摘　　要：结合3G无线信道的典型特征,提出了1种基于数据分割冗余包和FMO的视频容错传输方案,并在ITU提供的标准无线信道模型中进行了仿真测试.实验证明,该方法达到了较好的传输码率与数据差错复原能力的平衡,使解码图像获得了较好的质量.Combined with the typical characteristics of 3G wireless channel, a novel error resilience video transmission scheme adopting both data partition and FMO（Flexible Macroblock Ordering） is presented. A standard wireless model provided by ITU is exploited to carry out the simulation experiments. The results demonstrate that it achieves a better tradeoff between bit rate and error resilience ability as well as satisfying reconstructed picture quality.
