Abstract

In this paper, we research the IPTV that is the convergence technique of TV and network technique and performed the performance evaluation of picture quality of IPTV in the situation of increasing the network traffic in the Internet environment. To do this, we constructed the mock Internet network similar to the real Internet environment and measured the quality of received video using V-Factor model according to the increase of network traffic, and analyzed the result of the experiment. Making use of the result of this paper for the threshold value of V-Factor, the measured factor of network performance, the measured factor of video performance in the watchable IPTV video quality.

본 논문에서는 네트워크와 TV기술의 융합분야인 IPTV에 관한 연구로써 인터넷 환경에서 망의 트래픽증가에 따른 IPTV의 영상품질의 성능평가를 수행하였다. 이를 위해 실제 인터넷망과 유사한 모의 인터넷망을 구축하여 트래픽증가에 따른 IPTV의 수신 영상의 품질을 V-Factor 측정모델을 사용하여 실험하였으며, 그 결과를 분석하였다. 본 논문에서 도출한 결과는 IPTV 방송에서 시청 가능한 화질의 V-Factor, 네트워크 성능 측정요소, 콘텐츠 관련 측정요소 등에 대한 임계치의 기준으로 활용할 수 있을 것으로 판단된다.
