As dynamic delivery of video over HTTP becomes prominent, rate adaptation techniques become more challenging due to bandwidth variations. This paper presents a Fuzzy-based controller to dynamically adapt the video bitrate based on both the estimated throughput and the size of the playback buffer. The proposed Fuzzy Logic Controller (FLC) mechanism takes the observed throughput and buffer dynamics as inputs to change the policy of selecting the video bitrate and download scheduling to minimize the negative effect of ON-OFF switching. The experimental results show that our proposed mechanism generates a smoother stream compared to existing methods.
