摘　　要：通过音频与视频解码器和相关的音视频流方案实现上位机与下位机音视频流数据的编码解码及重新合成,并给出了音视频在播放过程中实现同步校正的方法,实现了在有高音质外放设备情况下的上下位机播放的准确同步。系统在Android平台上已获得实现,所使用的音视频实时分离及同步播放方法能成功实现智能终端视频播放和高音质外放音频播放的准确同步,并在上位机成功合成新的音视频文件。Through the audio and video decoder and audio and video streaming solutions, this system achieves the audio and video streaming data＇ s encoding, decoding and re-synthesis of the host computer and the lower computer. And it gives a synchronized-correction method during the playback of audio and video. It also achieves the accurate synchronization of the host and the lower machine in the case of the high-quality external devices. This system has been achieved on the An- droid platform. The method that is used to make the real time separation and the synchronized playback of video and audio can successfully achieve the accurate synchronization between the intelligent terminal video playback and the high-qualityaudio playback. It also successfully synthesizes new audio and video files on the host computer.
