In video transmission over two-way wireless channel automatic repeat request (ARQ) retransmission has been used to protect packets from losing, which also causes the channel throughput varying and brings more challenges to rate control of the video compression. This paper proposes a new rate control algorithm based on regions of interest (ROI), PID buffer controlling and perceptual tuning techniques, etc. It intelligently allocates bit budget among different regions and adapts to time-varying wireless channel so as to achieve better perceptual quality in ROI and depress the frame skipping. Simulation results illustrate that our algorithm effectively enhances the perceptual quality for ROI, significantly reduces the number of frame skipping, and thereby improves the smoothness of the video. |
