Each unit (functional configuration) shown in FIG. 1 is realized by the above DJ application stored in the hard disk drive.

  The compatibility information input unit 110 corresponds to an “input unit” in claims, and inputs compatibility information indicating a degree of compatibility between music contents (hereinafter simply referred to as “music”). In the present embodiment, compatibility information is input by pressing the match button 30 in a state where music is loaded on two players (see the player display units 21, 31 and FIG. 3).

  The content information storage unit 130 stores content information related to each song. As shown in FIG. 2, as the content information, in addition to the title, album, artist, BPM, tonality, genre, etc. of the music, the above compatibility information is stored (corresponding to the “compatibility information storage unit” in the claims). . In the present embodiment, the compatibility information indicates a music having good compatibility. That is, as shown in the figure, when “Song B”, “Song C”, and “Song D” are registered for “Song A”, “Song B” and “Song C” are registered with respect to “Song A”. "," Song D "means that the music has good compatibility. Since the compatibility information indicates the compatibility between the two songs, “Song A” is registered as the compatibility information for “Song B”, “Song C”, and “Song D” (in FIG. Only “Song B” is shown). In addition, as the content information, artwork (such as an album jacket image), song evaluation, song length, song waveform, and the like may be stored. The content information storage unit 130 may be provided not in the display device 1 but in an external device (such as a server on the Internet or a USB device) that can communicate with the display device 1.

  The compatibility level display unit 140 displays the compatibility level of the music loaded on the two players. In the present embodiment, the degree of compatibility (binary of whether or not compatibility is good) is displayed by turning on / off the match button 30. Here, the lighting of the match button 30 means that the compatibility between the two songs is good, and the non-lighting of the match button 30 means that the compatibility between the two songs is not good.

  The recommendation display unit 150 displays music to be recommended to the user. In the present embodiment, one or more songs that are compatible with any of the music loaded in “Player 1”, the music loaded in “Player 2”, and the music selected in the music list are displayed ( (See recommendation display area 43, FIG. 3, etc.).

  The display control unit 160 performs display control of the compatibility level display unit 140 and the recommendation display unit 150. Specifically, the compatibility level is displayed on the compatibility level display unit 140 (match button 30) based on the compatibility information of the two songs loaded on the two players. In addition, when an arbitrary music is selected in the music list or loaded on the player, another music that is compatible with the arbitrary music is displayed on the recommendation display unit 150 based on the compatibility information of the arbitrary music. .

  The target content selection unit 180 selects the target music to be the comparison source music when displaying the compatible music on the recommendation display unit 150 (see the target music selection area 42, FIG. 3 and the like). Specifically, one of the music loaded in “Player 1”, the music loaded in “Player 2”, and the music selected in the music list is selected.

  When there are a plurality of other music pieces that are compatible with the target music selected by the target content selection section 180, the recommendation level calculation section 170 calculates a recommendation level for each of the other music pieces. Specifically, the degree of recommendation is calculated based on the closeness of the content information of the target music and the content related information of other music. For example, the recommendation degree is high for music with a close BPM, music with a close tonality, music with the same artist, and music with the same genre. When there are a plurality of other songs that are compatible with the target song, the display control unit 160 recommends the other songs according to the recommendation level calculated by the recommendation level calculation unit 170 (in descending order of recommendation level). They are listed on the display unit 150.

  The recommendation level calculation unit 170 may calculate the recommendation level by comprehensively determining each item included in the content information, or may calculate the recommendation level based on a specific item. Further, a specific item may be selectable by the user by an environment setting or the like.

  Next, a GUI displayed on the display of the display device 1 as one function of the DJ application will be described with reference to FIG. As shown in the figure, the GUI includes a player unit 11 and a browse unit 12.

  The player unit 11 includes a first player display unit 21 that displays the music loaded on the “player 1”, and a second player display unit 31 that displays the music loaded on the “player 2”. Each player display section 21, 31 displays player name display areas 22, 32 for displaying player names, controls such as play / pause buttons 23, 33, time display of the music being played, BPM, overall waveform, etc. Information display areas 24 and 34.

  Further, a match button 30 is arranged on the right side of each player display section 21, 31. The match button 30 is pressed (by the mouse) when the user plays the music of “Player 1” and “Player 2” (as a result of connecting and playing or simultaneously playing (mixing playback)) and determines that the compatibility is good. Click operation etc.). When the match button 30 is pressed, compatibility information is registered as the content information of both “player 1” and “player 2” music pieces.

  As shown in FIG. 3, when the match button 30 is pressed in a non-lighted state, the match button 30 is lit as shown in FIG. In other words, the lighting of the match button 30 means that the compatibility between the music of “Player 1” and “Player 2” is good. Also, when the music is loaded on each player, the match button 30 is turned on as shown in FIG. 4 in the case of a combination of music for which compatibility information is already registered. When the match button 30 is pressed in this state, as shown in FIG. 3, the match button 30 is turned off, and the compatibility information of both music pieces is deleted. In other words, if the user determines that the compatibility is poor as a result of playing the music of “Player 1” and “Player 2”, the compatibility information can be deleted.

