Abstract	The paper presents a novel adaptive error concealment algorithm for image coding. In order to control the quality of the reconstructed images, the motion compensation result of each macroblock is judged at the encoder end to determine the data transmission scheme to be used. If the compensation quality is low enough, the coding data of the macroblock is transmitted twice to ensure the quality of the reconstructed image in case one of the blocks may be contaminated during transmission; if the quality is high enough, the coding data is not transmitted, since this block can be reconstructed by using the compensation one at the decoder end with high quality; if the quality is between the two cases, the coding data is transmitted once as in conventional methods. In this way, the quality of the decoded images can be guaranteed without obviously increasing the transmission data. The validity of the proposed algorithm is confirmed by the results of simulations.
