针对无线网络存在的自相似特性会影响视频流的播放质量问题,提出了基于滑动窗口的接收端播放缓存调整算法,根据网络流量的变化,动态地调整双门限,并利用播放缓存的占用率来控制视频流的播放速度,平滑时延抖动.仿真实验证明,无论网络流量处于平稳状态还是处于突发状态,本文设计的算法都能够较好地保证视频流的连续播放,提高视频流的播放质量,为用户提供良好的视觉效果.
For the existence of self-similar wireless network will affect the playback quality of video streaming, a sliding window based on the receiving buffer playback adjustment algorithm, according to changes in network traffic, dynamically adjust the double threshold, and use the playback buffer occupancy rate to Control the playing speed of the video stream and smooth the delay jitter.The simulation results show that the algorithm designed in this paper can guarantee the continuous playback of the video stream and improve the playback quality of the video stream, no matter the network traffic is in a steady state or in a sudden state. , To provide users with good visual effects.
