A method for performing temporal error concealment is provided. The method includes the following steps: detecting a damaged macroblock having four 8×8 damaged blocks; obtaining motion vectors of a plurality of 4×4 neighboring blocks surrounding the damaged macroblock; and for each of the 8×8 damaged blocks, determining a predicted motion vector according to motion vectors of six of the plurality of 4×4 neighboring blocks which are closest to the 8×8 damaged block.
