Title
(KO) 비디오 코딩 및 디코딩을 위한 장치, 방법 및 컴퓨터 프로그램
Abstract
(KO)
압축되지 않은 구성 프레임을 제 1 인코딩된 픽처로 인코딩하는 단계 - 상기 인코딩은 결과적으로 재구성된 제 1 픽처를 또한 생성하고 구성 프레임은 제 1 재구성된 픽처 내에 유효 픽처 영역을 가짐 - 와, 상기 인코딩의 일부로서 다음 중 하나를 수행하는 단계를 포함하되, 다음 중 하나는, 유효 픽처 영역 외부에 적어도 하나의 샘플 값을 삽입하여 재구성된 제 1 픽처에서 구성 프레임에 대한 경계 확장부를 형성하는 단계, 또는 유효 픽처 영역 외부의 샘플 위치를 포화하거나 랩핑 오버하여 유효 픽처 영역 내에 있게 하는 단계인 방법이 제공된다. 또한, 인코딩된 픽처를 수신하는 단계와, 유효 픽처 영역을 갖는 픽처의 재구성된 구성 프레임을 형성하기 위해 인코딩된 픽처를 디코딩하는 단계와, 다음 중 어느 하나를 수행하는 단계를 포함하되, 다음 중 어느 하나는, 패딩된 참조 픽처를 생성하기 위해 유효 픽처 영역 외부의 영역을 채우는 단계 - 채워진 영역은 경계 확장부를 형성함 -, 또는 디코딩 시 유효 픽처 영역 외부의 샘플 위치를 참조할 때, 샘플 위치가 유효 픽처 영역 내에 있도록 포화되거나 랩핑 오버되는 것을 결정하는 단계인 방법이 제공된다.
