Abstract
Description
Claims (2)
- 영상 기록재생시스템의 복호화장치에 있어서, DC계수 또는 DC와 소정의 AC계수로 구성된 가변속 영상데이타가 기록된 비데오테이프로부터의 가변속데이타를 독출하여 디스플레이하기 위해 복호화하는 가변속데이타 복호화장치를 포함하는 영상기록재생시스템.
- 제1항에 있어서, 상기 가변속데이타 복호화장치는 상기 비데오테이프로부터의 가변속 영상데이타를 인가받아 에러정정을 하는 오류정정부(ECC); 상기 오류정정부로부터 인가되는 가변속데이타를 소정 크기의 블럭 단위로 IDCT변환하는 제1IDCT부; 상기 가변속데이타 기록시 특졍계수만을 추출하여 소정 크기의 블럭으로 재구성한 특정계수를 상기 제1DCT부로부터 인가받아 부호화시 추출했던 자기블럭의 계수자리로 되돌려주는 블럭재구성부; 상기 블럭재구성부를 통해 복구된 영상데이타의 각각의 블럭들을 IDCT하는 제2IDCT변환부; 상기 제2IDCT변환부를 통해 인가되는 영상데이타를 디스플레이하기위한 형식으로 블럭을 다시 포매팅하는 불럭리포매팅부를 포함하는 것을 특징으로 하는 가변속데이타 복호화장치.
