Abstract Thus far, Multiview High-Efficiency Video Coding (MV-HEVC) can only use a central processing unit (CPU) to perform decompression on a personal computer (PC) or workstation. Because MV-HEVC is much more complex than High-Efficiency Video Coding (HEVC), decompressors need higher parallelism to decompress in real time. Therefore, this study presents a parallel method based on MV-HEVC. Inter-view complete parallelism is realized according to the dependent relationship between other MV-HEVC views, and a search range is not required to avoid the data dependence between frames. Based on the dependencies of each task in MV-HEVC, an advanced wavefront parallel processing method is proposed to achieve higher intra-frame parallelism. The parallel structure of the proposed method is compatible with that of the single-instruction multiple-data acceleration method. The results showed that the proposed method can decompress MV-HEVC with 20 threads in real time for 1088p video with three views.
