The Design And Implementation Of Digital TV Prepaid Card Software

Electronic technology is a fast developing technology,digital TV industry is one of them.The charge status of digital TV industry as the cause of proposed the digital TV industry charges such as private pull random access signals,evasion of users,the collection subscription cost problem of higher labor costs;Chengdu wireless digital TV system as an example,from the objective difficult charge,the withdrawal from circulation of funds difficult phenomenon,analyzes the voice recharge card system is superior to the traditional pricing model,as well as for the necessity of digital TV broadcasting industry,and lists the industry in the use of some of the recharge system.The DONJIN D801 A sound card and outside the module as the hardware foundation,SQL Server 2000 database platform,and butt with KINGVON 3.0 conditional access system(CAS)and subscriber management system(SMS),using Visual Basic language,research and development a set of digital television prepaid card software,the use of wired or wireless telephone communication network,connected the IVR card with digital TV network,with the conventional encryption card as the medium,with the relevant instructions for authorization.The second chapter describes the system design requirements of the relevant technical basis and equipment,and the system needs analysis,system needs to achieve the function module: IVR voice response,prepaid card,prepaid card to generate authentication,SMS interface,database storage etc..The third chapter detailed description of the related design of the whole system.Voice recharge system mainly includes system monitoring and recharge card system,recharge monitoring system and IVR voice card hardware matching,receives the data and function call processing,processing results converted to specify the voice through the telephone network feedback to the user,to direct the operation of users recharge,the final completion of charging and payment.Prepaid card issuing system also includes the recharge card generation,distribution,password authentication,authentication,database creation and data definition module.Then give some function expansion planning of this system,planning the next stage to increase network payment function,the related modules and the structure of planning,the definition of the corresponding interface,clear network payment process,design of network payment platform play foundation,to meet today with the rapid development of network to meet a wide range of user groups use.After the system is designed for detailed debugging and testing,routine testing,stress testing,and for testing in the wireless digital TV system in Chengdu City,to find and solve the system part of the BUG.Eventually completed the project goal,achieve the user dials the specified phone recharging system,user input card and prepaid card password can be instant authorization.Solve the current main problems of radio and television,but also solve the problems of remote users,convenient,efficient and safe.
