Description

[Technical field]

[0001] The present invention relates to a server device. [Background technology]

[0002] During operation of a karaoke system, the use of an artist's appearance video or song may be suspended due to circumstances such as scandal involving the artist who released the song (original artist) or changes in copyright management of the song. For example, a technology has been disclosed in which, in response to scandal information about an artist provided to a server device from an external information providing server, the server device prohibits the karaoke device from displaying the appearance video of that artist (see, for example, Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Patent Publication No. 2021-124516 Summary of the Invention [Problem to be solved by the invention]

[0004] However, if the song whose use is to be suspended is registered in the user's favorites list, a situation may occur in which the song that cannot be played as karaoke remains in the user's favorites list.

[0005] To provide a server device which, when the use of a song registered in a favorites list is stopped, can change the stopped song in the favorites list to another song that can be substituted, thereby improving convenience for a user. [Means for solving the problem]

[0006] The main invention for achieving the above object is a server device communicatively connected to a karaoke machine, comprising: a first memory unit which stores attribute information including a song name and an artist name for each song in correspondence with song identification information; a second memory unit which stores a favorite list in which song identification information of favorite songs for each user is registered; an input unit which accepts input of usage suspension information for specifying a stopped song whose use by the karaoke machine is to be suspended; and a registration unit which, when the song identification information of the stopped song is registered in the favorite list, registers in the favorite list, instead of the song identification information of the stopped song, another song identification information having at least some attribute information that is the same as the song identification information of the stopped song. Effect of the Invention

[0007] According to the present invention, it is determined that another song having at least some of the same attribute information as the stopped song can be substituted for the stopped song, and the other song is registered in the favorites list in place of the stopped song registered in the favorites list. Therefore, even if a song in the favorites list is designated as the stopped song, the occurrence of a song that cannot be karaoke being left in the favorites list can be minimized. The stopped song in the favorites list can be automatically changed to another song that can be substituted, improving user convenience. [Brief description of the drawings]

[Figure 4] FIG. 11 is a flowchart illustrating an example of a processing operation of a server device according to the second embodiment. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0009] First Embodiment A karaoke system according to a first embodiment will be described with reference to Fig. 1 and Fig. 2. Fig. 1 is a configuration diagram of the karaoke system according to the first embodiment. Fig. 2 is a functional block diagram of a server device according to the first embodiment. Note that, for the sake of convenience, the functional block diagram of Fig. 2 shows functional blocks for realizing specific processing, but it is assumed that the server device is provided with the configuration that it normally has.

[0010] As shown in Fig. 1, the karaoke system 1 includes a server device 20 that is managed by a karaoke business operator and installed in a data center or the like, and karaoke devices 10 that are installed in karaoke stores 5 or the like. The server device 20 and the karaoke devices 10 are communicatively connected via a network 8. The server device 20 manages various information about songs and favorite lists in which each user's favorite songs are registered. When a user logs in to the karaoke device 10, the server device 20 applies the user's favorite list to each karaoke device 10.

[0011] The karaoke device 10 is connected to a monitor 11, a speaker 12, a microphone 13, and a remote control device 14. The monitor 11 displays lyrics captions together with a background image based on a video signal or the like from the karaoke device 10. The microphone 13 converts a singing voice into a singing voice signal and inputs it to the karaoke device 10. The speaker 12 emits the singing voice together with the performance sound based on the performance sound signal from the karaoke device 10 and the singing voice signal from the microphone 13. The remote control device 14 accepts various operations by the user for the karaoke device 10, such as reserving songs.

[0012] When the karaoke performance is started by the karaoke device 10, lyrics captions and background images are displayed on the monitor 11 in sync with the karaoke performance. In the karaoke device 10, the karaoke performance sound signal and the singing voice signal input from the microphone 13 are mixed by the mixer, and this mixed signal is amplified by the amplifier and output from the speaker 12. In this way, when the user sings along with the karaoke performance, the singing voice is output from the speaker 12 together with the performance sound. In addition, the karaoke device 10 scores the user's singing ability and the score result is displayed on the monitor 11.

