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.
