Best-effort streamed video playout representing the most popular and cost-effective multimedia application today is unfortunately very sensitive to any fluctuations in packet loss and delay. There are always further problems for the provision of real-time playout applications over wireless links because of the complicated and highly variable nature of the channel and challenging quality issues for adopting the service in global scales, which necessitates adopting a new and effective buffer mechanism. As a solution to this problem, to smooth out the playout for quality viewing and improved overall systems' performance, in this study the authors propose a new adaptive media playout (AMP) system that makes the most effective use of a packet-delay prediction algorithm. Here, as the prediction method makes decisions based on the delay interdependency of the adjacent packets the differential auto-regression delay prediction model is used for working out the estimation. The proposed algorithm also adopts more refinement changing steps in the adjustment process and takes into accounts any packet losses with deadline constraint. The simulation results show that the proposed method outperforms the AMP-live method in reducing the average buffer delays as well as enhancing package loss rates for both overflow and underflow.
