摘要 针对无线视频通信中现有差错控制方法的缺点和局限性,结合3G无线信道高误码率和高时变性的特点,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。 Aimming at the shortcoming and limitation of existing error control scheme in wireless video delivery,combined with the characteristics of high errorrate and time variability in 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 is 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.
