Video transmission over noisy channels makes error concealment an indispensable job. Utilization of data hiding for this problem provides a reserve information about the content at the receiver, while unchanging the transmitted bit-stream syntax; hence, improves the reconstructed video quality with almost no extra channel utilization. A spatial domain error concealment technique, which hides edge orientation information of a block, and a resynchronization technique, which embeds bit-length of a block into other blocks are composed. The proposed method also exploits these two techniques for detecting errors via some extra parity information. Moreover, the motion vectors between consecutive frames are also embedded into the consecutive frames for better concealment at the receiver. Finally, as a novel approach, the bit-streams are further protected against errors via channel codes and the parity bits of these codes are embedded into other slices. In this manner, implicit utilization of error correction codes improves the reconstruction quality significantly. The simulation results show that the proposed approaches perform quite promising for concealing the errors in any compressed video bit-stream.
