An Algorithm for Real-time Video Continuous Playback Based on PI Controller Over IP Network

In order to eliminate the influence of network disturbance on continuous playback of streaming media.An algorithm for real-time video continuous playback based on PI controller is proposed,which deals with the problem in the sink.The playback rate is controlled by PI controller,which is applied to achieve continuous media playback by controlling the buffer level of the sink.A framework of real-rime video transmission based on TFRC is constructed to get real influence of transmission on video playback.Experiments show that compared with the existent methods it has especially better playback quality and that the probability that the buffer overflows or underflows is smaller and that the real-time capacity is great improved for end-to-end average delay of video frame is shorter.
