Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a karaoke system.

[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, image data, etc. are recorded, and these data are sent to a karaoke reproducing device (terminal device) provided in a plurality of karaoke installation stores through a digital communication line. A karaoke system (see Japanese Patent Application No. Heisei 2-138332), which is used by customers and records the usage status in a central database, and a plurality of regional databases are provided between the central database and terminals. A network-type system that has been established and manages the transfer of data to and from a large number of terminals via a local database. There has been developed.

In 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, in this type of conventional digital communication line type karaoke system, the amount of image data to be transmitted / received for one request song is enormous, so that it takes a considerable time to transmit / receive the data, and the digital communication line is required. There is a problem that not only the usage fee increases, but also the response time becomes long when requests are concentrated from a large number of terminals to the database, and the customer is dissatisfied.

[0006]

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and an object thereof is to reduce the amount of data to be transmitted / received, the time required for transmission / reception, and the response to a request. It is to provide a karaoke system that responds quickly and can handle many songs with a small amount of image data.

[0007]

The above-mentioned object is to exclude the image data, which occupies most of the data to be transmitted and received, from the object of transmission and reception, and instead provide a memory in which a large number of moving image element patterns are recorded in the terminal. This can be achieved by a karaoke system configured to select, combine, and reproduce a large number of image element patterns stored therein, based on a combination command signal of images determined according to a song.

Specifically, the karaoke system according to the present invention comprises a database and a large number of terminals for karaoke reproduction connected to the database through digital communication lines.
Each of the terminals is provided with a memory for recording a large number of moving picture image element patterns and a circuit for synthesizing various image element patterns, and the database is provided with a memory for recording music data and telop data, and a circuit for composing music. A memory that stores the combination command signal of the specified image element pattern is provided, and the combination data signal of the music data, the telop data and the image element pattern is sent from the database to the terminal side according to the requested song, and the terminal side Then while playing karaoke music with the sent music data,
Based on the sent telop data, various image element patterns read out from the image element pattern memory based on the sent combination command signal are superimposed by the above-mentioned synthesis circuit to form a completed moving image corresponding to the requested music. It is characterized in that it is configured to be displayed together with telop characters.

It is to be noted that the music data sent from the database is incorporated with a combination command signal of image element patterns determined according to the music, and these are combined in a memory for recording the music data and telop data in the database. It is also possible to omit the memory for recording only the combination command signal of the image element patterns by recording in the memory.

[0010]

With the above-mentioned configuration, it is not necessary to send a huge amount of image data from the database to the terminal, and the image data can be reproduced by combining those read out from the image element pattern memory in the terminal. The amount of data to be processed is significantly reduced, the time required for sending and receiving is greatly shortened, the response to requests is quick, and various images can be expressed simply by changing the combination. It is possible to provide a karaoke system compatible with the above.
