Abstract

IPTV 멀티캐스팅 서비스에서 증가되는 네트워크 트래픽 로드에 따른 화상 품질 측정과 화상 품질 변화에 대한 연구는 IPTV 서비스에 대한 관심이 현실화됨에 따라 필요하게 되었다. 본 연구에서는 네트워크 트래픽 로드에 따른 화상 품질의 효과가 주어지는 네트워크 성능 요소의 최적의 값을 파악하기 위하여, 테스트 베드 네트워크를 통하여 테스트 하는 S/W를 개발하였다. 그리고 테스트 환경을 학교 네트워크로 확장하여 실제 IPTV 서비스 환경과 비슷한 학교 네트워크에서 네트워크 트래픽 로드 증가에 따른 IPTV 멀티캐스팅 서비스의 화상 품질 변화를 측정하고자 하였다. The research of image quality estimation standard and the image quality change according to the network traffic load increase at IPTV multicasting service is necessary because the concern of IPTV(Internet Protocol TV) service become active recently. In the research, for finding out the threshold value of network performance elements giving the effect to the image quality according to the network traffic load, we developed S/W to operate the test bed network and make the test scenario through test bed network test and then we expand the test environment scope to the college network and try to measure the image quality change of IPTV multicasting service according to the network traffic load increase at the college network similar to the real IPTV service environment.