[0013] In such a karaoke system 1, the karaoke operator may suspend the use of some songs on the karaoke device 10 due to circumstances such as a scandal involving an artist or changes in copyright management. In this case, if the karaoke operator suspends the use of songs registered in a user's favorites list, the favorites list will remain filled with songs that cannot be played as karaoke on the karaoke device 10. For this reason, the server device 20 takes into consideration circumstances such as a scandal involving an artist and automatically changes the suspended songs in the favorites list to other songs that can be substituted, thereby improving convenience for users.

[0014] As shown in Fig. 2, the server device 20 includes a first storage unit 21, a second storage unit 22, an input unit 23, and a registration unit 24. The first storage unit 21 stores a song database in which attribute information is associated with a song ID (song identification information) for each song. The song ID is information for identifying karaoke performance data. The attribute information for each song includes the song name, artist name, and version information. Examples of version information include an original studio version, a live version including a video of the artist performing, and a cover version covered by another artist.

[0015] The second storage unit 22 stores a favorite list in which the song IDs of favorite songs are registered for each user. For example, song names and song IDs are registered in the favorite list. By registering songs in the favorite list, it is possible to create a unique song list for each user. The input unit 23 accepts input of usage suspension information for designating songs to be suspended from use by the karaoke device 10. The input unit 23 is configured, for example, by an input screen displayed on the management terminal. Song IDs, artist names, and song names can be input into the input screen as usage suspension information.

[0016] When the song ID of the stopped song is registered in the favorites list, the registration unit 24 registers another song ID in the favorites list in place of the song ID of the stopped song. The other song ID is a song ID of another song that has at least a part of the attribute information the same as the song ID of the stopped song and can be substituted for the stopped song. For example, the favorites list registers the song ID of a cover song by another artist associated with the same song name as the stopped song. Also, for example, the favorites list registers the song ID of another song by the same artist associated with the same artist name as the stopped song.

[0017] More specifically, when the karaoke business operator inputs the song ID ****X2 of the stopped song as the usage suspension information to the server device 20, the karaoke performance data associated with the song ID ****X2 cannot be played on the karaoke device 10. The registration unit 24 of the server device 20 refers to the song database to identify the attribute information associated with the song ID ****X2 of the stopped song. For example, as shown in Table 1, the song title X, artist name A, and live version are identified as the attribute information associated with the song ID ****X2 of the stopped song. [Table 1]

[0018] One song name is associated with a song ID, but different song IDs are associated with songs of different versions even if the song name is the same. For this reason, the registration unit 24 refers to the song database to search for other song IDs associated with the same song name X as the song ID ****X2 of the stopped song. For example, as shown in Table 2, song IDs ****X1 and ****X3 with the same song name X as the song ID ****X2 of the stopped song are extracted. Song ID ****X1 is the studio version of song name X, and song ID ****X3 is a cover version of song name X by artist B. [Table 2]

[0019] When the registration unit 24 extracts another song ID of the song title X, the other song ID is registered in the favorites list instead of the song ID of the stopped song. For example, before the song ID ****X2 of the stopped song is input as the usage suspension information, the song ID ****X2 of the live version of the song title X is registered in the first line of the favorites list as shown in Table 3. When the song ID ****X2 of the stopped song is input as the usage suspension information, the song ID ****X3 of the cover version of the song title X by artist B is registered in the favorites list instead of the song ID ****X2 of the live version of the song title X as shown in Table 4. [Table 3] [Table 4]

[0020] Note that song IDs ****X1 and ****X3 are extracted as other song IDs of song title X, but it is possible to change which of song IDs ****X1 and ****X3 is to be registered in the favorites list. For example, a priority may be set in advance for each version of song IDs ****X1 and ****X3, and the song ID with the higher priority may be registered in the favorites list. Also, a song ID randomly selected by the registration unit 24 from song IDs ****X1 and ****X3, a song ID with a large number of plays nationwide including other users, or a song ID with a large number of favorite registrations nationwide may be registered in the favorites list.

