The Research And Realization Of Synchronization Technology Between Multimedia

With the development of computer technology, especially the popularization of the stream media, it make the applications based on the stream media has penetrated into every walk of our life including VOD video session remote seminar education etc, and the technology based on the stream media make a huge development at the same time .Traditional technology of multimedia is not suit for the development of Internet anymore, especially, the transmission and synchronization of multimedia become the hotspot of research. The appearance of the stream media handle the transmission problem of multimedia successfully, it shorten the time of transmission greatly, moreover, it needs little capability of cache. At the same time , the research of synchronization of multimedia made a great progress.Under the background, through the research of the current technology of multimedia synchronization and the stream media, this article discusses an application in synchronization of multimedia based on the ASF stream media files, contraposing an example , established a model and gave two methods of the synchronization, realized the entire process of synchronization. This article is made up of five chapters , and the basic content of each part is:The first chapter introduces three technologies of the stream media currently, through the systemic summarize file compression mode server and client etc and contraposing the three systems of the realization of the stream media , gives a detailed introductionand compare , and bring forward the content and aspect of the research.The second chapter introduces several models and methods from the angle of multimedia synchronization , at the same time introduces a popular technology of multimedia synchronization -SMIL.The third chapter , in allusion to a example , based on the particularly introduction of the format and inner form of Media player and ASF , established a synchronization model based on the time line model and decide using two kinds of methods to realize the synchronization.The fourth chapter introduce the whole procedure of the synchronization , at last parse the advantage and disadvantage of two kinds of methods and finally decide to use the reference method to realize the synchronization.The fifth chapter , based on the summarization of the whole article , prospect the research and development of the stream media technology.
