Super Multi-View (SMV) video is a key enabler for future 3D video services that allows a glasses-free visualization and eliminates many causes of discomfort existing in current available 3D video technologies. SMV video content is composed of tens or hundreds of views, that can be aligned in horizontal only or both horizontal and vertical directions, providing respectively horizontal parallax or full parallax. This paper compares several coding schemes and coding orders, and proposes a coding structure that exploits inter-view correlations in the two directions, providing BD-rate gains up to 29.1% when compared to a basic anchor structure. Additionally, Neighboring Block Disparity Vector (NBDV) and Inter-View Motion Prediction (IVMP) coding tools are further improved to efficiently exploit coding structures in two dimensions, with BD-rate gains up to 4.2% reported over the reference 3D-HEVC encoder.