[0021] If there is no other song ID associated with the same song name as the song ID of the stopped song, the registration unit 24 searches for other song IDs associated with the same artist name as this song ID. Naturally, even songs by the same artist are associated with different song IDs for each song name. For example, as shown in Table 5, song IDs ****V1, ****W1, ****Y1, and ****Z1 with the same artist name A as song ID ****X2 input as the usage suspension information are extracted. Song IDs ****V1, ****W1, ****Y1, and ****Z1 are associated with song names V, W, Y, and Z, respectively. [Table 5]

[0022] When the registration unit 24 extracts another song ID of artist A, the other song ID is registered in the favorites list instead of the song ID of the stopped song. For example, before song ID ****X2 of the stopped song is input as the usage suspension information, song ID ****X2 of song title X of artist A is registered in the first line of the favorites list as shown in Table 6. When song ID ****X2 of the stopped song is input as the usage suspension information, song ID ****V1 of song title V of the same artist A is registered in the favorites list instead of song ID ****X2 of song title X of artist A, as shown in Table 7. [Table 6] [Table 7]

[0023] Although song IDs ****V1, ****W1, ****Y1, and ****Z1 are extracted as other song IDs of artist A, it is possible to change which of song IDs ****V1, ****W1, ****Y1, and ****Z1 is to be registered in the favorites list. For example, a song ID with a newer release date and time may be registered in the favorites list. Also, a song ID randomly selected by the registration unit 24 from among song IDs ****V1, ****W1, ****Y1, and ****Z1, a song ID with a large number of plays nationwide including other users, or a song ID with a large number of favorite registrations nationwide may be registered in the favorites list.

[0024] If there is no other song ID associated with the same song name as the song ID of the stopped song, and there is no other song ID associated with the same artist name as the song ID of the stopped song, the registration unit 24 does not change the favorites list. In this case, the registration unit 24 may delete the song ID of the stopped song from the favorites list. Note that when use is suspended due to artist circumstances, song IDs of multiple songs corresponding to the artist may be input as usage suspension information, and when use is suspended due to song circumstances, multiple song IDs corresponding to the songs may be input as usage suspension information. In such cases, the registration unit 24 does not register the song ID input as usage suspension information in the favorites list.

[0025] The processing of each part of the server device 20 may be realized by software using a processor, or may be realized by a logic circuit (hardware) formed in an integrated circuit or the like. When a processor is used, the processor reads out and executes a program stored in the memory to perform various processes. For example, a CPU (Central Processing Unit) is used as the processor. The memory is composed of one or more storage media such as a ROM (Read Only Memory) and a RAM (Random Access Memory) depending on the application.

[0026] The processing operation of the server device of the first embodiment will be described with reference to Fig. 3. Fig. 3 is a flow diagram showing an example of the processing operation of the server device of the first embodiment. Note that the symbols in Fig. 2 will be used as appropriate for the description. Also, the following flow is merely an example and can be modified as appropriate.

[0027] 3, when the song ID of the stopped song is input to the karaoke company as the usage suspension information (Yes in step S01), the registration unit 24 refers to the song database to identify the song name and artist name associated with the song ID of the stopped song (step S02). Next, the registration unit 24 refers to the song database to search for other song IDs associated with the same song name as the song ID of the stopped song (step S03). In this case, the song name identified in the process of step S02 is set as a keyword, and other song IDs associated with this song name are searched for in the song database.

[0028] If there is another song ID associated with the same song name as the song ID of the stopped song (Yes in step S03), the registration unit 24 registers the other song ID in the favorites list instead of the song ID of the stopped song (step S04). As a result, the song ID of the other song, which has the same song name as the song ID of the stopped song but a different version, is registered in the favorites list by the registration unit 24. For example, instead of the song ID of a live version of the stopped song, the song ID of a cover version of the stopped song by another artist is registered in the favorites list.

