| 摘 要： | 无线视频编码的低抗误性、无线信道带宽的有限性、无线视频业务的高需求决定了高鲁棒性的抗误算法必将成为无线视频通信的核心问题之一.基于FEC与WZ (Wyner-Ziv)两抗误工具的在不同误码率下抗误互补特性,提出了FEC与WZ联合抗误码方案.实验表明:该方案有效地综合了两者优点,提升了平均PSNR.

| Abstract: | Reliable video delivery has become one of the crucial issues in wireless video communications because of low error resilience ability of wireless video coding, high interference property of wireless channel and the high demand of the wireless video services . Based on there natural characters of FEC and WZ (Wyner-Ziv), we propose an error resilient coding scheme which combining the two technologies. Experimental results demonstrate the scheme can possess their both advantages and have an improvement in the average PSNR. |
