가입자망의 고도화 및 광대역화가 경쟁적으로 추진되고,이에 따른 신규 서비스도 활성화되고 있는 추세이다. 국내 광통신 산업의 저변 확대와 육성 발전, 차세대 장비 개발, 광가입자망 기반 고품질 서비스 및 플랫폼 개발의 일환으로, ETRI(Electronics and Telecommunications Research Institute)에서는 자체적으로 FTTH(Fiber-to-the-Home) 표준BMT(Bench Mark Test) 테스트베드와 네트워크 운영센터 및 IPTV 서비스 장비로 FTTH 서비스 센터를 구축하고, 통신망 사업자를 통하여 규모 있는 상용 광가입자망을 구축하고 연동하였다. 본 논문에서는 ETRI의 FTTH 서비스 센터에서 송출하는 고화질의 IP 방송이 통신 사업자의 상용 광가입자망을 통하여 가입자에게 전달되고, 가입자가 IP 셋탑으로 출력하는데 있어 QoE(Quality of Experience) 측면에서 나타난 문제를 분석하고 개선한 내용을 기술하였다.
