interface (not shown).

[0042] [Second storage means] The second storage means 10a is a large-capacity storage device that stores various types of data. The second storage means 10a stores music data.

[0043] The song data includes song identification information. The song data includes accompaniment data, reference data, etc. The accompaniment data is the data that forms the basis of the karaoke performance sound. The reference data is data that indicates the singing melody of the song performed by the karaoke user and is used to evaluate the karaoke singing of the user.

[0044] The second storage means 10a stores lyric data for displaying lyrics corresponding to each song on the display device 30 or the like in sync with the karaoke performance, background image data such as background images to be displayed on the display device 30 or the like during the karaoke performance, and attribute information of the song (song name, singer name, genre, performance time, etc.).

[0045] [Communication means / input means] The communication means 10b provides an interface for communicating with each remote control device. The input means 10c is configured to allow the user to input various operations. The input means 10c is a button or the like provided on the karaoke main unit 10.

[0046] [Means of performance] Based on the control of the control means 10e, the performance means 10d performs karaoke performance of music pieces and processes audio signals input through the microphone 40. The performance means 10d includes a sound source, a mixer, an amplifier, etc. (none of which are shown).

[0047] [Control means] The control means 10e performs various controls in the karaoke device K. The control means 10e includes a CPU and a memory (neither of which is shown). The CPU executes programs stored in the memory to realize various functions.

[0048] In this embodiment, the CPU executes a program stored in the memory, so that the control means 10e functions as a second storage processing unit 400 and a karaoke side transmission processing unit 500.

[0049] (Second storage processing unit) The second storage processing unit 400 stores the history information transmitted from one remote control device in the second storage means 10a.

[0050] For example, when history information transmitted from remote control device R1 is received, second storage processing section 400 stores the history information in second storage means 10a.

[0051] (Karaoke side transmission processing unit) When the karaoke side transmission processing unit 500 is paired with another remote control device different from the one remote control device, it transmits the history information stored in the second storage means 10a to the other remote control device.

[0052] For example, if karaoke device K and remote control R1 are paired (see FIG. 1), and the remaining capacity of the rechargeable battery R14 of remote control R1 becomes low, the employee delivers remote control R2 from the front desk F to the karaoke room KR. The employee operates remote control R2 to pair karaoke device K with remote control R2. Remote control R2 obtains device identification information and the IP address of karaoke device K from karaoke device K and creates pairing information including its own IP address. Remote control R2 transmits communication information that associates its own device identification information with the pairing information to karaoke device K. Karaoke device K completes pairing with remote control R2 by storing the IP address of remote control R2 included in the received pairing information in second storage means 10a (see FIG. 5). The employee takes remote control R1 back to the front desk and charges it. At this time, karaoke device K can cancel the pairing between remote control R1 and karaoke device K.

[0053] When the remote control device R2 and the karaoke device K are paired, the karaoke side transmission processing unit 500 transmits the history information stored in the second storage means 10a at that time (i.e., the history information transmitted from the remote control device R1) to the remote control device R2.

[0054] ==Remote Control Device R2== 6, the remote control device R2 includes a third storage means R20, a communication means R21, a display means R22, an input means R23, a rechargeable battery R24, and a control means R25. Each component is connected to a bus B via an interface (not shown).

[0055] [Third storage means, communication means, display means, input means, rechargeable battery] The third storage means R20 is a large-capacity storage device that stores various types of data. The third storage means R20 stores history information transmitted from the karaoke device K. The communication means R21, display means R22, input means R23, and rechargeable battery R24 have the same configurations as the communication means R11, display means R12, input means R13, and rechargeable battery R14 of the remote control device R1, respectively, and therefore detailed description thereof will be omitted.

[0056] [Control means] The control means R25 performs various controls on the remote control device R2. The control means R25 includes a CPU and a memory (neither of which are shown). The CPU executes programs stored in the memory to realize various functions.

[0057] In this embodiment, the control means R25 functions as a third storage processing unit 600 by the CPU executing a program stored in the memory.

[0058] (Third storage processing unit) The third storage processor 600 stores the history information transmitted from the karaoke device K in the third storage means R20.

[0059] When the karaoke device K and the remote control device R2 are paired, the karaoke device K (the karaoke side transmission processing unit 500) transmits the history information stored in the second storage means 10a to the remote control device R2. The third storage processing unit 600 stores the received history information in the third storage means R20.

