In this paper, we present a new multiple description video coding method. It starts from GOB alternation to create two descriptions for each frame encoded, carriage of motion information in both descriptions helps to improve the quality of single channel reconstruction, and a process called low quality macroblock update helps to not only further improve the quality of single channel reconstruction but also reduce the mismatch between the encoder and decoder. The advantages of the proposed approach include: effectiveness, which has better performance than the well known MDTC video coder both in terms of Redundancy Rate Distortion, and in the packet loss scenario; low complexity, and standard compliant to the extent that each description can be decoded by a standard video decoder.
