Abstract
본 발명은 NTSC 방송의 수직 방향 영상 포맷을 최소한의 메모리를 이용하여 HDTV 모니터의 수직영상 포맷에 맞도록 변환하는 수직영상 포맷 변환장치에 관한 것으로서, 특히 n(여기서, n은 정수)바이트 워드로 구성되는 프레임 메모리와, 상기 프레임 메모리에서 병렬로 출력되는 n 바이트의 데이터를 저장하는 다수의 선입선출(FIFO) 메모리와, 상기 다수의 FIFO 메모리에서 각각 병렬로 출력되는 데이터를 각각 시리얼로 변환하는 다수의 병/직렬 변환부와, 상기 다수의 병/직렬 변환부로부터 각각 출력되는 데이터를 필터링하여 보간한 후 데이메이션을 수행하고 출력속도에 맞춰 출력하는 필터 및 포맷 변환부로 구성되어, 프레임을 변환시 사용되는 프레임 메모리를 n바이트 워드로 구성하여 수직 영상 포맷 변환시에도 이용함으로써, n탭 필터링을 위해 사용하는 라인 메모리의 크기를 줄여 셋트의 사이즈와 비용을 줄이며, 별도의 라인 메모리의 추가 없이 주문형 IC(ASIC) 내부에 구현이 가능하다.The present invention relates to a vertical video format converting apparatus for converting a vertical video format of an NTSC broadcast to a vertical video format of an HDTV monitor using a minimum of memory, and in particular, n (where n is an integer) byte word. A plurality of first-in first-out (FIFO) memories storing n-byte data output in parallel from the frame memory, and a plurality of serially converting data output in parallel from the plurality of FIFO memories, respectively. It consists of a parallel / serial converter, and a filter and a format converter for filtering the data output from the plurality of parallel / serial converter, respectively, interpolating and outputting the data according to the output speed, used for converting the frame The frame memory is composed of n byte words and used for vertical image format conversion. The size of the line memory to reduce reduce the size and cost of the set, this can be implemented within the application specific IC (ASIC) without the addition of extra line memory.
