초록

본 논문에서는 SVC와 MVC의 부호화 구조를 결합하여 구현된 스케일러블 다시점 비디오 부호화를 위한 효율적인 움직임 추정 기법과 DPB 설계 메카니즘에 대해 제안한다. 제안된 움직임 추정 기법에서는 부호화 과정에서 필요한 예측 부호화의 성능 향상을 위해서 서로 다른 시점 (view)의 픽처 정보를 참조픽처의 후보로서 활용한다. 제안된 움직임 예측 구조에 의해서 압축된 비디오 데이터의 크기를 감소시켜 압축 효율을 증대시킬 수 있다. 또한, 스케일러블 다시점 비디오 부호화를 수행할 때 SVC와 MVC의 DPB (Decoded Picture Buffer)를 통합한 통합형 DPB 설계 메카니즘에 대해 제안한다. 다양한 실험을 통해서 제안된 예측 구조를 적용함으로써 스케일러블 다시점 비디오 부호화에서의 압축 효율의 향상을 얻어낼 수 있음을 확인하였다.

In this paper, we propose an efficient motion prediction architecture and DPB design mechanism for scalable multi-view video coding which is implemented by integrating SVC and MVC coding algorithms. In the proposed motion prediction architecture, we employ pictures associated with other views as a candidate for reference picture for improved motion prediction performance. By the proposed prediction architecture, we could enormously reduce the size of compressed video data. When performing scalable multi-view video coding, an integrated DPB design mechanism is also proposed. It is shown by various simulations that the proposed motion prediction architecture for scalable multi-view video coding can result in reduced data size in the compressed bitstream.
