In recent years

multiple description coding(MDC) had been proposed to address robust video transmission problem over error-prone networks.In this paper

a macroblock splitting based multiple description scheme is proposed

and the corresponding redundancy control and mismatch control methods are also given.The proposed scheme is easy to be realized and compatible with the video coding standard.Experimental results show that the proposed scheme of multiple description video coding outperforms the optimal DCT coefficient splitting scheme and the MDTC scheme.
