%X To solve the problem that image and video packets are liable to be lost when transmitted in packet switch network, a novel algorithm of image error concealment on DCT domain with low complexity was proposed. By using scalability coding technology, the coded image data were partitioned into two groups with different priorities according to their effects on the image quality in the encoder. When decoding, based on its attributes and the pre determined threshold, the lost image block was concealed. Simulation results show that by using the proposed algorithm, better image quality and quite lower computing complexity can be obtained.
