H.264/AVC 표준은 손실이 많은 패킷 네트워크를 통해 압축된 비디오 신호를 안정적으로 전송할 수 있도록 몇 가지 새로운 오류 복원 기능을 제공합니다. FMO(Flexible Macroblock Ordering)는 H.264/AVC 표준 내에서 가장 흥미로운 탄력성 기능 중 하나입니다. 연속적인 래스터 스캔 매크로블록으로 슬라이스를 구성했던 이전 표준과 달리 FMO는 공간적으로 분산된 매크로블록(MB)으로 구성되고 혼합 방식으로 구성된 새로운 슬라이스를 제안합니다. H.264/AVC는 6가지 유형의 FMO를 지정합니다. 또한 표준은 프레임 내의 각 MB를 사용 가능한 슬라이스 그룹에 명시적으로 할당할 수 있는 명시적인 FMO 유형(유형 264)을 정의합니다. 따라서 표준을 위반하지 않고 새로운 FMO 유형을 사용하고 HXNUMX/AVC에 통합할 수 있습니다. 본 논문에서는 다른 모든 FMO 유형보다 성능이 뛰어난 새로운 ECW(Explicit Chessboard-Wipe) FMO(Flexible Macroblocks Ordering) 기술을 제안합니다. 새로운 ECW 순서 지정으로 인해 손상된 매크로블록 주변에 있는 올바르게 수신된 매크로블록의 수를 최대화하는 효과적인 오류 분산이 발생하여 더 나은 오류 은폐가 가능해졌습니다. 성능 평가는 제안된 명시적 FMO 접근 방식이 모든 FMO 유형보다 성능이 우수하다는 것을 보여줍니다. 제안된 접근법을 검증하기 위해 주관적 및 객관적인 시각적 품질 비교 연구도 수행되었습니다.

Abstract: The H.264/AVC standard provides several new error-resilient features to enable the reliable transmission of compressed video signals over lossy packet networks. Flexible Macroblock Ordering (FMO) is one of the most interesting resilient features within the H.264/AVC standard. Unlike former standards, in which slices were constructed out of consecutive raster scan macroblocks, FMO suggests new slices composed of spatially distributed Macroblocks (MBs), and organized in a mixed-up fashion. H.264/AVC specifies seven types of FMO. The standard defines also an explicit FMO type (Type 6), which allows explicitly assignment of each MB within the frame to any available slice groups. Therefore new FMO types can be used and integrated into H264/AVC without violating the standard. In this paper we propose a new Explicit Chessboard-Wipe (ECW) Flexible Macroblocks Ordering (FMO) technique, which outperforms all other FMO types. The new ECW ordering results in effective error scattering which maximizes the number of correctly received macroblocks located around corrupted macroblocks, leading to better error concealment. Performance evaluations demonstrate that the proposed Explicit FMO approach outperforms all the FMO types. Both subjective and objective visual quality comparative study has been also carried out in order to validate the proposed approach.
