Music data related to each event can be selected, and as a result, many music related to the event can be reproduced.

FIG. 4 is a flowchart showing the operation of the distribution system 1.
As described above, the terminal device 5 has various functions such as a call function and a data communication function, executes the operation mode for each function, and executes the operation of FIG. 4 when the automatic music selection mode is executed. That is, the control unit 6 determines whether or not the current operation mode is the automatic music selection mode (step S11). If the current operation mode is the automatic music selection mode (step S11; Yes), the music piece is communicated with the Web server 21. It is determined whether or not the function of receiving (downloading) data is valid (step S12). When the downloading of the music data is set to be valid (step S12; Yes), the control unit 6 refers to the user profile stored in the attribute DB 82 (step S13), and is further stored in the music library 81. The reproduction history information being recorded is referred to (step S14). Subsequently, the control unit 6 accesses the Web server 21, performs authentication with the Web server 21, and transmits information extracted from the user profile and the reproduction history information to the Web server 21. Here, the Web server 21 selects music data highly relevant to the information extracted from the user profile and the reproduction history information by the control unit 6 and causes the terminal device 5 to download it (step S15). Further, in response to the request transmitted from the Web server 21, the control unit 6 determines whether or not the terminal device 5 is set to be capable of CM distribution (step S16).

  The terminal device 5 is configured to be able to set by user operation whether to download and play dialogue data including CM audio, which is advertisement audio of a company, product, or service, or to reject dialogue data including CM audio. Yes. For example, dialogue data including CM audio is accompanied by the privilege that dialogue data that is usually provided for a fee can be used free of charge, or music data provided for a fee can be downloaded for free. Instead of receiving, the user can set whether to accept or reject line data including CM audio, and the setting contents are stored in the setting table 85.

  The control unit 6 refers to the setting table 85 to determine whether or not speech data with CM sound is permitted. When the speech data with CM sound is permitted (step S16; Yes), the data acquisition unit 73 With this function, the Web server 21 is requested for speech data with CM voice, and the CM voice dialogue data is downloaded (step S17). The control unit 6 registers the downloaded music data and CM-attached dialogue data in the playlist (step S18).

  On the other hand, when downloading of music data is set to invalid (step S12; No), and when it is set to reject line data with CM audio (step S16; No), the control unit 6 Automatic music selection processing for selecting music data stored in the library 81 is performed (step S19), and the selected music data and dialogue data are registered in the playlist by the function of the reproduction management unit 71 to create a playlist ( Step S18).

Subsequently, the control unit 6 refers to the appearance frequency of the dialogue data set in the setting table 85 (step S20), and determines whether or not the appearance frequency of the dialogue data is the same as the number of songs (step S21). . In step S18, the same number of pieces of music data as the line data are registered in the playlist. Therefore, when the frequency of appearance of the line data is not the same as that of the music data (step S21; No), the set frequency of the line data is satisfied. The similar music data is selected by the function of the selection processing unit 72 (step S22). In step S22, the selection processing unit 72 selects music data that meets the following conditions based on, for example, music already registered in the playlist.
Condition 1: Same condition as step S15 or step S19.
Condition 2: The music data already registered in the playlist and a part of the attributes (artist, tempo, energy, genre, age released as new music, etc.) must match at least a predetermined number.
Condition 3: The music data already registered in the playlist and one or more designated among the attributes match.
In step S <b> 22, the control unit 6 selects a required number of pieces of music data from the music data stored in the music library 81 in accordance with preset conditions as in the above example. The selected music data is registered in the playlist, and the control unit 6 proceeds to step S23.
Moreover, when the appearance frequency of dialog data is the same number as music data (step S21; Yes), the control part 6 transfers to step S23.

