3G Based Multimedia Information Publishing Platform

In recent years,as the growth of the Internet and multimedia technology,the technologyof multimedia information publication has been widely obtained in public places. Thetechnology,quickly,efficiently,vividly disseminates information and news,is a symbol of CityInformatization. It can help the enterprise improve their service,and promote their conceptand products. The multimedia information technology not only brings in lots of opportunitiesbut also creates a new business model,such as touch media.The technology is composed by two parts： Information Publishing Platform andMultimedia Player Terminal,both have some shortages. The former is imperfect in contentarrangement and the timeliness of the information publication. The latter is still lack ofinteractions,while has some problems in3G network access and optimization.The design and realization of multimedia information publication system in this thesis hasbeen analyzed in three aspects： system software,application software and communicationtechnology.First,in consideration of the background and meaning of this thesis,it has analyzed theshortages of the current system in the world,decided the direction of system development,andintroduced technologies relative to this system.Second,based on the arrangement and analysis of the building system that on the way,thefunction modules are divided as follows： application software that including contentdistribution module and monitoring module; system software as display module that supportsLinux and Embedded Linux system;communication technology as communication modulethat solves the communication problem between systems.Third,it has put emphasis on introduction of the agreement of the communication moduleand realization of the display module,while tested the system and defined the testing result.Last,in conclusion,it analyzes the imperfectness of the current system and defines theimproving direction of the building system.
