Abstract
지상파 DMB(digital multimedia broadcasting)의 데이터 방송 서비스인 BWS(broadcast website)는 다수의 수신 단말에서 웹 트래픽 없이 방송을 통한 웹사이트 유사 서비스를 제공할 수 있는 데이터 서비스라는 큰 장점이 있지만, 이동 통신 기술 발달로 인해 스마트 폰이나 패드 등 스마트 기기를 통한 모바일 웹 서비스가 보편화된 환경변화로 그 가치를 인정받지 못하고 있다. 최근 방송과 통신을 융합한 하이브리드 방송을 통해 다양한 하이브리드 서비스를 제공하는 기술이 개발되고 있다. 본 논문에서는 BWS를 계층으로 구분하여 전송하는 계층 연동 구조의 BWS를 제안하고, 하이브리드 DMB 데이터 서비스로의 활용 방안을 제시한다. The BWS (broadcast website) data broadcasting service for terrestrial DMB (digital multimedia broadcasting) has a great advantage that it can provide a website like service through broadcast without web traffic to a plurality of receiving terminals. However, the value of BWS has not been recognized due to the development of mobile communication technology and changes in the environment, where mobile web services through smart devices such as smart phones and pads are common. Recently, various hybrid service technologies provided through hybrid broadcasting, a fusion of broadcasting and communications, have been developed. In this paper, we propose a scalable BWS dividing the hierarchy of BWS into transmission layers and present its application for hybrid DMB data broadcasting services.
