随着自动立体显示器的出现，关于如何有效地压缩这种显示器所需的视频信息的问题出现了。此外，为了逐渐被市场接受这项新技术，有一种解决方案提供与目前使用的立体3D视频的前向兼容性是很有价值的。利用高效视频编码(HEVC)中高效的单视图编码工具，提出了一种多视点压缩方案。虽然使用HEVC可以获得有效的单视图压缩，但该标准的多视点适配正在开发中，提供了额外的编码收益。平均而言，对于纹理信息，总码率可以比联播HEVC降低37.2%。对于深度图压缩，增益在很大程度上取决于捕获内容的质量。此外，还提出了前向兼容的解决方案，提供了从基于H.264/AVC的立体3D系统逐步升级到基于HEVC的自动立体环境的可能性。与多视点视频编码(MVC)相比，该系统具有显著的码率节省。
With the advent of autostereoscopic displays, questions rise on how to efficiently compress the video information needed by such displays. Additionally, for gradual market acceptance of this new technology it is valuable to have a solution offering forward compatibility with stereo 3D video as it is used nowadays. In this paper, a multiview compression scheme making use of the efficient single-view coding tools used in High Efficiency Video Coding (HEVC) is provided. Although efficient single view compression can be obtained with HEVC, a multiview adaptation of this standard under development is proposed, offering additional coding gains. On average, for the texture information, the total bitrate can be reduced by 37.2% compared to simulcast HEVC. For depth map compression, gains largely depend on the quality of the captured content. Additionally, a forward compatible solution is proposed offering the possibility for a gradual upgrade from H.264/AVC based stereoscopic 3D systems to an HEVC-based autostereoscopic environment. With the proposed system, significant rate savings compared to Multiview Video Coding (MVC) are presented.
