Multi-view video (MVV) representation based on depth data, such as multi-view video plus depth (MVD), is emerging a new type of 3D video communication services. In the meantime, the problem of coding and transmitting the depth video is being raised in addition to classical texture video. Depth video is considered as key side information in novel view synthesis within MVV systems, such as three-dimensional television (3D-TV) or free viewpoint television (FTV). Nonetheless the influence of depth compression on the novel synthesized view is still a contentious issue. In this chapter, we propose to discuss and investigate the impact of the wavelet-based compression of the depth video on the quality of the view synthesis. After the analysis, different frameworks are presented to reduce the disturbing depth compression effects on the novel synthesized view.
