The operation unit 15 includes a user interface such as a keyboard, a mouse, or a touch panel, and receives operations from the business operator's personnel and outputs the received operation contents to the control unit 11.

[0033] The control unit 11 can be realized by the cooperation of hardware resources and software resources. A CPU, ROM, RAM, GPU, ASIC, FPGA, and other LSIs can be used as hardware resources. An operating system, middleware, application programs, and other programs can be used as software resources. The control unit 11 includes an introduction information registration unit 111, a store information registration unit 112, a content distribution management unit 113, a favorite information acquisition unit 114, a location information acquisition unit 115, and an introduction information distribution unit 116.

[0034] Advertiser server 40 of each company that acts as an advertiser stores advertising information for advertising the products or services of each company. Introduction information registration unit 111 acquires advertising information from advertiser server 40 of an advertiser who wishes to place an advertisement via network 5, and registers the advertising information in introduction information holding unit 122. The registered advertising information is advertising information for products or services related to artists who have given permission to distribute music content to music distribution service providers.

[0035] The advertising information is basically created as audio content advertising a product or service. For example, it may be audio content broadcast on a radio commercial, original audio content, or the audio portion of a video commercial broadcast on a TV, website, or video posting service.

[0036] The store information registration unit 112 acquires store information from the advertiser server 40 of the advertiser who wishes to place an advertisement via the network 5, and registers it in the store information holding unit 123. The registered store information is information about at least one store that provides the product or service related to the advertisement information. The provision of a product or service includes sale and free provision. The following explanation uses sale as an example. Note that a store is an example of a place where a product or service is provided. Places where a product or service is provided also include facilities and event venues. The store information registered in the store information holding unit 123 includes address information of each store.

[0037] The introduction information registration unit 111 obtains introduction information (hereinafter referred to as artist introduction information) about the artist's business projects or favorite products or services from the artist terminal device 50 of the artist who has granted permission to distribute music content to a music distribution service provider via the network 5, and registers the information in the introduction information storage unit 122.

[0038] The artist terminal device 50 may be a terminal device (PC, smartphone, etc.) of the artist, or a terminal device of the production company or talent agency to which the artist belongs. The artist introduction information may be audio content posted on SNS or blogs, the audio portion of video content posted on SNS or blogs, or original audio content. When the artist introduction information is stored in a cloud server used by the artist or the production company or talent agency to which the artist belongs, the artist introduction information stored in the cloud server is transmitted to the information distribution system 10 by operating the artist terminal device 50.

[0039] The introduction information registration unit 111 acquires store information from the artist terminal device 50 via the network 5 and registers it in the store information holding unit 123. The registered store information is information about at least one store that sells the product or service related to the artist introduction information, and includes address information of each store. The store information may be input from the artist terminal device 50 by the artist himself / herself, or may be input from the artist terminal device 50 by a staff member (e.g., a manager) of the production company or talent agency to which the artist belongs.

[0040] The products related to the artist introduction information may include goods of the artist himself, or may include the menu of the artist's favorite restaurant.

[0041] When content distribution management unit 113 receives a request to play music content via network 5 from mobile terminal device 20 owned by a user who uses the music distribution service, it streams the music content requested to be played to the requesting mobile terminal device 20. The music content (audio source data) may be stored in a music content storage unit (not shown) in storage unit 12, or the music content may be stored in a separate database server for storage.

[0042] The favorite information acquisition unit 114 receives favorite artist information via the network 5 from the mobile terminal device 20 owned by the user who uses the music distribution service.

[0043] The location information acquisition unit 115 receives location information of the mobile terminal device 20 in real time via the network 5 from the mobile terminal device 20 that is currently playing back a music content stream.

[0044] The introduction information distribution unit 116 determines whether or not the music content being streamed is music content of the user's favorite artist acquired by the favorite information acquisition unit 114. The introduction information distribution unit 116 tracks the location information of the mobile terminal device 20 acquired by the location information acquisition unit 115 while the music content of the user's favorite artist is being streamed (while the content is being played on the mobile terminal device 20).