In step S <b> 23, the control unit 6 uses the function of the reproduction management unit 71 to take in the playlist and start reproducing the music data and the dialogue data.
The reproduction management unit 71 refers to the first data in the playlist (step S24) and determines whether it is dialogue data or music data (step S25). When the referred data is music data (step S25; No), the reproduction management unit 71 determines whether or not the music data is downloaded (step S26). When this music data is music data downloaded to the terminal device 5 from the Web server 21 (step S26; Yes), the reproduction management unit 71 relates the music data to the time and the location where the terminal device 5 is located. It is determined whether or not the music data is to be played (step S27). Specifically, it is determined whether or not an attribute relating to time or place is set as the attribute of the music data. When the music data is related to the time or place (step S27; Yes), the reproduction management unit 71 changes more than a predetermined amount in the time when the music data is selected and the current time and the location where the terminal device 5 is located. (Step S28), if there is a change greater than or equal to a predetermined value (step S28; Yes), the music data is skipped (step S29), and the play list is returned to step S24. Get the next data of.

  Further, the reproduction management unit 71, when the music data referred to in the playlist is not downloaded music data (step S26; No), or when the music data is not related to the time or the location where the terminal device 5 is located (step S27; No). ), And when the music data is music data related to time and place, and there is no change more than a predetermined time and place when the music data is selected (step S28; No), The process proceeds to step S30.

On the other hand, when the referred data is dialogue data (step S25; Yes), the reproduction management unit 71 determines whether or not the dialogue data is dialogue data related to the time or the location where the terminal device 5 is located. It discriminate | determines (step S31). Specifically, it is determined whether or not attributes relating to time and place are set as attributes of the dialogue data. When the dialogue data is related to time or place (step S31; Yes), the reproduction management unit 71 changes the time when the dialogue data is selected and the current time and a predetermined change or more in the location where the terminal device 5 is located. (Step S32), and if there is a change more than a predetermined value (step S32; Yes), this dialogue data is changed to general dialogue data not related to time or place. (Step S33), the process proceeds to Step S30.
In addition, when the dialogue data referred to is not dialogue data related to the time or the place where the terminal device 5 is located (step S31; No), it is dialogue data related to time or location, and the dialogue data is selected. When there is no change more than the predetermined time and place from when it was made (step S32; No), the process proceeds to step S30.

  In step S30, the playback management unit 71 plays back the speech data or music data being processed, and determines whether or not the remaining number of data in the playlist is 1 after the playback of this data or a predetermined time before the end of playback. It discriminate | determines (step S34). If the remaining number of data in the playlist is not 1 (step S34; No), the reproduction management unit 71 returns to step S24 and refers to the next data. On the other hand, when the number of remaining data in the playlist is 1 (step S34; Yes), since the last data of the playlist being reproduced has been reproduced, the reproduction management unit 71 performs another play. The presence / absence of a list is determined (step S35). Here, when there is another playlist (step S35; Yes), the playback management unit 71 returns to step S23 to acquire another playlist and continue playback, and when there is no other playlist. (Step S35; No), this processing is terminated.

  Through the above-described operation, the distribution system 1 selects data from the music data and dialogue data stored in the music library 81 built in the terminal device 5 or the music data and dialogue data stored in the DB 24 into the playlist. The terminal device 5 reproduces the data in the order of the playlist. At this time, when selecting music data or dialogue data having an attribute related to the time, time zone (including day) or the location where the terminal device 5 is located, the music data or dialogue data has been selected. It is determined whether or not the time or place has changed more than a predetermined value. If there is a change more than a predetermined value, the reproduction of the music data is skipped, and the line data is replaced with general-purpose line data. For this reason, music data and dialogue data that do not match the time of reproduction and the position of the terminal device 5 are not reproduced.

5 and 6 are flowcharts showing in detail the automatic music selection process executed in step S19 of FIG. The following automatic music selection processing is executed by the function of the automatic music selection processing unit 7 provided in the control unit 6.
The automatic music selection processing unit 7 determines whether or not the conditions for selecting dialogue data and music data have been acquired by the data acquisition unit 73 (step S41), and if the selection conditions have not been acquired (step S41). No), the selection condition is acquired by the function of the data acquisition unit 73 (step S42), and the process returns to step S41.
