Abstract

본 발명은 원격에서 영상회의를 할 수 있는 시스템에서 서버시스템에서 클라이언트시스템의 영상구조를 최적화된 크기의 영상으로 조절하여 전송하는 방법과 시스템에 관한 것으로, (a) 어느 하나의 클라이언트시스템의 제어부로부터 영상크기와 좌표를 포함하는 영상구조의 변경을 서버시스템의 주제어유닛으로 요청하는 단계; (b) 상기 주제어유닛은 현재 영상회의 모니터로 출력되는 영상구조의 변경을 요청한 클라이언트시스템 제어부의 요구에 부합되도록 변경하여 각 클라이언트시스템 제어부로 전송하는 단계; (c) 상기 제어부에서 리사이징부의 영상크기를 변경시키고, 엔코딩부를 초기화시키는 단계; (d) 상기 제어부는 엔코딩부에서 변경된 영상신호를 송수신부를 거쳐 서버시스템으로 전송하는 단계; (e) 상기 서버시스템의 주제어유닛은 디코딩모듈을 초기화시키고 수신된 영상신호를 디코딩시키는 단계; (f) 상기 주제어유닛은 변경된 영상구조를 기준으로 렌더링모듈을 통해 영상회의 모니터에 영상이 출력되도록 하는 단계;를 포함하여 이루어진다.
