Abstract

본 발명은 복수의 동영상을 결합할 때 발생하는 비디오 신호와 오디오 신호간의 동기화 오차를 보정하는 동기화 오차 보정 장치 및 방법을 개시한다. 본 발명은 서로 다른 동영상 콘텐츠를 결합함에 있어서, 결합될 동영상의 최초 비디오 신호와 오디오 신호간의 동기화 오차를 저장하고, 복수의 동영상 콘텐츠를 결합할 때, 기존에 비디오 신호와 오디오 신호가 서로 동기화되도록 설정된 최초 동기화 오차가 유지되도록 결합함으로써, 종래기술이 획일적으로 비디오 신호와 오디오 신호를 결합하여 오차가 변경함으로써 비디오 신호와 오디오 신호가 비동기화되어 어색한 동영상이 표현되는 문제점을 해소하였다.
