Robust multi-view video transmission over errorprone networks is a technical challenge problem for multi-view video coding (MVC). In this paper, a frame loss error concealment scheme is proposed for MVC to address the challenging problem at the decoder side. Different from traditional motion information derivation in temporal domain for single-view video coding, two novel information derivation schemes, motion information derivation in inter-view domain and disparity information derivation in temporal domain, are proposed in this paper. Each block of lost frames can be reconstructed from its temporal reference frame and its interview reference frame by merging different concealment results under the three prediction information derivations. Simulation results show that the proposed scheme can improve frame loss error concealment performance for MVC. Keywords-Multi-view video coding; frame loss error concealment; information derivationI.

Summary In the Three‐Dimensional Multi‐View Video (3D MVV) coding prediction structure, the coded bit‐streams may be dropped down due to error transmissions. So, it is compulsory to recover the corrupted Macro‐Blocks (MBs) at the decoder utilizing efficient Error Concealment (EC) post‐processing techniques. The EC methods exploit the temporal, inter‐view, and spatial matching among 3D MVV views and frames without any alterations in the encoder software or hardware or in the transmission rate. They retrieve the Disparity Vectors (DVs) and Motion Vectors (MVs) of the erroneous MBs. To enhance the received 3D MVV quality, we suggest several optimized schemes to reconstruct the lost and erroneous MBs of inter‐encoded and intra‐encoded frames. A hybrid method combining the Circular Scan Order Interpolation Algorithm (CSOIA) and Partitioning Motion Compensation Algorithm (PMCA) is proposed for intra‐frame EC. For inter‐corrupted MBs, a hybrid method comprising Directional Textural Motion Coherence Algorithm (DTMCA) and Directional Interpolation Error Concealment Algorithm (DIECA) is suggested. Experimental outcomes on several 3D MVV frames demonstrate that the suggested EC algorithms have more robustness to both heavily random and slice losses. They objectively and subjectively work better than the state‐of‐the‐art EC techniques. The proposed work achieves high 3D MVV quality with an improved average Peak Signal‐to‐Noise Ratio (PSNR) gain up to 2.45 to 4.55 dB compared with traditional EC algorithms at Packet Loss Rates (PLRs) of 40%.