[0029] On the other hand, if there is no other song ID associated with the same song name as the song ID of the stopped song (No in step S03), the registration unit 24 refers to the song database to search for other song IDs associated with the same artist name as the song ID of the stopped song (step S05). In this case, the artist name identified in the process of step S02 is set as a keyword, and other song IDs associated with this artist name are searched for in the song database.

[0030] If there is another song ID associated with the same artist name as the song ID of the stopped song (Yes in step S05), the registration unit 24 registers the other song ID in the favorites list instead of the song ID of the stopped song (step S06). As a result, even if the artist name is the same as that of the stopped song, a song ID with a different song name from the stopped song is registered in the favorites list by the registration unit 24. If there is no other song ID associated with the same artist name as the song ID of the stopped song (No in step S05), the processing of the server device 20 ends without changing the favorites list.

[0031] As described above, according to the first embodiment, it is determined that another song associated with the same song name or artist name as the stopped song can be substituted for the stopped song, and the other song is registered in the favorites list in place of the stopped song registered in the favorites list. Therefore, even if a song in the favorites list is designated as a stopped song, it is possible to minimize the occurrence of a song that cannot be karaoke remaining in the favorites list. The stopped song in the favorites list can be automatically changed to another song that can be substituted, thereby improving user convenience.

[0032] <Second embodiment> Next, a server device of the second embodiment will be described. The server device of the second embodiment differs from the server device of the first embodiment in the suspension information input to the input unit and the registration process of the registration unit. Therefore, for the second embodiment, the description of the same configuration as the first embodiment will be omitted using FIG. 2.

[0033] As shown in Fig. 2, the karaoke business operator inputs the artist name, song title, or song ID as the usage suspension information into the input unit 23 of the server device 20. For example, if an artist is involved in a scandal, the artist name is input as the usage suspension information. Also, if a song can no longer be used regardless of its version due to a change in copyright management or the like, the song title is input as the usage suspension information. Furthermore, if a live performance video or the like is distributed for a limited period of time, the song ID is input as the usage suspension information when the usage contract expires.

[0034] When the suspension information is an artist name, the registration unit 24 registers in the favorites list a song ID of another artist associated with the same song name as the song ID, instead of the song ID associated with the artist name.When the suspension information is a song name, the registration unit 24 registers in the favorites list a song ID of another song associated with the same artist name as the song ID, instead of the song ID associated with the song name.When the suspension information is a song ID, the registration unit 24 registers in the favorites list a song ID of another version associated with the same artist name or song name as the song ID, instead of the song ID.

[0035] More specifically, if artist A commits a scandal, the karaoke business operator inputs the artist name A as suspension information to the server device 20. In this case, the karaoke performance data of the song ID associated with the artist name A cannot be played on the karaoke device 10. The registration unit 24 of the server device 20 refers to the song database to identify the song ID and song name associated with the artist name A. For example, as shown in Table 8, song IDs ****V1, ****W1, ****X1, ****Y1, and ****Z1 of song names V, W, X, Y, and Z are identified. [Table 8]

[0036] The registration unit 24 refers to the song database to search for song IDs of other artists associated with the same song names as the song IDs ****V1, ****W1, ****X1, ****Y1, and ****Z1 of artist A. For example, as shown in Table 9, song ID ****X3 with song name X that is the same as song ID ****X1, song ID ****Y3 with song name Y that is the same as song ID ****Y1, and song ID ****Z3 with song name Z that is the same as song ID ****Z1 are extracted. Song IDs ****X3, ****Y3, and ****Z3 are cover versions of song names X, Y, and Z by artists B, E, and F, respectively. [Table 9]

