一种自适应性网络多媒体应用架构

One Adaptive Network Multimedia Application Framework

网络多媒体应用要求实时性高、延迟小、误码率低。由于英特网的带宽资源是不稳定的,随时可能有拥塞,而且随着应用程序的起停,主机资源也是变化的,针对这种动态变化的环境,为了最大限度地利用资源并尽可能提供最好的视听质量,设计了一个基于DirectShow 的具有网络和主机自适应能力的组件应用架构,并在应用中取得了良好的效果。

Network multimedia application has high requirements in terms of real-time, delay and error-rate. As the bandwidth changes and applications are started and terminated, both resource requirements and availability change dynamically at run time. In order to maximize the resource utilization and provide best quality of presentation, we design an application framework based on DirectShow RTP with network and host adaptive capability which applys to many situation. ;;
