Description

The present invention relates to a karaoke device.

Conventionally, karaoke devices are equipped with numerous karaoke contents, such as voice training contents to improve the user's singing ability, pitch evaluation contents, and contents that evaluate singing techniques such as fisting and vibrato.

However, among the many karaoke contents installed on karaoke devices, some are frequently performed by users, while other karaoke contents, such as older karaoke contents that have been installed for some time, are less frequently performed by users.

As a technology for promoting the use of karaoke content that is performed infrequently, Patent Document 1 discloses a technology that compares the frequency of each karaoke content with a specified value, and for karaoke content whose frequency of performance is equal to or lower than the specified value, displays an advertisement video for that karaoke content during the intervals between songs.

JP 2012-118287 A

However, while conventional technologies such as Patent Document 1 can promote the use of karaoke content whose execution frequency is below a specified value, the condition for determining which karaoke content to display advertising information for is only the aggregated execution frequency result, and it is not possible to take into account songs that the user has currently reserved or is currently singing. In other words, conventional technologies cannot recommend old and infrequently performed karaoke content according to the user's song reservation status.

The object of the present invention is to provide a karaoke device that can recommend old and infrequently played karaoke content based on the user's song reservation status.

To solve the above problem, the karaoke device of the present invention is a karaoke device that can use multiple karaoke contents, and is characterized by having an acquisition unit that acquires the delivery year in which karaoke performance data of a reserved song was delivered to the karaoke device, a first identification unit that identifies the karaoke content that was available on the karaoke device in the delivery year acquired by the acquisition unit as a first candidate, and a recommendation unit that recommends the karaoke content to a user based on the first candidate identified by the first identification unit.

According to the present invention, it is possible to recommend karaoke content that is old and not frequently performed, based on the user's song reservation status.

Fig. 1 is a block diagram showing the configuration of a karaoke system 100 including a karaoke device 1 according to an embodiment. As shown in Fig. 1, the karaoke system 100 includes a karaoke device 1, a server device 101, and a mobile terminal 102. The karaoke device 1 includes a karaoke main unit 2, a display device 3 such as a monitor, a speaker 4, a microphone 5, and a remote control device 6. The karaoke device 1 according to this embodiment has a function of providing a user with karaoke performance of a selected (reserved) song, as well as a function of providing a user with karaoke content selected from among a plurality of karaoke contents.

For example, the karaoke device 1 is installed in an installation location such as a karaoke room, the server device 101 is installed somewhere other than the installation location, and the mobile terminal 102 is owned by a user of the karaoke device 1. The karaoke device 1 is connected to the server device 101 and the mobile terminal 102 so as to be able to communicate with each other via a predetermined network (not shown).

[Server device]
The server device 101 has a function of managing the distribution of karaoke performance data of songs to the karaoke device 1, and for example, when new karaoke performance data is added, the server device 101 distributes the karaoke performance data to the karaoke device 1. The server device 101 stores the year in which the karaoke performance data of a song was distributed to the karaoke device 1 (hereinafter referred to as the distribution year) in a song distribution year table. For example, when the karaoke performance data is distributed to the karaoke device 1, the server device 101 transmits the song distribution year table to the karaoke device 1. For example, as shown in Fig. 2, the song distribution year table stores song titles, song identification information (song IDs), and distribution years for each of the many songs distributed to the karaoke device 1 in association with each other.

The server device 101 also has a function of managing the operation of karaoke content on the karaoke device 1, and provides, for example, newly added karaoke content to the karaoke device 1. The server device 101 stores a content start year table of the year in which operation of the karaoke content started (hereinafter referred to as the start year). For example, when new karaoke content is added and operation starts, the server device 101 transmits the content start year table to the karaoke device 1. For example, as shown in FIG. 3, the content start year table stores karaoke content identification information (content ID) and start year for each of the multiple karaoke contents installed in the karaoke device 1 in association with each other.

[Mobile devices]
The mobile terminal 102 is composed of a smartphone or tablet terminal owned by the user. The mobile terminal 102 is capable of communication by being paired with the karaoke machine 1. The mobile terminal 102 may be equipped with an application for using the karaoke machine 1, and may have the same functions as the remote control device 6 by using this application. For example, the mobile terminal 102 can display various screens provided to the user by the karaoke machine 1 and input various information to the karaoke machine 1 by using this application.

[Karaoke equipment]
In the karaoke device 1, a karaoke main unit 2 is connected to a display device 3, a speaker 4, a microphone 5, and a remote control device 6 by wire or wirelessly.

