超文本传输协议(HTTP)流媒体技术已经广泛应用于多媒体传输。为了适应异构网络和不同终端的需求,本文设计了速率自适应控制器作为视频传输系统的核心部分。在本文中,三输入模糊控制器的设计,以提高用户的体验质量(QoE)在观看在线视频。模糊逻辑的引入解决了基于缓冲器的自适应控制器中没有规则来设定合理缓冲阈值的问题。归一化吞吐量、缓冲器水平和缓冲器变化被用作控制器的输入,以最小化由有限比特率水平引起的不可避免的失配,并帮助系统收敛到稳定状态。在三种模拟网络条件和实际车辆条件下将所提出的控制器与其他三种控制器进行了比较。同时使用QoE模型来获得直观和全面的结果。结果表明,在所有四种情况下,所提出的控制器都能提供比其他算法更好的QoE。
HyperText Transfer Protocol (HTTP) streaming has been widely used for multimedia delivery nowadays. To adapt to the heterogeneous networks and different terminals, the rate adaptation controller is developed as the core part of the video transmission system. In this paper, a three-input fuzzy controller is designed to enhance the users’ quality-of-experience (QoE) on watching online video. The introduction of fuzzy logic is able to solve the problem that there is no rule to set the reasonable buffer thresholds in the buffer-based adaptation controller. The normalized throughput, the buffer level and the buffer variation are used as the inputs of the controller to minimize the inevitable mismatch caused by limited bitrate levels and to help the system converge to a stable state. The proposed controller is compared with three other controllers under three simulation network conditions and an actual vehicle condition. A QoE model is simultaneously used to get intuitive and comprehensive results. The results show that among all the four conditions, the proposed controller can provide better QoE than other algorithms.
