论文摘要
Open Media联盟最近启动了编码工具探索活动，以超越AV1的下一代视频编码。在这方面，本文介绍了一套编码工具包，这些工具已在代码库（称为Libaom）之上进行了研究，实施和测试，该工具用于探索下一代视频压缩工具。提出的工具涵盖了基于传统混合视频编码结构的几个技术领域，包括块分区，预测，转换和循环过滤。提出的编码工具被整合为包装，并在本文中展示了与AV1相比的组合编码增益。此外，为了更好地了解每个工具的行为，除了组合编码增益外，还为每个单独的编码工具进行了模拟和工具关闭测试。实验结果表明，与LIBAOM相比，所提出的方法平均达到8.0％（高达22.0％）的总体BD率降低，用于所有内部编码配置，多种图像和视频内容。
The Alliance for Open Media has recently initiated coding tool exploration activities towards the next-generation video coding beyond AV1. With this regard, this paper presents a package of coding tools that have been investigated, implemented and tested on top of the codebase, known as libaom, which is used for the exploration of next-generation video compression tools. The proposed tools cover several technical areas based on a traditional hybrid video coding structure, including block partitioning, prediction, transform and loop filtering. The proposed coding tools are integrated as a package, and a combined coding gain over AV1 is demonstrated in this paper. Furthermore, to better understand the behavior of each tool, besides the combined coding gain, the tool-on and tool-off tests are also simulated and reported for each individual coding tool. Experimental results show that, compared to libaom, the proposed methods achieve an average 8.0% (up to 22.0%) overall BD-rate reduction for All Intra coding configuration a wide range of image and video content.
