The Design And Implement Of The Information Platform Database In Digital TV

With the constant development of the social culture, economy, and at the same time with the multimedia technology, the constant development of communication technology and software and hardware technology, the simple analog TV programs has been already very difficult to meet demands of the masses of audiences. People want to obtain more program source to come according to one's own demand to hope, and have other function that products do not can finish just only originally to realize through TV. The digital TV is arisen at this time, among them the value-added service of the digital TV is a light spot of the digital TV, in this condition, the data of the digital TV broadcast the system had arise. The focus of the data broadcasting system lies in developing various kinds of concrete, detailed, practical, novel, user -oriented concrete business. From the whole function of system, it can be divided into system server and client. The main function of the server (or front) is to finish the inputting and broadcasting of the data; The function of the client (or terminal) is the information appears. In each of system, data of broadcast operate procedure to launch around this key link of the database all the time in fact. This paper has introduced the systematic procedure in the data broadcasting system mainly. The database based on DVB system operates course and key technology. The information of broadcasting in DVB data can come from such data sources as Internet, stock exchange, online shop, etc., and can compile the information according to the method to develop Internet's websites too. No matter the diversification of the source of the data, will enter the database in this container finally,in order to let the front operator dispatch. Recommend technology sum up, realization scheme and meaning, information of platform, data of broadcast at first among this paper, database technology application and meaning in the information platform. Then as a means of two pieces of representative business in the actual development of the information platform -the news and traffic are examples, the design of the database and scheme of realizing. So this paper studies the database in the data broadcasting information of the STB serve to realize, so as to discuss to the scheme of realization based on DVB-C of this system and the prospect.
