Abstract :
H.264/AVC has a new error-resilient tool called flexible macroblock ordering (FMO). In this paper, we present a method to generate explicit FMO map based on distortion by simulating spatial and temporal error concealment at the encoder and a new error concealment method at decoder for wireless network. The error concealment method at the decoder is applied according to the residual information derived from the distortion simulation at the encoder that generated the FMO map. Our simulation result indicate the our proposed method of explicit FMO map generation and error concealment scheme could reduce the number of undecodable MB and improve quality of video under wireless network.
