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.
