Multi-view video sequences are compressed using advanced high compression ratio tools called H.264/AVC multi-view coding (MVC). MVC is very sensitive to errors due to its structure as a result Error Concealment (EC) algorithms are developed at the decoder to improve the quality of decoded MVC frames. In this paper efficient multi-view EC algorithms are proposed for intra and inter MBs. For Intra MBs, Spatial-Inter View (SIV) algorithm is proposed. For inter MBs, the proposed algorithm is adaptively changed according to the lost MB size. In addition, the algorithm dynamically candidates MBs according to the current used view. Then, the inter 16 × 16 MBs are enhanced by a new method called Weighted Block Motion and Disparity Concealment (WBMDC). The other inter MBs types are enhanced using a proposed method called the Overlapped Block Motion Compensation (OBMC). It is shown that the proposed algorithm leads to better subjective quality in addition to higher PSNR values. By applying the proposed algorithms, the gain is improved by up to 12.84 and 1.1 dB comparing to no applying any EC algorithms and applying normal EC algorithm respectively at 22 % Loss Rate (LR).
