Abstract
본 발명은 CIF영상신호 변환기에 관한 것으로, 특히 표준 NTSC 영상신호를 국제전신전화 자문위원회(CCITT)에서 규정한 CIF(Common Intermediate Format)영상신호로 변환할 수 있는 CIF 영상신호 변환기에 관한 것이다.The present invention relates to a CIF video signal converter, and more particularly, to a CIF video signal converter capable of converting a standard NTSC video signal into a CIF (Common Intermediate Format) video signal defined by the International Telephony Advisory Committee (CCITT).
본 발명에 의한 CIF 영상신호 변환기는 입력된 NTSC 영상 데이터를 비데오 RAM에 순차적으로 어드레싱하여 저장한 후, 비데오 RAM에 저장된 NTSC 영상데이타를 5 : 3 의 비로 어드레싱하여 읽어 냄으로써 NTSC 영상신호를 CIF 영상신호로 변환할 수 있다.The CIF video signal converter according to the present invention sequentially stores the input NTSC video data in the video RAM and stores the NTSC video signal by reading the NTSC video data stored in the video RAM at a ratio of 5: 3 to read the CIF video signal. Can be converted to
