| 摘 要： | 新一代视频编码标准HEVC(High Efficiency Video Coding)主要面向高清及超高清视频编码,压缩效率相比之前的编码标准H.264有较大提高.但压缩效率的提高必然会带来计算的复杂化,为提高HEVC的解码效率,降低时延,提出了一种并行解码器架构.该并行解码器的设计是基于HEVC中熵片(Entropy slice)和波前并行处理(Wavefront Parallel Processing, WPP)技术的引入以及滤波器(Deblocking Filter)无相关性的特点.实验结果表明,该并行解码器能够充分利用硬件资源,提高解码效率.

| Abstract: | HEVC(High Efficiency Video Coding) is the latest video coding standard. It aims at the high definition video and the ultra high definition video and its compression efficiency increased significantly compared with H.264 .But the increase of the compression efficiency can result in more complex operation. To increase the decoding efficiency, a parallel optimization algorithm is proposed in this paper. The parallel architecture is based on the entropy slice ,WPP and dependent data of deblocking filter in HEVC.The experimental result indicates that the parallel HEVC decoder can increase the decoding efficiency significantly. |
