A motion picture coding scheme with high error resiliency that is applicable to wireless communication is proposed. Two methods are introduced to minimize the degradation of decoded images : re-synchronization method recovers synchronization from bit-slip of a VLC and two-way decoding using reversible VLC. To recover erroneous decoded images, an adaptive refreshing method is applied in which the encoder selects non-stationary areas for refresh by using the coding mode of the past frames. Simulation results show that the proposed scheme has high error resiliency and is applicable to high error prone environments with BER larger than 0.1%.
