DMB (Digital Multimedia Broadcasting) Voice EPG Application

Recently, mobile TV is becoming a mainstream service in mobile broadcasting scenario, where requires lots of mobile factors such as robust transmission, high performance and easy interface and so on. As mobile broadcasting services are being highlighted, the easy interface and appropriate application are increasingly in demand. In most mobile scenarios, where users may actually share their attention with other concurrent tasks and where highly integrated devices may have very limited physical characteristics, intuitive man-machine interfaces are key factors to successful applications. The EPG, an essential application in most digital broadcasting systems, is also not free from the easy interface and mobile factors. The conventional GUI driven EPG solutions are, sometimes, not appropriate to the mobile system aiming the mobile TV and rich interactive data services. In this paper we present voice enabled EPG application that features voice user interaction and dialog technology allowing the user to have a speech interaction with the terminal in navigating and searching any program or service. We illustrate an overall service framework addressing the content delivery and consuming architecture fitted to the DMB environment. Moreover, we propose and implement an agent platform by profiling the elements of VoiceXML and extending EPG related elements to enable the EPG functionalities
