Although streaming media technology is widely used, its multimedia stream playback quality is low because of datatransmission delay and jitter.
流媒体技术应用越来越广泛，但数据传输中的延迟、抖动，影响了媒体流播放质量。

In order to reduce the datatransmission traffic, filtering the datastream that will be transmitted can be adopted besides taking DR algorithm and improving communication method.
为了减少传输的数据量，除了采用DR算法和改进通信方式外，还可以对将要发送的数据流进行过滤。

It copies the original datastream to several parallel data streams, spreads them in both time and frequency domain, then modulates them to orthogonal sub-carriers for transmission.
