FIG. 3 is a data map for storing, matching, and outputting a selected song or genre and mood information corresponding thereto according to the present invention.

The present invention relates to a karaoke system for displaying a background image information corresponding to a genre or song of a song selected by distinguishing a song by genre or song in an optical karaoke system.

In general, a song accompaniment system is a device that processes organically while synchronizing three kinds of accompaniment information, subtitle information, and video information. The accompaniment information is data of a Midi (Music Instrument Device Interface) standard and has an average capacity of 30k to 120k bytes per song. Subtitle information consists of song lyrics code and font. Character fonts are typically 512 bytes long in Korean Hangul. There are two kinds of video information: still picture and moving picture. Still picture having the quality of TV broadcasting level requires 128k bytes per screen and moving picture requires 1.2Mbps data capacity.

When the song accompaniment system is set, the Midi data is transmitted to the sound source device at the speed of the song. The sound source device plays the accompaniment music according to the Midi data and outputs the subtitles on the screen. It also changes the color of the subtitles as the music plays and outputs new subtitles. This is performed by a process of outputting a text font according to the song lyrics code to a certain place on the screen, and also changing the color of the printed text font according to the speed of music playing. It also outputs a still image or video on the screen.

Music performances and subtitles should be precisely timed, synchronized. When using still image as wallpaper, user should output one screen every 2-3 seconds so that users do not feel bored. In case of using video, it maintains 1.2Mbps transmission speed to prevent screen disconnection. do.

Meanwhile, as a large capacity / high speed optical disc system has been developed, a digital song accompaniment system has been implemented using a disc. In a digital song accompaniment sequence using a disc, a large amount of video information is usually recorded on a disc, and subtitle and accompaniment information with a relatively small amount of data is stored on a ROM or the like.                         

Accordingly, in the digital song accompaniment system using a disc, image information is reproduced according to the music playing speed, and the caption information stored in the ROM is overlaid on the background screen.

As described above, in the digital song accompaniment system using a disk, in the conventional case, image information irrespective of the genre of music or the atmosphere is often displayed as a background screen. That is, when the user selects music, video information is reproduced sequentially from the start of the disc, while there is no special order. Therefore, even if the user selects a music of a certain genre, the video information reproduced on the disc may be displayed as a background screen that is completely different from the selected music.

An object of the present invention is to provide a karaoke system for matching the selected genre or music and the atmosphere of the background screen.

In other words, by storing the karaoke information in the list part of Mood_1, Mood_2, ..., Mood_n, the music information and the background image can be matched using the index of the music information and the information (index) of the Mood information. To do that.

In the karaoke system according to the present invention for achieving the above object, the image and song matching device, including an input unit for inputting at least one data and command, and at least one storage medium, and stores audio, video and karioke information And memory means for storing one or more data corresponding to the information input through the input unit, karaoke processing means for processing the mood information corresponding to the input information to be displayed on the display means, and the stored means. A karaoke apparatus comprising audio processing means for outputting data, and a control unit connected to and controlling the components, the karaoke apparatus including a plurality of mood information in a list portion of the karaoke information, Indicates.

In one embodiment of the present invention, the plurality of mood information in the list portion of the song information and the karaoke information and the mood information in the video information in the music file are stored in respective binary forms and matched for reproduction.
