AVS-M　is　a　video　encoding　standard　used　for　mobile　video　in　wireless　environment,　developed　by　the　Audio　and　Video　Coding　Standard　Working　Group　of　China.　In　order　to　cope　with　the　burst　error　in　error-prone　wireless　networks,　in　this　paper,　we　present　an　error　tracking　mechanism,　which　utilizing　a　feedback　channel　to　judge　which　areas　are　contaminated　by　the　prediction　from　its　preceding　frames.　Through　this　positioning,　we　can　terminate　the　error　propagation　effects　by　INTRA　refreshing　the　affected　areas.　Simulations　demonstrate　that　the　proposed　algorithm　can　effectively　stop　the　quality　degradation　and　not　cause　much　bit-rate　increase.　©2009　IEEE.
