Probability Estimation based Adaptive Media Playout Algorithm

摘要：

An adaptive media playont algorithm based on probability estimation is proposed to reduce the video playont jitter and playout halt caused by buffer underflow. It adjusts the duration of each frame according to the channel state and the estimated probability of underflow and overflow. Also it controls the playout rate range and the variation of the playout rate of the consecutive video frames to achieve the purpose of eliminating buffer outage and smoothing the video playout speed at the same time. Simulation results demonstrate that as compared to other AMP schemes, the proposed algorithm provides better visual quality with reasonable complexity in reducing the probability of buffer underflow and reducing the playout latencies and smoothing the visual perception.
