A novel architecture for parallel multi-view HEVC decoder on mobile device

Abstract: The multi-view HEVC (MV-HEVC) extension was finalized in July of 2014 by the Moving Picture Experts Group and the Video Coding Experts Group. Recently, multi-view videos based on stereo representations are becoming widely popular. Also, a variety of multimedia contents are now available for mobile devices. A real-time multi-view video decoder is therefore needed. In mobile devices, a real-time decoding multi-view video is difficult because of the increasing number of views, spatial resolutions, and limited spe… Show more

“…The improved acceleration algorithm combines the changes in the characteristics of the movement of the crowd and the changes in the distribution of the population. The algorithm's detection results are accurate under different block sizes [9] The neighborhood size for solving the acceleration in the experiment was 5 × 5; (3) regarding anomaly classification, most algorithms are based on empirical thresholds. The threshold ε in this paper is mainly the continuous actual detection and analysis of different datasets; and (4) an optimal behavior determination based on an optimal threshold is applied to a given video sequence.…”

“…This method was able to minimize the decoding time by 30% compared to the sequential method. Other embedded implementation of HEVC decoder that applies a parallel optimized method was reported by Liu et al [14] for the multi-view video decoding using the multi-threading. The results show that the proposed method is 5 times faster in the ARM platforms.…”

“…Stage 3: Filtering, which corresponds to transitions (15,16,17,18,19,20,21,22,23,24,25,26). This stage corresponds to the Loop Filter process A parametric analysis of the application has enabled to deduce that the overall execution time of Stages 0, 1 and 3 is approximately equivalent to the execution time of Stage 2.…”
