Abstract

본 발명은 가요 반주기기에 관한 것으로서, 종래에는 이러한 글자의 필요성과, 여러가지 서체지원등으로 가요반주기기에서 사용하는 폰트의 수가 늘어나는 경우, 또는 중국의 문자 즉, 한자를 가요반주기기에 내장하는 경우에는 대용량의 폰트저장 공간이 필요하게 된다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a flexible half-cycle machine. In the related art, when the number of fonts used in the flexible half-cycle machine increases due to the necessity of such letters and various fonts, or when Chinese characters, ie, Chinese characters are embedded in the flexible half-cycle machine, Requires a large amount of font storage space.

또한 압축 폰트데이타 전용 디코딩부에 의해 기존의 여러가지 압축방법들은 동작방법이 복잡하여 화면 프로세서부만으로는 폰트의 실시간 디코딩을 수행하지 못해 가요반주 제어의 동작이 상당히 어렵게 되는 문제점이 있었다.In addition, the conventional compression method by the compression font data dedicated decoding unit has a problem that the operation of the flexible accompaniment control is very difficult because the operation method is complicated to perform the real-time decoding of the font only by the screen processor unit.

따라서, 본 발명은 상기와 같은 문제점을 해결하기 위해 단순하면서도 효율적인 폰트 압축방법을 제시하므로서, 가요 반주기기의 비디오 오버레이에 사용하는 한글 및 한자 폰트 저장 롬의 크기를 줄이고, 또한 압축 인코딩 및 압축 디코딩을 화면 프로세서에서 수행할 때 전체적인 영상 오버레이 정보의 속도가 별다른 무리없이 진행시키고자 하는 가요 반주기기의 비디오 오버레이 폰트(FONT) 압축 인코딩/디코딩 방법이다.Accordingly, the present invention provides a simple and efficient font compression method to solve the above problems, thereby reducing the size of the Hangul and Chinese character font storage ROM used in the video overlay of the flexible half-cycle period, and also compressive encoding and compression decoding. This is a half-cycle video overlay font (FONT) compression encoding / decoding method that allows the speed of the overall image overlay information to be easily performed when executed in the screen processor.
