  The music distribution unit 26 transmits the music data of the music selected by the music selection unit 25 to the terminal 1.

FIG. 7 is a sequence diagram illustrating a flow of processing in which the distribution system 2 according to the embodiment selects music.
In the sequence diagram of FIG. 7, the state of the terminal 1 at the start of the process is that the terminal 1 is playing a music piece transmitted from the distribution system 2, and a menu screen as shown in FIG. Is displayed.

First, the user selects from the menu screen displayed on the display unit 15 of the terminal 1 a menu that displays a screen for inputting preference information for the music being played. Specifically, the user presses the preference information input button 153 in the example of FIG.
The input unit 13 receives an input of pressing the preference information input button 153 (step S101). The input unit 13 notifies the input control unit 14 that the preference information input button 153 has been pressed.

The input control unit 14 instructs the display unit 15 to display a preference information input screen. The display unit 15 displays a preference information input screen (step S102).
The user inputs preference information for the music being played from the preference information input screen. For example, on the preference information input screen in the example of FIG. 3, the user inputs a trajectory that passes through a favorite genre.
The input unit 13 receives input of preference information (step S103). The input unit 13 outputs the input preference information to the preference information input analysis unit 16.

The preference information input analysis unit 16 acquires information necessary for the distribution system 2 to select music from the input preference information (step S104). For example, when the trajectory of the example of FIG. 4 is input to the preference information input screen of FIG. 3, the preference information input analysis unit 16 corresponds to the genre information corresponding to the area in which the trajectory is input and each genre. The order in which the trajectory is input to the area to be processed and the length of the trajectory input to the area corresponding to each genre are acquired.
The preference information input analysis unit 16 outputs the acquired information (hereinafter referred to as “acquired information”) to the communication unit 11 and transmits it to the distribution system 2 (step S105).

The distribution system 2 receives the acquisition information transmitted from the terminal 1 (step S106).
The related music extraction unit 23 acquires the feature amount and metadata of the music being played on the terminal 1 from the music table 2211.
For example, in the example of FIG. 5, when the title of the music being played is “title 1”, the related music extraction unit 23 refers to the music table 2211 and selects a music record having “title 1” as the title value. To do. The related music extraction unit 23 acquires the feature value and the genre value of the selected music record. As a result, a feature value “10”, a genre value “jazz, rock”, and artist name values “artist 1, artist 2” are acquired.

The related music extraction unit 23 extracts a predetermined number of music related to the music being reproduced from the music stored in the music DB 221 based on the acquired feature value and metadata (step S107).
For example, in the example of FIG. 5, when the music being played is “title 1”, the related music extraction unit 23 acquires the artist name value “artist 1, artist 2” and the genre value “jazz, rock”. ”And the feature value“ 10 ”, the related music is extracted. The music may be extracted based on an arbitrary standard using the feature amount and metadata of the music being played.

For example, in the example of FIG. 5, first, a music piece having a feature value approximate to the feature value “10” of the music being played is extracted. As a result, music pieces having title values of “title 2” to “title 9” are extracted.
Next, music having a genre value approximate to the genre value “jazz, rock” to which the music being played belongs is extracted. As a result, music having title values “title 2” to “title 8” is extracted from the music extracted based on the feature value.
Next, the music having the artist name value similar to the artist name values “artist 1 and artist 2” related to the music being reproduced is extracted. As a result, music having title values of “title 2” to “title 7” is extracted from the music extracted based on the value of the genre.

  The preference music extraction unit 24 acquires user preference information from the preference information table 2221. The favorite music extraction unit 24 extracts a predetermined number of music from the music extracted by the related music extraction unit 23 based on the acquired user preference information (step S108).

  For example, in the example of FIG. 7, when the user who operates the terminal 1 is “user 1”, the favorite music extraction unit 24 refers to the preference information table 2221 and has a user value “user 1”. Select an information record. The favorite music extraction unit 24 acquires the value of the genre of the selected preference information record. As a result, the genre value “jazz, country, rock, latin, classic” is acquired. The favorite music extraction unit 24 extracts a predetermined number of related music from the music extracted by the related music extraction unit 23 based on the acquired genre value. As a result, music pieces having title values “title 2” to “title 6” are extracted.

  The music selection unit 25 selects music to be distributed next to the music being reproduced from the music extracted by the favorite music extraction unit 24. The music selection unit 25 calculates a feature amount representing a feature of the user's preference from the extracted information received in step S106. The song selection unit 25 selects a predetermined number of songs that approximate the user's preference from the songs extracted by the favorite song extraction unit 24 based on the calculated feature value (step S109).

For example, let us consider a case where the input locus 154 shown in the example of FIG. 4 is input as preference information on the preference information input screen of the example of FIG. In the example of FIG. 4, the length of the trajectory input to the area corresponding to “jazz” is “10”, and the length of the trajectory input to the area corresponding to “classic” is “30”. To do.
In this case, “Jazz” and “Classic” are set in the parameter J representing the genre corresponding to the region where the locus is input. In the parameter O [J] representing the order in which the trajectory is input in the area corresponding to the genre J, “1” is set to O [Jazz] and “2” is set to O [Classic]. In the parameter S [J] representing the length of the trajectory input in the area corresponding to the genre J, “10” is set in S [Jazz], and “30” is set in S [Classic]. By applying J, O [J] and S [J] set in this way to (Equation 1), a feature amount T [J] representing the strength of the user's preference for each genre J is obtained. When the input locus 154 shown in the example of FIG. 4 is input, “10” is calculated as T [Jazz], and “15” is calculated as T [Classic]. That is, the distribution system 2 determines that the user likes “jazz” and “classic” at a strength ratio of 2: 3.

  The music selection unit 25 selects music whose proportion of each genre in the music tone of the music approximates the feature amount T [J] from the music extracted by the favorite music extraction unit 24. As a result, the music having the title value “title 2” is selected from the music extracted by the favorite music extraction unit 24.

  The music distribution unit 26 sets the music selected by the music selection unit 25 as the music to be played next to the music being played on the terminal 1. The music distribution unit 26 transmits the music data of the selected music to the terminal 1 (step S110).

The terminal 1 receives the music data of the music transmitted from the distribution system 2 (step S111).
The terminal 1 reproduces the music data of the received music (Step S112).

  The music distribution system according to the embodiment configured as described above provides an interface for inputting a plurality of pieces of user preference information for attributes of music. As a result, the user of the music distribution system can more easily input a variety of preference information.

<Modification>

For example, the preference information record may include a feature amount of music that the user likes. In that case, the favorite music extraction unit 24 performs a matching process between the feature amount of the music that the user likes and the feature amount of the music extracted by the related music extraction unit 23, so that the music close to the user's preference. May be selected.
The preference information input screen of the embodiment shown in FIG. 3 is a screen that generates a visual effect following the user's input in order to make it easier for the user to grasp the information input by the user. It may be configured as.
FIG. 8 is a diagram illustrating a specific example of a preference information input screen according to a modification.
