Subscriber Management System Of Digital Television

The integral translations of digital television in each city have been developed since it was carried out in the city of Qingdao in 2003.In recent years, the key words in the present article (for example:set-top box, digital television, and SMS) have also attracted great interests in broadcasting industry. It is necessary to form a powerful system in the order of the administration of millions of users and the management of various products and ever increasing value-added service. In this paper, we focus on subscriber management system (SMS) of digital TV.SMS can be divided into nine subsystems, including product, user, equipment, accounting, report, smart card service, classification management, and system management subsystems.In our research, we combined the MVC model and J2EE.The interface and logic business were completely separated. As a result, there is mutual noninterference in the system architecture.The system employs multi-tier based structure. Browser provides visual graphic interface; Web Server responds to the requests of the clients; Application Server Processes application, computation and data operation; Database server stores and administrates information. The implementation of multi-tier structure enables the system to have distinguished quality of flexibility, currency, compatibility and maneuverability. The system applied java encrypt technology to accomplish client information encrypt and registration, and applied connection pool technology to enhance the database operation efficiency.
