摘要 数字多媒体广播电子节目指南(DMBEPG)是数字电视行业内一项重要的应用,也是用户通过手机获取节目信息的必不可少的工具。在DMBEPG系统中,减小文档大小、改善传输性能非常重要。本文探讨了EPG系统的XML数据存储技术和基于传输性能的XML数据编码问题。在分析研究DMBEPG协议原理的基础上,设计和实现了DMBEPG系统的XML数据存储和二元编码过程,并对三种编码方案的性能进行了分析比较。 Digital Multimedia Broadcasting Electronic Programme Guide （DMB EPG）, is an important application of digital TV and an indispensably tools for users to know about programs by mobile telephone. In the DMB EPG system, it＇s very important to reduce the document size of transportation and improve transportation efficiency. In this paper, XML data store technology based on EPG system and XML data encoding problem based on transportation efficiency are discussed. On the basis of studying a series of protocols, Principles of DMB EPG, the DMB EPG XML document storage scheme and binary encoding process are designed and implemented. Additionally, the efficiency of three encoding schemes is analyzed and compared.
