This paper proposes a scheme for error-resilient transmission of videos which jointly uses intra macroblock\r\nrefreshment and redundant motion vector. The selection of using intra refreshment or redundant motion vector is\r\ndetermined by the rate-distortion optimization procedure. The end-to-end distortion is used for the rate-distortion\r\noptimization, which can be easily calculated with the recursive optimal per-pixel estimate (ROPE) method.\r\nSimulation results show that the proposed method outperforms both the intra refreshment approach and\r\nredundant motion vector approach significantly, when the two approaches are deployed separately. Specifically, for\r\nthe Foreman sequence, the average PSNR of the proposed approach can be 1.12 dB higher than that of the intra\r\nrefreshment approach and 5 dB higher than that of the redundant motion vector approach.
