Abstract

본 발명은 와이드화면 영상신호의 선택적 부호화방법 및 그 장치에 관한 것이다. 본 발명은 16:9화면의 영상신호에서 매 프레임마다 4:3화면크기의 영역을 선택적으로 부호화한다. 이때, 선택되지 않은 영역이 이전과 이후의 프레임에서 선택되지 않는 영역과 중복되지 않도록 하며, 영상신호를 재생할 때 부호화되지 않은 영역의 영상신호는 이전 프레임의 동일 영역의 데이터로 대체한다. 이와 같은 본 발명은 4:3화면을 위한 트랙구조를 변경하지 않고도, 16:9화면의 영상신호를 기록할 수 있어 화면비가 다른 영상신호에 대해 호환성을 갖는 기록매체 및 DVCR을 제공하는 효과를 가져온다.The present invention relates to a method and apparatus for selectively encoding wide screen video signals. The present invention selectively encodes an area of 4: 3 picture size per frame in a video signal of a 16: 9 picture. At this time, the unselected area is not overlapped with the unselected area in the previous and subsequent frames, and the video signal of the unencoded area is replaced with the data of the same area of the previous frame when the video signal is reproduced. The present invention provides a recording medium and a DVCR that can record video signals of a 16: 9 screen without changing the track structure for a 4: 3 screen and have compatibility with video signals of different aspect ratios .
