Abstract

여러 가지 포맷을 갖는 텔레비전 방송 신호를 수신 및 디스플레이하는 텔레비전 시스템(100) 및 디스플레이 방법에 대해 개시되어 있다. 텔레비전 시스템 (100)은 공통 디스플레이 디바이스 상에 디스플레이하기 위해 여러 가지의 수신된 화상 포맷을 재구성한다. 화상은 데이타가 텔레비전(100)에 의해 샘플되는 비율을 바꾸므로써 수평적으로 재구성된다. 화상은 한 화상의 라인 수를 바꾸는 수직 스케일링 알고리즘을 사용해서 수직적으로 재구성된다. 포맷 탐지는 텔레비전 방송 신호의 수직 간격에 포함된 정보를 디코딩하거나 또는 각 프레임에 있는 라인수를 계수하므로써 자동 수행될 수 있다. 입력 포맷은 관찰자에 의해 지시될 수 있다.
