circular buffering

this paper presents a scheme to implement a voice real-time transmission system, in which we use amr coding of wcdma in 3g for reference. the system is based on multi-thread technology and circular buffering queue mechanism, as well as udp.

借鉴3G中WCDMA标准的AMR语音编码算法，结合多线程和循环缓冲区队列的方法，并采用UDP协议，给出了一个语音实时传输系统的实现方案。

buffer module stores audio-video packets which received and processed by the network module to the circular buffering queue to solve the problem which caused by packets loss, jitter and packets reordering.

缓冲模块把从网络模块接收到的音视频数据包进行处理，然后将处理后的数据存储在循环队列中，以此来缓解网络丢包、抖动和乱序引起的问题。

stream mode writes to a circular buffering file, called stream. out.

流模式将事件写入循环的缓冲文件stream.out中。
