摘要

多视图视频编码(MVC)方案的性能是未来实现中需要考虑的最重要的方面。关于编码效率和预测结构之间的关系，已经做了大量的研究。然而，MVC的结构对用户和视频服务器之间的交互影响很大，这是评估MVC方案除PSNR之外的重要因素。基于图论定义了视图依赖关系(View dependency, VD)，分析了MVC模式的传输效率。采用三个定义和参数来评价MVC结构的交互和传输性能。实验结果表明，在对视频序列进行编码后，VD可以作为预测器来估计MVC方案相应的传输带宽。

Analysis on Transmission Performance for Multiview Video Coding Schemes

The performance of multiview video coding (MVC) scheme is the most important aspect to be considered in future implementations. Many works have been done on the discussions between encoding efficiency and prediction structures. However, the structure of MVC can greatly affect interaction between user and video server, which is important to evaluate MVC scheme besides PSNR. View dependency (VD) is defined based on graph theory to analyze transmission efficiency of MVC scheme. Three definitions and parameters are used to evaluate the performance on interaction and transmission of MVC structures. Experimental results show that VD can be used as a predictor to estimate corresponding transmission band-width for MVC scheme after video sequences are encoded it.
