嵌入式数据库SQLite在数字电视EPG系统中的应用

摘要

分析了嵌入式数据库SQLite架构,介绍了EPG数据来源,提出将SQLite运用于数字电视接收终端,并结合实例说明了数字电视机顶盒中使用SQLite构建EPG数据库和对EPG数据进行管理的方法.SQLite数据库的应用,提高了数字电视系统处理数据的效率,节省了处理数据时所占用的资源.%By analyzing the structure of embedded database Sqlite and presentation of EPG data sources,the application of SQLite in digital TV receiver terminal is introduced. SQLite can be used in digital TV STB to build up EPG database and manage the EPG data. The application of Sqlite database can increase the data processing efficiency of digital TV system,and save the data processing resources.
