Abstract.  As any existing video codec, multiview video coding requires a highly efficient compression as well as a faster random access to any given view. Such efficiency for the coding approach can be achieved by exploiting both the temporal and the inter-view correlation. The temporal and view random access are improved by the increase of intracoded pictures (I pictures), which requires more bit rate. In this research study, we propose and evaluate an improved inter-view prediction structure mainly based on reducing the complexity of view random access at any instance Tn and improving the inter-view correlation for P-view. These improvements can be guaranteed by the appropriate choice of the position of I-view, the type of the different views, and the number of each frame type to use. Compared to the prediction scheme, which is based on the hierarchical B pictures structure and used for joint multiview video model, experimental results have shown that the proposed prediction structure provides better bit-rate performance of up to 6.81% with a similar compression quality measured in peak signal-to-noise ratio and significantly improves view random access by up to 25%.
