초록

무크(Mook) 서비스 정착과 교육부의 원격 수업 확대 정책에 힘입어 대학을 중심으로 온라인 수업이 일반화하고 있으며, 출석 정규 수업의 형태도 일부 원격 방식으로 전환되는 추세이다. 본 논문은 이러한 교육 환경에서 필요한 교육용 콘텐츠를 제작하는 도구에 관한 것으로 이에 필요한 오디오 동기화 방법과 편집 알고리즘을 제안하였다. 제안한 알고리즘을 노트북 등 일반적인 PC 환경에서 그 성능을 측정하였다. 평가 결과, 안정적인 CPU와 Ram 사용량을 보였다. CPU 사용은 평균 9.3% 점유율을 나타냈고 Ram은 평균 87Mega바이트의 안정적인 사용량을 기록하였다(CPU 2.60GHz, 820*600 영역 기준). 본 제안하는 방식을 사용하면 손쉽게 자기 PC로 원격교육을 진행할 수 있을 것으로 판단된다.

On-Line Lectures are becoming more common due to the MOOK service and the expansion of national policy in Korea. Especially, It is being changed to new remote mixed style from traditional lecture in universities. We propose and implement a remote contents making tool with audio synchronization function based on more with less resources. To implement our proposed algorithm, we design an interactive interface to assign multiple cutting intervals and convert an input video to print a new result. In experimental, we can confirm our algorithm works properly with average performance value 9.3% cpu share ratio and 87mega byte ram usage(CPU 2.60GHz, 820*600 Area).
