This paper presents coding schemes for multiple color and depth video using a hierarchical representation. We use the concept of layered depth image (LDI) to represent and process multiview video with depth. After converting those data to the proposed representation, we encode color, depth, and auxiliary data representing the hierarchical structure, respectively. Two kinds of preprocessing approaches are proposed for multiple color and depth components. In order to compress auxiliary data, we have employed a near lossless coding method. Finally, we have reconstructed the original viewpoints successfully from the decoded LDI frames. From our experiments, we realize that the proposed approach is useful for dealing with multiple color and depth data simultaneously.
