An Hybrid Error Concealment Method with Data Hiding for H.264 over Wireless Network

ABSTRACT With the development of internet, video communication becomes important in human’s life. H.264 is a new standard for video coding. It is very suitable for video communication. However, in a network, especially in a wireless network, transmission error is inevitable so that packet loss and bit error occur very often. In this paper, we propose a new hybrid error concealment method with data hiding for H.264. It combines the advantages of temporal error concealment (TEC) and spatial error concealment (SEC) for the loss of macroblocks. Also, we use a data hiding technique to embed the directional information for each 8 x 8 block for directional interpolation. Our method is suitable for the error concealment in H.264 video communication over wireless network. Experimental results of two video sequences called foreman and news show that the proposed method outperforms the conventional TEC and SEC and their hybrid method.