[0060] ==About Karaoke System 1 Operation== Next, a specific example of the operation of the karaoke system 1 in this embodiment will be described with reference to Fig. 7. Fig. 7 is a flowchart showing an example of the operation of the karaoke system 1. In this example, the karaoke system 1 is assumed to have a karaoke device K paired with a remote control device R1, and a remote control device R2 placed at the front desk F, as shown in Fig. 1. Also, assume that a user U uses the karaoke device K in a karaoke room KR.

[0061] The first storage processing section 100 of the remote control device R1 stores the history information in the first storage means R10 (storing the history information; step 10).

[0062] The determination unit 200 determines at a predetermined timing whether the remaining capacity of the rechargeable battery R14 is equal to or less than a predetermined value.

[0063] When the remaining capacity of the rechargeable battery R14 falls below a predetermined value (step 11), the remote control side transmission processing unit 300 transmits the history information stored in the first storage means R10 to the karaoke device K (transmitting history information; step 12).

[0064] The second storage processing unit 400 of the karaoke device K stores the history information transmitted from the remote control device R1 in the second storage means 10a (stores the history information; step 13).

[0065] If the remote control device R1 is paired with a different remote control device R2 (Y in step 14), the karaoke side transmission processing unit 500 transmits the history information stored in the second storage means 10a to the remote control device R2 (transmitting history information; step 15).

[0066] The third storage processing unit 600 of the remote control device R2 stores the history information transmitted from the karaoke device K in the third storage means R20 (stores history information; step 16).

[0067] Specifically, user U operates remote control device R1, inputs his / her user ID ***U and password PW, and then selects the login icon. Remote control device R1 sends a login request including the input user ID ***U and password PW to the server device. The server device completes login to the karaoke system 1 by storing the user ID ***U and password PW included in the received login request. The server device sends a signal to remote control device R1 indicating that login has been completed.

[0068] The first storage processing unit 100 stores the user ID ***U of the user U as the history information HI in the first storage means R10.

[0069] The user U then operates the remote control device R1 to select the song they wish to sing karaoke. First, as a first operation, the user U selects the "singer name search icon" displayed on the display unit R12. The remote control device R1 causes the display unit R12 to display the 50 hiragana characters for searching for singer names. Next, as a second operation, the user U selects "i" from the hiragana characters displayed on the display unit R12. Similarly, as a third operation, the user U selects "ru" from the hiragana characters displayed on the display unit R12, as a fourth operation, the user U selects "ma" from the hiragana characters displayed on the display unit R12, and as a fifth operation, the user U selects "i" from the hiragana characters displayed on the display unit R12. Then, as a sixth operation, the user U selects the "search execution icon" displayed on the display unit R12. The remote control device R1 causes the display unit R12 to display the singer name "Iruma Isu" corresponding to the selected character. As a seventh operation, the user U selects the displayed singer name. The remote control device R1 causes the display means R12 to display a list of songs corresponding to the singer's name "Iruma Isu." As an eighth operation, the user U selects song X from the song list. Finally, as a ninth operation, the user U selects the "reservation icon" displayed on the display means R12.

[0070] The first storage processing unit 100 stores the operation history from the first operation to the ninth operation as history information HI in the first storage means R10. Specifically, the first storage processing unit 100 stores the first operation as the operation history in the first storage means R10. Then, every time the second operation to the ninth operation are performed, the first storage processing unit 100 stores the operation history in the first storage means R10, thereby updating the history information.

[0071] When song X is selected as described above, remote control device R1 transmits song ID ***X of song X to karaoke device K to reserve a karaoke performance.

[0072] The first storage processing unit 100 stores the song ID ***X of the song X as history information HI in the first storage means R10.

[0073] With the history information HI (user ID ***U, operation history from the first operation to the ninth operation, and song ID ***X) stored in the first storage means R10, it is assumed that the determination unit 200 determines that the remaining capacity of the rechargeable battery R14 is equal to or less than a predetermined value. In this case, the determination unit 200 outputs the determination result to the remote control side transmission processing unit 300.

[0074] The remote control side transmission processing section 300 transmits the history information HI stored in the first storage means R10 to the karaoke device K.

[0075] The second storage processor 400 of the karaoke device K stores the history information HI transmitted from the remote control device R1 in the second storage means 10a.

[0076] In this example, the determination unit 200 transmits a signal to the terminal at the front desk F requesting the replacement of remote control R1. Based on the signal, the terminal at the front desk F notifies the staff member that remote control R1 needs to be replaced. Based on the notification, the staff member delivers remote control R2 to the karaoke room KR. The staff member operates remote control R2 to pair the karaoke device K with remote control R2.

[0077] When the karaoke device K is paired with the remote control device R2, the karaoke side transmission processing unit 500 transmits the history information HI stored in the second storage means 10a to the remote control device R2.