The display device 3 displays various screens provided to the user by the karaoke device 1, and for example displays lyrics subtitles along with background images in sync with the karaoke performance based on a video signal or the like from the karaoke main unit 2. The speaker 4 outputs the music and audio provided to the user by the karaoke device 1, and for example emits the user's singing voice along with the sound of the music being played based on a sound emission signal from the karaoke main unit 2. The microphone 5 converts the user's singing voice into an audio signal and inputs it to the karaoke main unit 2.

The remote control device 6 is mainly composed of a touch panel. The remote control device 6 displays on its touch panel various screens and various operation buttons that the karaoke device 1 provides to the user, and also accepts login operations and song selection (reservation) operations via the touch panel. By pairing the remote control device 6 and the karaoke main unit 2, various information can be transmitted and received between the remote control device 6 and the karaoke main unit 2.

The remote control device 6 transmits the user ID and other information input in response to the user's login operation to the karaoke main unit 2. The remote control device 6 accepts song selection (reservation) by searching for songs or selecting recommended songs, and links the song ID of the song selected (reserved) in response to the user's song selection (reservation) operation with the user ID of the user and transmits it to the karaoke main unit 2 as reserved song information. The remote control device 6 also accepts the selection of karaoke content, and links the content ID of the karaoke content selected in response to the user's selection operation with the user ID of the user and transmits it to the karaoke main unit 2. For example, the remote control device 6 accepts the selection of scoring content that scores the user's karaoke singing as karaoke content during the song selection operation.

[Karaoke unit]
The karaoke main unit 2 includes a control unit 10, a storage unit 11, and a communication unit 12. The control unit 10 includes a CPU (Central Processing Unit) and the like, and controls the karaoke device 1. The storage unit 11 includes storage media such as a ROM (Read Only Memory), a RAM (Random Access Memory), and a HDD (Hard Disc Drive). The communication unit 12 is an interface that communicates via a predetermined network (not shown), and is connected to the server device 101 and the mobile terminal 102 so as to be able to communicate with each other.

The storage unit 11 stores programs and data for controlling each part and function of the karaoke device 1. For example, the storage unit 11 stores basic information such as the song ID, song title, singer name, and genre for each song that the karaoke device 1 can play. The storage unit 11 stores various data related to karaoke performance, such as song data, for each song ID. The song data includes accompaniment data that is the basis for the accompaniment sounds of the karaoke song, reference data that is the scoring standard for singing, and lyric data that is the basis for the lyric captions displayed on the display device 3.

The storage unit 11 also stores programs and data for executing each karaoke content, and thus the karaoke device 1 is equipped with each karaoke content. Furthermore, the storage unit 11 stores a song distribution year table (see FIG. 2) and a content start year table (see FIG. 3) that the communication unit 12 receives from the server device 101. Note that instead of the song distribution year table, the storage unit 11 may store the distribution year together with basic information about each song.

The storage unit 11 stores user identification information (user ID) for each user of the karaoke device 1. The storage unit 11 stores the song IDs of the songs sung by each user together with the user ID as the singing history of each user for each karaoke singing (see FIG. 4). The singing history includes the content ID and year of use of the karaoke content used by the user when singing karaoke, and if the karaoke content used is scoring content that scores the user's karaoke singing, the scoring result (score) is also included.

The control unit 10 controls each unit and each function of the karaoke device 1 by executing calculations based on the programs and data stored in the memory unit 11. For example, the control unit 10 of this embodiment operates as a login processing unit 15, an acquisition unit 16, a first identification unit 17, a second identification unit 18, a recommendation unit 19, and a presentation unit 20 by executing the programs stored in the memory unit 11.

The login processing unit 15 receives a user ID from the remote control device 6 in response to a login operation of the remote control device 6 by the user, and stores the user ID in the storage unit 11 to perform login processing for the user corresponding to the user ID. The login processing unit 15 may allow multiple users who use the karaoke device 1 at the same time to each log in, that is, may accept simultaneous logins from multiple users. Note that the karaoke main unit 2 itself may have a function for inputting a user ID.

When a user selects (reserves) a song to be sung karaoke, the acquisition unit 16 acquires the delivery year in which the karaoke performance data of the song was delivered from the server device 101 to the karaoke device 1. For example, the acquisition unit 16 refers to a song delivery year table stored in the storage unit 11 to acquire the delivery year of the karaoke performance data corresponding to the song ID of the reserved song.

