Abstract
방송과 통신 기술의 발전에 의해 방송통신융합의 대표적인 서비스인 IPTV가 선보이게 되었다. IPTV는 인터넷의 IP 프로토콜을 이용하여 TV를 통하여 방송 프로그램을 시청하면서 다양한 통신 서비스를 이용할 수 있는 특징을 갖는다. 초기의 IPTV는 유선망을 기반으로 한 양방향 멀티미디어 방송 서비스인 IPTV 1.0으로써 거실에서 보는 TV 서비스 개념을 따르고 있어 이용자 입장에서는 기존 방송 서비스와 커다란 차별성을 갖기 어려운 부분이 있다. 그러므로, 유선과 무선이 통합된 환경에서 언제 어디서나 고품질의 콘텐츠를 생성, 전달, 소비하는 4A(Any-where, Any-time, Any-device, Any-content) 서비스를 제공하기 위한 유무선 통합 환경의 IPTV 2.0의 필요성이 대두되고 있다. 따라서, 본 논문에서는 IPTV 2.0의 개념을 설명하고, IPTV 1.0과의 차별성, 그리고 대표적인 IPTV 2.0의 응용 서비스 예를 기술하였다. 또한, IPTV 2.0 서비스를 실현하기 위해 제안하고 있는 핵심기술들에 대해 설명하고, 이러한 기술을 연계한 통합 테스트베드 설계 구성도와 각 기술별 서비스 추진 전략에 대해 기술하였다.
