VON Voice / Video Over the Net

In this paper,the method for measuring the QoS for VoIP network is introduced and the main elements affecting VoIP QoS performance such as delay jitter,packet loss and IP network delay analyzed.

文章介绍了VoIP(IP网络上传送语音)语音质量的测试方法,分析了影响VoIP语音质量的主要因素:延迟、抖动、丢包率和时延。

In IP-based networks,VoIP has become the representative technology of the next generation voice system,but its QoS is limited by the IP network capacity.

在以IP为基础的网络中,IP网络上传送语音(VoIP)成为新一代语音系统的代表,但其业务质量因由IP网络承载而受到限制。

As the advanced sensor networks,the audio/video sensor networks can provide rich multimedia information,which doubtlessly benefit data hungry applications such as environment monitoring,health care,emergency response and video security.

作为传感器网络的高级形式,音视频传感器网络在环境监控、安全监控以及医疗保健等诸多应用领域发挥重要作用。