[0045] The introduction information distribution unit 116 determines whether the location of the mobile terminal device 20 while content is being played is within a specified distance from the location of the store, based on the location information of the mobile terminal device 20 while content is being played, the location information of a store selling products or services related to a favorite artist, and map data around the location information read from the map data storage unit 121.

[0046] When the position of the mobile terminal device 20 is within a predetermined distance from the position of the store, the introduction information distribution unit 116 distributes advertising information of products or services related to the favorite artist or artist introduction information to the mobile terminal device 20. In this case, the introduction information distribution unit 116 may extract only stores that are within a predetermined distance from the position of the mobile terminal device 20 in the moving direction of the user who owns the mobile terminal device 20.

[0047] When a store within a predetermined distance from the location of the mobile terminal device 20 carries multiple products or services related to a favorite artist, the recommendation information distribution unit 116 may select one product or service based on predetermined conditions, or may prioritize the multiple products or services.

[0048] If an artist appears in multiple commercials or provides songs for multiple commercials, that artist will be associated with multiple products or services. Also, if the extracted store is a large shopping center, there is a high possibility that multiple products or services related to your favorite artist are sold.

[0049] If the extracted store sells multiple products or services related to the favorite artist, the recommendation information distribution unit 116 may select one product or service based on the season, weather, time of day, etc. For example, if it is a sunny summer afternoon and the products related to the favorite artist include soft drinks, the recommendation information distribution unit 116 distributes advertising information for the soft drinks related to the favorite artist to the mobile terminal device 20.

[0050] In the case where the extracted store sells a plurality of products or services related to a favorite artist and a plurality of pieces of advertisement information are distributed to the mobile terminal device 20, the introduction information distribution unit 116 may determine the order of distribution of the plurality of pieces of advertisement information based on the season, weather, and time period. For example, in the case where the favorite artist provides music for commercials for soft drinks and apparel, and it is a sunny summer afternoon, the introduction information distribution unit 116 distributes the advertisement information for the soft drinks related to the favorite artist and the advertisement information for the apparel to the mobile terminal device 20 in that order. Note that the advertisement information with a high priority may be distributed as a long version of the audio content, and the advertisement information with a low priority may be distributed as a short version of the audio content.

[0051] In addition, when the extracted store sells multiple products or services related to the favorite artist, the introduction information distribution unit 116 may narrow down the advertisement information to be distributed according to the user's attributes. For example, when the user is a man and the products related to the favorite artist include cosmetics for women, the introduction information distribution unit 116 does not distribute advertisement information for cosmetics for women to the mobile terminal device 20 of the user's account. In addition, when the user is a minor and the products related to the favorite artist include alcoholic beverages, the introduction information distribution unit 116 does not distribute advertisement information for alcoholic beverages to the mobile terminal device 20 of the user's account.

[0052] 2 is a flowchart showing a flow of a distribution process of advertisement information by the information distribution system 10 according to the embodiment. The introduction information registration unit 111 of the information distribution system 10 acquires advertisement information from the advertiser server 40, and registers it in the introduction information holding unit 122. The store information registration unit 112 acquires store information selling a product or service related to the advertisement information from the advertiser server 40, and registers it in the store information holding unit 123 (step S10).

[0053] The content playback management unit 211 of the mobile terminal device 20 identifies the user's favorite artist based on the number of times or the playback time of music content in a predetermined period (step S20). When the music distribution application installed in the mobile terminal device 20 is started, the favorite information transmission unit 212 transmits favorite artist information to the information distribution system 10 (step S21).

[0054] The content playback management unit 211 transmits a playback request for the musical piece content selected by the user to the mobile terminal device 20 (step S22). When the content delivery management unit 113 of the information delivery system 10 receives a playback request from the mobile terminal device 20, it starts streaming delivery of the musical piece content requested to be played to the requesting mobile terminal device 20 (step S11).

