     (나) 해결하고자 하는 과제 
     : 현재 아파트 홍보물(전단지)의 무질서한 배포와 범람으로 인하여 입주민과 관리실에서 지저분한 주위환경 때문에 골머리를 앓고 있으며 아파트 입구에 불법 전단지 배포시 신고하겠다는 문구가 각 아파트마다 붙어 있지만 실행되지 않고 있습니다. 이에 깨끗하고 질서정연한 홍보를 할 수 있도록 여건을 조성해 서로에게 도움이 될 수 있도록 문제를 해결하고자 하는 부분입니다. 
     (다) 과제의 해결수단 
     : 도면과 같이 홍보물(전단지)함을 만들어 홍보업체는 지정된 함에 홍보물을 꽂고 입주민들은 홍보물을 보고 필요가 없을시 바닥에 버리지 않고 수거함에 넣게 되며 기간이 지난 홍보물은 카바를 들어 꺼내어서 재활용으로 처리하는 시스템입니다. 
     각 아파트마다 규격이 다르고 활용공간이 다르기 때문에 맞춤식으로 공급하고 안전성과 미관을 헤치지 않는 아름다움까지 강조할 수 있도록 계속 연구중입니다. 
     (라) 효과 
     : 입주민과 의논하여 아파트 한곳을 선별 샘플을 설치한 결과 입주민은 깨끗해서 만족하고 관리실은 관리가 한결 편해졌으며 홍보업체는 오히려 매출이 늘어나서 환영하고 있으며 전 아파트로 확산해 줬으면 하는 바람을 저희 업체에 전해왔습니다. 
     
     1. 재질은 아크릴, 나무, 스텐레스, 알루미늄등 안전하고 산뜻한 것으로 상황에 따라 바뀔 수 있다.   2. 사이즈 및 규격은 각 아파트의 특성(공간활용)에 따라 변할 수 있다.   3. 여러 가지 악세사리(보조,보강)는 사용하기 편리한 방법으로 변할 수 있다.   4. 재질에 따라 색상 변화를 줄 수 있다.   5. 안전성과 설치의 신속성을 위하여 조립식으로도 가능하다.

Abstract: A method and an apparatus for decoding a video signal are provided to confirm whether the present picture is used in point-to-point prediction and to transmit the necessary information according to the confirmation result. A parsing member(100) performs parsing by the NAL(Network Abstraction Layer) unit to decode a received video image. The parsed bit stream is entropy-decoded through an entropy decoding member(200) so that the coefficient and motion vector and the like of each macro block are extracted. An inverse quantization/inverse conversion member(300) multiplies a constant to the received quantized value, obtains the converted coefficient value, and inversely converts the coefficient value so that a pixel value is restored. An intra prediction member(400) performs a prediction within a screen from the decoded sample within the present picture by the restored pixel value. A de-blocking member(500) performs a de-blocking operation to the coded macro block to reduce a block distortion phenomenon. A decoded picture buffer member(600) stores and opens the coded pictures to perform the prediction between screens. An inter prediction member(700) performs the prediction between screens by the reference picture stored in the decoded picture buffer member.
