Abstract

Recently, access networking BroadBand the high performance of the video equipment to the Internet via voice, video, multimedia services, such as dealing with the media information dissemination is becoming increasingly attracting attention. More video devices and network environments in the future to keep pace with the high-quality video using the form dealing with an increasingly diversified and shall utilization is expected. Among them, video encoding technology, image compression encoding technology of information technology is one of the central role. Video coding technology that requires a vast amount of information contained in the video signal and the appropriate amount of information to eliminate redundancy as the efficiency of the digital code representing video signal is developed as a technology is going. Therefore, this study applied to video coding mode selection in the cost evaluation methods to examine and to maximize the coding efficiency and the proposed method compared to the conventional method was confirmed excellence.

최근 액서스망의 브로드밴드화와 영상기기의 고성능화에 따라 인터넷을 통한 음성, 영상 등의 미디어 정보를 다루는 멀티미디어 서비스가 주목받고 있으며 점차 보급되어 가고 있다. 앞으로 더욱더 영상 기기나 네트워크 환경에 발맞추어 고품질의 영상을 다루고 이용하는 형태가 점점 다양화되고 활용화 되리라 예측된다. 그 중에서도 동영상 부호화 기술 즉, 영상 정보의 압축 부호화 기술은 중심적인 역할을 하는 기술 중의 하나이다. 동영상 부호화 기술은 방대한 정보량을 필요로 하는 영상 신호 중에 포함되어 있는 용장성을 배제하고 적절한 정보량을 디지털 부호로서 효율인 영상 신호를 표현하는 기술로서 발전되어 가고 있다. 따라서 본 연구는 동영상 부호화에서의 모드 선택에 적용하는 코스트 평가 방법을 검토하고 부호화 효율을 최대화하기 위해 방법을 제안 하고자하며 이를 기존 방법과 비교해 우수성을 확인하였다.
