초록
Best-effort 서비스를 제공하는 IP 기반 네트워크에서 IPTV, WebTV, SmartTV 등의 다양한 실시간 TV 서비스를 안정적으로 제공하기 위해서 효율적인 품질관리가 요구된다. 본 연구에서는 네트워크 관련 QoS 지표와 사용자 관련 QoE 지표를 이용하여 실시간 TV서비스의 영상 품질을 객관적으로 측정하기 위한 NR 방식의 소프트웨어 도구를 제시하였다. 네트워크 관련 QoS 지표를 이용한 객관적 품질 측정은 기존의 상용 계측장비와 비교하였고 타당성을 검증하였다. 또한 상용 계측장비에서 지원하지 않는 사용자 관련 QoE 품질평가 지표를 이용한 객관적 품질측정은 전문가 집단에 의한 주관적 품질측정과 비교하였고 타당성을 검증하였다
Abstract
It should be considered effective quality measurement scheme to stably provide various realtime TV services such as IPTV, WebTV, SmartTV over IP-based networks which provide best-effort services. In this study we have presented No-Reference S/W tools in order to objectively measure video quality of realtime TV services using the network-related QoS metrics and user-related QoE metrics. We have compared with commercially available measuring instruments to verify validity of our objective quality assessment scheme using the network-related QoS metrics. Also We have compared with subjective quality assessment by expert group to verify validity of our objective quality assessment scheme using the user-related QoE metrics.
