We propose an error concealment method for robust video transmission based on watermarking technique. In this method, the motion vector information is used as the watermark and embedded in the transform coefficients before quantization. A proper embedding algorithm is designed with the characteristics of the video coder taken into consideration, so that the embedding watermark has little influence on the video quality and the coding efficiency. At the decoder, the extracted watermark is used to effectively detect errors and restore the corrupted motion vectors. Then the restored motion vectors are utilized in error concealment. Simulation results demonstrate the advantages of the proposed method in error prone environment. The proposed method is applicable to all the block-transform based video coding schemes. © Springer-Verlag Berlin Heidelberg 2005.
