To reduce the influence on video decoding quality induced by transmition error
This paper analyzes several classical error concealment methods and evaluates them on AVS-M. Based on the test result
an adaptive spatial-temporal error concealment (ASTEC) algorithm is proposed. According to the boundary matching degree of switch between spatial/temporal concealment methods adaptively. Simulation results show that
compared with the original spatial and temporal method
the proposed algorithum achieves better performance
