Abstract

본 발명은 MPEG와 관련된 영상신호 재생장치의 영상신호 디코당시 발생하는 동화 노이즈를 제거하여 고화질의 화면을 실현시킬 수 있도록 한 MPEG 디코딩 회로에 관한 것인 바, 그 특징적인 구성으로는 MPEG 디코딩수단의 디지탈 영상데이터의동화 노이즈가 발생하는 부분을 검출하여 일정한 신호로 출력시키는 동작 검출수단과, 상기 MPEG 디코더부에서 복원된 디지탈 영상 데이터상의 동화 노이즈를 상기 동작 검출수단의 검출 신호에 의해 제거하여 상기 디지탈/ 아날로그 변환수단으로 동화 노이즈가 제거된 영상 데이터를 출력하는 적응 노이즈 제거수단으로 구성함에 있다.The present invention relates to an MPEG decoding circuit capable of realizing a high quality screen by removing moving picture noise generated during video signal decoding of an MPEG related video signal reproducing apparatus. Motion detection means for detecting a portion in which moving image noise of digital video data is generated and outputting it as a constant signal; and removing the moving image noise on the digital video data restored by the MPEG decoder by the detection signal of the motion detection means. / Adaptive noise removing means for outputting video data from which moving image noise has been removed to analog converting means.
