보편적으로 확산된 IP 네트워크를 기반으로 신규 사업모델을 창출하기 위한 IPTV 서비스가 전세계적으로 추진되고 있다. 또한, 고품질 IPTV 서비스 제공을 위하여 특히 FTTH를 포함한 가입자망의 광대역화가 빠르게 이루어지고 있다. IPTV 서비스는 통신서비스와 방송서비스의 융합을 특징으로 하며, IPTV 서비스가 제공되기 위해서는 다양한 IP 네트워크 기술, 방송 AV 기술, 서비스제어 기술, 콘텐츠 보호 기술들이 복합적으로 사용된다. 본 기고에서는 IPTV 표준화 동향, 관련 기술, 국내외 서비스 동향, 신규 IPTV 서비스 예 등을 살펴보고, ETRI에서 구축한 FTTH 기반 IPTV 테스트베드를 간략하게 소개한다.
