摘要
通过对中国移动多媒体广播(CMMB)系统帧结构、复用特征的分析,提出该系统解复用的一种软件实现方法。该方法中,对控制信息和业务信息分开进行解复用,根据得到的控制信息,解析出码流中的音频和视频数据,通过同步后送入播放器部分。该方法用软件实现起来非常方便,不仅能降低系统实现的复杂度,而且系统升级非常方便。
In this paper, the frame structure and multiplex characters of China Mobile Multimedia Broadcasting (CMMB) system are analyzed, and a solution scheme of de-multiplexer is presented. The control of information is used in this scheme to de-multiplex the video and audio data, and then the stream is spreaded into the player. This method is very convenient to achieve. The plan can not only reduce the implementation complexity, but also upgrade the system easily.
