A quality scalable extension design is proposed for the upcoming 3D video on the emerging standard for High Efficiency Video Coding (HEVC). A novel interlayer simplified depth coding (SDC) prediction tool is added to reduce the amount of bits for depth maps representation by exploiting the correlation between coding layers. To further improve the coding performance, the coded prediction quadtree and texture data from corresponding SDC-coded blocks in the base layer can be used in interlayer simplified depth coding. In the proposed design, the multiloop decoder solution is also extended into the proposed scalable scenario for texture views and depth maps, and will be achieved by the interlayer texture prediction method. The experimental results indicate that the average Bjøntegaard Delta bitrate decrease of 54.4% can be gained in interlayer simplified depth coding prediction tool on multiloop decoder solution compared with simulcast. Consequently, significant rate savings confirm that the proposed method achieves better performance.
针对即将到来的基于高效视频编码（HEVC）新兴标准的3D视频，提出了一种高质量的可扩展扩展设计。添加了一种新颖的层间简化深度编码（SDC）预测工具，通过利用编码层之间的相关性来减少深度图表示的比特数。为了进一步提高编码性能，来自基础层中相应SDC编码块的编码预测四叉树和纹理数据可用于层间简化深度编码。在所提出的设计中，多环解码器解决方案也扩展到了针对纹理视图和深度图的所提出的可扩展场景中，并将通过层间纹理预测方法来实现。实验结果表明，与联播相比，在多环解码器解决方案的层间简化深度编码预测工具中，平均Bjøntegaard Delta比特率可降低54.4%。因此，显著的码率节省证实了所提出的方法具有更好的性能。
