[0002]

2. Description of the Related Art A so-called karaoke device, in which only an accompaniment such as a song is played and a song is sung according to the accompaniment, has become widespread. It is installed in.

Recently, karaoke has been enjoyed by a wide range of generations, from young to old, and in order to respond to a wide range of requested songs from these users, a large storage device of a central database installed at the head office, Data of many songs used for karaoke, telop data, etc. are recorded, and these data are sent to a karaoke reproducing device (terminal) provided in a plurality of karaoke installed stores through a digital communication line for use by customers. The karaoke system (see Japanese Patent Application No. 2-138332) in which the usage status and the like are recorded in a central database, and further, a plurality of local databases are provided between the central database and the terminal, and a large number of them are provided. A network-type system has been developed that manages the transfer of data to other terminals via local databases. There.

In this case, usually, music data recorded in a memory provided in a database is sent to a terminal for karaoke reproduction through a digital communication line, and the music data is read by the terminal side from the memory provided in the terminal. In combination with the data, the music and the moving image of the requested song are played back.

With such a karaoke system, one piece of software recorded in the central database can be used to access many terminals, new songs can be easily handled, and the usage status of karaoke can be accurately grasped. Small footprint,
There are many advantages such as low initial cost and unlimited number of songs to prepare.

However, the information amount of the image data for one music is much larger than that of the music data, so that the number of music data that can be recorded in the database memory is 3000 to 10000. In contrast,
The number of videos that can be recorded in the memory of the terminal is about 512 to 1024 series, and if the number of music data songs is set to 512 to 1024 songs according to the number of video series, it cannot meet the customer's request, and conversely In order to adjust the number to 3000 to 10000 series in accordance with the number of music data pieces, the moving picture data memory of the terminal must be extremely large in capacity and large in size, which was impossible at a practical cost. In the above and the following explanations, "Video

Thus, an example of a moving image allocating method in the karaoke system according to the present invention configured as described above,
It is as shown in [Table 1] below when displayed in an easy-to-understand manner. Here, the number of songs recorded in the music data recording memory of the database is 9000, and the number of series of moving images recorded in the moving image data memory of the terminal is 550 series. It is assumed that the song number of the music data is "1", the song number of the song data of the 837th request frequency rank is "837", and the song numbers of the music data are numbered according to the request frequency rank. .

[0012]

[Table 1]

That is, for the songs from the 1st to 50th request ranks (50 songs in total), one song corresponds to one series of moving images, and therefore each song uses its own separate moving image. A total of 50 series of movies are used. Also, for the 51st to 150th requested songs (100 songs in total), 2 videos are associated with 1 series of videos,
Therefore, for every two songs, one series of videos will make do
Use 50 series movies. In addition, the request rank first
For the 51st to 300th songs (150 songs in total),
One series of videos is made to correspond to three songs, so every three songs are made up of one series of videos, and a total of 50 series videos are used. In the same manner, the number of songs for one series of videos is increased in the same way as the request rank becomes lower, and the number of request ranks from 6501st to 9000th (total 2500 songs) is 50 songs. Therefore, one series of videos will be supported, so that every 50 songs will be made in time for one series of videos.

Therefore, some examples of this for each music data are as shown in Table 2 below.

[Table 2]

Thus, the genre of the requested song,
That is, the motif of the movie is completely different depending on the genre of the song such as enka, folk song, pop, rock, military song, and the theme of the song such as love, celebration, lyric, hometown, inspiration. It is not desirable to display the video of the above, or to display the image of uplifting battle for the song of broken heart, so the above video allocation method should not be allocated according to the request frequency regardless of the genre of the music. It is recommended to classify the songs by genre and theme, and allocate the song data in each genre or theme such that the request frequency is low so that the number of songs of the music data for one series of moving images is increased.

[0016] Also, some songs having the same request frequency may overlap, or the video contents of a moving image series assigned to a certain song according to the request frequency may not be suitable for the song. Therefore, the allocations shown in [Table 1] and [Table 2] above are merely principles, and a certain degree of rearrangement or modification can be permitted depending on the individual situation.

[0017]

With the above-mentioned structure, since the moving picture is different for each song group (the top 50 songs in the above example) that are requested most frequently and are frequently played, the variety of songs is varied and I never get tired of it, and there are rare occasions to play songs with few requests, so even if I make the same video for several songs,
There are no complaints from customers, so a relatively small number of video series can handle 10 times as many songs, and it is practical enough to use a large-capacity, high-priced video data memory for terminals. Karaoke system can be provided.
