【摘要】 本文探讨了视频流在网络多路径传输的模型,并在此基础上提出了四种不同复杂度,不同性能的鲁棒性的解码方法,以适应网络传输多样化的环境需要。根据实验结果表明,基于运动估计的具有错误掩盖的解码方法性能最佳,但是复杂度比较高,前后帧替代的具有错误掩盖的解码方法性能最差,但是算法复杂度比较低。更多还原

【Abstract】 Multi-path transmission model of the video streaming on networks is presented,On this foundation,four decode algorithms with different complexity and performance of robust code are also proposed to fit the varied condition of network transmission.According to the simulation,it is showed that,the algorithm of the motion estimation and compensation with the best quality is more complexity than others,and the algorithm of forward and backward predict with low quality is easier than others.更多还原
