【摘要】 分析分多媒体监控特点,认为多媒体流的QoS保证是一个重要的研究课题。提出了支持自适应QoS保证的嵌入式IP网络多媒体监控系统模型。QoS保证方案包括系统资源监测,网络带宽的预估计,借助PID算法实现多媒体自适应流的自调节,以及音频优先保证。实验表明,该模型结构简单,制定的QoS控制策略能够实时地对视音频参数进行动态调整,资源利用率高,图像传输流畅。更多还原

【Abstract】 After analyzing the features of multimedia monitoring system,we know guarantee of multimedia streams is a key problem.An IP network multimedia monitoring system model with adaptive QoS guarantee is proposed.This QoS guarantee scheme consists of the monitoring of system resource,the available bandwidth future estimation,the implementation of multimedia self-regulating by PID algorithm and the audio priority.Experiments show that this model has simple structure,high resource availability.The QoS control policy can dynamically adjust the real-time parameters of video and audio,and images can be transported fluently.更多还原
