The E-business Model Based On CATV Wide Band The Research And Implement Of The Controller & View Layers Of Center Platform

With the development of CATV technology, the CATV network has become the new kind of wide band. The applications based on CATV technology is becoming more and more recognized and attended. For example: the CA system based on CATV, the CATV increment service system based on bidirectional HFC. On the basis of a special-endowed network program of Yunnan Technology Bureau-The Interact Open Service Platform of CATV, this paper is a part production of the distributed e-business TV supermarket using J2EE technology based on CATV network.The research methods applied in the paper are as follows:First: To analyze the actuality of the current CATV technologies, and to discuss its' future and develop tendency. Second: To research the current e-business model, and to discuss the e-business model that fit for CATV network. Third: To compare synthetically with the current technologies of program development, and take the J2EE technology as our basic technology of program development. Forth: According the feature of CATV network, to develop the TV supermarket that can run on the CATV network.The emphasis of this paper is to build the controller layer and view layer of TV supermarket. The core is framework research in J2EE. Two main research results of the paper are as follows.First: Implemented the controller layer which has better scalability, maintainability and reusability using J2EE framework.Second: Using XML in controller layer, which made the controller layer can control the whole flow of the program through the XML deployment files, implemented the modules' reusability. In view layer, applied the JSTL technology which made the modules of the system can choose view framework templates flexibly, and made the system has flexible and uniform page style.The paper not only researched the controller layer and view layer in theory, but also implemented the scalability of controller layer and the flexibility of view layer. The controller layer with good portability implemented in this system may be the base to develop the distributed systems.
