Abstract :
Recently, data hiding has been proposed to improve the performance of error concealment algorithms. In this paper, a new data hiding-based error concealment algorithm is proposed, that allows the increase of video quality in H.264/AVC wireless video transmission and real-time applications. Data hiding is used for carrying to the decoder the values of some inner pixels to be used to reconstruct lost macro blocks into intra frames through a bi-linear interpolation process.
