N2 - For entropy-coded MPEG-2 video frames, a transmission error will not only affect the underlying codeword but also may affect subsequent codewords, resulting in a great degradation of the received video frames. In this study, transmission errors in MPEG-2 video frames are first detected and located by the error detection scheme proposed by Shyu and Leou [1999], and then the corrupted blocks are concealed by the proposed hybrid error concealment scheme. Based on the condition of a corrupted block, a corrupted block in an intracoded I frame is concealed by either the spatial error concealment algorithm in H.26L test model long-term number 9 (TML-9) or the best neighborhood matching (BNM) algorithm followed by the proposed modified spatial anisotropic diffusion (SD) algorithm. A corrupted block in an inter-coded P or B frame is concealed by the proposed motion-compensated BNM algorithm. Based on the simulation results obtained in this study, the proposed scheme can recover high-quality MPEG-2 video frames from the corresponding corrupted video frames up to a bit error rate of 0.5%.
