摘要

本文分析了JVET编码器的复杂性。JVET是ITU-T VCEG和ISO/IEC MPEG的联合视频探索小组，旨在探索视频编码的新方法，以提高HEVC/H。265标准。目前，JVET参考软件JEM 7的压缩能力比HEVC参考软件HM提高了30%，但其计算复杂度明显高于HM。通过分析函数调用，可以分析和报告不同编码场景下耗时的函数。据观察，如果不考虑优化，即将到来的标准可能会使当前HEVC标准的复杂性增加多达20倍。详细分析了各功能的贡献。其复杂性主要归功于新的内编码函数和新的变换编码。

JVET Encoder Complexity Analysis

In this paper the complexity of the JVET encoder is analyzed. JVET is the joint video exploration team of ITU-T VCEG and ISO/IEC MPEG to explore new ways in video coding to improve HEVC/H.265 standard. Currently, JEM 7, the JVET reference software, is able to compress 30% better than HM, the HEVC reference software but its computational complexity is considerably higher than HM. By profiling function calls, time consuming functions in different encoding scenarios are analyzed and reported. It is observed that the upcoming standard could increase the complexity by up to 20 times compared to the current HEVC standard, if no optimization is considered. The contribution of each function is detailed and analyzed. The complexity is mostly attributed to the new intra-coding functions and new transform coding.
