Performance analysis of region of interest video transmission system

We investigate the video transmission efficiency of channel code, modulation mode and layered space time code for region of interest video transmission system. Excellent channel code achieves more coding gains, suitable modulation mode adaptively overcomes different channel fading and layered space time code achieves not only coding gain but only diversity gain. Based on the above analysis, we propose an adaptive video transmission system according to channel environment and video constructed quality require. We derive an analytic bound for the error probability, and conduct experiments for H.264 interest of region video streaming. It is shown that the proposed system enhances the PSNR performance of region of interest significantly by adaptive choice of channel code, modulation mode, and layered space time code in the wireless channel.
