均值变点是统计学中常用的变点分析方法，其主要思想如下： 假设有一组数据，随着某个指标变化（增大），其值逐渐增加并趋于稳定，如何判断在这个过程中是否出现了突变的情况，异样的情况？ 均值变点分析方法提供了一种思路，大概如下： 1 计算总的均值和方差； 2 循环将这组有序数据分成两组，X1，X2 计算各组的均值和方差， 计算总方差与分组方差之和的差； 3 得到变点(The change point of mean is a commonly used change point analysis method in statistics. Its main ideas are as follows: If there is a set of data, as a certain index changes (enlargement), its value increases gradually and tends to be stable. How to judge whether there is a sudden change in the process and the unusual situation? The mean change point analysis method provides a way of thinking, which is as follows: 1 the total mean and variance are calculated. The 2 cycle divides the ordered data into two groups, X1, X2. Calculate the mean and variance of each group. The difference between the sum of the total variance and the group variance is calculated. 3 get a change point)

NetTalk是一个适用于局域网和因特网的可视电话软件 一．开发环境 Windows2000 Server & Visual C++6.0 & SDK +自开发的CWndX类库(相当于简化的MFC涉及窗口的部分) 二．支持环境 Windows98/ME/2000/XP 三．所涉及协议和标准 网络传输采用UDP协议，音频压缩采用G.729标准，视频压缩采用H.263标准 四．性能参数 以音频帧为基准，每帧音频数据有２４０个采样点，时间为２４０＊１０００／８０００＝３０ms，８０００为音频的采样率。 数据接收端队列缓冲延迟：３０＊3＝90ms 数据发送端录音延迟：30ms 数据压缩解压耗时：
