The related screening method for decoding error comprises: deciding whether there is error in current input dynamic video flow; if some macro-block error in current dynamic video frame, determining whether the macro-block belongs to the first one; if not, estimating MV value of motion vector for macro-block in last frame; to use SAD (Sum of Absolute Difference) value, selecting macro-blocks near the error one; calculating SAD value for selected and reference macro-blocks, and selecting error screening method for execution. |