  On the other hand, the browsing unit 12 includes a music list display area 41, a target music selection area 42, and a recommendation display area 43. The music list display area 41 displays content information (title, artist, album, and genre in the example in the figure) in units of rows and lists each content information in the column direction.

  The target music selection area 42 selects a music (hereinafter referred to as “recommendation target”) that is a target when displaying a compatible music in the recommendation display area 43. In the present embodiment, “player 1 (music loaded on player 1)”, “player 2 (music loaded on player 2)”, “music list (music list display area 41) is selected from the pull-down menu. "Music") can be selected. In the example of FIG. 3, “Player 1” is selected in the target music selection area 42, and music that is compatible with “Song A” loaded in “Player 1” is displayed in the recommendation display area 43. Is shown.

  The recommendation display area 43 displays a list of music that is compatible with the music selected in the target music selection area 42 as music to be recommended to the user. As described above, when there are multiple compatible music pieces, the music pieces are displayed in descending order of the degree of recommendation calculated by the recommendation degree calculation unit 170. In the example of FIG. 3, recommended songs (hereinafter referred to as “recommended songs”) are listed in the order of “Song A” and BPM (the BPM of “Song A” is assumed to be “120”). . As shown in FIG. 4, when “Song List” is selected in the target song selection area 42 and any song (see reference numeral 51) is selected in the song list display area 41, the recommendation display area 43 is displayed. , The recommended music ("Song A", "Song C", "Song D" in the example in the figure) that is compatible with the selected music ("Song B in the example in the figure)" is the selected music Are listed in order from the closest BPM (the BPM of “Song B” is assumed to be “125”).

  Next, the flow of the compatibility information update process will be described with reference to the flowchart of FIG. The flowchart corresponds to the screen transitions of FIGS. 3 and 4. When two music pieces (here, “Song A” and “Song E”) are loaded into “Player 1” and “Player 2” (S01, S02), the display device 1 (PC) reads “Song A”. It is determined whether or not compatibility information indicating that the compatibility of “Song E” is registered in the content information storage unit 130 (S03). If the compatibility information is not registered (S03: No), the compatibility information indicating that “Song A” and “Song E” have good compatibility is registered (S05: Yes) when the match button is pressed (S04: Yes). ). That is, “Song E” is registered as compatibility information of “Song A”, and “Song A” is registered as compatibility information of “Song E”.

  On the other hand, when the compatibility information is registered (S03: Yes), the compatibility information indicating that “Song A” and “Song E” are compatible is deleted when the match button is pressed (S06: Yes). (S07). That is, “Song E” is deleted from the compatibility information of “Song A”, and “Song A” is deleted from the compatibility information of “Song E”.

  Next, the flow of recommended song display processing will be described with reference to the flowchart of FIG. The flowchart corresponds to the screen of FIG. When “Song B” is selected as a recommendation target in the song list display area 41 by the user's operation (S11), the display device 1 (PC) selects a song having a good compatibility with “Song B” from the content information storage unit 130. (S12). That is, a music piece in which “Song B” is registered as compatibility information is searched. Here, when there is no music having good compatibility with “Song B” (S13: No), the process is ended without displaying the recommended music in the recommendation display area 43.

  On the other hand, if there is a song having good compatibility with “Song B” (S13: Yes), it is determined whether or not there are a plurality of songs having good compatibility (S14). When there are a plurality of music pieces having good compatibility (S14: Yes), the display order is determined according to the recommendation level calculated by the recommendation level calculation unit 170 (S15). Thereafter, in the determined display order, a plurality of recommended songs that are compatible with “Song B” are displayed in the recommendation display area 43 (S16). If there is not a plurality of music pieces having good compatibility (S14: No), one music piece having good compatibility with “Song B” is displayed in the recommendation display area 43 (S16).

  As described above, in the first embodiment, the compatibility information is registered based on the subjective judgment of the user, and the recommended music is displayed based on the compatibility information. As a result, even if the music feature amount is far from the music loaded on “Player 1” or “Player 2” or the music selected in the music list (recommended object), You can recommend songs that can be judged to be compatible.

  In addition, when there are multiple compatible songs for the recommendation target, the recommendation level is determined based on content-related information that is objective information, and the display order is determined according to the recommendation level. It is possible to grasp which musical piece has a high recommendation level subjectively and objectively from among the plurality of displayed recommended musical pieces.

  In addition, since the compatibility between the music loaded in “Player 1” and “Player 2” is displayed (compatibility display section 140), the user can grasp the compatibility at the time of loading. As a result of playing (testing) two music pieces, when it is determined that the compatibility is good, the match button 30 is pressed to light up. When it is determined that the compatibility is not good, the match button 30 is pressed to turn off. The compatibility information can be easily rewritten simply by pressing the match button 30 such as lighting.

