초록

네트워크 및 전송기술의 발달로 통신망을 이용하여 IPTV와 같은 서비스를 제공하는 것이 가능하게 되었다. IPTV는 기존 방송과 달리 IP 망을 통해 데이터의 송수신이 이루어지므로, 전송에러가 발생할 수 있으며, 이 경우 패킷의 손실 및 지연 등의 이유로 열화가 발생하게 된다. 이러한 열화는 사용자의 체감품질에 영향을 미쳐 IPTV서비스에 대한 사용자의 신뢰도를 저하 시킨다. 본 논문에서는 IPTV서비스에서 체감 품질 보장 및 품질 모니터링에 관한 IPTV국제 표준화 동향 및 규정을 소개하고, IPTV 사용자의 체감품질을 보장하기 위한 방법을 고찰한다.
