基于D-S证据理论的视频通信协议融合的研究
|
摘要
本课题的研究工作是结合导师科研课题“网络视频监控系统”展开的。近年来,随着网络和多媒体技术的发展,视频通信系统的研究得到了广泛的关注,同时各种多媒体通信协议的出现使得不同协议终端之间实现互联互通更加困难,视频通信协议的融合正逐渐成为多媒体通信系统的研究热点,解决各种视频通信协议之间的互通问题是现阶段视频通信领域面临的重要任务之一。
本文在查阅大量参考文献的基础上,论述了国内外视频通信协议和信息融合技术的发展历史和现状,针对目前各种视频通信协议混杂的现状,结合下一代网络部署中出现的一系列多媒体通信协议,提出了基于D-S证据理论的视频通信协议融合的解决方案。本文在详细分析多媒体通信系统中H.323、SIP、H.248和MGCP协议的基础上,给出了协议的消息格式以及协议间的相互关系。对不同视频通信协议采用不同的分析点提取方法,区分各种应用层协议并对协议进行认知处理。分析网络中抓取的数据包,判断通信双方的互通情况、识别通信协议,并把网络中相关视频通信协议消息保存在数据库中,根据不同视频通信协议消息的特点,通过D-S证据理论进行决策融合。设计协议消息存储数据库,根据系统的需要设计不同的数据表,用于存储各种类型的数据。通过同种协议视频通信终端间的通信过程以及异种协议终端间通信过程分析协议融合的实现过程,以及在处理协议融合过程中数据库的操作情况。本文在最后测试中以私有协议服务器与SIP协议终端的互通来对系统的实现进行验证。
本文给出了一种利用D-S证据理论对多协议视频通信系统进行融合的解决方案,它不仅可以解决主流公有协议间的互通问题,同时也为各种私有协议互通提供了一个重要参考,对于视频通信系统协议的融合互通具有重要的意义。
The research is carried out based on my tutor's scientific research project video monitoring network system. Nowadays, with the development of networks and multimedia, the research of video communication systems gets more and more attention. The communication among different protocol terminals becomes more difficult because of the emergency of many multimedia communication protocols, the fusion of video communication protocols becomes a hot research topic of multimedia communication systems. One important problem that video communication field faces is solving the intercommunication among different video communication protocols.
The development history and situation of video communication protocols and protocol fusion at home and abroad are discussed, after looking up in large numbers of references. There are many video communication protocols mixing up currently, and a series of multimedia communication protocols will emerge in NGN. The solution of video communication protocol fusion based on D-S evidence theory is put forward. The message format of protocols and correlations among the protocols are presented after analysing the H.323, SIP, H.248 and MGCP protocols in detail. Different analysis point extractions are adopted in different video communication protocols in order to differentiate every application layer protocol and do cognitive processing of the protocols. The data packets captured from the networks are analysed, the intercommunication situation is judged and the communication protocol is identified. The relevant video communication protocol message of network is saved in the database, Then the decision-level fusion among different protocols are carried according to different features of the video communication protocol message. The protocol message database is designed, and different datasheets are designed in terms of system's need to save all kinds of data. The implementation procedure of protocol fusion is analysed through the communication among the terminals using the same protocol and different protocols, also the operations of the database during the process of protocol fusion. The test of the system is carried by the intercommunication between proprietary protocol servers and SIP terminals in this paper.
The solution of multi-protocols fusion in video communication systems using D-S evidence theory is presented, which can not only solve the intercommunication of mainstream common protocols but also provide a reference for proprietary protocols intercommunication. The solution is of great significance in video communication system protocol fusion andintercommunication.
