摘　　要：为提高信息发布系统的发布效率,设计和实现了一个面向机顶盒的信息发布系统,该系统由信息中心、控制服务器群和机顶盒终端3部分组成,该系统通过控制信息与信息数据的分开传输实现可扩展性,并且通过硬件冗余、安全套接字(secure socket layer,SSL)等方法来提高系统的可用性、可靠性。系统还进一步通过优化文件分发算法来提高传输效率。实验测试结果表明,该信息发布系统能在较低硬件配置的情况下,为大量终端提供高质量的信息显示服务。该系统已在上海、山东等地银行、酒店行业中推广使用。The set-top box （STB） based scalable information publication system is designed and implemented to improve publication system efficiency. This system consists of application server, central instances for STB groups and terminals. Separation of control logic and data transmission is used together with hardware redundancy and SSL to improve system scalability, reliability and usability. Data transmission is optimized to supporta large number of terminals. Evaluation result shows that this system could provide high-quality information display service at a relative lower hardware cost. This system has been applied in retail stores, restaurants in Shanghai, Beijing and Shandong.