[0078] The third storage processing unit 600 stores the history information HI transmitted from the karaoke device K in the third storage means R20.

[0079] As is clear from the above, the karaoke system 1 according to this embodiment includes a karaoke device K and remote controls R1 and R2. The remote control R1, which is paired with the karaoke device K, includes a first storage processor 100 that stores history information in a first storage unit R10, the history information including at least one of user identification information of a user who has logged in to the karaoke system 1, an operation history indicating a history of operations performed on the remote control R1 by the user, and song identification information of songs for which karaoke performances have been reserved; a determination unit 200 that determines whether the remaining capacity of a rechargeable battery R14 included in the remote control R1 is equal to or less than a predetermined value; and a remote control transmission processor 300 that transmits the history information stored in the first storage unit R10 to the karaoke device K when the remaining capacity of the rechargeable battery R14 becomes equal to or less than the predetermined value. The karaoke device K has a second storage processor 400 that stores history information transmitted from the remote control device R1 in the second storage means 10a, and a karaoke-side transmission processor 500 that transmits the history information stored in the second storage means 10a to the remote control device R2 when the karaoke device K is paired with a remote control device R2 different from the remote control device R1. The remote control device R3 has a third storage processor 600 that stores history information transmitted from the karaoke device K in the third storage means R20.

[0080] According to the karaoke system 1, when the remaining charge of the rechargeable battery of the remote control device R1 paired with the karaoke device K becomes low, the history information stored in the remote control device R1 is transmitted to the karaoke device K and temporarily stored there. Then, when the karaoke device K is paired with the remote control device R2 (a remote control device with sufficient remaining charge of the rechargeable battery), the karaoke device K transmits the stored history information to the remote control device R2. By storing the received history information in the remote control device R2, the user can use the remote control device R2 in the same state as immediately before the replacement. Therefore, there is no need to re-perform operations such as entering user identification information or selecting songs that have already been performed on the remote control device R1. In other words, the karaoke system 1 according to this embodiment reduces the stress experienced by the user when replacing one remote control device with another.

[0081] Furthermore, when a karaoke performance of a certain song is reserved, the first storage processor 100 can delete the operation history when selecting the certain song from the history information. With this karaoke system 1, history information including only information required for other remote control devices can be stored.

[0082] <Variation 1> In the processing by the determination unit 200, for example, the predetermined value may be "15% where 100% is a full charge." In this case, the remote control device R1 can be used even after the determination unit 200 determines that the remaining capacity of the rechargeable battery is equal to or less than the predetermined value. Therefore, new history information may be generated.

[0083] Therefore, the remote control transmission processor 300 can transmit new history information obtained after transmitting the history information to the karaoke device K. The remote control transmission processor 300 transmits new history information to the karaoke device K every time it obtains new history information.

[0084] Moreover, the second storage processing unit 400 adds new history information to the history information stored in the second storage means 10a and stores the new history information.

[0085] For example, in the embodiment, history information HI is stored in second storage means 10a. Now, suppose that song ID ***Y of song Y is transmitted as new history information from remote control side transmission processing section 300. In this case, second storage processing section 400 updates history information HI and adds and stores song ID ***Y.

[0086] As is clear from the above, in the karaoke system 1 according to this modification, the remote control transmission processor 300 transmits new history information obtained after transmitting the history information to the karaoke device K, and the second storage processor 400 adds the new history information to the history information stored in the second storage means 10a and stores it. According to this karaoke system 1, all history information obtained by one remote control device can be stored in the karaoke device K. In other words, all history information can be stored in other remote control devices.

[0087] <Variation 2> The third storage processing unit 600 according to this modification can reproduce processing based on the operation history in the remote control device R2 when the operation history is included in the history information stored in the third storage means R20.

[0088] For example, in the example embodiment, the history information HI includes an operation history from the first operation to the ninth operation. In this case, the third storage processing unit 600 refers to the history information HI stored in the third storage means R20, and reproduces the first operation to the ninth operation in order on the display means R22. Note that, for example, if the history information includes an operation history from the first operation to the fifth operation (i.e., an operation history up to immediately before a song search is performed), the third storage processing unit 600 refers to the history information and reproduces the first operation to the fifth operation in order on the display means R22.

[0089] As is clear from the above, in the karaoke system 1 according to this modification, when the history information stored in the third storage means R20 includes an operation history, the third storage processing unit 600 can reproduce the process based on the operation history on another remote control device. By reproducing the process based on the operation history in this way, the user can reconfirm the operation that he or she performed on one remote control device.
