论文摘要
2020年7月，ITU-T和ISO/IEC的联合视频专家团队（JVET）完成了Vertatile视频编码标准（H.266/VVC）。这款新的ITU推荐/国际标准是著名H.265/HEVC视频编码标准的继任者，具有大约增强的压缩效率，但具有增强的计算效率，但计算成本高度计算。本文研究了H.266/VVC解码器处理模块的复杂性。提出了使用SIMD指令扩展程序和其他并行处理（包括数据和任务级别并行性）的优化解码器实现，可以在基于X86的CPU上实现4K 60FPS VVC BITSTREAMS的实时解码。
Versatile Video Coding Standard (H.266/VVC) was completed by Joint Video Expert Team (JVET) of ITU-T and ISO/IEC, in July 2020. This new ITU recommendation/international standard is a successor to the well-known H.265/HEVC video coding standard with roughly doubled compression efficiency, but also at the cost of an increased computational complexity. The complexity of H.266/VVC decoder processing modules is studied in this paper. An optimized decoder implementation using SIMD instruction extensions and additional parallel processing including data and task level parallelism is presented, which can achieve real-time decoding of 4K 60fps VVC bitstreams on an x86 based CPU.
