EN The paper presents an extension of 3D-HEVC for the circular camera arrangements. It generalizes the derivation of the disparity vectors from depth data for sequences captured using cameras located on an arc. The general equation for disparity calculations has been implemented instead of the simplified equation used in 3D-HEVC. Experiments have been performed on widely recognized multiview test sequences with both circular and linear camera arrangements. In the case of sequences obtained using cameras located on an arc, the proposed extension provides about 6% bitrate reduction when compared to 3D HEVC, and does not influence the 3D-HEVC performance for linear view arranged sequences.
