Zusammenfassung:	The present invention relates to a method for modeling image quality of real-time experience based on GOP information. The method for modeling image quality of real-time experience based on GOP information according to the present invention comprises the steps of: identifying the number of packets constituting a frame; identifying the average number of packets per frame of GOP including the frame; calculating a distortion value at a single frame when a single packet of the frame is lost; and calculating a distortion value at a single frame located at a predetermined distance when a single packet of the frame is lost. 제안하는 GOP 정보 기반의 실시간 체감형 영상 품질 모델링 방법이 제시된다. 본 발명에서 제안하는 GOP 정보 기반의 실시간 체감형 영상 품질 모델링 방법은 프레임을 구성하는 패킷 수를 확인하는 단계, 상기 프레임을 포함하는 GOP의 프레임 당 평균 패킷 수를 확인하는 단계, 상기 프레임의 단일 패킷 손실 시 단일 프레임에서의 왜곡 값을 계산하는 단계 및 상기 프레임의 단일 패킷 손실 시 미리 정해진 거리만큼 떨어진 단일 프레임에서의 왜곡 값을 계산하는 단계를 포함할 수 있다.
