A Streaming Transmission Scheme for DVC over Wireless Mobile Ad hoc Networks

Abstract

In order to improve quality of reconstructed frame for distributed video coding(DVC) over wireless mobile Ad hoc networks, a streaming transmission scheme with burst loss tolerance over wireless mobile Ad hoc network was proposed. Consider the fact that non-linear of pixel movement in distributed video coding sequences, the neural network was designed and trained offline using different standard distributed video sequences to achieve generalization. Therefore, the neutral network was exploited to predict the GOP size of distributed video coding sequences, and the rate control method which could be adaptive adjusts the feedback time for blocks in frame was proposed. The Experiment results show that the proposed scheme for DVC has a superior PSNR performance compared with conventional scheme, and enhanced the quality of video in wireless mobile Ad hoc network.
