摘　　要：设计一种适用于3D视频传输的模糊自适应算法,选用缓存状态和估计网络吞吐量作为视频质量选择依据.不同于2D视频传输,设计自适应算法同时考虑视点选择对用户观看视频质量体验影响.实验表明,在几种常见变化网络环境条件下,算法可以为网络视频用户提供更好的质量体验.A fuzzy adaptation controller was designed for 3D-DASH transmission,considering the buf-fer size and the estimated throughput as the factors influencing the selected bitrate.And the number of viewpoints should be decided in 3D-DASH system,as it also can influence the quality of the viewers'ex-perience.Simulation results show that under several common network conditions,the algorithm proposed in can provide higher quality of experience for the video viewers.

关 键 词：DASH 立体视频 模糊控制 缓存大小 估计吞吐量
