摘　　要：文中旨在通过编辑ASF文件实现多媒体间的同步。所采用的方法是在深入解析ASF文件内部结构的基础上,利用VisualC++6.0为开发工具,完成一个针对ASF文件的编辑工具的开发,并利用此工具编辑已有的ASF文件,向其中添加脚本命令对象并利用其实现流媒体与其它媒体间的同步。经过实践证明此方法是一种有效可行的多媒体间的同步实现方法。较之其它的多媒体间同步方法,这种方法实现的同步更为精确,操作更为简便,而且这种同步方法实现的是流媒体文件与其它媒体间的同步,为流媒体的应用给出了一个创新方式。The research aim of this paper is through editing ASF file realize the synchronization of multimedia. The method being adopted is that using Visual C++ 6.0 to explore an ASF editing tool ,and using it to edit ASF file to realize multimedia synchronizing play ,which is based on the deeply parse of the ASF file inner structure and the script command object has been added into the ASF file successfully.Testified by the practice ,the method is an effect and feasible synchronizing method between multimedia. Comparing with other synchronizing methods, the synchronization made by this method is more exact, and the operation of this method is more simple. Furthermore, the synchronization made by this method is between the stream media and other media, which is giving an inaugurating mode of the application of the stream media.