[0037] When a song ID of another artist with song title X is searched for, the registration unit 24 registers the song ID of the other artist in the favorites list instead of the song ID of artist A. For example, before the artist name A is input as the suspension information, song ID ****X1 of the studio version of song title X is registered in the first line of the favorites list, as shown in Table 10. When the artist name A is input as the suspension information, song ID ****X3 of the cover version of song title X by artist B is registered in the favorites list, instead of song ID ****X1 of the studio version of song title X by artist A, as shown in Table 11. [Table 10] [Table 11]

[0038] Furthermore, when song X becomes unavailable regardless of the version due to a change in copyright management or the like, the karaoke business operator inputs song title X as usage suspension information to the server device 20. In this case, the karaoke performance data of the song ID associated with song title X cannot be played on the karaoke device 10. The registration unit 24 of the server device 20 refers to the song database to identify the song ID and artist name associated with song title X. For example, as shown in Table 12, song IDs ****X1, ****X2, and ****X3 of song title X are identified for each artist. [Table 12]

[0039] Since song title X is specified as the stopped song, the registration unit 24 refers to the song database to search for song IDs of other songs associated with the same artist name as song IDs ****X1, ****X2, ****X3 of song title X. For example, as shown in Table 13, song IDs ****W1, ****Y1, ****Z1 with the same artist name A as song IDs ****X1 and ****X2 are extracted. Song IDs ****W1, ****Y1, ****Z1 are associated with song names W, Y, Z, respectively. Although not described in detail here, a song ID with the same artist name B as song ID ****X3 is also searched for. [Table 13]

[0040] When the song ID of another song by artist A is searched for, the registration unit 24 registers the song ID of the other song in the favorites list instead of the song ID of song title X. For example, before song title X is input as suspension information, song ID ****X1 of song title X by artist A is registered in the first line of the favorites list, as shown in Table 14. When song title X is input as suspension information, song ID ****W1 of song title W by artist A is registered in the favorites list instead of song ID ****X1 of song title X by artist A, as shown in Table 15. [Table 14] [Table 15]

[0041] Furthermore, if the karaoke business operator inputs song ID****X2 to the server device 20 as usage suspension information due to reasons such as expiration of the usage contract, the karaoke performance data associated with song ID****X2 cannot be played on the karaoke device 10. The registration unit 24 of the server device 20 refers to the song database to identify the song name and version information associated with song ID****X2. For example, as shown in Table 16, the song name X and live version associated with song ID****X2 of the suspended song are identified. [Table 16]

[0042] Since the live version of song title X is specified as the stopped song, the registration unit 24 refers to the song database and searches for song IDs of different versions associated with the same song title X as song ID ****X2 of the stopped song. For example, as shown in Table 17, song IDs ****X1 and ****X3 of different versions of the same song title X as song ID ****X2 of the stopped song are extracted. Song ID ****X1 is the studio version of song title X, and song ID ****X3 is a cover version of song title X by artist B. [Table 17]

[0043] When a song ID of another version of song name X is searched for, the registration unit 24 registers the song ID of the other version in place of the song ID of the live version in the favorites list. For example, before the song ID ****X2 of the live version is input as the suspension information, the song ID ****X2 of the live version of song name X is registered in the first line of the favorites list as shown in Table 18. When the song ID ****X2 of the live version is input as the suspension information, the song ID ****X1 of the studio version of song name X is registered in the favorites list instead of the song ID ****X2 of the live version of song name X as shown in Table 19. [Table 18] [Table 19]

[0044] The processing operation of the server device of the second embodiment will be described with reference to Fig. 4. Fig. 4 is a flow diagram showing an example of the processing operation of the server device of the second embodiment. Note that the symbols in Fig. 2 will be used as appropriate for the description. Also, the following flow is merely an example and can be modified as appropriate.

[0045] As shown in Fig. 4, when the artist name of the stopped song is input to the karaoke company as the usage suspension information (artist name in step S11), the registration unit 24 refers to the song database to identify the song ID and song name associated with the artist name (step S12). Next, the registration unit 24 refers to the song database to search for a song ID of another artist associated with the same song name as the song ID of the artist of the stopped song (step S13). In this case, the song name identified in the process of step S12 is set as a keyword, and the song ID of another artist associated with this song name is searched for in the song database.

