Video communications over wireless channels is still a major problem due to limited bandwidth and the presence of channel errors. Low transmission rate in mobile networks requires a reduction of used video resolution as well as the use of highly efficient video compression technique. This gives rise to data loss and visual artifacts, and hence a marked decrease in video quality. Since the transmission of video content is over real time channel, it is not possible to re-send any erroneous or lost information. It is therefore necessary to conceal these errors at the decoder side using appropriate methods, such as Error Concealment (EC) methods. In this paper, we propose using of Dispersed Flexible Macro-block Ordering (DFMO) error resilience method in the encoder to aid the proposed Multi-Dimensional EC (MDEC) algorithms in the decoder to conceal the erroneous Macro-Blocks (MBs) of intra and inter coded frames of 3D stereoscopic video. Our extensive simulation results obtained demonstrate that the proposed combination algorithms can significantly improve the objective and subjective 3D video quality.