When the acquisition unit 16 acquires the distribution year of the karaoke performance data of the song, the first identification unit 17 identifies, as a first candidate, from among the multiple karaoke contents installed in the karaoke device 1, the karaoke content that was available on the karaoke device 1 in this distribution year. For example, the first identification unit 17 refers to a content start year table stored in the memory unit 11 and identifies, as a first candidate, karaoke content that was in operation in the same decade as the acquired distribution year. Specifically, the first identification unit 17 may identify, as a first candidate, karaoke content whose start year is before the distribution year.

The second identification unit 18 identifies, for a song selected (reserved) by the user to sing karaoke, the karaoke content used when the same song was previously sung karaoke, as a second candidate from among multiple karaoke contents installed in the karaoke device 1. For example, the second identification unit 18 refers to the singing history stored in the memory unit, and, based on a content ID included in the singing history that has the same song ID as the reserved song, identifies the karaoke content corresponding to this content ID as the second candidate.

The recommendation unit 19 recommends to the user at least the first candidate karaoke content identified by the first identification unit 17. Preferably, the recommendation unit 19 recommends to the user karaoke content based on the first candidate identified by the first identification unit 17 and the second candidate identified by the second identification unit 18. In this case, for example, the recommendation unit 19 may recommend to the user karaoke content that is common to the first and second candidates.

In addition, if there is no karaoke content common to the first and second candidates, the recommendation unit 19 may recommend the karaoke content of the first candidate to the user.

In this embodiment, an example has been described in which the second identification unit 18 performs the identification process of the second candidate and the recommendation unit 19 recommends karaoke content based on the first and second candidates, but the present invention is not limited to this example. For example, in other embodiments, the recommendation unit 19 may recommend karaoke content based only on the first candidate without performing the identification process by the second identification unit 18.

The presentation unit 20 presents the recommended karaoke content to the user by outputting information related to the karaoke content recommended by the recommendation unit 19 to the display device 3, the remote control device 6, and/or the mobile terminal 102 for display. For example, the presentation unit 20 presents the karaoke content when a song is reserved, when a karaoke performance of the song starts, etc.

[Karaoke device performance operation]
Next, a basic performance operation of the karaoke device 1 when a user sings karaoke will be described.

First, when a user operates the remote control device 6 to input a user ID, the login processing unit 15 in the karaoke main unit 2 receives the user ID from the remote control device 6 and performs login processing for that user.

When a user operates the remote control device 6 to reserve a song, the karaoke main unit 2 receives reserved song information including a song ID and a user ID from the remote control device 6, and registers this reserved song information in the reservation management table of the storage unit 11. The karaoke main unit 2 (control unit 10) reads the reserved song information from the reservation management table in the order of registration, and reads the song data etc. corresponding to the song ID of this reserved song information from the storage unit 11.

The karaoke main unit 2 (control unit 10) starts the karaoke performance based on the music data, and in synchronization with the playback of the accompaniment data, displays lyrics captions and background video on the display unit 3 based on the lyrics data and background video data. The karaoke main unit 2 also mixes the accompaniment sound signal of the karaoke performance and the singing voice signal input from the microphone 5 at an appropriate ratio using a mixer, amplifies this mixed signal using an amplifier, and emits it from the speaker 4. In this way, in the karaoke device 1, when a singer sings along with the karaoke performance, the singing voice is emitted from the speaker 4 together with the accompaniment sound. Furthermore, when scoring content is executed as the karaoke content, the karaoke device 1 scores the singing voice based on the reference data. The karaoke device 1 stores the singing scoring results in the memory unit 11 in association with the user ID and the music ID.

In addition, when karaoke performance is started even for a short time or when karaoke performance is started for a predetermined period of time, the karaoke device 1 stores the song ID of the song that was performed karaoke together with the user ID in the storage unit 11 in order to save the song as a singing history. At this time, if karaoke content is being played, the karaoke device 1 stores the content ID, the year of use, the score for the scored content, etc. in the singing history.

[Recommended behavior for karaoke content]
Next, the operation of recommending karaoke content by the karaoke device 1 will be described with reference to Fig. 5. Fig. 5 is a flow chart showing the operation of recommending karaoke content.

First, in the performance operation of the karaoke device 1 described above, when the logged-in user U operates the remote control device 6 to reserve song a with song ID "yyyya", the acquisition unit 16 acquires the user ID "Uxxxx1" and song ID "yyyya" from the remote control device 6 (step S1).

