Abstract

복수의 비디오 공급원으로 부터의 비디오 정보를 처리하여 복수의 직사각형 영역을 갖는 비디오 영상을 제공하는 비디오 합성 기술이 개시되었다. 각각의 직사각형 영역은 복수의 비디오 공급원들 중 특정 공급원으로 부터의 비디오 정보를 디스플레이한다.
각 비디오 공급원으로 부터의 비디오 정보는 입력 디지탈 비트열의 형태이다. 제1비디오 공급원으로 부터의 디지탈 비트열은 제1비트 속도를 갖고, 제2비디오 공급원으로 부터의 디지탈 비트열은 제2비트 속도를 갖는데, 이때 제1비트 속도는 제2비트 속도와 같을 수도 있고 같지 않을 수도 있다. 입력 디지탈 비트열은 모든 입력 디지탈 비트열을 공통 비트 속도로 변환하는 속도 정합 회로에 공급된다. 속도 정합회로의 출력은 특정 디지탈 비트열로 부터의 비디오 정보를 복합 비디오 영상에 대응하는 직사각형 영역에 위치시키는 동기화 및 다중화 회로로 공급된다.
