%X The temporal and inter-view correlation of multi-view videos (MVV)changes not only from sequence to sequence but also from frame to frame. Therefore, the fixed prediction structure of the Joint Multi-View Video Coding (JMVC)has difficulties coping with various characteristics of different MVV sequences. In this paper, a flexible prediction structure for multi-view video coding (FPS_MVC)is proposed based on the analysis of the hierarchical B picture prediction structure and the temporal correlation and inter-view correlation between the current frame and its references.Its temporal level (TL)and the temporal and inter-view correlation of the MVV sequence decide whether the inter-view prediction of the current encoded frame is adopted. Experimental results show that the proposed FPS_MVC outperforms Scalable Prediction Structure (SPS_MVC)on reducing computation complexity, improving random access (RA)ability, and decreasing the decode picture buffer (DPB)size by about 45%, 28%, and 46% on average, while maintaining almost the same coding efficiency.
