Abstract

본 발명은 멀티미디어 신호합성방법 및 신호합성장치에 관해 게시한다. 종래의 방법으로는 사각형이 아닌 비디오는 구현하지 못하거나 또는 구현할지라도 원하지 않는 비디오가 구현되었으나, 본 발명에서는 판별색요소와 실효비디오영역 표시신호를 이용한 신호합성방법을 이용함으로써 원하는 비디오를 정확하게 구현할 수 있다.The present invention relates to a multimedia signal synthesizing method and signal synthesizing apparatus. In the conventional method, although a non-rectangular video may or may not be implemented, undesired video is implemented. However, in the present invention, the desired video can be accurately implemented by using a signal synthesis method using a discriminant color element and an effective video region indication signal. have.
