一种自适应调整抖动缓冲区大小的算法

One Kind of Auto-Adapted Adjustment Jitterbuffer Size Algorithm

在利用IP电话进行语音通话时,话音的QoS(Quality of service)是衡量IP电话好坏的重要指标。为了提高IP电话的QoS,当前已经提出了很多提高语音QoS方面的策略,其中比较著名的方案有:IntServ/RSVP(集成服务/资源预留),DiffServ(区分服务)、MPLS(多协议标签交换协议)等。中文主要是基于语音的接收端,设计一种自适应调整抖动缓冲区的大小的一种算法,从而消除语音时延抖动,提高语音通话质量。

When carries on conversation making use of the IP telephone, to judge the IP telephone, the QoS （quality of service） nothing but is the important index. In order to improve the IP telephone＇s QoS, it has already appeared a lot of strategies for enhancing voice. Among them, quite famous plan has： IntServ/RSVP, DiffServ, MPLS. This paper is mainly based on the receiving terminal, design one kind of auto- adapted adjustment buffer＇s algorithm which eliminates the delay jitter and improves the pronunciation connection quality.
