With the rapid development of digital television, EPG has been widely used in digital television. EPG helps the DTV viewers sort out their favorite programs quickly from hundreds of programs and make the viewers know the programs which will put on in the following days. In the meantime, EPG can provide TV users with many interactive applications, such as program reservation, categorization and parental control etc. From the economical point of view, we adopts Hi3110Q standard definition provided by helicons as the master chip, the 8M flash and 32M DDROM as memory chip.We also adopt the NEC remote control standard as the users’ control and Linux system architecture design to make it convenient for users to manage the EPG information and to operate the program. It reached every requirement through various tests,a video record has been made at the same time. Keywords: DVB; ARM ; EPG(Electronic Program Guide); Program Management 目录 摘要 I ABSTRACT II 目录 III 一 绪论 1 1.1 数字电视的发展 1 1.2 ARM芯片的发展 1 1.3 EPG的概念及其作用 2 1.4 论文主要完成工作及章节安排 3 二 EPG相关表结构 5 2.1 TS流(Transport?Stream) 5 2.2 NIT网络信息表(Nerwork Information Table) 6 2.3 PAT节目关联表(Program Association Table) 6 2.4 PMT节目映射表(Program Map Table) 6 2.5 SDT业务描述表(Service Description Table) 7 2.6 EIT事件信息表(Event Information Table) 7 三 系统设计 9 3.1 总体设计 9 3.1.1 概述 9 3.1.2 总体结构 10 3.2 启动流程及节目有哪些信誉好的足球投注网站设计 10 3.2.1 系统启动过程 10 3.2.2 节目有哪些信誉好的足球投注网站过程 12 3.2.3 开机节目播放过程 13 3.3 界面设计 13 3.3.1 一周指南界面 13 3.3.2 节目管理界面 14 3.4 功能设计 15 3.4.1 DMUX部分设计 15 3.4.2 一周指南功能 16 3.4.3 节目管理功能 19 3.4.4 遥
