数字电视EPG信息解析系统的设计与实现
摘要
电子节目指南是数字电视系统的节目导航工具,随着数字电视的迅速发展,已经成为了国际研究开发的热点之一。本文对数字电视中EPG信息解析系统的实现进行研究,对我国EPG应用的实现推广有较大的现实意义。
本文首先深入分析了数字电视中的电子节目指南的相关标准,接着对EPG信息的解析技术作了深入的研究,设计了基于DVB-SI标准的EPG信息解析系统。该系统实现了对符合DVB标准的数字电视节目传输流的解析,并基于解析得到的EPG信息生成EPG信息数据库,实现节目浏览、节目预订、频道收藏和家长分级控制等基本EPG应用。最后文章通过应用实例证明系统的设计方案是可行的。
EPG (Electronic Program Guide) is the program navigation tool of digital television. With the rapid development of digital television, it is becoming one of the hot topics. This paper studies on the implementation of the EPG information analysis system and has significance in promoting the realization of EPG application in China.
In this paper, firstly, we deeply analyze the related specifications of EPG. Secondly, we further study the technology of extracting the EPG information from the transport stream. Then, we design the EPG information analysis system based on DVB-SI. This system can extract the EPG information from the program transport stream of digital television based on DVB to build the EPG database. It implements basic EPG application, such as program list, program subscribe, favorite channel, parental lock. Finally, this paper gives an application example to validate the feasibility of the system.
