Paper Abstract

We present a novel analysis of encoding latency for arbitrary multiview video coding prediction structures. This analysis allows us to compare the efficiency of multiview prediction structures beyond rate-distortion performance, i.e., it makes it possible to select those structures that are more amenable to low latency encoding. As a result, we have developed a general framework (models and tools) for the characterization of latency that can be used for arbitrary dependency structures. Finally, we have focused on the JMVM prediction structure with the aim of deriving new structures with similar rate distortion performance and lower latency. Experimental results help us illustrate the importance of taking into consideration encoding latency when selecting a prediction structure.
