The song accompaniment system configured as described above is a device for organically processing three kinds of accompaniment sound information, subtitle information, and video information while synchronizing. 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.
