Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a music distribution method and a music distribution system for providing music data stored in a music distribution center and enabling music reproduction in a client facility. The music can be produced or extracted by reflecting the environment of the place where the music is reproduced or the preference of the person, and can be distributed.

[0002]

2. Description of the Related Art In the technical field of music distribution, this can be roughly defined into four forms in view of the characteristics of the distribution. The first system is a wired system which is the most popular system in the early days of music distribution. Broadcast can be mentioned. In this system, a plurality of contracted stores are connected to the music distribution center via telephone lines or dedicated lines,
Although music is distributed, it enables a so-called "phone request" in which a store can request a desired music.

The second system continuously distributes music of a specific genre selected by the music distribution center (for example, light music, pop music, jazz, popular music, etc.) and receives the music. Stores that do this use it directly as background music (BGM) or the like. Normally, a plurality of channels in which music is grouped by genre are prepared according to the environment in which music is reproduced, the listener's preference, and the like, so that the receiver can select any channel.

A third system is a so-called "communication karaoke system". A currently popular musical score type karaoke apparatus drives a musical score with music data to generate a karaoke performance sound. Perform the performance. In such a karaoke apparatus, music data is stored in a hard disk or a CD-ROM of the apparatus, and newly announced music data is downloaded and stored in the hard disk or the like each time.
Then, based on the performance request, the music data is read from a hard disk or the like, and the music score is driven to perform a karaoke performance.

A fourth system is a so-called "ringing melody" in a portable telephone, in which a carrier of the portable telephone connects to a carrier base station and prepares a new song or the like prepared for transmission from the carrier base station. Is called and downloaded to the user's own mobile phone so that the user can play the music on the mobile phone and listen to the performance.

[0006]

As described above, the reproduction of music data in the most popular music distribution at present is as follows.
The result of the user's intention to specify a particular song, that is, the song selected based on only the preference of the particular individual is played. On the other hand, when music data is provided unilaterally as background music without reflecting the will of a specific individual, the environment, situation, or listener's preference of the music to be played is, of course, unknown on the music distribution side. In addition, since there is no room for the receiver to select a song, it is impossible to provide an accurate song suitable for the environment or the like.

Although the psychological utility of music in various environments is highly recognized, it has not been easy to analyze individual environments with human labor and to match accurate music. For example, environments that require background music include department stores, hotels, restaurants, airport lobbies, station buildings, exhibition halls, event halls, bookstores, hospitals, etc.
・ There is a very wide variety of music, and the conditions of music for each environment are different.

[0008] On the other hand, individual music tastes vary,
For personal use of music, if you know a few songs that you like and want to select similar songs, refer to the description of the publication or listen to the method of selecting songs It must be repeated, but in reality it is impossible.

For example, if the taste of a certain person's music is "quiet jazz" or "calm chamber music", the music is extracted based on such a request, and if this can be easily listened to, the taste is selected. Matching music can be easily grasped, and the above problem can be solved.

The present invention has been made in order to solve the above-mentioned drawbacks of the conventional music distribution, and determines the conditions of the environment where music is required, the conditions of the user's preference, and the like.
It is an object of the present invention to be able to compose or extract music suitable for the purpose of use and provide it.
