摘要
电子节目指南是数字电视标志性的功能之一，为用户收看电视节目和享受信息服务提供了一种良好的导航机制。该文首先阐述了电子节目指南（EPG）的作用和研究意义，之后介绍了EPG的信息来源以及PSI／SI信息收集与解析的算法，提出了一种数字电视软件系统中PSI／SI信息搜集的实现方法，最后介绍了EPG功能模块及其主要函数接口。EPG功能模块以PSI／SI过滤与解析模块为基础，模块化设计方便了数字电视系统的移植与维护。
Electronic program guide （EPG） is one of the iconic features of digital TV, and provides a good navigation system for users to watch television programs and enjoy information services. First of all, this article describes the role of EPG and significance of studying EPG, then describes the sources of EPG information and the algorithms of collecting and analyzing PSI / SI information, proposes a kind of method of the digital television software system collecting PSI/SI information, and finally describes the EPG function module and its main function interfaces. EPG function module bases on PSI/SI fdter and analysis module, the modular design facilitates migration and maintenance of the digital TV system.
