| 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。

| Abstract: | 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. |
