摘要 提出了一种支持MPEG-4可变比特率视频业务模型,用Kalman优化的方法,对未来帧进行线形预测,而不需要更多的先验信息,进行动态带宽分配,提高带宽的利用率。用这种方法,对MPEG-4业务进行建模,并利用该模型讨论了在不同带宽利用率的情况下的丢包情况,实验仿真结果表明,该方法与实际视频业务在相同条件下的丢包率误差较小,适于实时视频业务的预测与资源预留。 A prediction method to support MPEG-4 variable bit rate (VBR) is proposed. Using Kalman optimized method to model and predict MPEG-4 video traffic, any prior knowledge of the traffic statistics does not need. Comparisons of loss probabilities between the actual traffic and the prediction traffic, the errors is very small. Simulations show the prediction method for future frames is efficient.
