摘　　要：为解决传统的媒体流识别方案只能根据媒体流使用的协议特征识别媒体流，无法识别媒体流所属业务类型的问题，本文在深入研究IPTV通信过程的基础上，提出了一种对IPTV各个协议进行关联分析，然后提取各个协议之间的关联信息和各个协议自身的特征信息，运用正则表达式对这些信息进行描述，可以精确识别属于IPTV业务的媒体流的技术方案。实验表明本技术对IPTV媒体流的识别具有很高的识别准确率。To solve the problem that the traditional media stream identification program can only use the media streaming protocol characteristics to identify the media stream and can＇t recognize the media stream to their business type, on the basis of the further research of the communication process of IPTV, this paper proposes an technical scheme that makes correlation analysis of each protocol of IPTV, and then extracts each protocol＇s characteristics and association information between them, and uses regular expressions to describe this information and characteristics, and accurately identifies the media streams belonging to the IPTV service. Experiments show that the identification of the IPTV media streams with high recognition accuracy.
