Video song accompaniment system and control method thereof

摘要

The present invention relates to a video footbal accompaniment system and a control method thereof. In the conventional video footbal accompaniment system using a PCM sound source chip, a CPU, a memory and an interface circuit for controlling a sound source chip are used. A video accompaniment system for generating an audio sound, comprising: a CPU for controlling a sound source chip; The CPU of the tone generator chip controlling CPU and the interface circuit for communication with the main CPU are removed and the main CPU reads the arrangement data of the entire system by initialization and song selection and controls the video processing of the subtitles and the background And controlling the sound source chip based on the arrangement data according to the selected song to control generation of a digital singer signal in a time-division manner, wherein the main CPU controls the first process and the second process to be constant And an interrupt generation means for generating an interrupt so as to perform time division in time intervals, thereby reducing the number of elements and enabling accurate accompaniment without delay time.
