IPTV(Internet Protocol Television) is an innovation technology to lead the new media age. Internet protocol television (IPTV) is a next generation television converged with the Internet which are delivered portal services such as information search, games, movies, home shopping and banking. Generally, service quality affects to adopt or use these technologies. Quality of experience (QoE) is more issue to be considered than service quality because of the technological restriction and limitation that IPTV is accessed by the Internet. The QoE is defined as the cognitive and experienced quality measured with users through an experiment and is conceptually related to service quality. The objective of this paper is to suggest a methodology to measure the QoE of IPTV using a user testing. We find significant factors affecting QoE of IPTV through an exploratory study and measure QoE scores. We found the nine factors of graphics, picture, accuracy, access method, quality of contents, usability, security, and performance important for QoE. The QoE scores of picture, graphics, and quality of contents gained over the average score, but the overall score for IPTV service providers was not high and the QoE needs to be improved.

뉴미디어 시대의 새로운 혁신기술로 IPTV를 들 수 있다. IPTV는 텔레비전과 인터넷이 융합된 뉴미디어로 TV기능을 가지면서도 인터넷에 접속하여 정보 검색, 게임, 영화, 홈쇼핑, 홈뱅킹 등 포털 서비스를 받을 수 있는 차세대 TV이다. 이러한 혁신기술들의 채택과 사용에 서비스 품질은 중요한 영향을 미친다. IPTV는 일반 TV와 달리 기술적 제약 때문에 서비스 품질보다 체감 품질이 더욱 중요시 된다. 체감 품질은 사용자가 본원적으로 경험하고 인지하는 품질로 최종 사용자를 대상으로 시험하고 측정하는 품질이다. 본 연구는 IPTV의 체감 품질 측정 방법론을 제안하는 것이 목적이다. 탐색적 방법을 사용하여 체감 품질에 영향을 미치는 요인을 발견하고 사용자 테스트라는 실험적 방법을 사용하여 체감 품질을 측정한다. 우리는 요인분석을 통하여 9개의 체감 품질 요인(그래픽, 화질, 정확성, 접근도구, 콘텐츠의 질, 사용성, 보안성, 성능)을 발견하였다. IPTV 서비스 제공자를 대상으로 측정한 체감 품질 점 수는 화질, 그래픽, 콘텐츠의 질을 제외하고는 전반적으로 높지 않아 개선이 요구된다.
