Abstract

In this paper, we proposed the qualify metric based on SVC and the subjective quality. The proposed quality metric is for a general purpose. It means we can use it for any video sequences regardless of its temporal and spatial characteristics. The Quality of Service(QoS) is one of the important issues in heterogeneous environment which has diverse restrictions such as limited network bandwidth and limited display resolution. Scalable Video Coding(SVC) is the efficient video coding skill in heterogeneous environment. Because SVC can be adapted to various quality bitstreams using three scalabilities(spatial, temporal, and SNR) from one bitstream which has full scalability. To maximize the QoS in this environment, we should consider the subjective quality which is the viewer response. And also we should consider temporal and spatial characteristics of video sequence because the subjective quality is affected by temporal and spatial characteristics of video sequence. To verify the efficiency of the proposed method, we perform subjective assessments. The experimental results show that the proposed method has high correlation with subjective quality. The proposed method can be a decision tool of SVC birstream extraction.

본 논문에서는 영상 특성에 제약 없이 적용 가능한 SVC 기반 범용 품질 메트릭을 제안한다. 이종 환경에서의 비디오 콘텐츠 소비가 증가하면서 서비스 품질(Quality of Service, QoS)은 중요한 이슈 중 하나가 되었다. 또한 스케일러블 비디오 코딩(Scalable Video Coding, SVC)은 하나의 부호화된 비트스트림이 공간적, 시간적 그리고 품질적으로 다양한 확장이 가능하다는 장점을 이유로 이종 환경에서 적응성이 높은 영상 부호화 기술로 주목받고 있다. 제한된 환경에서의 서비스 품질 보장을 위해서는 서비스의 사용 주체인 사람이 느끼는 주관적 비디오 품질이 고려되어야 한다. 주관적 품질은 영상의 시간적, 공간적 특성 모두에 영향을 받기 때문에 영상의 특성에 대한 고려 역시 중요하다. 제안하는 방법의 효율성은 실험을 통해 측정된 주관적 품질 값과 제안된 품질 메트릭을 이용해 측정된 품질 지수 사이의 상관계수를 이용하여 검증하였으며 제안하는 품질 메트릭은 SVC의 품질 확장 결정 기준으로 사용될 수 있다.
