The movable member includes a coupling pipe(310), a second friction member(313) made of a super-hard alloy and a third friction member(315) made of a super-hard alloy. The coupling pipe includes an outer vertical wall(315b), an insertion groove(313a) formed in the outer vertical wall, and an inner vertical wall(315a) formed in the insertion groove while facing the outer vertical wall. The second friction member is inserted into the insertion groove to be in close contact with the friction member of the fixed member.

Abstract: 본 발명은 디지털 영상 데이터를 재생하는 디바이스 환경, 특히 개인 휴대 기기와 같은 유,무선 네트워크 환경에서 영상 데이터 스트림의 에러 검출 방법에 관한 것으로서, 입력된 영상 데이터 스트림에 포함된 에러의 유무를 판단하고, 에러가 발생한 것으로 판단된 경우 입력된 영상 데이터 스트림의 복호화 과정에서 생성된 변환 계수의 패턴의 유사성을 판단하고, 유사성 판단에 기초하여 발생한 에러의 시작 위치를 검출함으로써, 디코더 자체적으로 에러의 위치를 정확하게 판단할 수 있으며 복원 방식의 오류 은닉 기법을 적용함에 있어 대체 복원된 영상의 화질을 보다 향상시킨다.
