Research And Implementation Of The Data Management In DVB Digital Television Middleware

Telecast plays an important role for people to understand the world, acquireinformation, live and entertain in our daily lives. It’s one of the necessary facilities inour lives and amusements. The emergence of digital television is one of the mostimportant things in history of telecast. It can not only improve the quality of audio andvideo but also change the traditional mode of watching TV. It can provide manyincremental operations, such as television website, Video-On-Demand, remoteeducation and information services.With the development of information technology and the higher requirement fortelevision pastime, interactive television attracted more and more attention. Forrealizing interactive television services, we must adopt digital television middlewaretechnology.Digital television middleware is a kind of system software that residesbetween the application and the underlying operation system. It can shield softwaredevelopers from low-level platform details by providing a set of standard applicationinterface for digital television. The significance ofemergence of middleware is thatdevelopersdo not have to consider differences amongdifferent underlying hardwaretoomuch, and can port software and code easily and simplify the development process ofthe top software programs, saving the cost of R&D of digital TV.Now, digitaltelevision gets more and more manufacturer’s attention. The research on digitaltelevision middleware in the overseas has gained some evolvement. However, it hasbeen done later in our country. So, the research and development of our own digitaltelevision middleware have an important academic and applied significance.The research background of this article is based on research and development of acorporate project. In this paper, digital TV middleware of which are realized.Thispaper first introduces the concept of digital TV middleware, and then gives a comparative study of today’s middleware standards. According to the middlewarestandard at home, this article designs a model of the middleware, and gives thein-depthresearch and design of the Data Management mode. The designs above havebeen tested at a digital TV platform, and get the desired results.
