The paper presents a new approach to multiview video coding using Screen Content Coding. It is assumed that for a time instant the frames corresponding to all views are packed into a single frame, i.e. the frame-compatible approach to multiview coding is applied. For such coding scenario, the paper demonstrates that Screen Content Coding can be efficiently used for multiview video coding. Two approaches are considered: the first using standard HEVC Screen Content Coding, and the second using Advanced Screen Content Coding. The latter is the original proposal of the authors that exploits quarter-pel motion vectors and other nonstandard extensions of HEVC Screen Content Coding. The experimental results demonstrate that multiview video coding even using standard HEVC Screen Content Coding is much more efficient than simulcast HEVC coding. The proposed Advanced Screen Content Coding provides virtually the same coding efficiency as MV-HEVC, which is the state-of-the-art multiview video compression technique. The authors suggest that Advanced Screen Content Coding can be efficiently used within the new Versatile Video Coding (VVC) technology. Nevertheless a reference multiview extension of VVC does not exist yet, therefore, for VVC-based coding, the experimental comparisons are left for future work.

使用高级 HEVC 屏幕内容编码的多视图视频压缩

本文提出了一种使用屏幕内容编码进行多视图视频编码的新方法。假设在某个时刻，对应于所有视图的帧被打包成单个帧，即应用多视图编码的帧兼容方法。对于这种编码场景，本文展示了屏幕内容编码可以有效地用于多视图视频编码。考虑了两种方法：第一种使用标准 HEVC 屏幕内容编码，第二种使用高级屏幕内容编码。后者是作者的原始提议，它利用了 HEVC 屏幕内容编码的四分之一像素运动矢量和其他非标准扩展。实验结果表明，即使使用标准 HEVC 屏幕内容编码，多视图视频编码也比联播 HEVC 编码高效得多。提议的高级屏幕内容编码提供与 MV-HEVC 几乎相同的编码效率，这是最先进的多视图视频压缩技术。作者建议可以在新的多功能视频编码 (VVC) 技术中有效地使用高级屏幕内容编码。然而，VVC 的参考多视图扩展尚不存在，因此，对于基于 VVC 的编码，实验比较留待未来工作。
