Digital Tv User Management System - Data Interface System Design And Realization

The Subscriber Management System (SMS) for Digital TV (DTV) is a System for supporting operation, which is use of digital technology and network communication licensing subscription DTV products. Because the market regulation and various improvements in technology,SMS already has a considerable wealth of functions after several years of development. However, along with the popularity of digital television and the user's substantial growth, a single-fixed system didn't meet the needs of the growing in the development process. Therefore, users need DTV system more comprehensive to adapt to different local needs.The subjects completed Data interface system in SMS ,which provide bank interface and add_valued business interface. That is to say, subscribers can conduct business in the bank or enjoy many different programs. SMS involved in many user account information, so its safety and practicality is the primary task to solve the problems. In the design and implementation of the system, we analyzed the limitations in current broadcast television market, and give full consideration to the diverse needs of users and system performance requirements. So we adopted three layer system architecture based on web service and object-oriented database technology. And in order to protect data security, we used Socket encapsulated TCP / IP packet communication methods. Thereby we can ensure the users quick and easy to conduct business and make the accounts exchanges between bank and SMS smoothly and safe.This paper introduced the bank interface and the module of add_valued business. From design ideas to the concrete realization of module division has done a detailed, and functions of each part have been verified accordingly.