In addition, the following modifications can be employed.
[Modification 1]
In the above embodiment, when there are a plurality of recommended songs, the recommendation degree is determined based on the content related information. However, in addition to the content related information or instead of the content related information, the playback history or registration history of the content The recommendation degree may be determined based on For example, a playback history (a piece of music played back and its number of times, etc.) is stored as part of the content information, and each recommended song (other content) is played when the recommendation target (arbitrary content) is determined. It is conceivable that the recommendation level is calculated based on the history (the recommendation level is increased as the number of connected and played music is larger). In addition, it is also possible to increase the recommendation level of recommended songs having a large number of playbacks, and to increase the recommendation level of songs whose registration time is late (recently registered songs). Also, in addition to the content playback history and registration history, increase the recommendation level for highly rated songs, and increase the recommendation level for songs that fall under the “favorite artist” or “favorite genre” set by the user in the environment settings, etc. , Etc. are also possible.

[Modification 2]
Moreover, in said embodiment, although the compatibility was represented by the binary of whether compatibility was good, you may represent it by the level of three or more steps. That is, the degree of compatibility between songs loaded on “player 1” and “player 2” may be set at three or more levels. In this case, the recommendation level may be calculated in consideration of the level of compatibility. In other words, the recommendation level may be set higher for the music having a higher compatibility level and preferentially displayed in the recommendation display area 43. Furthermore, the recommendation level may be calculated by comprehensively determining the level of compatibility with content-related information (including content reproduction history and registration history). For example, it is conceivable that the recommendation level is calculated by a predetermined calculation formula including a parameter that varies depending on the content-related information and a parameter indicating the level of compatibility.

[Modification 3]
In the above embodiment, the compatibility information is input by pressing the match button 30 while the music is loaded on the “player 1” and the “player 2”. However, the compatibility information is input by another method. You may do it. For example, by selecting a plurality of music pieces in the music list, the compatibility information of those music pieces may be registered.

[Modification 4]
Further, in the above embodiment, other content that is compatible with the selected or loaded arbitrary content is displayed in the recommendation display area 43, but conversely, other content that is incompatible with the arbitrary content (the degree of compatibility is (Low content) may be displayed. Also, both content with good compatibility and content with low compatibility may be displayed in different areas.

[Second Embodiment]
Next, a second embodiment of the present invention will be described with reference to FIG. In the first embodiment, the compatibility information is input by the compatibility information input unit 110. However, in the present embodiment, the compatibility information is acquired from the external device 300. Only differences from the first embodiment will be described below. In the present embodiment, the same components as those in the first embodiment are denoted by the same reference numerals, and detailed description thereof is omitted. Moreover, the modification applied about the component similar to 1st Embodiment is applied similarly about this embodiment.

Although the selection method is not particularly illustrated, it is conceivable to select a live house or club that owns the network-connected external device 300 and acquire compatibility information from these external devices 300.

  The compatibility information update unit 220 updates the compatibility information by the three-stage theory based on the compatibility information acquired by the compatibility information acquisition unit 120. For example, when the compatibility information indicates whether or not the compatibility is good, the compatibility information indicating that “Song A” and “Song B” are compatible is acquired from “External Device X”, and “External Device” When compatibility information indicating that “Song B” and “Song C” are compatible with each other is acquired from “Y”, it is assumed that “Song A” and “Song C” have good compatibility. Update information. That is, “Song C” is added to the compatibility information of “Song A”, and “Song A” is added to the compatibility information of “Song C”. In addition, for a combination of music pieces for which compatibility information has been acquired from a plurality of external devices 300, processing for updating the compatibility information (for example, increasing the level of compatibility) may be performed assuming that the compatibility is high.

  Note that the display processing by the compatibility display unit 140 and the recommendation display unit 150 is the same as that in the first embodiment, and thus the description thereof is omitted. Further, the recommendation level calculation unit 170 may acquire content information (including compatibility information) from the external device 300 and calculate the recommendation level based on the content information.

  As described above, according to the second embodiment, since the display device 1 is connected to the external device 300, compatibility information based on the subjectivity of others can be acquired. Further, since the external device 300 from which the compatibility information is acquired can be selected, for example, recommendation information of a favorite live house or favorite DJ can be known. Furthermore, since the compatibility information in the content information storage unit 130 is updated as needed based on the compatibility information acquired from the plurality of external devices 300, it is possible to display recommended music with higher reliability.

In addition, the following modifications can be employed.
[Modification 5]
In the above embodiment, the external device 300 that is the source of the compatibility information is selected from the one or more external devices 300. However, the external device 300 may not be selected. In this case, the compatibility information input unit 110 of the first embodiment may be added to the second embodiment, and the recommended music may be determined based on the compatibility information input by the compatibility information input unit 110. Further, the recommended music may be determined based on both the compatibility information input by the compatibility information input unit 110 and the compatibility information acquired from the external device 300.

[Modification 6]
Further, although not specifically illustrated, in the display device 1 (and the external device 300 having the same configuration as the display device 1), an external device including the content information storage unit 130 is further connected to the network NW of the display system SY in FIG. The compatibility information or recommended music may be displayed with reference to the content information storage unit 130.
