摘　　要：为提高H.264/AVC编码码流在3G网络上的传输性能,结合3G无线信道的典型特征,提出一种基于反馈信息的多参考帧选择与错误隐藏技术相结合的差错控制方案,并给出适合3G双向视频传输的模拟模型。仿真实验表明,该方法可以提高重建图像的峰值信噪比。In order to improve transmission performance of an H. 264/AVC coded stream in 3G wireless network, combined with the typical characteristics of 3G wireless channel , a novel error scheme adopting both error concealment technique and reference picture select based on feedback channel is presented. A video communication simulation model is presented, which was suitable for bidirectional conversational video transmission simulation in 3G wireless network. Simulations show that the scheme achieves improvement of the reconstructed video peak signal noise ratio.
