摘要
针对流媒体传输过程中的丢包和不均匀延迟现象,提出了改进的MPEG-4自适应算法.该方法根据预测误差的反馈动态改变步长大小,具有灵活的自适应性.仿真实验表明,可以明显地改善流媒体的自适应传输性能.
This paper advances an improved adaptive arithmetic of MPEG-4, in allusion to resolve the problem of lose pack and asymmetry delay phenomena in streaming transmission. This method changes step size dynamically based on the feedback of prediction error. It has the merit of flexible adaptive capacity. Much emulate experiment validate, this method can distinctly improve the adaptive rate transmission of streaming media.