[0055] Content playback management unit 211 of mobile terminal device 20 plays music content streamed from information delivery system 10, and outputs the played audio signal to audio device 30. Location information transmission unit 213 transmits location information detected by GPS receiving unit 23 to information delivery system 10 during streaming playback of the music content (step S23).

[0056] The introduction information distribution unit 116 of the information distribution system 10 determines whether the artist of the music content being streamed is a favorite artist of the user who owns the mobile terminal device 20 to which the music content is being streamed (step S12). If the artist is the user's favorite artist (step S12: Yes), the introduction information distribution unit 116 identifies advertisement information and store information for products or services related to the favorite artist (step S13). The introduction information distribution unit 116 tracks the location information of the mobile terminal device 20 acquired by the location information acquisition unit 115.

[0057] The introduction information distribution unit 116 determines whether the location of the mobile terminal device 20 that is the streaming distribution destination is within a predetermined distance from the location of the identified store (step S14). If it is within the predetermined distance (step S14: Yes), the introduction information distribution unit 116 distributes advertising information for products or services related to the favorite artist to the mobile terminal device 20 that is the streaming distribution destination (step S15).

[0058] When advertising information is distributed from information distribution system 10, content playback management unit 211 of mobile terminal device 20 superimposes the advertising information on the music content, regardless of whether it is between songs or during the song being played. At that time, content playback management unit 211 lowers the volume of the music content or mutes it. Note that content playback management unit 211 may also temporarily suspend playback of the music content. In this embodiment, in order to prioritize broadcasting advertising information at a location close to the store, there is no need to wait until playback of the music content is completed.

[0059] The music distribution application installed in the mobile terminal device 20 may have a function of skipping advertising information superimposed during the playback of music content based on a user's operation. The music distribution application may also have a function of feeding back advertising information in which the user is not interested to the information distribution system 10 based on a user's operation. From the next time onwards, the introduction information distribution unit 116 of the information distribution system 10 will not distribute advertising information for which the user has given feedback that he or she is not interested to the mobile terminal device 20 of the user's account.

[0060] In step S12, if the artist of the music content being streamed is not a favorite artist of the user who owns the mobile terminal device 20 to which the streaming is being delivered (step S12: No), the processes of steps S13-S16 are skipped. In step S14, if the location of the mobile terminal device 20 to which the streaming is being delivered is not within a predetermined distance from the location of the identified store (step S14: No), the process of step S15 is skipped.

[0061] In addition, when there is no advertising information for a favorite artist, when the user does not approach a store selling a product or service related to the favorite artist for a predetermined time or more, or when the user is playing a song by an artist other than the favorite artist, the introduction information distribution unit 116 can distribute randomly selected advertising information to the mobile terminal device 20. In this case, the introduction information distribution unit 116 may randomly select from advertising information for a product or service sold at a store located closest to the user after considering the user's attributes, and distribute the selected advertising information to the mobile terminal device 20.

[0062] In the mobile terminal device 20, until the playback of the one piece of content is completed (step S25: No), the process transitions to step S23, and the location information transmitting unit 213 continues to transmit the location information to the information distribution system 10. In the information distribution system 10, until the playback of the one piece of content is completed (step S16: No), the process transitions to step S14, and the introduction information distributing unit 116 continues to compare the location of the mobile terminal device 20 with the location of the store.

[0063] In the mobile terminal device 20, when the playback of one piece of content has ended (step S25: Yes), if the user plays another piece of music content (step S26: Yes), the process transitions to step S22 and repeats the process from step S22 onwards. In the information distribution system 10, when the playback of one piece of content has ended (step S16: Yes), if the user plays another piece of music content (step S17: Yes), the process transitions to step S11 and repeats the process from step S11 onwards. If another piece of music content is not being played (step S26: No, step S17: No), the entire process ends.

