Özet
Utilization of data hiding for concealment of video transmission errors provides a reserve information about the video to the receiver while unchanging the transmitted bit-stream syntax; hence, improves the reconstruction video quality without 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 arc composed. The proposed method also uses these techniques for detecting errors. Simulation results show that these approaches cooperate quite well in
