본 논문에서는 고품질-DMB(Advanced Terrestrial-DMB) 비디오 서비스를 제공하기 위해 SVC (Scalable Video Coding) 부호화기법을 다룬다. SVC 기저계층으로 T-DMB 서비스와 호환이 되도록 하면서, 향상계층은 공간 확장성을 통하여 AT-DMB 비디오 서비스를 제공할 수 있다. 그러나 SVC 부호화 기법은 매우 복잡하므로, 이를 구현하기 위해서는 SVC 부호화기의 복잡도에 따른 성능 분석이 필요하다. 본 논문에서는 SVC 부호화 파라미터에 따른 성능 변화를 조사하고, 이를 기반으로 3가지 부호화기 모델에 따른 복잡도 및 성능 특성을 모의실험을 통하여 비교 분석한다.
