In 3DTV system, virtual view generation can be accomplished by depth image-based rendering (DIBR) system. And, depth map is key side information for generating virtual image by using DIBR technique in 3DTV system. Before compressing, depth map need to be quantified. But, which quantification method should be choose or how to transform depth information is still a contentious issue. In this paper, we compare the effect of two depth map quantification methods for coding and synthesizing. By the experiments, we show that the depth map is coded efficiently in terms of the bit rate and quality of the synthesized image when it uses uniform quantization method.
