随着3D视频技术的发展，对压缩效率和率失真性能的研究越来越多。当3D视频在容易出错的通道上传输时，它们的质量可能会显著下降。本文将多视点视频编码(MVC)和多描述编码(MDC)相结合，以实现稳健传输。该算法能够充分考虑视点内和视点间的相关性，以获得更好的估计效果。此外，还设计了一种自适应模式判决来生成作为冗余信息的标签。实验表明，该算法的冗余信息仅占用几个比特，而重建视频的峰值信噪比有明显的提高。
With the development of 3D video technology, many studies have paid attention to compression efficiency and rate distortion performance. When 3D videos are transmitted over error-prone channels, they may suffer significant quality degradation. In this paper, we combine multiview video coding (MVC) with multiple description coding (MDC) for robust transmission. The proposed scheme can give full consideration of both intra-view and inter-view correlation for better estimation. Furthermore, an adaptive mode decision is designed to generate a label as redundant information. The experiments show that the redundant information occupies just a few bits while the PSNR values of the reconstructed videos demonstrate a significant improvement.
