摘要

本文针对下一代视频编码标准，包括通用视频编码(VVC)和中国音视频标准3 (AVS3)，提出了一种IBC-Mirror模式的屏幕内容编码(SCC)。这是VVC/AVS3中首次考虑到SCC的镜像特性。在Intra Block Copy (IBC)模式的平移运动模型的基础上，进一步增加了“水平和垂直翻转”功能，以减少预测误差，提高编码效率。IBC-Mirror模式是在最新的参考软件VTM5.0 (VVC)和HPM-5.0 (AVS3)上实现的。仿真结果表明，该方法对SCC测试序列可分别节省1~2% (VVC)和4~7% (AVS3)的bd速率。该模型的草案已提交给AVS会议，并在SCC核心实验(CE)中进行了研究。

IBC-Mirror Mode for Screen Content Coding for the Next Generation Video Coding Standards

This paper proposes an IBC-Mirror mode for Screen Content Coding (SCC) for the next generation video coding standards, including Versatile Video Coding (VVC) and Audio Video Standard-3 in China (AVS3). It is the first time to take mirror characteristic into consideration for SCC in VVC/AVS3. Based on the translational motion model of Intra Block Copy (IBC) mode, the function of "horizontal and vertical flipping" is further added to reduce prediction error and improve coding efficiency. The proposed IBC-Mirror mode is implemented on the latest reference software, including VTM5.0 (VVC) and HPM-5.0 (AVS3). The simulations show that the proposed mode can achieve up to 1~2% (VVC) and 4~7% (AVS3) BD-rate saving for SCC test sequences. Drafts about the mode have been submitted to AVS meeting and investigated in SCC Core Experiments (CE).
