Abstract

Multiview video coding (MVC) plays an important role in three-dimensional audio-video (3DAV) systems. Multiview video display systems are built to provide interactive video services and quality of services (QoS) provided by the system is currently under consideration. MVC encoder uses advanced coding schemes and group of GOP (GoGOP) structure to pursue high compressibility. There is a conflict between compressibility and access ability, i.e., QoS of interaction. In this paper, several evaluation functions are proposed to measure the load and access ability of multiview video system. A nonlinear multipurpose mathematical model based on these functions is provided for interaction analysis. On considering the model, the access ability is a factor to be taken into account for encoder when high compressibility is the primary, and so is the compressibility when trying to achieve high access ability.
