dc.description.abstract-translatedOne of the most popular data formats to represent natural immersive visual data is the MVD (Multiview Video plus Depth) format. The representation of a three-dimensional scene requires a huge amount of data in the form of a dense set of views accompanied by high-quality depth maps. All of this data need to be transmitted over the network to a viewer. Therefore, a question arises, how to allocate the bitrate between views and depth maps to obtain the maximal quality for a given bit budget. In the paper, a simple model for optimum bitrate allocation between color and depth data in 3D-HEVC coding is proposed. The provided model for quantization parameters allows better bitrate division between color and depth data, which leads to a significant (23-35%) bitrate reduction of the total bitrate of the multiview stream. At the same time, it preserves the same quality of synthesized virtual views in comparison to the common test condition (CTC) recommendation, which is considered as a wellestablished reference encoder configuration.en
