The music distribution unit 311 accepts the designation of a playlist (S421), and sets the start music ID included in the playlist information of the designated playlist as the playback ID (S422). The music distribution unit 311 reads component music data corresponding to the playback ID from the music library 331 (S423), and sets the next music ID in the list information as the playback ID (S424). The music distribution unit 311 transmits the read component music to the streaming server 2 (S425). As a result, the music is distributed from the streaming server 2 to each viewer terminal 1 by streaming.

The comment acquisition unit 312 acquires comments posted by the viewer using the viewer terminal 1 from the streaming server 2 (S426). Comments can be obtained, for example, by calling an API provided by the streaming server 2.

The switching determining unit 313 reads comments posted during the determination period from the comment storage unit 334 for each piece of condition information stored in the condition storage unit 333 (S427), and determines whether the read comment satisfies the conditions of the condition information. It is determined whether or not (S428). Whether a comment satisfies the condition can be determined, for example, by counting the number of comments included for each keyword and determining whether the counted number exceeds a predetermined threshold.

If the comment satisfies the condition (S429: YES), the switching determining unit 313 sets the next song ID included in the condition information as the playback ID (S430).

By performing the above processing on the condition information, the next song ID of the condition information that finally satisfies the condition is set as the playback ID.

If the transmission of the music data being distributed has not been completed (S431: NO), the process from step S425 is repeated.

When the transmission of the music data being distributed is completed (S431: YES), if the music ID is set in the playback ID (S423: YES), the music distribution unit 311 repeats the process from step S423, and sets the playback ID. If the music ID is not set (or if a NULL value is set) (S431: NO), the music distribution unit 311 concludes that the playlist has been played and ends the process.

FIG. 9 is a diagram showing an example of a screen displayed on the viewer terminal 1. In the example of FIG. 9A, a video 511 is displayed based on music data distributed from the streaming server 2. Note that if the music data is audio data, a still image may be displayed instead of the video 511, or a video obtained from a source other than the music data may be displayed in the video 511. . Furthermore, comments 512 posted by the viewer operating the viewer terminal 1 or the viewer operating another viewer terminal 1 are displayed on the screen.

Here, if the condition storage unit 333 contains condition information including the condition that the name of a song such as "Fairy Empire" is the one that has been posted the most among songs that have been posted a predetermined number of times or more, then ) If the keyword "Fairy Empire", which is also displayed in the example above, is included most often in the posted comments, the song "Fairy Empire" will be distributed as shown in Figure 9(b). Ru. In addition, if a comment that includes the planned song name is not posted or the number of posts falls below a predetermined number, the next song ID in the list information is set as shown in FIG. 9(c). The songs that were posted will be distributed.

As described above, the music distribution system of the present embodiment delivers a linear video in which component music data set as a playlist is continuously transmitted to the viewer terminal 1 via the streaming server 2, and also distributes the component music data The next song to be distributed can be dynamically changed in response to comments from viewers during playback. Therefore, it is possible to provide a linear video with different developments depending on the viewer's reaction. Therefore, it is possible to distribute the music without impairing the live feel of the streaming distribution system, even though recorded component music data is used.

Although the present embodiment has been described above, the above embodiment is for facilitating understanding of the present invention, and is not for construing the present invention in a limited manner. The present invention may be modified and improved without departing from the spirit thereof, and the present invention also includes equivalents thereof.

For example, in this embodiment, the songs sent from the distributor device 3 are distributed to the viewer terminals 1 via the streaming server 2, but the songs are directly transmitted from the distributor device 3 to each viewer terminal 1. It can also be distributed.

Furthermore, in this embodiment, the song library 331 stores song files encoded in a format such as MP3, but the song library 331 also stores MIDI data, track information for synthesizing multiple tracks, etc. The information may be stored and dynamically synthesized audio or video based on the information may be transmitted.
