中文摘要：

为了实现基于BREW平台提供移动视频点播服务，提出了一套相对完整的、可以在联通CDMA20001X网络上运行的移动流媒体系统解决方案．该方案包括节目源制作、流服务器和客户端3部分．视频编解码采用H．264标准、音频编解码采用BREW平台提供的PureVoice技术．该系统可以提供流媒体内容的点播服务，并可以支持播放、暂停、快进、停止等4种VCR功能．在联通CDMA20001X网络上的试运行结果表明，在网络带宽较低（70kb／s）的情况下，本系统可以为移动用户提供音画质清晰、流畅的多媒体服务，视频可达到8帧／s．

英文摘要：

In order to provide mobile video on demand services on BREW （Binary Runtime Environment for Wireless） platform, a relatively integral streaming media system solution which can be deployed on CDMA2000 IX network, is presented. The solution consists of three independent parts： streaming media creator, streaming server, and streaming client. Video source data is compressed by H. 264 codec, and audio source date is compressed by using PureVoice coding technology offered by BREW platform. The proposed system can provide on-demand service of media contents. And four VCR （Video Cassette Recording） functionalities, including play, pause, fast-forward, and stop, are well supported. Application experiments on Unicorn CDMA2000 IX network show that the proposed solution can provide vivid and fluent multimedia contents at lower bandwidth （70 kb/s） with relative high video frame rate, which can be up to 8 fps, for the wireless mobile subscribers.
