In this paper, a high efficient temporal error concealment scheme based on auto-regressive (AR) model is proposed for video coding. The proposed AR based error concealment scheme includes a forward AR model for P slice, and a bidirection AR model for B slice. First, we utilize the block matching algorithm (BMA) to select the best motions for lost blocks from the motions of available neighboring blocks. Then, the proposed AR model coefficients are computed according to the spatial neighboring

... els and their temporal-correlated pixels indicated by the selected best motions. Finally, applying the AR model, each pixel of the lost block is interpolated as a weighted summation of pixels in the reference frame along the selected best motions. Simulation results show that the performance of the proposed scheme is superior to conventional temporal error concealment methods.