Next, the acquisition unit 16 acquires the year of distribution of the karaoke performance data of song a with song ID "yyyya" based on the song distribution year table (step S2).

For example, the song distribution year table shown in FIG. 2 stores song a with song name "a", song ID "yyyya", and distribution year "2012", song b with song name "b", song ID "yyyyb", and distribution year "2014", song c with song name "c", song ID "yyyyc", and distribution year "2016", and song d with song name "d", song ID "yyyyd", and distribution year "2020". In this case, the acquisition unit 16 acquires the distribution year "2012" of song a.

Next, the first identification unit 17 refers to the content start year table and identifies as the first candidate karaoke content that was available in the same decade as the distribution year "2012" of the reserved song a (step S3).

For example, in the content start year table shown in FIG. 3, karaoke content C1 with content ID "C1" and start year "2008", karaoke content C2 with content ID "C2" and start year "2010", karaoke content C3 with content ID "C3" and start year "2012", karaoke content C4 with content ID "C4" and start year "2014", karaoke content C5 with content ID "C5" and start year "2016", karaoke content C6 with content ID "C6" and start year "2018", and karaoke content C7 with content ID "C7" and start year "2020" are stored. In this case, the first identification unit 17 identifies karaoke content C1, C2, and C3 that started operation before the distribution year "2012" of song a as first candidates.

The second identification unit 18 also refers to the singing history of the user U and identifies as a second candidate the karaoke content that the user U has previously used for the same song as the song a that he or she has reserved (step S4).

For example, in the singing history of user U shown in Figure 4, song IDs "yyyya" and "yyyyb" of songs previously sung karaoke for user ID "Uxxxx1" are stored. In this singing history, the usage history of karaoke content previously used for song a with song ID "yyyya" includes usage history H1 of content ID "C1", usage year "2012", and score "90" points, usage history H2 of content ID "C1", usage year "2012", and score "92" points, usage history H3 of content ID "C1", usage year "2012", and score "91" points, and usage history H4 of content ID "C1", usage year "2013", and score "94" points. The usage history H4 of the content ID "C3", the usage year "2014", and the score "93", the usage history H5 of the content ID "C3", the usage year "2014", and the score "89", the usage history H6 of the content ID "C3", the usage year "2014", and the score "87", the usage history H7 of the content ID "C4", the usage year "2015", and the score "-" (no score), and the usage history H8 of the content ID "C5", the usage year "2017", and the score "-" (no score) are stored. In addition, in this singing history, the usage history H9 of the content ID "C6", the usage year "2018", and the score "-" (no score) and the usage history H10 of the content ID "C7", the usage year "2020", and the score "-" (no score) are stored as the usage history of the karaoke content used in the past for the song b with the song ID "yyyyb". In this case, the second identification unit 18 identifies the karaoke contents C1, C3, C4, and C5 included in the singing history of the song a of the user U as second candidates. Note that, according to the singing history, it can be understood that the karaoke contents C1 and C3, which have scores stored therein, are scored contents, and the karaoke contents C4, C5, C6, and C7, which have no scores, are not scored contents.

Next, the recommendation unit 19 determines the karaoke content that is common to the first candidate karaoke contents C1, C2, and C3 and the second candidate karaoke contents C1, C3, C4, and C5 (step S5).

As in the above example, if there are karaoke contents C1 and C3 common to the first and second candidates (step S5: YES), the recommendation unit 19 recommends these karaoke contents C1 and C3 to the user U (step S6). On the other hand, if there is no karaoke content common to the first and second candidates (step S5: NO), the recommendation unit 19 recommends the karaoke contents C1, C2, and C3 of the first candidate to the user U (step S7).

The presentation unit 20 presents the karaoke content recommended by the recommendation unit 19 to the user U via the display device 3, the remote control device 6 and/or the mobile terminal 102 (step S8).

As described above, the karaoke device 1 according to an embodiment of the present invention includes an acquisition unit 16 that acquires the delivery year in which the karaoke performance data of the reserved song was delivered to the karaoke device 1, a first identification unit 17 that identifies karaoke content that was available on the karaoke device 1 in the delivery year acquired by the acquisition unit 16 as a first candidate, and a recommendation unit 19 that recommends karaoke content to the user based on the first candidate identified by the first identification unit 17.