[0064] 3 is a flowchart showing a subroutine of the advertisement information distribution process in step S15 of the flowchart in FIG. 2. When a store that sells a product or service related to a favorite artist sells multiple products or services related to the favorite artist (step S151: Yes), the introduction information distribution unit 116 selects advertisement information to be distributed based on the season, weather, and time period (step S152). The introduction information distribution unit 116 distributes the selected advertisement information to the mobile terminal device 20 that is the streaming distribution destination (step S153). When only one product or service related to the favorite artist is sold (step S151: No), the introduction information distribution unit 116 selects advertisement information for that product or service, and distributes the selected advertisement information to the mobile terminal device 20 that is the streaming distribution destination (step S153).

[0065] 4 is a schematic diagram showing a specific example of the advertisement information distribution process. Assume that convenience store P1 does not sell products related to user U1's favorite artist, and shopping center P2 sells products related to user U1's favorite artist. In this example, even if user U1 approaches convenience store P1 while walking along the road, advertisement information for products related to the favorite artist is not distributed to user U1. When user U1 approaches shopping center P2, advertisement information for products related to the favorite artist is distributed to user U1.

[0066] 5 is a flowchart showing a flow of a distribution process of artist introduction information by the information distribution system 10 according to the embodiment. The introduction information registration unit 111 of the information distribution system 10 acquires the artist introduction information from the artist terminal device 50, and registers it in the introduction information holding unit 122. The shop information registration unit 112 acquires store information selling the product or service related to the artist introduction information from the artist terminal device 50, and registers it in the shop information holding unit 123 (step S10a).

[0067] The content playback management unit 211 of the mobile terminal device 20 identifies the user's favorite artist based on the number of times or the playback time of music content in a predetermined period (step S20). When the music distribution application installed in the mobile terminal device 20 is started, the favorite information transmission unit 212 transmits favorite artist information to the information distribution system 10 (step S21).

[0068] The content playback management unit 211 transmits a playback request for the musical piece content selected by the user to the mobile terminal device 20 (step S22). When the content delivery management unit 113 of the information delivery system 10 receives a playback request from the mobile terminal device 20, it starts streaming delivery of the musical piece content requested to be played to the requesting mobile terminal device 20 (step S11).

[0069] Content playback management unit 211 of mobile terminal device 20 plays music content streamed from information delivery system 10, and outputs the played audio signal to audio device 30. Location information transmission unit 213 transmits location information detected by GPS receiving unit 23 to information delivery system 10 during streaming playback of the music content (step S23).

[0070] The introduction information distribution unit 116 of the information distribution system 10 determines whether the artist of the music content being streamed is a favorite artist of the user who owns the mobile terminal device 20 to which the content is to be distributed (step S12). If the artist is the user's favorite artist (step S12: Yes), the introduction information distribution unit 116 identifies the artist introduction information and store information of the favorite artist (step S13a). The introduction information distribution unit 116 tracks the location information of the mobile terminal device 20 acquired by the location information acquisition unit 115.

[0071] The introduction information distribution unit 116 determines whether the location of the mobile terminal device 20 that is the streaming distribution destination is within a predetermined distance from the location of the identified store (step S14). If it is within the predetermined distance (step S14: Yes), the introduction information distribution unit 116 distributes the artist introduction information of the favorite artist to the mobile terminal device 20 that is the streaming distribution destination (step S15a).

[0072] When the artist introduction information is distributed from the information distribution system 10, the content playback management unit 211 of the mobile terminal device 20 superimposes the artist introduction information on the music content, regardless of whether it is between songs or during the music content being played. At that time, the content playback management unit 211 lowers or mutes the volume of the music content. In this embodiment, in order to give priority to conveying the introduction information of a favorite artist to fans, the content playback management unit 211 does not wait until the end of the music content playback.
