High Efficiency Video Coding (HEVC) is actually the latest video standard that enables significant compression performance improvement in comparison with its predecessors. Scalable High Efficiency Video Coding (SHVC) and 3D High-Efficiency Video Coding (3D-HEVC) are extensions of HEVC hooked on recently emerged applications and issues. 3D-HEVC targets the monolayer compression of the specific multiview plus depth 3D video representation. It consists of multiple views and their associated depth maps that are required for synthesizing intermediate views in advanced free viewpoint applications. SHVC combines the compression efficiency and visual quality of HEVC, with the possibility of encoding different versions of a same video in a single bitstream. It is conceived to cope with the heterogeneity of networks and devices used in the transmission chain of texture videos. With the ongoing progess in equipments and technologies, the scalable multilayer coding is also solicited, not to say required, for depth maps. In comparison with 3D-HEVC, this paper shows how SHVC works for quality scalable depth maps compression over different base and enhancement layers quantization scenarios. Besides, this paper analyzes the SHVC efficiency for intermediate views that are synthesized from encoded depth maps. Thus we aim to provide support for upcoming works on depth map quality scalable encoding.

高效视频编码（HEVC）实际上是最新的视频标准，与之前的版本相比，它可以显着提高压缩性能。可扩展的高效视频编码（SHVC）和3D高效视频编码（3D-HEVC）是HEVC的扩展，与最近出现的应用程序和问题挂钩。3D-HEVC的目标是特定多视图加深度3D视频表示的单层压缩。它由多个视图及其关联的深度图组成，这些视图是高级自由视点应用程序中合成中间视图所需的。SHVC结合了HEVC的压缩效率和视觉质量，并可以在单个比特流中编码同一视频的不同版本。它被设计来应对纹理视频传输链中使用的网络和设备的异构性。随着设备和技术的不断进步，对于深度图也征求了可伸缩的多层编码，尽管不是必需的。与3D-HEVC相比，本文显示了SHVC如何在不同基础层和增强层量化方案上实现质量可伸缩深度图压缩。此外，本文还分析了从编码深度图合成的中间视图的SHVC效率。因此，我们旨在为深度图质量可伸缩编码的即将开展的工作提供支持。本文展示了SHVC如何在不同的基础层和增强层量化方案上实现质量可伸缩的深度图压缩。此外，本文还分析了从编码深度图合成的中间视图的SHVC效率。因此，我们旨在为深度图质量可伸缩编码的即将开展的工作提供支持。本文展示了SHVC如何在不同的基础层和增强层量化方案上实现质量可伸缩的深度图压缩。此外，本文还分析了从编码深度图合成的中间视图的SHVC效率。因此，我们旨在为深度图质量可伸缩编码的即将开展的工作提供支持。