[0046] If a song ID of another artist exists for the same song name (Yes in step S13), the registration unit 24 registers the song ID of the other artist in the favorites list instead of the song ID of the artist of the suspended song (step S14). This allows a cover song by another artist to be registered in the favorites list even if the use of the song is suspended due to a scandal committed by the artist. If a song ID of another artist does not exist for the same song name (No in step S13), the processing of the server device 20 ends without changing the favorites list.

[0047] When the song name of the stopped song is input to the karaoke company as the usage suspension information (song name in step S11), the registration unit 24 refers to the song database to identify the song ID and artist name associated with the song name (step S15). Next, the registration unit 24 refers to the song database to search for the song ID of another song associated with the same artist name as the song ID of the stopped song (step S16). In this case, the artist name identified in the process of step S15 is set as a keyword, and the song ID of another song associated with this artist name is searched for in the song database.

[0048] If a song ID of another song by the same artist exists (Yes in step S16), the registration unit 24 registers the song ID of the other song by the same artist in the favorites list instead of the song ID of the stopped song (step S17). This allows the other song by the same artist to be registered in the favorites list even if use of the song is stopped due to a change in copyright management, etc. If a song ID of another song by the same artist does not exist (No in step S16), the processing of the server device 20 ends without changing the favorites list.

[0049] When the song ID of the stopped song is input to the karaoke company as the usage suspension information (song ID in step S11), the registration unit 24 refers to the song database to identify the song name and version information associated with the song ID (step S18). Next, the registration unit 24 refers to the song database to search for a song ID of a different version associated with the same song name as the song ID of the stopped song (step S19). In this case, the song name identified in the process of step S18 is set as a keyword, and the song ID of the different version associated with this song name is searched for in the song database.

[0050] If a song ID of a different version for the same song name exists (Yes in step S19), the registration unit 24 registers the song ID of the different version in the favorites list instead of the song ID of the stopped song (step S20). As a result, even if the use of the song is stopped due to the expiration of the usage contract, the different version of the same song is registered in the favorites list. If a song ID of a different version for the same song name does not exist (No in step S19), the processing of the server device 20 ends without changing the favorites list.

[0051] In the flowchart shown in Fig. 4, when a song ID is input to the karaoke company as the suspension information, a different version of the song ID associated with the same artist name as the song ID may be registered in the favorites list. In this case, in step S18, the song name, artist name, and version information associated with the song ID of the stopped song are specified. In step S19, a different version of the song ID associated with the same song name and artist name as the song ID of the stopped song is searched for.

[0052] As described above, according to the second embodiment, even if the use of a song is suspended due to a scandal involving an artist, due to changes in copyright management, or due to the expiration of a usage contract, the occurrence of songs that cannot be played karaoke remaining in the favorites list is minimized.

[0053] In the first embodiment, the attribute information includes the song name, artist name, and version information, but may also include the composer name, lyricist name, and the like.

[0054] In the above embodiment, a program may be installed in the server device to add the above-mentioned favorites list registration function to the server device. The program is stored in a storage medium. The storage medium is not particularly limited, and may be a non-transitory storage medium such as an optical disk, a magneto-optical disk, or a flash memory.

[0055] Although the present embodiment has been described, other embodiments may be obtained by combining the above-described embodiments and modifications in whole or in part.

[0056] In addition, the technology of the present invention is not limited to the above-mentioned embodiment, and may be variously changed, substituted, or modified within the scope of the gist of the technical idea. Furthermore, if the technical idea can be realized in a different way due to the progress of technology or a different technology derived therefrom, it may be implemented using that method. Therefore, the claims cover all embodiments that can be included in the scope of the technical idea. [Explanation of symbols]
