在数字电视逐步取代模拟电视的趋势下,数字电视的运营,必须有一个功能强大的用户管理系统作为支撑。针对小型运营商及客户群特点,实现一种小型数字电视用户管理系统。这套系统使用SQL Server 2008数据库系统进行数据库管理,采用Windows Forms客户端窗体开发工具进行客户端开发,使用TCP协议来实现SMS系统与条件接收系统的通信,设计了CA应用接口通信协议框架、消息报文结构、消息参数类型语法结构、通信会话流程。%Digital TV replaces Analog TV gradually.So,the operation of a Digital TV system must be suppor-ted with a powerful user management system.This paper uses the SQL Server 2008 database system to achieve the management of data.The use of Windows Forms client form development tool for client development.The TCP protocol is used to realize the communication between SMS system and conditional access system.We de-sign CA application interface communication protocol framework,message structure,message parameter type syntax structure,communication session process.