As a result, the karaoke device 1 can recommend karaoke content, even if it is old and infrequently performed, according to the user's song reservation status. In particular, the karaoke device 1 recommends karaoke content that was available in the same era as the year the reserved song was released, so it can recommend karaoke content that is expected to interest the user. Therefore, the user can further enjoy the multiple karaoke contents of the karaoke device 1, and furthermore, can enjoy singing karaoke using the karaoke device 1.

The karaoke device 1 further includes a second identification unit 18 that identifies a second candidate for the karaoke content to be recommended based on a singing history that stores karaoke content used by the user when singing a song in association with the song, and the recommendation unit 19 recommends karaoke content to the user based on the first candidate identified by the first identification unit 17 and the second candidate identified by the second identification unit 18.

As a result, the karaoke device 1 recommends karaoke content taking into consideration not only the year the reserved song was released, but also the karaoke content the user has used in the past, so it can narrow down the karaoke content it recommends to those that are likely to interest the user.

[First Modification]
As a first variant of the karaoke device 1, when the second identification unit 18 identifies a second candidate based on the singing history, it may identify as the second candidate a karaoke content that has been used in the past for the same song as the reserved song and that has been used a predetermined number of times (e.g., three times) or more.

For example, in the singing history of user U shown in FIG. 4, the usage history of karaoke contents C1, C3, C4, and C5 used in the past for song a with song ID "yyyya" is stored. Here, the usage history of karaoke content C1 is four times, the usage history of karaoke content C3 is two times, the usage history of karaoke content C4 is one time, and the usage history of karaoke content C5 is one time. In this case, the second identification unit 18 identifies karaoke content C1, which has been used a predetermined number of times (e.g., three times) or more, as the second candidate.

When this first modified example is applied to the karaoke content recommendation operation described above, the recommendation unit 19 will recommend to the user U the karaoke content C1 that is common to the first candidate karaoke contents C1, C2, and C3 and the second candidate karaoke content C1.

As a result, the first variant of the karaoke device 1 recommends karaoke content that the user has used frequently in the past, making it possible to narrow down the karaoke content recommendations to those that are expected to be of greater interest to the user.

[Second Modification]
As a second modified example of the karaoke device 1, when a specific user sings karaoke of a specific song and executes the scoring content as the karaoke content recommended by the recommendation unit 19, the presentation unit 20 may present the scoring result to the specific user via the display device 3, the remote control device 6 and/or the mobile terminal 102. Furthermore, the presentation unit 20 may present a past scoring result and a current scoring result for the karaoke singing of a specific song by the specific user, which are obtained by using the same scoring content, in a manner that allows comparison.

In addition, when user U currently reserves and sings song a with song ID "yyyya" at karaoke, if user U performs karaoke content C1, which is a scoring content recommended by recommendation unit 19, and obtains a current scoring result of "95" points, presentation unit 20 presents user U with the current scoring result of "95" points.

For example, in the singing history of user U shown in FIG. 4, a usage history of four past usages of karaoke content C1 for song a with song ID "yyyya" is stored. Here, the usage history H1 of karaoke content C1 has a score of "90" points, the usage history H2 has a score of "92" points, the usage history H3 has a score of "91" points, and the usage history H4 has a score of "93" points. In this case, the presentation unit 20 displays a score result screen 30 showing the highest past score of usage history H4, "93" points, and the current score of "95" points, as past scoring results, on the display device 3, the remote control device 6, and/or the mobile terminal 102, and presents it to user U, as shown in FIG. 6.

In addition, the presentation unit 20 may present the top past scoring results (e.g., first to third place) to the user instead of the highest past score as the past scoring results.

As a result, in the second variant of karaoke device 1, the singing situation when the user used the scoring content in the past and the singing situation when the user currently uses the scoring content are simultaneously presented to the user, allowing the user to further enjoy singing karaoke and using karaoke content.

[Other embodiments]
In the above embodiment, the karaoke machine 1 stores the singing history in the storage unit 11, and during the karaoke content recommendation operation, the singing history is read from the storage unit 11 and used in the process of identifying the second candidate by the second identification unit 18. However, the present invention is not limited to this example. For example, in another embodiment, the karaoke machine 1 may transmit the singing history to the server device 101 to store it in the server device 101, and during the karaoke content recommendation operation, the singing history may be received from the server device 101 and used in the process of identifying the second candidate by the second identification unit 18.

The present invention may be modified as appropriate within the scope of the claims and the entire specification without violating the spirit or concept of the invention, and karaoke devices incorporating such modifications are also included in the technical concept of the present invention.
