Abstract: An apparatus for transmitting a video comprises an inter-view redundancy remover configured to remove redundant information of pictures for viewing positions, where redundant pixel information between the pictures in adjacent viewing positions is removed, a packing unit configured to pack the pictures and generate packing information, and an encoder configured to encode the pictures. The apparatus is further configured to perform multi-view packing the pictures into a packed picture, where each view for the picture includes different types of a texture and a depth map, and a residual of texture and a depth map are generated for a subsidiary view based on redundancy between each view. The apparatus is further configured to generate signaling information for the inter-view redundancy remover, the packing unit, or the multi-view packing.
